Hamstrings anterior cruciate ligament reconstruction with and without platelet rich fibrin matrix.

Purpose: Anterior cruciate ligament (ACL) rupture is the most common complete ligamentous injury in the knee. Many studies explored ACL graft integration and maturation, but only a few assessed the application of platelet rich fibrin matrix (PRFM) as augmentation for ACL reconstruction. The main aim of this study was to test the PRFM augmentation in terms of graft-bone integration and knee stability.

Shoulder hemiarthroplasty for fractures of the proximal humerus.

Proximal humeral fractures were managed with primary hemiarthroplasty in 57 patients, 53 women (93%) and 4 men (7%) aged 51-87 years (mean 72.2). The mean follow-up period was 52 months (range 12-98), and the mean Constant score was 59.

Platelet-rich plasma augmentation for arthroscopic rotator cuff repair: a randomized controlled trial.

Background: After reinsertion on the humerus, the rotator cuff has limited ability to heal. Growth factor augmentation has been proposed to enhance healing in such procedure.

Purpose: This study was conducted to assess the efficacy and safety of growth factor augmentation during rotator cuff repair.

Transtendon arthroscopic repair of partial-thickness, articular surface tears of the supraspinatus: results at 2 years.

Partial-thickness articular tears of the supraspinatus represent a not uncommon event in shoulder pathology, but their treatment remains controversial. We believe that these lesions must be treated with surgical repair: we hereby describe our technique of transtendon arthroscopic repair. We have treated 33 patients with an average age of 53.

Cost-effectiveness of cemented versus cementless total hip arthroplasty. A Markov decision analysis based on implant cost.

Background: Probabilistic decision analysis is a means of reflecting the uncertainty parameter in models and of presenting it in a comprehensible manner to decision-makers.

Materials And Methods: A cost-effectiveness model was constructed to compare the cementless and cemented total hip prostheses implanted at our department in terms of lifetime costs and quality-adjusted life-years (QALY). Revision rates were obtained from the Orthopaedic Prosthesis Register of the Laboratory of Medical Technology, Istituti Ortopedici Rizzoli, Bologna, Italy.
