ACL reconstruction using a quadruple semitendinosus graft with cortical fixations gives suitable isokinetic and clinical outcomes after 2 years.

Purpose: The objective of this single-center randomized single-blinded trial was to assess the hypothesis that anterior cruciate ligament reconstruction (ACLR) using a four-strand semitendinosus (ST) graft with adjustable femoral and tibial cortical fixation produced good outcomes compared to an ST/gracilis (ST/G) graft with femoral pin transfixation and tibial bioscrew fixation. Follow-up was 2 years.

Methods: Patients older than 16 years who underwent primary isolated ACLR included for 1 year until August 2017 were eligible.

Acromial insufficiency in reverse shoulder arthroplasties.

Hypothesis: Reverse shoulder prostheses depend on deltoid function. An injury to the acromion, either fracture or meso-acromion, or deltoid injury, may affect the outcomes of patients after receiving a reverse shoulder prosthesis.

Methods: Four-hundred and fifty-seven consecutive reverse shoulder prostheses were implanted between January 1992 and June 2003 by one of seven surgeons in five separate centers.
