Introduction

The extent of change in Patient Reported Outcome Measures (PROMs) required to meet surgeon-defined satisfactory outcomes after isolated medial patellofemoral ligament reconstruction (MPFL-R) has not been reported. The primary aim of the study was to define the threshold value of maximal outcome improvement (MOI) in PROMs associated with surgeon-defined satisfactory postoperative outcomes. The secondary aim was to identify the most effective PROM in predicting these outcomes and to evaluate the factors associated with it.

Methods

This is a retrospective review of prospectively collected data as part of the JUPITER multi-center study. Receiver operating characteristic curves were calculated to determine threshold values for MOI for 4 commonly used PROMs - Banff Patella Instability Instrument (BPII 2.0), Pediatric International Knee Documentation Committee (Pedi-IKDC), Knee Injury and Osteoarthritis Outcome Score (KOOS) and Kujala score - associated with surgeon-defined satisfactory outcomes. Multivariate analyses were performed to determine preoperative, intraoperative, and radiographic factors associated with satisfactory outcomes.

Results

284 patients were included in the analysis. 183 (66.9 ​%) patients achieved surgeon-defined satisfactory outcomes. For MOI, achieving an improvement in BPII 2.0 score greater than 65.86 ​% (Area under the curve (AUC): 0.75; CI: 068–0.80; p ​< ​0.0001) and in the Kujala score greater than 85.18 ​% (AUC: 0.69; CI: 0.62–0.75; p ​< ​0.0001) was associated with a satisfactory outcome. BPII 2.0 had the highest AUC while Kujala had the least AUC (p ​= ​0.04). Multiple logistic regression analysis showed that first-time dislocation or having 10 or more dislocations prior to surgery significantly decreased the odds of achieving satisfactory postoperative outcomes (OR 0.12, p ​= ​0.002). None of the radiographic parameters were associated with outcomes.

Conclusion

MOI serves as an important measure to gauge clinical success after isolated MPFL-R. The study sets MOI thresholds for four commonly used PROMs, thus correlating patient- and surgeon-defined satisfactory outcomes after isolated MPFL-R. BPII 2.0 had good discriminative ability while Kujala had the least. The study identifies that isolated MPFL-R after first-time dislocation or after 10 or more dislocations are associated with decreased odds of satisfactory outcomes.

简介:在孤立的髌股内侧韧带重建(MPFL-R)后,达到外科医生定义的满意结果所需的患者报告结果测量(PROs)的变化程度尚未报道。该研究的主要目的是确定与外科医生定义的满意术后结果相关的PROs的最大预后改善(MOI)的阈值。第二个目的是确定预测这些结果最有效的PRO,并评估与之相关的因素。方法:作为JUPITER多中心研究的一部分,这是一项前瞻性收集数据的回顾性综述。计算受者工作曲线以确定4种常用PROs的MOI阈值- Banff髌骨不稳定仪(BPII 2.0),儿科国际膝关节文献委员会(Pedi-IKDC),膝关节损伤和骨关节炎结局评分(oos)和Kujala评分-与外科医生定义的满意结果相关。进行多变量分析以确定术前、术中和影像学因素与满意结果的相关性。结果:284例患者纳入分析。183例(66.9%)患者获得了外科医生定义的满意结果。对于MOI, BPII 2.0评分改善大于65.86%(曲线下面积(AUC): 0.75;Ci: 068 - 0.80;结论:MOI是衡量孤立性MPFL-R临床成功与否的重要指标。该研究为四种常用的MPFL-R设定了MOI阈值,从而将孤立性MPFL-R后患者和外科医生定义的满意结果相关联。BPII 2.0具有较好的辨别能力,而Kujala的辨别能力最差。研究发现,首次脱位或10次以上脱位后发生孤立性MPFL-R与满意结果的几率降低有关。证据等级:前瞻性收集数据的4级回顾性评价。

