Introduction

As a result of increased incidence of anterior cruciate ligament (ACL) injury in young athletes, there is a rise in the indications surgical ACL reconstruction procedures. The value of anterolateral ligament (ALL) reconstruction emerges as a proposed solution to prevent graft failures and improve stability in this high demanding category of patients. The purpose of this study is to present our experience with a novel hamstring auto-grafting technique, the single antegrade sling graft (SASG), for combined reconstruction of both ACL and ALL using autologous gracilis (GR) and semitendinosus (ST) grafts utilizing a single femoral tunnel and double tibial tunnels.

Materials and methods

From January 2020 to December 2021, 21 soccer players were operated utilizing the SASG technique, a modification of the technique of SANTI study group. Inclusion criteria were participating in pivoting sport, high-grade pivot shift examination (Grade 2–3), and evidence of a lateral femoral notch sign or Segond's fracture on preoperative imaging. Patients were assessed for 2 years postoperatively by Lachman’s test for anteroposterior laxity and pivot shift test for rotational laxity. The postoperative outcomes were assessed by Tegner-Lysholm and International knee documentation committee scores. Also, the postoperative complications such as stiffness, infection and graft failure were reported.

Results

21 male soccer players with a mean age 26.4 years were included in this study. After 2 years follow up there was a statistically significant improvement in the both post-operative functional scores, P value < 0.001. Fifteen patients (71.4%) could return to their preoperative sport activity level with no giving-way symptoms. Only one case of graft failure was reported in the follow up.

Conclusions

The single antegrade sling graft (SASG), for combined reconstruction of both ACL and ALL yielded good results in terms of stability and return to sports. The technique is reproducible, and results are comparable to the available published literature.

Purpose of the study

Rhizarthrosis—osteoarthritis of the thumb carpometacarpal (CMC) joint is usually a primary idiopathic disease. Total joint arthroplasty (TJA) is one of the surgical treatment options for symptomatic advanced thumb CMC arthritis. This retrospective study aims to evaluate the mid-term functional and radiological results of TJA with the minimum follow-up period of 3 years after the surgery.

Material and methods

Presented are the results of 136 total trapeziometacarpal joint replacements in the group of 105 patients consisted of 96 women and 9 men. Used prostheses were ELiS^® implant (27 cases), Ivory^® implant (42 cases), Touch^® Dual mobility (67 cases). The follow-up period was minimally 3 years postoperatively. In all the patients, along with range of motion and radiologic evaluation of implant position, the function and pain of operated joint were evaluated using DASH and VAS score at regular intervals pre- and postoperatively.

Results

At a mean of 85 months (range 38–126 months) post-operatively, patients in 116 cases (85%) reported full satisfaction and absence of symptoms and difficulties. In 12 cases (9%) some slight residual post-exercise pain was reported. In eight cases (6%) patients suffered from episodic rest-pain, but with a lower intensity than in the preoperative period. Postoperatively, the patients declared subjective improvement in hand function. The total DASH score and VAS score decreased in all patients, while ROM increased. The course of all of TJA surgeries was complication-free. Five patients needed revision surgery. In two patients a dislocation has occurred and in three cases a loosening of the cup’s implant was reported. The most frequent postoperative complication was the occurrence of transient paraesthesias of the thumb in eight cases (6%).

Conclusions

TJA is the method of choice in management of advanced symptomatic osteoarthritis of the thumb CMC joint. Mastering surgical technique, TJA represents safe and effective treatment method in advanced degenerative changes of the thumb CMC joint and it’s benefits exceed possible perioperative and postoperative risks.

Introduction

Total joint arthroplasties generally achieve good outcomes, but chronic pain and disability are a significant burden after these interventions. Acknowledging relevant risk factors can inform preventive strategies. This study aimed to identify chronic pain profiles 6 months after arthroplasty using the ICD-11 (International Classification of Diseases) classification and to find pre and postsurgical predictors of these profiles.

