Multidirectional distal femoral malunion and limb shortening lead to functional deficit and decreased quality of life. A corrective osteotomy might be necessary to cope with these issues. The inception of computer-assisted planification and the introduction of patient-specific instrumentation based on 3D printing technology with personalized osteotomy guides provide high correction accuracy, effectiveness, time-saving, and reduce potential complications. The present study describes a case of correction osteotomy using this procedure in a young patient with multidirectional malunion who recovered from a painful joint with functional limitations at a two-year follow-up.

In this retrospective study, a technique consisting in neurolysis of the lateral retinacular nerve combined with a partial release through elliptic excision of the iliotibial band (ITB) is evaluated for efficacy in recalcitrant ITB friction syndrome and compared with results from other techniques reported in literature. From April 2014 to December 2017, 21 patients suffering from recalcitrant ITB friction syndrome were surgically treated with the aforementioned technique. 15 patients (15 knees) were available for a written retrospective reassessment after completion of a follow-up period of at least 12 months. Residual pain was scored using the Visual Analogue Scale (VAS). The functional outcome was evaluated by two patient reported outcome measurement scales (PROMs), the Lysholm and the International Knee Documentation Committee (IKDC) score. Return to sport was analysed by duration of the inactivity period as well as by the Tegner score. Overall satisfaction was evaluated using a modified Boyden scale. At final follow-up of one year, the performed intervention resulted in a pain reduction (VAS 4.2 (1-8) to 1.4 (0-6)) and improved knee function (Lysholm 59.53 to 87.73, IKDC 75) with return to sport (Tegner 4.3 to 5.4) after a median of 23.8 weeks (6 to 52). Twelve patients reported good or excellent results (80%) at final follow-up, and 12 patients (80%) would undergo surgery again, if necessary. The treatment of recalcitrant ITB friction syndrome by combining neurectomy of the lateral retinacular nerve with elliptic excision of the ITB resulted in good to excellent results in 80% of treated cases with return to sport in 93%.

Diminutive data is available on the outcome of several previously used total ankle replacement implants. The purpose of this study was to investigate the medium-term functional and radiological outcome and implant survival of the CCI Evolution implant. Consecutive series of 40 ankles operated in our hospital with primary TAR using the CCI Evolution implant in 2010-2013 were available for follow-up. The prospective clinical and radiographic data including the Kofoed score, subjective satisfaction and standard radiographs were collected preoperatively and at fixed time-points postoperatively. A CT was obtained in cases where osteolysis or loosening were suspected. The improvement of the Kofoed score and subjective satisfaction were statistically significant (p<0.0001). The implant survival was 97% (95% confidence interval (CI) 81%-100 %) at 5 years, and 81 % (95% confidence interval (CI) 60 %-92%) at 8 years. There were altogether 25 (64%) complications. Overall revision rate was 28% and failure rate 13%. The CCI implant outcome was not acceptable. The malposition of prosthetic components, subsidence, and peri-implant osteolysis were recorded often. Although the patient reported outcome measures improved, mostly due to positive changes in pain severity, overall revision and failure rates were high and comparable with previous findings of the CCI implant.

It was aimed to investigate the relationship between magnetic resonance imaging (MRI) measurements of trochlear and patellar morphology and grade 3-4 patellar chondromalacia. Grade 3-4 patellar chondromalacia group, and an age- and sex-matched control group with normal patellar joint cartilage were comprised. For trochlear morphology evaluation in MRI; sulcus angle, trochlear angle, lateral trochlear inclination angle and medial trochlear inclination angle were measured. For patellar morphology evaluation; patella trochlear ratio, insall-salvati ratio, modified Insall- Salvati ratio and Blackburne-Peel ratio were measured. Obtained measurements were statistically analyzed according to demographic characteristics. One hundred and twenty-five patients with chondromalacia and 125 controls participated. The sulcus angle and the trochlear angle were significantly higher in the patellar chondromalacia group (p<0.05). The lateral trochlear inclination angle was significantly less in the patellar chondromalacia group (p=0.011). There was no significant difference between the groups in terms of medial trochlear inclination angle (p=0.520). There was no significant difference between the groups in terms of patella-trochlear ratio (p=0.617). Insall-Salvati ratio was significantly higher in the patellar chondromalacia group (p=0.003). Modified Insall-Salvati ratio was significantly lower in the patellar chondromalacia group (p=0.001). The rate of Blackburne-Peel was significantly higher in the patellar chondromalacia group (p=0.004). Measurements of sulcus angle, trochlear angle, lateral trochlear inclination angle, Insall-Salvati ratio, modified Insall-Salvati ratio, Blackburne-Peel ratio have diagnostic value for grade 3-4 chondromalacia.