The posterolateral corner (PLC) of the knee is a key anatomical structure which provides varus and rotational stability to the knee joint. Injuries to the PLC pose a great challenge for orthopedic surgeons due to their complex nature. PLC injuries rarely occur in isolation, with up to 95% being associated with ligament tears. Surgical reconstruction is indicated in Grade III injuries, defined clinically as >10 ​mm lateral opening on varus stress and >10° external rotation on the dial test, supported by MRI magnetic resonance imaging findings.
Several techniques have been described for PLC reconstruction; however, the classic anatomic reconstruction described by LaPrade remains the gold standard, traditionally performed using an Achilles tendon allograft. In this video technique, we describe a modified LaPrade technique using peroneus longus and hamstring tendon autografts for PLC and posterior cruciate ligament (PCL) reconstruction, respectively, in a patient having tibia nail in situ for Type IIIb open fracture shaft of tibia. The peroneus longus tendon is fashioned into a Y-shaped construct and must be at least 250 ​mm long to perform this technique. The graft passage and fixation sequence are the reverse of the LaPrade technique. This method ensures anatomic fixation, independent tensioning, and secure fixation of each segment, thereby restoring the normal biomechanics of the knee.
膝关节后外侧角(PLC)是提供膝关节内翻和旋转稳定性的关键解剖结构。PLC损伤由于其复杂的性质,对骨科医生提出了巨大的挑战。PLC损伤很少单独发生,高达95%与韧带撕裂有关。III级损伤需要手术重建,临床定义为内翻应力下>0 mm外侧开口,刻度盘试验中>10°外旋,MRI结果支持。介绍了几种用于PLC改造的技术;然而,LaPrade描述的经典解剖重建仍然是金标准,传统上使用同种异体跟腱移植。在本视频技术中,我们描述了一种改良的LaPrade技术,使用腓长肌和腘绳肌腱自体移植物分别用于PLC和后交叉韧带(PCL)重建,用于胫骨钉原位治疗IIIb型胫骨开放性骨折。腓骨长肌腱被塑造成y形结构,必须至少250毫米长才能进行这项技术。移植物通道和固定顺序与LaPrade技术相反。该方法确保解剖固定、独立张紧和每个节段的安全固定,从而恢复膝关节的正常生物力学。

Introduction/objectives

Bouldering, a dynamic climbing discipline performed without ropes, is associated with high-energy ground falls. While most existing climbing injury literature has focused on the upper extremities, our data indicated an increasing number of complex knee injuries related to bouldering. This review was conducted to characterize the injury patterns sustained from ground falls during bouldering, and to compare the relative burden of these injuries with those sustained in other high-participation sports.

Methods

A retrospective case series was performed, including climbers who presented with knee injuries from ground falls during bouldering between March 2022 and October 2024. Patient demographics, injury mechanisms, ligamentous and meniscal pathology, as well as osseous or chondral damage were collected. The injuries were stratified by sex, age group, and injury complexity, including multiligament injury, meniscus tears, and osseous or chondral involvement. The bouldering-related injuries were then compared to institutional data from soccer and basketball, the two most common causes of sports-related knee injuries requiring surgery at the institution’s sports center.

Results

Nineteen patients were included, with a mean age of 27 ​± ​5.1 years. Of these, 15 (78.9 ​%) sustained combined anterior cruciate ligament and meniscus injuries. Surgical intervention was performed in 18 (94.7 ​%) patients. Multiligament knee injuries occurred in 4 (21.2 ​%) bouldering cases, accounting for 20 ​% of all multiligament knee injuries treated during the study period. Meniscus root tears were identified in 4 (21.1 ​%) bouldering cases, representing 22 ​% of all surgically treated meniscus root tears. Bone contusions consistent with pivot-shift patterns were observed in 52.6 ​% of patients, with cartilage fissuring and sulcus terminalis impaction in 10.5 ​% each. Compared to soccer and basketball, bouldering demonstrated a relatively higher proportion of complex knee injuries, despite lower participation volumes.

Conclusion

Ground falls during bouldering ground falls have been associated with a high proportion of complex knee injuries, including multiligament knee injuries, meniscus root tears, and injuries to both menisci. These injury patterns are believed to result from high-energy axial and rotational loading, and suggest the need for increased awareness, preventive strategies, and rehabilitation programs tailored to the sport.