Materials and methods

Patients undergoing total knee/hip arthroplasty (n = 209, female = 54.5%) were assessed before surgery, 48 h and 6 months postsurgery for sociodemographic, pain-related, disability and psychological characteristics. K-means-constrained cluster analysis identified chronic pain profiles based on 6-month pain intensity, pain interference and disability. Chi-square tests or one-way ANOVA explored between-cluster differences. Multinomial regression identified predictors of cluster membership. Separate models analyzed presurgical (model 1), postsurgical (model 2) and a combination of previously significant pre and postsurgical (model 3) variables.

Results

A three-cluster solution was selected, translating increasingly worse chronic pain severity: cluster 1 (C1, n = 129), cluster 2 (C2, n = 60) and cluster 3 (C3, n = 20). There were presurgical differences among clusters in the presence of other painful sites (p = 0.013, ϕc = 0.20), pain interference (p = 0.038, η² = 0.031), disability (p = 0.020, η² = 0.037), pain catastrophizing (p = 0.019, η² = 0.060), anxiety (p < 0.001, η² = 0.087), depression (p = 0.017; η² = 0.039), self-efficacy (p = 0.018, η² = 0.038) and satisfaction with life (p = 0.034, η² = 0.032), postsurgical pain frequency (p = 0.003, ϕc = 0.243) and intensity (p < 0.001, η² = 0.101). In model 1, disability predicted C2 (OR = 1.040) and anxiety predicted C3 (OR = 1.154) membership. In model 2, pain intensity predicted C3 (OR = 1.690) membership. In model 3, presurgical anxiety predicted C3 (OR = 1.181) and postsurgical pain intensity predicted C2 (OR = 1.234) and C3 (OR = 1.679) membership.

Conclusions

Most patients had low chronic pain severity at 6 months, but a relevant percentage exhibited poor outcomes. Membership to different outcome profiles was predicted by presurgical anxiety and acute postsurgical pain. These seem promising targets to prevent pain chronification that should be optimized for better surgical outcomes.

Introduction

The combined effect of diabetes mellitus and obesity (Diabesity) on total knee replacement (TKR) outcomes is unclear. This study aimed to assess whether diabesity influenced functional outcomes and complication rate following primary TKR.

Materials and methods

This case-controlled study compared the independent effects of obesity, diabetes, and diabesity on TKR outcomes. Data were collected pre-operatively and 12 months post-operatively from a single study centre. Outcomes included Oxford Knee Score (OKS), EuroQol 5-dimensions (Eq. 5D), post-operative satisfaction and complication rate.

Results

There were 2577 TKRs in the cohort, of which 244 (9.5%) had diabesity. Diabesity was independently associated with reduced pre-operative OKS (-1.14 points, 95% CI -1.97 to -0.31, p = 0.007) and OKS improvement (-2.37 points, 95% CI -3.11 to -1.62, p < 0.001). Obesity was also independently associated with worse pre-operative OKS (-0.78 points, 95% CI -1.28 to -0.27, p = 0.003) and OKS improvement (-0.81 points, 95% CI -1.26 to -0.35, p = 0.001). Both diabesity (-0.05 points, 95% CI -0.08 to -0.02, p = 0.003) and obesity (-0.02 points, 95% CI -0.04 to 0.00, p = 0.039) were associated with worse pre-operative Eq. 5D score. Patients with diabesity reported reduced post-operative satisfaction due to obesity independently (OR 0.75, 95% CI 0.56 to 1.00, p = 0.048). Diabesity was not independently associated with post-operative complications.

Conclusions

Diabesity was independently associated with a worse knee-specific function and Eq. 5D score pre-operatively, and diminished joint specific functional improvement following TKR. Patients with diabesity also experienced reduced post-operative satisfaction due to obesity independently.