A key component in fast-track total knee arthroplasty (TKA) is early mobilization. Preoperative fasting might cause orthostatic hypotension and -intolerance which both can interfere with early mobilization. It was hypothesized that consuming a carbohydrate drink 2-3 hours prior to surgery is a viable option to reduce orthostatic hypotension, and as a result, improve rehabilitation. In this randomized controlled trial, all consecutive unilateral primary TKA patients were reviewed for eligibility. Exclusion criteria were American Society of Anesthesiologists (ASA) class above 3, older than 80 years of age, Diabetes Mellitus, and an insufficient comment of Dutch language. Patients were distributed in two groups. The control group was allowed to eat till 6 hours and drink clear fluids till 2 hours before surgery (standard treatment). The intervention group consumed, additionally to the standard treatment, a carbohydrate drink 2-3 hours before surgery. Blood pressure was measured both lying and standing as a measure for orthostatic hypotension during first time postoperative mobilization on day of surgery. A total of 168 patients were included. Prevalence of orthostatic hypotension in the control- and intervention group was 24 patients (34%) and 14 patients (19%) respectively, (p=0.05). Prevalence of orthostatic intolerance was 13 patients (19%) in the control group and 9 patients (13%) in the intervention group (p=0.32). No drink related adverse events occurred. In conclusion, taking a carbohydrate drink 2-3 hours before TKA significantly lowers the number of patients with orthostatic hypotension in early mobilization. However, the clinical relevance of the carbohydrate drink has to be studied further.

With the increase in the number of individuals participating in sports, anterior cruciate ligament (ACL) injuries are also increasing gradually and the number of patients requiring surgical treatment is increasing in parallel. The primary aim of this study was to investigate the relationship between the need for revision surgery and graft diameter following primary ACL reconstruction (ACLR) using hamstring autografts. The secondary aim of the study was to clarify relationships between anthropometric characteristics and graft diameter. Patients who underwent ACLR with hamstring autografts were included in this retrospective study. The age, body mass index, height, and weight of all patients were recorded preoperatively and the diameters of the grafts were recorded during surgery. The relationship between revision rate and graft diameter and the relationships between anthropometric measurements and graft diameter were investigated for these patients at least one year after surgery. This study included 58 people with graft diameters of ≤7 mm and 261 people with graft diameters of >7 mm. A statistically significant difference was found between the graft diameters of the group that needed revision surgery and the group that did not (p<0.001). A positive relationship was also found between the patient's height and graft diameter (r=0.168). In this study, it was found that the risk of ACL revision surgery increased by 5.5 times among patients with graft diameters of ≤7 mm. The positive relationship between the patient's height and graft diameter can make a significant difference in terms of the need for revision surgery.

Osteosarcoma (OS) is a malignant primary bone tumor with a high incidence. This study aims to construct a prognostic prediction model by screening the prognostic mRNA of metastatic OS. Data on four eligible expression profiles from the National Center for Biotechnology Information Gene Expression Omnibus repository were obtained based on inclusion criteria and defined as the training set or the validation set. The differentially expressed genres (DEGs) between meta- static and non-metastatic OS samples in the training set were first identified, and DEGs related to prognosis were screened by univariate Cox regression analysis. In total, 107 DEGs related to the prognosis of metastatic OS were identified. Then, 46 DEGs were isolated as the optimized prognostic gene signature, and a metastatic-OS discriminating classifier was constructed, which had a high accuracy in distinguishing metastatic from non-metastatic OS samples. Furthermore, four optimized prognostic gene signatures (ALOX5AP, COL21A1, HLA-DQB1, and LDHB) were further screened, and the prognostic prediction model for metastatic OS was constructed. This model possesses a relatively satisfying prediction ability both in the training set and validation set. The prognostic prediction model that was constructed based on the four prognostic mRNA signatures has a high predictive ability for the prognosis of metastatic OS.

Ankle fractures involving the posterior malleolus (PM) generally have worse prognosis. There is a trend towards it's direct fixation, yet the exact indications are a subject of debate. The purpose of our study was to present our treatment protocol and to discuss the advantages and limitations of the direct posterolateral and posteromedial approaches. We present a prospective series of 35 ankle fractures involving the PM, operated for a period of 4 years (2018-2022). Direct posterolateral approach was used in 20 ankles, 15 were operated via a posteromedial approach. Clinical and functional assessment was performed according to the criteria of AOFAS. 14 patients received an excellent score, 16 had good and the rest had an average score. The overall score was 85,4 (54-100). The average range of motion was 50° (15°-55°).Eight patients had superficial skin necrosis along the surgical incision. Thirteen patients need their fibular plates removed due to local irritation. Five patients, operated through a posterolateral approach, had lateral heel numbness suggestive of a sural nerve disfunction. PM is important for normal ankle kinematics. When it's direct fixation is considered appropriate, the safest and shortest route is optimal. It is determined by the preoperative CT. The posterolateral approach is more versatile, but lead to more complications in our study.

