Comparative Study
Does posterior tibial slope influence knee functionality in the anterior cruciate ligament-deficient and anterior cruciate ligament-reconstructed knee?
The purpose of this study was to investigate the relation between knee functionality and posterior tibial slope in anterior cruciate ligament (ACL)-deficient and ACL-reconstructed patients. ⋯ Level IV, therapeutic case series.

Comparative Study
Comparative analysis of single-row versus double-row repair of rotator cuff tears.
Our goal in this analysis was to compare clinical outcomes and radiographic healing rates of double-row (DR) transosseous-equivalent versus single-row (SR) Mason-Allen configuration (MAC) arthroscopic repair techniques. ⋯ Level III, retrospective comparative study.

Percutaneous screw fixation of the anterior column of the acetabulum has been a challenging task because of its unique anatomy and a risk of intra-articular penetration. Evidence is lacking for any tools to provide visual scrutiny of fracture reduction and intra-articular screw penetration. We report 2 cases of fracture of the acetabulum that developed in young female athletes, in which the anterior column was fixed with a percutaneous screw by use of hip arthroscopy as an assisting tool for intra-articular observation. In our experience this method was found to be promising in terms of anatomic reduction of the fracture site, avoiding articular penetration during screw insertion, with additional advantages of joint debridement, lavage, and reduction in radiation exposure.

The purpose of this study was to assess whether it was possible to harvest plugs from the posterior femoral condyles with a standard mosaicplasty instrumentation through retroligamentous approaches and whether the plugs harvested from the posterior condyles presented the same characteristics as those harvested from the standard donor sites regarding the length, cartilage thickness, and cartilage angle. ⋯ The posterior condyles cannot be proposed as a donor site for osteochondral autograft with a mosaicplasty instrumentation because it is difficult to obtain plugs with a perpendicular cartilage surface from this localization.