Patients with unstable hemodynamics and unstable pelvic ring injuries are still demanding patients regarding initial treatment and survival. Several concepts were reported during the last 30 years. Mechanical stabilization of the pelvis together with hemorrhage control offer the best treatment option in these patients. While pelvic ring stabilization using pelvic binders, external fixators and the pelvic C-clamp are the basis for mechanical stability of the pelvic ring, the optimal modality for pelvic bleeding control is still under discussion. Beside angioembolization (AE) and Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA), pelvic packing PP (predominantly extraperitoneal) with direct access to the pelvic bleeding sources, are potential options. The present overview represents the present status, results and the value of pelvic packing in treating these patients. Interpretation of these results must consider the difference between the initial European concept of pelvic ring stabilization followed by PP in contrast to the North American concept with a reduced rate of pelvic ring stabilizations.

Introduction

There is a lack of clinical evidence supporting the decision-making process between high tibial osteotomy (HTO) and unicomparmental knee arthroplasty (UKA) in gray zone indication, such as moderate medial osteoarthritis with moderate varus alignment. This study compared the outcomes between HTO and UKA in such cases and assessed the risk factor for not maintaining clinical improvements.

Materials and methods

We retrospectively reviewed 65 opening-wedge HTOs and 55 UKAs with moderate medial osteoarthritis (Kellgren-Lawrence grade ≥ 3 and Ahlback grade < 3) and moderate varus alignment (5°< Hip-Knee-Ankle angle < 10°) over 3 years follow-up. Confounding factors including patient demographics, postoperative lower limb alignment was assessed. Dummy variable was used to categorize the HTO and UKA according to presence of tibia varus deformity (medial proximal tibial angle of 85°). Clinical outcomes were measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score preoperatively, 1 year postoperatively, and at the last follow-up. Cox regression analysis identified risk factors for not achieving minimal clinically important differences (MCID) in WOMAC scores.

Results

The WOMAC score at 1-postoperative year significantly improved beyond MCID in all UKA and HTO. However, over a mean follow-up of 68.7 months (HTO) and 64.3 months (UKA), 16 patients (13.3%) experienced clinical deterioration. Notably, patients with suboptimal postoperative alignment, those undergoing HTO without tibial vara, and UKA with tibial vara had higher risks of clinical deterioration during the mid-term period.

Conclusion

Tibial varus deformity differentially affects clinical outcomes after HTO and UKA in moderate medial compartment osteoarthritis with moderate varus alignment. Clinicians should consider the deformity’s origin when selecting treatment for this patient, as certain combinations (HTO without tibia vara and UKA with tibia vara) are associated with increased risk of not maintaining mid-term clinical improvements.

Introduction

Liquid biopsy as a non-invasive method to investigate cancer biology and monitor residual disease has gained significance in clinical practice over the years. Whilst its applicability in carcinomas is well established, the low incidence and heterogeneity of bone and soft tissue sarcomas explains the less well-established knowledge considering liquid biopsy in these highly malignant mesenchymal neoplasms.

Materials and methods

A systematic literature review adhering to the PRISMA guidelines initially identified 920 studies, of whom 68 original articles could be finally included, all dealing with clinical applicability of liquid biopsy in sarcoma. Studies were discussed within two main chapters, i.e. translocation-associated and complex-karyotype sarcomas.

Results

Overall, data on clinical applicability of liquid biopsy in 2636 patients with > 10 different entities of bone and soft tissue sarcomas could be summarised. The five most frequent tumour entities included osteosarcoma (n = 602), Ewing sarcoma (n = 384), gastrointestinal stromal tumour (GIST; n = 203), rhabdomyosarcoma (n = 193), and leiomyosarcoma (n = 145). Of 11 liquid biopsy analytes, largest evidence was present for ctDNA and cfDNA, investigated in 26 and 18 studies, respectively.

Conclusions

This systematic literature review provides an extensive up-to-date overview about the current and potential future uses of different liquid biopsy modalities as diagnostic, prognostic, and disease monitoring markers in sarcoma.

Introduction

Ankle fractures represent a significant portion of orthopedic injuries, with fracture dislocations tending to have worse outcomes. Logsplitter fractures represent a subset of fracture dislocations in which the talus is axially wedged in the tibiofibular joint. We aim to comprehensively investigate and report on the complications and functional outcomes associated with ankle fracture-dislocations.

