"Double-Row Rip-Stop" Technique for Arthroscopic Rotator Cuff Repair.

Rotator cuff repair depends on both the fixation strength of the chosen repair construct and the local healing response of the repaired tissue. Among a growing discussion surrounding the superiority of one surgical technique over another, the surgeon's ability to complete a rotator cuff repair with technical acuity in a timely manner remains paramount. Double-row repairs as well as rip-stop configurations have been proposed to limit failures found after arthroscopic rotator cuff repairs.

Effects of hip joint transverse plane range of motion with a modeled effusion and capsular tear: A cadaveric study.

Background: Multiple factors contribute to range of motion of the hip joint in the transverse plane: bony anatomy, hip capsule, corresponding ligaments, articular labrum, ligamentum teres, and negative intra-articular pressure. We hypothesized that violation of the negative pressure of the hip and simulation of an effusion would increase range of motion in the transverse plane in a cadaver model.

Methods: Ten hip specimens were obtained and dissected with the femur and iliac wing mounted in a custom joint-testing rig in neutral position.
