Randomized Controlled TrialComparison of cementless twin-peg, cemented twin-peg and cemented single-peg femoral component migration after medial unicompartmental knee replacement: a 5-year randomized RSA study.
The component design and fixation method of joint arthroplasty may affect component migration and survival. The aim of this study was to compare fixation of cementless twin-peg (CLTP), cemented twin-peg (CTP) and cemented single-peg (CSP) femoral components of medial unicompartmental knee replacement (UKR). ⋯ At 5-year follow-up, fixation of UKA femoral components with twin-peg was not superior to the single-peg design. Cementless and cemented twin-peg femoral components had similar fixation. A lower flexion angle was correlated with higher component migration.

Novel morphogenic knee implant delivers comparable mid-term outcomes as compared to conventional non-morphogenic implants.
Conventional total knee arthroplasty (C-TKA) implants have well-established mid- and long-term outcomes. The novel TKA (N-TKA) implants provide morphogenic implant components with smaller size increments to facilitate anatomical replication. The aim of the study is to evaluate if these advantages provides better clinical outcomes. ⋯ lll.

Accuracy comparison of cup positioning during total hip arthroplasty using Hip Align and AR-Hip in the supine position.
The aim of this study is to compare the accuracy of acetabular cup positioning between the accelerometer-based navigation system and the augmented reality-based navigation system during THA in the supine position. ⋯ The accuracy of the acetabular cup positioning between the Hip Align and AR-Hip showed no difference during THA in the spine position. The high BMI could have negative influence on the accuracy of cup positioning in THA using Hip Align, thus AR-Hip could be designable for obesity patients.

Review Case ReportsOne-stage anterior cruciate ligament revision surgery after primary failed double-bundle reconstruction: a systematic review.
Anterior cruciate ligament (ACL) revision surgery after failed double-bundle (DB) reconstruction is a challenging procedure. This study aimed to systematically review the research on ACL revision surgery following failed DB reconstruction, providing an overview on indications, surgical techniques, clinical outcomes and potential pitfalls occurring while performing this therapeutic approach. ⋯ One-stage ACL revision surgery following DB ACL reconstruction appears feasible providing satisfying outcomes and limited complications. The literature on this subject is limited and further comparative studies reporting long-term outcomes are needed, as high-level studies on this topic are still lacking.

Randomized Controlled TrialComparison of percutaneous compression plate to parallel screws in the treatment of nondisplaced femoral neck fractures in elderly patients: a prospective, randomized study.
The optimal internal fixation for non-displaced femoral neck fractures remains controversial. This study aimed to compare the clinical results of the percutaneous compression plate (PCCP) with parallel screws (PS) in treating femoral neck fractures in elderly patients. ⋯ The present study suggests that the PCCP is superior to the parallel screws fixation in the treatment of non-displaced elderly femoral neck fractures in terms of earlier full weight-bearing, shorter fracture healing time, and lower implant failure rate. Therefore, it may be a better therapeutic strategy for non-displaced femoral neck fractures in elderly patients.