Open reduction and internal fixation of extended lateral column tibial plateau fractures through a tibial condyle osteotomy and limited arthrotomy with the use of free subchondral locking screws is a straightforward and safe technique. However, these free subchondral screws are enclosed in the subchondral bone and therefore virtually impossible to remove after bone healing. The question arises whether these free subchondral screws might hinder a future total knee arthroplasty. In order to refute this, we retrospectively reviewed all surgically managed tibial plateau fractures in our tertiary center during one year and assessed the number, position and configuration of these in situ subchondral screws and K-wires. In addition, we performed a cadaver study, wherein we prepared 7 tibial plateaus for a total knee arthroplasty tibial component placement with free subchondral screws in situ. In this experiment, we demonstrated that free subchondral screws do not interfere with total knee arthroplasty, but they can increase operative time in some cases. We also provide recommendations to avoid difficulties and potential complications.

Despite a fast-growing evidence-base examining the relationship of certain clinical and radiological factors such as smoking, BMI and herniation-type with rLDH, there remains much debate around which factors are clinically important. We conducted a systematic review and meta-analysis to identify risk factors for recurrent lumbar disc herniation (rLDH) in adults after primary discectomy. A systematic literature search was carried out using Ovid-Medline, EMBASE, Cochrane library and Web of Science databases from inception to 23rd June-2022. Observational studies of adult patients with radiologically-confirmed rLDH after ≥3 months of the initial surgery were included, and their quality assessed using the Quality-In-Prognostic-Studies (QUIPS) appraisal tool. Meta-analyses of univariate and multivariate data and a sensitivity-analysis for rLDH post-microdiscectomy were performed. Twelve studies (n=4497, mean age:47.3; 34.5% female) were included, and 11 studies (n=4235) meta-analysed. The mean follow-up was 38.4 months. Mean recurrence rate was 13.1% and mean time-to-recurrence was 24.1 months (range: 6-90 months). Clinically, older age (OR:1.04, 95%CI:1.00-1.08, n=1014), diabetes mellitus (OR:3.82, 95%CI:1.58-9.26, n=2330) and smoking (OR:1.80, 95%CI:1.03- 3.14, n=3425) increased likelihood of recurrence. Radiologically, Modic-change type-2 (OR:7.93, 95%CI:5.70-11.05, n=1706) and disc extrusion (OR:12.23, 95%CI:8.60-17.38, n=1706) increased likelihood of recurrence. The evidence did not support an association between rLDH and sex; BMI; occupational labour/driving; alcohol-consumption; Pfirmann- grade, or herniation-level. Older patients, smokers, patients with diabetes, those with type-2 Modic-changes or disc extrusion are more likely to experience rLDH. Higher quality studies with robust adjustment of confounders are required to determine the clinical bearing of all other potential risk factors for rLDH.
尽管研究某些临床和放射学因素(如吸烟、BMI和疝症类型)与rLDH的关系的证据基础迅速发展,但关于哪些因素在临床上很重要,仍有很多争论。我们进行了一项系统综述和荟萃分析,以确定成人初次椎间盘切除术后复发性腰椎间盘突出症(rLDH)的风险因素。从成立到2022年6月23日,使用Ovid Medline、EMBASE、Cochrane图书馆和Web of Science数据库进行了系统的文献检索。纳入对初次手术后≥3个月经放射学证实的rLDH成年患者的观察研究,并使用预后质量研究(QUIPS)评估工具评估其质量。对单变量和多变量数据进行荟萃分析,并对显微椎间盘切除术后rLDH进行敏感性分析。纳入12项研究(n=4497,平均年龄:47.3;34.5%为女性),并对11项研究(n=4235)进行荟萃分析。平均随访38.4个月。平均复发率为13.1%,平均复发时间为24.1个月(范围:6-90个月)。临床上,年龄较大(OR:1.04,95%CI:1.00-1.08,n=1014)、糖尿病(OR:3.82,95%CI:1.58-9.26,n=2330)和吸烟(OR:1.80,95%CI:1.03-3.14,n=3425)增加了复发的可能性。放射学上,2型Modic改变(OR:7.93,95%CI:5.70-11.05,n=1706)和椎间盘突出(OR:12.23,95%CI:8.60-17.38,n=1707)增加了复发的可能性。证据不支持rLDH与性别之间的关联;BMI;职业劳动/驾驶;饮酒;Pfirmann分级,或疝出程度。老年患者、吸烟者、糖尿病患者、2型Modic改变或椎间盘突出的患者更有可能出现rLDH。需要对混杂因素进行更高质量的研究,以确定rLDH所有其他潜在风险因素的临床意义。
