Randomized Controlled Trial
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.

Prevalence of Jumper's knee among nonelite athletes from different sports: a cross-sectional survey.
The prevalence of jumper's knee among nonelite athletes from different sports is unknown. ⋯ Prevalence of jumper's knee is high among nonelite athletes and varies between 14.4% and 2.5% for different sports. Jumper's knee is almost twice as common among male nonelite athletes compared with female athletes. Different sport-specific loading characteristics of the knee extensor apparatus, a younger age, a taller body stature, and higher body weight seem to be risk factors associated with patellar tendinopathy.

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.

The anterior cruciate ligament has been and is of great interest to scientists and orthopaedic surgeons worldwide. Anterior cruciate ligament reconstruction was initially performed using an open approach. When the approach changed from open to arthroscopic reconstruction, a 2- and, later, 1-incision technique was applied. ⋯ To evaluate the potential benefits of reconstructing the anterior cruciate ligament in an anatomic fashion, accurate, precise, and reliable outcome measures are needed. These include, for example, T2 magnetic resonance imaging mapping of cartilage and quantification of graft healing on magnetic resonance imaging. Furthermore, there is a need for a consensus on which patient-reported outcome measures should be used to facilitate homogeneous reporting of outcomes.