介绍/目标:抱石是一种动态攀岩训练,没有绳索,与高能地面坠落有关。虽然大多数现有的攀岩损伤文献都集中在上肢,但我们的数据表明,与抱石有关的复杂膝关节损伤越来越多。这篇综述是为了描述抱石地面坠落造成的损伤模式,并将这些损伤的相对负担与其他高参与运动中造成的损伤进行比较。方法:采用回顾性病例系列,包括2022年3月至2024年10月期间因抱石地面坠落而出现膝盖损伤的登山者。收集患者的人口统计资料、损伤机制、韧带和半月板病理以及骨或软骨损伤。损伤按性别、年龄组和损伤复杂性分层,包括多韧带损伤、半月板撕裂、骨或软骨受累。然后将抱石相关的损伤与足球和篮球的机构数据进行比较,这两种最常见的运动相关膝盖损伤原因需要在该机构的体育中心进行手术。结果:19例患者入组,平均年龄27±5.1岁。其中15例(78.9%)持续前交叉韧带(ACL)和半月板合并损伤。手术干预18例(94.7%)。4例(21.2%)抱石患者出现多韧带损伤,占研究期间所有MLKI治疗病例的20%。4例(21.1%)抱石病例发现半月板根撕裂,占手术治疗半月板根撕裂的22%。52.6%的患者出现骨性挫伤,软骨裂和终末沟嵌塞各占10.5%。与足球和篮球相比,抱石运动显示出相对较高的复杂膝盖损伤比例,尽管参与人数较少。结论:抱石地面坠落与膝关节多韧带损伤、半月板根撕裂、双半月板损伤等复杂损伤的发生率较高。这些损伤模式被认为是由高能量的轴向和旋转载荷造成的,这表明需要提高意识,预防策略和针对运动的康复计划。证据级别:4级,案例系列。

Introduction

Retear after anterior cruciate ligament reconstruction (ACLR) has been reported between 6% and 31% of cases, resulting in worse outcomes and increased risk of post-traumatic osteoarthritis. This study investigated whether postoperative magnetic resonance imaging (MRI) assessment, clinical outcomes, and return-to-sport test findings can help identify patients at higher risk of early graft retear.

Methods

Retrospective analysis of 430 patients who underwent primary ACLR using hamstring autograft between 2017 and 2022, with a minimum follow-up of 12 months. Baseline characteristics, intraoperative, and postoperative information were collected. Graft signal, tunnel widening and positioning were assessed through a 12-month MRI. Patients who experienced early graft retear were compared with a matched cohort with a ratio of 1:4. Continuous variables were compared. Logistic regression and analysis of variance were used to identify risk factors and association with retear. p values ​< ​0.05 were considered significant.

Results

Of the 346 patients who met the inclusion/exclusion criteria, 19 experienced a graft rupture (5.4 ​%) after the 12-months follow-up. Of those, six patients were excluded due to missing postoperative 1-year MRI. Overall, 13 patients were included in the retear group and compared with 50 matched patients. The mean follow-up was 23.6 ​± ​4.2 months (range, 18–36 months). The 12-month MRI showed a greater signal-to-noise quotient (SNQ) in case of retear (2.93 vs 2.02; p ​= ​0.029). The analysis of variance showed a positive interaction between graft signal and retear (analysis of variance [ANOVA], p ​= ​0.028). Tunnel positioning was comparable between the groups, and not associated with retear. Similarly, tibial and femoral tunnel widening were comparable between the two groups and not associated with graft retear (ANOVA, p ​= ​0.733 and p ​= ​0.190). A greater proportion of patients had an anterior knee laxity >2 ​mm at one year in the retear group (83.3% vs 38.8 ​%, p ​= ​0.058). However, mean laxity was comparable (2.55 ​mm vs 1.35 ​mm; p ​= ​0.189). No differences were noted for clinical scores and return-to-sport testing.

Conclusion

Higher graft signal on MRI at 12 months, indicating poorer graft healing, is associated with early anterior cruciate ligament retear. Resonance imaging after ACLR could be used to guide the follow-up management. Further research is required to confirm these preliminary findings.