Materials and Methods

Following PRISMA guidelines, a medical librarian conducted a literature search in Embase, Ovid Medline, Scopus, Cochrane Central Register of Controlled Trials, and The Cochrane Database of Systematic Reviews. Studies examining ankle fracture-dislocations and reporting on functional or employment outcomes were included. Excluded were non-English studies, abstracts, conference proceedings, letters, perspective pieces, reviews, editorials, and case reports or series with fewer than five patients. Data on functional outcomes were extracted and reported using descriptive statistics. A comparative analysis of AOFAS scores between Logsplitter and ankle fracture-dislocations was conducted using pooled means and independent t-tests.

Results

A total of 21 studies involving 810 cases of ankle fracture-dislocations were included. The pooled mean AOFAS score across 13 studies was 81.5, indicating “good” outcomes, while Logsplitter injuries had a significantly lower mean score of 75.8 compared to 82.9 for other ankle fracture-dislocations (p = 0.016). Complications included wound infection (7.3%), posttraumatic osteoarthritis (29.2%), nonunion/malunion (12.6%), and malunion. No studies reported on employment outcomes.

Conclusions

Ankle fracture-dislocations are high-energy injuries that affect a younger population compared to non-dislocated ankle fractures. Their functional outcomes resemble those of pilon fractures more than common ankle fractures. Logsplitter injuries are a subset of fracture dislocations that occur in even younger patients, with worse functional outcomes. This information can guide perioperative discussion and expectations for functional recovery. Additional studies are needed to evaluate the impact of these injuries on return to employment.

Background

In the case of end-stage hallux rigidus, first metatarsophalangeal (MTP) joint arthrodesis is the gold-standard and is traditionally performed via an open approach. However, complications such as nonunion have been reported to be as high as 30%. Recently, there have been reports demonstrating a percutaneous approach to be effective and safe.

Methods

Forty-nine patients with end-stage hallux rigidus underwent percutaneous first MTP joint arthrodesis with calcaneus autograft performed by a single surgeon. Each patient underwent a minimum of 24 month clinical and radiographic follow up, including 3 month post operative computed tomography scans. Clinical outcomes were assessed using the Visual Analog Scale (VAS) and Foot Function Index (FFI) preoperatively and at final follow-up.

Results

Mean follow-up was 27.3 months. Bone union was observed in 46 patients (93.9%). Mean time to union was 3.1 months. Nonunion rate was 6.1%. Overall complication rate was 12.2%. Mean pre- and postoperative VAS scores were 7.5 and 0.2, respectively (P < .0001). Mean pre- and postoperative total FFI values were 56.3 and 15.7 (P < .0001), respectively. Patient satisfaction after the procedure was 93.9%.

Conclusion

Observed union rate is comparable to the average fusion rate previously reported for open and minimally invasive procedure union rates. Mean time to union was observed to be comparable to open procedures union time. Observed overall complication rate is similar to those reported for open techniques as well. Patient reported outcomes demonstrated a significant reduction in postoperative VAS and FFI for the percutaneous metatarsophalangeal arthrodesis with calcaneus bone autograft. Patient satisfaction rates compared favorably to those reported following open surgery.

Iliosacral screw osteosynthesis is a widely recognized technique for stabilizing unstable posterior pelvic ring injuries, offering notable advantages, including enhanced mechanical stability, minimal invasiveness, reduced blood loss, and lower infection rates. However, the procedure presents technical challenges due to the complex anatomy of the sacrum and the proximity of critical neurovascular structures. While conventional fluoroscopy remains the primary method for intraoperative guidance, precise preoperative planning using multiplanar reconstructions and three-dimensional volume rendering is crucial for ensuring accurate placement of iliosacral or transsacral screws. Particular attention must be given to the preoperative evaluation of both the iliosacral and transsacral corridors, as anatomical variations may restrict the available space for screw insertion. This review aims to highlight the essential aspects of sacroiliac osteosynthesis, with a focus on the critical role of thorough preoperative planning and its impact on achieving successful surgical outcomes.
