Distal femoral osteotomy (DFO) improves valgus limb alignment. However, it might affect lower limb length discrepancy (LLD) and influence functional scores. This study aims to evaluate functional scores and radiographic parameters associated with LLD after DFO.

The medial collateral ligament (MCL) and lateral collateral ligament (LCL) are paramount for joint stability. Their elongation patterns may change during fixed-bearing and mobile-bearing unicompartmental knee arthroplasty (FB and MB UKA). This study aims to explore the relationship between the elongation of MCL, LCL, and changes in joint space, as well as their correlation with functional scale scores during FB and MB UKA.

Osteoarticular infections (OAI) after prosthetic surgery have serious functional and economic consequences. Rapid tests for alpha-defensin (TAD) and leukocyte esterase (TLE) are two intra-articular markers involved in the diagnosis of OAIs. TLE cannot be applied in the presence of blood unless centrifugation is used, but the rate of "non-application" of the test for this reason is unknown in complex microbiological situations (discordant or negative puncture, ongoing antibiotic treatment). We therefore conducted a prospective study to determine: 1) the performance of the TAD and TLE rapid tests in diagnosing complex OAI, 2) the rate of non-application of the TLE due to hemarthrosis, and 3) the concordance between the two tests.

Quantitative Gait Analysis (QGA) is the gold-standard for detailed study of lower-limb movement, angles and forces, especially in pediatrics, providing a decision aid for treatment and for assessment of results. However, widespread use of QGA is hindered by the need for specific equipment and trained personnel and high costs. Recently, the OpenPose system used algorithms for 2D video movement analysis, to determine joint points and angles without any supplementary equipment or great expertise. The present study therefore aimed to validate application of OpenPose for gait analysis in children with locomotor pathology, thereby circumventing the limitations of QGA.

Dupuytren's disease is a benign disorder leading to flexion contracture of the fingers and functional disability. Many treatments have been described. Open fasciectomy is the gold standard; however percutaneous needle fasciotomy (PNF) is a reliable option for uncomplicated primary contracture but it has a high rate of recurrence.

Ruptures of the quadriceps tendon (QT) are rare but serious injuries accounting for less than 2% of all tendon injuries around the knee. These injuries, often occurring in individuals over 40, are leading to a loss of active extension and a significant impact on knee function. While the treatment of acute QT ruptures through various reinsertion techniques has shown excellent outcomes, managing chronic injuries and failed primary repairs remains challenging due to tendon retraction and difficulties in repositioning the tendon stump. This study introduces a novel approach associating direct tendon reinsertion with metal frame reinforcement, aiming to effectively lower the retracted tendon to the proximal pole of the patella. This technique offers a promising alternative that addresses the limitations of traditional methods and potentially improves patient outcomes by providing a safe primary fixation and protection of the repair, enabling early rehabilitation and reducing the need for subsequent interventions. LEVEL OF EVIDENCE: IV; case series study.

The management of antiplatelet therapy (APT) in patients undergoing spinal surgery is complex, requiring balancing the risks of thromboembolic events against those of potential perioperative bleeding. This review evaluates the effects of continuing versus discontinuing APT on the surgical outcomes of spinal surgery.

A subset of patients undergoing anatomic and reverse total shoulder arthroplasty (aTSA and rTSA) lag behind their peers in regaining overhead range of motion (ROM) after surgery. The primary purpose of this study was to compare the rate of recovery of ROM after aTSA and rTSA performed in stiff (preoperative passive external rotation [ER] ≤0 °) versus non-stiff (preoperative passive ER >0°) shoulders with RCI-GHOA.

Although virtual reality (VR) simulators have demonstrated their efficiency for basic technical skill training of healthcare professionals, validation for more complex and sequential procedures, especially in arthroscopic surgery, is still warranted. We hypothesized that the VR-based training simulation improves arthroscopic cuff repair skills when transferred to realistic visual and haptic conditions.

Subtalar arthrodesis (SA) is a common procedure to treat end-stage subtalar osteoarthritis. We set out in order to determine whether a combined direct fixation of both anterior and posterior facets during SA might influence union and complications compared to isolated fixation of the posterior facet. Our hypothesis was that a combined fixation increases the union rate and reduces the complication rate.

Removal of hardware (HR) following a fracture is a frequent question from patients. The incidence of this kind of intervention remains very variable depending on the healthcare systems and its interest is debated in view of the benefits and associated risks that remain poorly defined. Mandatory preoperative information cannot be given optimally in this context.

Acetabular fractures account for 7% of osteoporotic fractures, with an epidemiological peak between 75 and 80 years of age. The aim of this study is to evaluate the results of treatment of these fractures in a population aged over 65.

Tibial condylar valgus osteotomy (TCVO), or Chiba osteotomy, is a recognized procedure for treating advanced knee osteoarthritis in middle-aged individuals. Although its effectiveness is established, limited literature exists on its outcomes for specific conditions such as post-traumatic deformities, Blount disease (BD), and Pagoda-like proximal tibia varus deformities.

The GeneXpert® MRSA/SA SSTI test allows early detection of methicillin-resistant staphylococci in intraoperative samples of prosthetic joint infections (PJI) in order to stop early broad-spectrum antibiotics.

The literature agrees that an increased posterior tibial slope (PTS) increases the risk of anterior cruciate ligament (ACL) rupture in adults. However, there is no consensus on the average normal value and it varies with growth. We carried out a systematic review of the literature to answer 4 questions faced with an increase in PTS in children: METHOD: We conducted a systematic review of the literature in accordance with PRISMA criteria. The inclusion criteria were all studies analyzing the association between increased PTS and the occurrence of knee disease in patients, the majority of whom were under 18 years of age or had immature skeletons. For each study, we recorded the demographic characteristics of the patients, the type of measurements performed, the PTS values and the association between the PTS value and the occurrence of pathology.

Computer-assisted or robot-assisted surgery in theory enables optimal positioning in total knee arthroplasty (TKA). The aim of the present study was to evaluate the rotational positioning of the femoral TKA implant using the ROSA Knee® robotic system. The hypothesis was that the accuracy of the rotation obtained by the ROSA Knee® robotic arm was comparable to that obtained by navigation.