导读:据报道,前交叉韧带重建后再次撕裂的发生率在6%至31%之间,导致更差的结果,并增加了创伤后骨关节炎的风险。本研究调查了术后磁共振成像评估、临床结果和恢复运动测试结果是否有助于识别早期移植物再撕裂风险较高的患者。方法:回顾性分析2017 - 2022年间430例采用自体腘绳肌腱移植行原发性前交叉韧带重建术的患者,随访时间至少为12个月。收集基线特征、术中及术后信息。通过12个月的磁共振成像评估移植物信号、隧道拓宽和定位。经历早期移植物再撕裂的患者与匹配队列的比例为1:4进行比较。比较连续变量。采用Logistic回归和方差分析来确定危险因素及其与再撕裂的关系。结果:在符合纳入/排除标准的346例患者中,随访12个月后19例发生移植物破裂(5.4%)。其中6例患者因术后1年磁共振成像缺失而被排除。总的来说,13名患者被纳入再撕裂组,与50名匹配的患者相比。平均随访时间为23.6±4.2个月(18 ~ 36个月)。12个月的磁共振成像显示,再次撕裂的信噪比更高(2.93 vs 2.02; p=0.029)。方差分析显示移植物信号与再撕裂之间存在正交互作用(方差分析,p=0.028)。隧道定位在两组间具有可比性,且与再次撕裂无关。同样,胫骨和股骨隧道拓宽在两组之间具有可比性,与移植物再撕裂无关(方差分析,p=0.733和p=0.190)。在再撕裂组中,更大比例的患者在一年内出现前膝关节松弛>2mm (83.3% vs 38.8%, p=0.058)。然而,平均松弛度具有可比性(2.55 mm vs 1.35 mm; p=0.189)。临床得分和回归运动测试没有差异。结论:12个月磁共振成像显示移植物信号较高,表明移植物愈合较差,与早期前交叉韧带再撕裂有关。前交叉韧带重建后的磁共振成像可以指导后续治疗。需要进一步的研究来证实这些初步发现。证据水平iii:回顾性比较研究。

Introduction/Objectives

While the opportunity to provide medical care for elite-level professional and collegiate athletes is an honor and privilege, it does not come without a unique set of challenges. The team physician role continues to evolve and insights on today’s climate of team physicians’ care of elite athletes globally may be enlightening. As such, the purpose of this review is to provide a synopsis of the meeting’s key points and present the results of the survey to better delineate the effect of the medicolegal risk involved in the care of elite athletes.

Methods

An international and multidisciplinary group of experts on anterior cruciate ligament injury and sports medicine was chosen to participate on a panel at the 2024 Freddie Fu Panther Sports Medicine Symposium held at the University of Pittsburgh, Pittsburgh, Pennsylvania, USA, on June 6, 2024. The international panel included orthopaedic surgeons, primary care physicians, and scientists and focused on the medicolegal climate of sports medicine. Throughout the duration of the panel, a live questionnaire was provided to the audience, which included practitioners from 17 countries and 5 continents. The survey consisted of eight “yes/no” questions.

Results

Several themes emerged from the discussion, including differing medicolegal consequences based on geographic location, changes to documentation in response to litigation risk, and increases in personal stressors to physicians. Of the eight statements administered to the audience during the panel discussion, only three had greater than 50 ​% agreement. These statements included changes to practice based on the medicolegal climate and the effects of defensive practice on physicians and patients alike.

