Effectiveness over time of the reverse shoulder prosthesis for acute proximal humeral fracture.

Background: Reverse total shoulder arthroplasty (rTSA) has proven to be an effective surgical procedure for irreparable rotator cuff tears, comminuted fractures of the proximal humerus, and shoulder arthroplasty revision surgeries. We know from the literature that the functional results are good in the short term, but not whether these results remain stable in the long term or, on the contrary, show deterioration in functionality.

Objective: This study aims to analyze the functionality, degree of satisfaction, complications, and prosthesis survival at different cut-off points in patients with complex proximal humerus fractures treated with rTSA, with a minimum postoperative follow-up of 7 years.

The method of femoral tunnel drilling in anterior cruciate ligament reconstruction does not influence the return to sport rate.

Background: Limited evidence is available comparing the modified transtibial (MTT) and transportal (TP) techniques in anterior cruciate ligament (ACL) reconstruction and their impact on returning to sports participation. The objective was to analyze the outcomes after arthroscopic reconstruction of the ACL in recreational athletes with a 2-year postoperative follow-up, comparing the MTT and TP techniques, based on the method used to drill the femoral tunnel.

Hypotesis: The rate of return to sport would be comparable regardless of the surgical technique used.

Smoking is not closely related to revision for periprosthetic joint infection after primary total knee and hip arthroplasty.

Background: The influence of smoking on the risk of periprosthetic joint infection (PJI) remains unclear. The objective was to explore the impact of smoking on PJI after primary total knee (TKA) and hip (THA) arthroplasty.

Hypothesis: Current smoking patients should have an increased risk of PIJ compared with nonsmoking patients.
