The purpose of this study was to assess the functional results of arthroscopic repair of massive rotator cuff tears in patients who had stage 3 and 4 fatty degeneration of the rotator cuff musculature, according to the Goutallier scale. ⋯ Level IV, therapeutic case series.

Comparative Study
Patient perceptions of open and arthroscopic shoulder surgery.
There has been a significant increase in surgeon as well as patient interest in arthroscopic treatment of shoulder pathology. We hypothesize that patients have a strong preference for arthroscopic shoulder surgery. Currently, there are no data in the literature reporting on how people perceive open versus arthroscopic shoulder surgery. ⋯ Shoulder surgeons should be aware of these perceptions when discussing treatment options with patients. A continued effort should be made to emphasize known scientific data when considering the relative risks and benefits of arthroscopic and open shoulder surgery.

Comparative Study
Cyclic load testing of biodegradable suture anchors containing 2 high-strength sutures.
The purpose of this study was to test 4 different biodegradable suture anchors threaded with 2 high-strength sutures under cyclic loading conditions in humeral cadaveric specimens divided into 2 different age groups. ⋯ Rotator cuff anchors perform differently in younger humeral bone than in older humeral bone. Most displacement with cyclic loading occurring between the anchor and bone takes place in the first 100 cycles. Anchors in older bones can be expected to fail at lower loads.

A clinical trial was carried out to investigate the long-term outcome of Meniscus Arrow (Bionx Implants, Blue Bell, PA) repair. ⋯ Level IV, therapeutic case series.

We prospectively assessed 22 consecutively treated patients to determine the effectiveness and safety of arthroscopically assisted posterior cruciate ligament (PCL) reconstruction by using a quadriceps tendon autograft. ⋯ Level IV, therapeutic study.