Conclusion

The risk of litigation in orthopaedic sports medicine surgery varies greatly based on the geographic location of the practice and is perceived to affect both patient care and providers alike. As the assessment of medical professional liability risk arising from the care of elite athletes continues to evolve, discussion among physicians, athletes, agents, and teams/clubs should be patient-centered, multidisciplinary, and undertaken with absolute professionalism, strong communication, and thorough documentation.
简介/目标:虽然有机会为精英水平的专业和大学运动员提供医疗服务是一种荣誉和特权,但它并非没有一系列独特的挑战。团队医生的角色继续发展,对团队医生照顾全球精英运动员的今天的气候的洞察力可能是有启发的。因此,本综述的目的是提供会议要点的摘要,并展示调查结果,以更好地描述精英运动员护理中涉及的医学法律风险的影响。方法:选择一个国际和多学科的前交叉韧带损伤和运动医学专家小组参加2024年6月6日在美国宾夕法尼亚州匹兹堡大学举行的“2024 Freddie Fu Panther运动医学研讨会”。国际小组成员包括骨科医生、初级保健医生和科学家,重点关注运动医学的医学法律环境。在小组讨论期间,向听众提供了一份现场问卷,其中包括来自17个国家和5大洲的从业者。该调查由8个“是/否”问题组成。结果:讨论中出现了几个主题,包括基于地理位置的不同医学法律后果,应对诉讼风险的文件变更,以及医生个人压力因素的增加。在小组讨论期间向听众提供的8个陈述中,只有3个有超过50%的同意。这些陈述包括基于医学法律气候的实践变化以及防御实践对医生和患者的影响。结论:骨科运动医学手术的诉讼风险在很大程度上取决于实践的地理位置,并且被认为对患者护理和提供者都有影响。随着对照顾优秀运动员所产生的医疗专业责任风险的评估不断发展,医生、运动员、经纪人和球队/俱乐部之间的讨论应该以患者为中心,多学科,并以绝对的专业精神、强有力的沟通和完整的文件进行。

Introduction/objectives

The purpose of this study was to examine the role of the posterior fan-like extension (PFLE) region of the anterior cruciate ligament (ACL) on ligament failure load. It was hypothesized that transection of the PFLE region would reduce the ACL load-carrying capacity.

Methods

With institutional approval, fifteen fresh-frozen human cadaveric knees were divided into two age-matched groups: intact ACL femoral insertion (ACL intact group, n ​= ​8) and the cut ACL fan-like extension (PFLE-cut group, n ​= ​7). In the PFLE-cut group, the border between the mid-substance insertion and the PFLE was identified at 90° of knee flexion, and the border was cut. All specimens were dissected down to the ACL and placed in an axial testing machine at 15° of flexion, and anterior tibial loading was applied until ACL failure.

Results

The failure (peak) load of the ACL intact group was 910.1 ​± ​473.3 ​N, which was significantly greater (P ​< ​0.05) than the failure load of the PFLE-cut group (409.5 ​± ​219.7 ​N). The displacement at the failure load of the ACL intact group was 21.7 ​± ​5.5 ​mm, which was significantly greater (P ​< ​0.05) than the 14.5 ​± ​4.9 ​mm failure load displacement of the PFLE-cut group.

Conclusion

Transection of the PFLE region of the ACL femoral footprint significantly reduced the failure load of the ligament under anterior tibial loading at 15° of flexion. The morphology of the ACL at the femoral insertion significantly affects the failure strength of the ligament. If ACL reconstruction grafts could be constructed to more closely mimic this geometry, they could potentially have increased failure strengths and reduce failure rates.

简介/目的:本研究的目的是研究前交叉韧带(ACL)后扇形延伸区(PFLE)对韧带失效负荷的作用。假设PFLE区域的横断会降低ACL的承载能力。方法:经机构批准,将15例新鲜冷冻人尸体膝关节分为两组:完整的ACL股骨插入组(ACL完整组,n=8)和切开的ACL扇形延伸组(PFLE cut), n=7)。在PFLE切割组中,在膝关节屈曲90°处确定中间插入物与PFLE之间的边界,并切割该边界。将所有标本解剖至前交叉韧带,置于15°弯曲的轴向试验机中,胫骨前负荷直至前交叉韧带失效。结果:ACL完整组的失效(峰值)负荷为910.1±473.3 N,明显大于PFLE切割组的失效负荷(409.5±219.7 N) (p < 0.05)。ACL完整组在破坏载荷下的位移为21.7±5.5 mm,显著大于PFLE Cut组的破坏载荷位移14.5±4.9 mm (p < 0.05)。结论:在屈曲15°的胫骨前负荷下,股骨前交叉韧带PFLE区域的横断可显著降低韧带的失效负荷。股骨止点前交叉韧带的形态显著影响韧带的失效强度。如果ACL重建移植物可以更接近地模仿这种几何形状,它们可能会增加失败强度并降低故障率。证据等级:不适用。

Introduction/objectives

In recent years, the number of primary anterior cruciate ligament reconstructions (ACLRs) has increased, accompanied by an increase in revision anterior cruciate ligament reconstructions (RACLRs). Residual anterolateral knee instability has been identified as a major contributor to graft failure. Consequently, lateral extra-articular procedures (LEAPs), particularly modified Lemaire tenodesis, have gained interest in the management of high-grade anterolateral rotational instability in RACLR. The aim of this study was to evaluate the clinical outcomes of patients undergoing combined RACLR and modified Lemaire tenodesis with soft anchor fixation. The hypothesis was that this fixation could lead to good results in terms of clinical outcomes at a minimum follow-up of two years.

