Randomized Controlled Trial
The accuracy of subacromial injections: a prospective randomized magnetic resonance imaging study.
To assess the accuracy of shoulder infiltrations in the subacromial bursa (SAB) by a posterior or an anteromedial approach. Magnetic resonance imaging (MRI) and clinical outcome were used for evaluation. ⋯ Level II.
-
To prospectively assess clinical outcomes and regeneration of osteoarthritic cartilage lesions treated with an articular cartilage paste grafting technique. ⋯ Level IV, case series.

Comparative Study
Shoulder instability and related rotator cuff tears: arthroscopic findings and treatment in patients aged 40 to 60 years.
To report our experience with the arthroscopic treatment of patients aged 40 to 60 years with rotator cuff lesions, shoulder instability, or both, and to seek a relationship among capsular-labral complex lesions, cuff tears, number of dislocations, and patient age. ⋯ Level IV, case series.

Comparative Study
Comparison of tibial inlay versus transtibial techniques for isolated posterior cruciate ligament reconstruction: minimum 2-year follow-up.
Surgical treatment of isolated posterior cruciate ligament (PCL) injuries is controversial. The purpose of this retrospective study was to evaluate the surgical outcomes of PCL reconstruction. Two techniques were compared, the traditional endoscopic and the more recent tibial inlay, to determine if the inlay technique yielded more stable reconstructions. ⋯ The results of this study indicate that neither method (transtibial or inlay) of PCL reconstruction consistently restores anteroposterior stability to its original state when using a single-bundle femoral attachment site.

Two different operative techniques for stabilizing the patella against lateral displacement movement were investigated. ⋯ In cadaver specimens, we evaluated the effect of tibial tubercle transfer and the patellofemoral ligament and found that reconstruction of the patellofemoral ligament alone was sufficient to restore stability in a cadaveric model. Additionally, we found that the flexion angle had little effect on the loading of the medial patellofemoral ligament autograft, which would support early mobilization of patients after surgery. We found that the graft was not unduly loaded.
