Randomized Controlled Trial Comparative Study
Prospective randomized clinical trial of single- versus double-row suture anchor repair in 2- to 4-cm rotator cuff tears: clinical and magnetic resonance imaging results.
The purpose of this study was to compare the clinical outcomes and the retear rates of arthroscopic single-row (SR) and double-row (DR) suture anchor repair in 2- to 4-cm rotator cuff tears. ⋯ Level I, randomized controlled trial.

Comparative Study
Medial meniscus root tear refixation: comparison of clinical, radiologic, and arthroscopic findings with medial meniscectomy.
To investigate the clinical, radiologic, and arthroscopic findings of pullout repair in medial meniscus root tear (MRT) and to compare the results of pullout repair and partial meniscectomy. ⋯ Level III, retrospective comparative study.

Acute acromioclavicular joint dislocations (ACDs) may be treated arthroscopically with flip buttons. This extra-articular fixation is easy to implant and is well tolerated. Between 2007 and 2009, 20 ACD patients (2 women and 18 men; mean age, 32 years) had surgery by the arthroscopic TightRope technique (Arthrex, Naples, FL). ⋯ We describe 4 cases with loss of reduction due to rupture of the sutures running across the buttons: 2 women with joint hyperlaxity and acute Rockwood grade IV ACD and 2 men, heavy manual workers, with joint hyperlaxity and acute Rockwood grade IV ACD. The use of flip buttons might not be indicated in patients with joint hyperlaxity because they are able to obtain immediate stability only on the vertical plane and not on the horizontal plane. Anteroposterior movements of the acromioclavicular joint might rub the suture against the bone tunnels leading to wear and cutting.

Review Historical Article
Adoption of new technology in sports medicine: case studies of the Gore-Tex prosthetic ligament and of thermal capsulorrhaphy.
Evaluation of new technology in sports medicine is supposed to promote improvements in the care of patients. It is also supposed to prohibit technology that can harm patients. This evaluation process is not perfect and at times can promote technology that not only does not help patients but may harm them. ⋯ Gore & Associates, Flagstaff, AZ) for patients with anterior cruciate ligament deficiency. On analysis of the quick adoption of these 2 failed procedures, certain recommendations are apparent for improvement of the evaluation process. There must be a sound rationale behind any new technology, basic science research into the theory of the medical technology, and demonstrated improvements in animal models and clinical studies that are prospective cohort studies or randomized controlled trials, and finally, there must be careful follow-up and postmarket surveillance.