Methods

A retrospective review of consecutive patients with failed primary ACLR and high-grade anterolateral rotational instability (side-to-side difference >5 ​mm, pivot shift ≥2+) was performed. All patients underwent an outside-in femoral tunnel technique for doubled semitendinosus and gracilis tendon ACLR, and a 2.6-mm knotless suture anchor was used for Lemaire fixation. Postoperative rehabilitation allowed for immediate weight bearing and progressive range of motion. Patients were evaluated clinically and radiographically at 3 and 6 weeks and at 3, 6, 12, and 24 months. Outcome measures included Lachman and pivot-shift tests, Rolimeter measurements, Tegner Activity Scale, Lysholm score, and subjective and objective International Knee Documentation Committee (IKDC) scores. Also, radiographic analysis was performed at the last follow-up.

Results

The final population comprised 15 patients. At a minimum of 2 years’ follow-up, one patient (6.6%) experienced graft failure. Most patients (10/15) achieved normal (Grade A) IKDC objective scores, with significant improvements in side-to-side differences and patient-reported outcomes. No intraoperative tunnel convergence was observed, and no additional hardware removal or reoperation was required.

Conclusions

A combined RACLR with modified Lemaire extra-articular tenodesis using soft anchor fixation provided favorable clinical and radiographic results in patients with high-grade anterolateral rotatory knee instability without significant complications.

前言/目的:近年来,原发性前交叉韧带重建(ACLRs)的数量有所增加,同时ACLRs的翻修也有所增加。残留的膝关节前外侧不稳定被认为是移植物失败的主要原因。因此,外侧关节外手术(LEAPs),特别是改良Lemaire肌腱固定术,在ACLR翻修中对高度前外侧旋转不稳定的管理产生了兴趣。本研究的目的是评估接受改良ACLR和改良Lemaire肌腱固定术联合软锚固定的患者的临床结果。假设这种固定可以在至少两年的随访中获得良好的临床结果。方法:对原发性ACLR失败和高度前外侧旋转不稳定(侧侧差异bbb50 mm,枢轴移位≥2+)的连续患者进行回顾性分析。所有患者均采用由外至内的股骨隧道技术治疗双半腱肌和股薄肌腱ACLR,并使用2.6 mm无结缝合锚钉进行Lemaire固定。术后康复允许立即负重和进行性活动范围。在第3周和第6周以及第3、6、12和24个月时对患者进行临床和影像学评估。结果测量包括Lachman和pivot-shift测试、Rolimeter测量、Tegner活动量表、Lysholm评分以及主观和客观的国际膝关节文献委员会(IKDC)评分。最后一次随访时进行影像学分析结果:最终人群由15例患者组成。在至少2年的随访中,1例患者(6.6%)出现移植物衰竭。大多数患者(10/15)达到正常(A级)IKDC客观评分,侧对侧差异和患者报告的结果显着改善。术中未观察到隧道收敛,也不需要额外的硬体移除或再次手术。结论:ACLR联合改良Lemaire关节外肌腱固定术使用软锚固定为高度前外侧旋转性膝不稳患者提供了良好的临床和影像学结果,且无明显并发症。证据等级:四级。

Introduction/Objectives

Legg-Calvé-Perthes disease (LCPD) leads to complex hip deformities that often result in femoroacetabular impingement (FAI). While traditional open surgeries have been used to address these deformities, hip arthroscopy has emerged as a minimally invasive alternative. However, the factors determining successful outcomes in arthroscopic management of LCPD-related FAI remain poorly defined. The aim of this study was to compare clinical outcomes between successful and failed cases following hip arthroscopic surgery for FAI secondary to LCPD and identify factors associated with treatment failure to optimize patient selection.

