Patellofemoral instability is a well-recognized problem, but there are currently no published patient-reported quality of life outcome measures that are disease specific for the treatment of this population. ⋯ The BPII demonstrates content validity, strong initial reliability, and a statistically significant level of construct validity in patients with patellofemoral instability. This population includes patients with recurrent patellofemoral instability as well as surgically stabilized patients.

Sex-specific outcomes have been reported in anterior cruciate ligament reconstruction as well as in osteoarthrosis progression, but there are currently no related published data on autologous chondrocyte implantation (ACI). The present prospective study was performed to investigate sex-dependent differences in the results after ACI. ⋯ Autologous chondrocyte implantation is a promising treatment option for full-thickness cartilage defects of male and female knee joints. Female patients with patellar defects have worse prognostic factors.

Acromioclavicular (AC) joint separation is a common injury, usually affecting young adults. Controversy exists regarding whether to excise the distal clavicle when surgical intervention is required. ⋯ The study suggests that excision of the distal clavicle in this procedure is not associated with increased anterior-posterior or superior-inferior instability in this model.

Tibial eminence fractures occur most commonly in skeletally immature children. Several techniques using physeal-sparing fracture fixation have been described, but their structural properties have not been evaluated. ⋯ Suture anchors provide inconsistent fixation for tibial eminence fractures.

Recently, bony defects of the glenoid in patients with traumatic anterior shoulder instability have been increasingly noticed. The bone fragment of a bony Bankart lesion is often utilized for Bankart repair, but the fragment is at times smaller than the glenoid defect. The reason for this mismatch in size is unknown. ⋯ Bone fragment absorption was seen in all of the shoulders with bony Bankart lesions. Most bone fragments showed severe absorption within 1 year after the primary traumatic episode. Before arthroscopic Bankart repair, not only glenoid defects but also bone fragment absorption should be assessed.
