There are several reported causes of midbody extrusion after lateral meniscal allograft transplantation. However, there are no reports studying the correlation between the position of the bony bridge and extrusion of the midbody after meniscal allograft transplantation. ⋯ The more closely the center of the bony bridge approached 50% of the entire tibial plateau, the less extrusion of the midbody occurred. Anatomic placement of the bony bridge of lateral meniscal allograft is imperative to prevent extrusion after lateral meniscal allograft transplantation.

Arthroscopic Bankart repair emerged in the 1990s as a minimally invasive alternative to open repair. The optimal technique of surgical stabilization of the unstable glenohumeral joint remains controversial. ⋯ Review of the ABOS data shows a trend toward arthroscopic shoulder stabilization over time, with the use of open repair declining. Reported complications were lower overall in the arthroscopic stabilization group when compared with open surgeries.

The effect of lace-up ankle braces on injury rates in high school basketball players.
Ankle injuries are the most common injury in basketball players. However, no prospective studies have been performed to determine if wearing lace-up ankle braces will reduce the incidence of ankle injuries in high school athletes. ⋯ Use of lace-up ankle braces reduced the incidence but not the severity of acute ankle injuries in male and female high school basketball athletes both with and without a previous history of an ankle injury.

Comparative Study
Gender-based differences in outcome after anatomic double-bundle anterior cruciate ligament reconstruction with hamstring tendon autografts.
Although previous studies suggested that female patients are predisposed to increase graft laxity compared with male patients after single-bundle anterior cruciate ligament reconstruction using autogenous hamstring tendons, there have been no studies specifically examining gender-based differences in outcome after anatomic double-bundle anterior cruciate ligament reconstruction with hamstring tendon autografts. ⋯ The results of assessment for ligament laxity at the 2-year postoperative evaluation in the female group were approximately identical to those of the male group after anatomic double-bundle anterior cruciate ligament reconstruction using autogenous hamstring tendons. Therefore, the present study suggests that anatomic double-bundle anterior cruciate ligament reconstruction using autogenous hamstring tendons provides satisfactory knee stability to female patients as well as male patients.

Fractures of the proximal fifth metatarsal metaphysis (ie, the Jones fracture) can be problematic in the elite athlete because of a high incidence of nonunion and refracture with nonoperative treatment. Although these fractures are not common, athletes can suffer refracture or nonunion of a Jones fracture despite operative stabilization. This is often attributable to hardware of insufficient strength, aggressive postoperative rehabilitation, or biologic insufficiency at the fracture site. ⋯ The authors recommend revision fixation with a large, solid screw (5.5 mm or larger) and autologous bone grafting for symptomatic refractures and nonunions of the proximal fifth metatarsal in elite athletes. Additional investigation is needed to determine whether BMA combined with DBM is an effective substitute for cancellous autograft.