Methods

We retrospectively analyzed patients who underwent hip arthroscopy for FAI secondary to LCPD from 2011 to 2023. Patients with less than 2-year follow-up or incomplete records were excluded. Treatment failure was defined as requiring revision surgery, experiencing complications, or failing to achieve both the minimal clinically important difference (9.1 points) and Patient-Acceptable Symptom State threshold (72 points) on the modified Harris Hip Score. We evaluated patient characteristics, clinical outcomes, radiographic measurements including lateral center-edge angle (LCEA) and vertical-center-anterior angle (VCAA), preoperative radiographic severity using Tönnis grade, lateral pillar classification, and Stulberg grade and compared these factors between success and failure groups.

Results

The study included 15 hips in 14 patients. Nine hips achieved successful outcomes, while six hips were considered failures. The failure group was statistically significantly older (35.5 years versus 20.3 years, P ​= ​0.047) with decreased acetabular coverage, showing smaller LCEA (19.3° versus 30.2°, P ​= ​0.046) and VCAA (14.7° versus 33.3°, P ​= ​0.033). The failure group demonstrated higher frequencies of preoperative Tönnis grade ≥2, lateral pillar classification ​≥B, and Stulberg grade ≥4, indicating more severe degenerative changes and deformity. No statistically significant differences were observed in gender distribution or duration of symptoms between the groups.

Conclusion

Forty percent of patients experienced treatment failure after hip arthroscopic surgery for FAI secondary to LCPD. Advanced age, decreased acetabular coverage, and severe preoperative radiographic changes were associated with treatment failure. These findings suggest careful patient selection based on these factors is crucial for successful arthroscopic treatment in this patient population.

简介/目的:legg - calv - perthes病(LCPD)导致复杂的髋关节畸形,通常导致股髋臼撞击(FAI)。虽然传统的开放性手术已被用于治疗这些畸形,但髋关节镜检查已成为一种微创替代方法。然而,关节镜下治疗lcpd相关FAI成功的因素仍不明确。本研究旨在比较髋关节镜下手术治疗LCPD继发FAI成功和失败病例的临床结果,并确定治疗失败的相关因素,以优化患者选择。方法:回顾性分析2011年至2023年因LCPD继发FAI接受髋关节镜检查的患者。随访时间少于2年或记录不完整的患者被排除在外。治疗失败被定义为需要翻修手术,出现并发症,或未能达到最小临床重要差异(9.1分)和患者可接受症状状态阈值(72分)。我们评估了患者的特征、临床结果、放射学测量(包括侧中心边缘角(LCEA)和垂直中心前角(VCAA))、术前放射学严重程度(Tönnis分级、侧柱分级和Stulberg分级),并在成功组和失败组之间比较了这些因素。结果:该研究包括14例患者的15个髋关节。9个髋部获得成功,6个髋部被认为是失败的。失败组年龄较大(35.5岁比20.3岁,P = 0.047),髋臼覆盖率下降,LCEA(19.3°比30.2°,P = 0.046)和VCAA(14.7°比33.3°,P = 0.033)较小。失败组术前Tönnis分级≥2,侧柱分级≥B, Stulberg分级≥4的频率较高,表明退行性改变和畸形更为严重。两组间在性别分布或症状持续时间方面没有统计学上的显著差异。结论:40%的患者在髋关节镜下手术治疗继发于LCPD的FAI后治疗失败。高龄、髋臼覆盖率下降和术前严重的影像学改变与治疗失败有关。这些发现表明,在这些因素的基础上仔细选择患者对于这类患者的关节镜治疗成功至关重要。证据等级:三级。

Posterior dislocation of the sternoclavicular joint (SCJ) is a rare clinical condition requiring surgical management. Various surgical techniques have been described in the literature, but those involving bone tunnels carry an increased risk of residual instability and iatrogenic fractures. We present a novel surgical technique for the management of both acute and chronic posterior SCJ dislocations, based on a figure-of-eight configuration with autograft, which ensures joint stability while preserving its natural mobility. Furthermore, the use of a single clavicular tunnel oriented orthogonally to two sternal tunnels creates a highly stable three-dimensional construct and reduce iatrogenic fractures.
摘要胸锁关节后路脱位是一种罕见的临床疾病,需要手术治疗。文献中描述了各种手术技术,但涉及骨隧道的手术会增加残余不稳定和医源性骨折的风险。我们提出了一种新的手术技术,用于治疗急性和慢性后路SCJ脱位,基于自体移植物的8字形结构,在保证关节稳定性的同时保持其自然活动能力。此外,使用与两个胸骨隧道垂直的单个锁骨隧道可形成高度稳定的三维结构并减少医源性骨折。

Comparable clinical outcomes after conversion total knee arthroplasty following high tibial osteotomy and primary total knee arthroplasty: A matched cohort study 胫骨高位截骨和初次全膝关节置换术后转换全膝关节置换术的比较临床结果:一项匹配队列研究。

Introduction/Objectives

Knee osteoarthritis (OA) leads to pain and functional decline. While total knee arthroplasty (TKA) is a definitive treatment, high tibial osteotomy (HTO) offers a joint-preserving alternative for younger patients with malalignment. However, patients with HTO may eventually require conversion to TKA. This study aimed to compare clinical, functional, and patient-reported outcome measures (PROMs) of patients undergoing TKA after a prior medial opening wedge HTO to a matched cohort who had a primary TKA, with follow-up at ≥12 months.

Methods

This retrospective cohort study used data from The Knee Institute, Sydney, Australia. Patients converted from HTO to TKA were matched 1:1 to primary TKA patients based on age, sex, surgeon, body mass index, medial compartment OA, and approximate year of surgery. Inclusion criteria were TKA between 2011 and 2023, prior HTO in the same knee, both procedures by one of three fellowship-trained orthopaedic surgeons; and ≥ one year of follow-up. Data collected included the Oxford Knee Score (OKS), the Veterans RAND 12-Item Health Survey (VR-12), range of motion (ROM), hospital stay, and the Caton–Deschamps index (CDI). Fifty-one converted TKA patients were matched. Statistical analysis used paired t-tests, Mann–Whitney U, chi-square, and Fisher’s exact tests.

Results

Both groups showed statistically significant postoperative improvements in the OKS and the VR-12 physical scores (p ​< ​0.01), with no statistically significant difference between groups. ROM improved in both groups; flexion was slightly higher in the primary TKA group but not statistically significant. Patella baja was more frequent in the HTO-to TKA group; however, this was not statistically significant (p ​= ​0.054). Both groups had a median hospital stay of 5 days; however, the HTO-to-TKA group demonstrated a statistically significant distribution shift toward longer stays.

Conclusion

Conversion from HTO to TKA yields comparable clinical and functional outcomes to primary TKA. These findings emphasize the effectiveness of TKA after HTO and the importance of careful preoperative planning in this patient population.

目的:膝关节骨关节炎(OA)导致疼痛和功能下降。虽然全膝关节置换术(TKA)是一种确定的治疗方法,高胫骨截骨术(HTO)为年轻患者提供了一种保留关节的选择。然而,HTO患者最终可能需要转换为TKA。本研究旨在比较先前内侧开口楔形HTO后接受TKA的患者的临床、功能和患者报告的结果测量(PROMs),并随访≥12个月。方法:这项回顾性队列研究使用了来自澳大利亚悉尼膝关节研究所的数据。根据年龄、性别、外科医生、BMI、内侧室骨关节炎和大约手术年份,将从HTO转换为TKA的患者与原发TKA患者进行1:1的匹配。纳入标准为2011 - 2023年间的TKA,同一膝关节有HTO病史,两种手术均由三名接受过奖学金培训的骨科医生之一进行;随访≥1年。收集的数据包括牛津膝关节评分(OKS)、退伍军人兰德健康调查(VR-12)、活动范围(ROM)、住院时间和卡顿-德尚指数(CDI)。51例TKA患者被匹配。统计分析使用配对t检验、Mann-Whitney U检验、卡方检验和Fisher精确检验。结果:两组术后OKS和VR-12身体评分均有统计学显著改善(结论:从HTO转换为TKA的临床和功能结果与原发性TKA相当。这些发现强调了HTO后TKA的有效性,以及在这类患者中仔细的术前计划的重要性。证据等级:3;
