Recent studies have shown that medial patellofemoral ligament (MPFL) reconstruction using a standardized technique provides significant improvements in all outcome scoring systems, with low complication rates and good patient satisfaction. Although numerous studies have assessed clinical results, there is little published literature investigating return to sporting activities after reconstruction of the MPFL. ⋯ Reconstruction of the MPFL is a safe and effective treatment for patellofemoral instability without severe trochlear dysplasia and allows most patients to engage in regular sports activities 2 years postoperatively, at least at a recreational level. However, potential complications, such as persistent instability, pain, and loss of flexion, must be considered.

American football players have an increased level of risk for hip injuries because of the high level of contact, biomechanical load, and anatomic strain placed on the hip joint. Many injuries are attributed to soft tissue injury rather than intra-articular lesions. However, because of improved imaging and increased knowledge, physicians are attributing unexplained hip pain to intra-articular lesions with increasing frequency. ⋯ This study demonstrated a high incidence of intra-articular pathologic lesions of the hip in a younger cohort of retired NFL players. The majority of players had bilateral hip pain. The most common finding was chondral lesions, followed by labral tears. Future research is needed to further elucidate incidence and treatment outcomes using prospective studies examining active and retired players with hip-related injuries.

The pivot-shift test is considered a reliable examination to evaluate the results of anterior cruciate ligament (ACL) reconstruction, as it strongly correlates with patient satisfaction, giving-way episodes, and activity level. The addition of lateral tenodesis (LT) to current techniques of intra-articular reconstruction with a hamstring graft could potentially improve knee laxity in cases of severe rotational instability. ⋯ Extra-articular reconstruction had little effect in reducing the anterior displacement of the tibia at 30° of flexion, but it was more effective than intra-articular reconstruction in reducing ATR. Anatomic ACL reconstruction and LT were synergic in controlling the pivot-shift phenomenon.

Anatomic techniques of ankle ligament repair have the advantage of restoring the anatomy and kinematics of the joint. This study presents a technique for anatomic reconstruction of the lateral ligament complex by way of lateral ligament advancement using suture anchors associated with immediate protected full weightbearing; 2- to 5-year clinical outcomes are reported. ⋯ This study demonstrates that anterior talofibular ligament and calcaneofibular ligament advancement using suture anchor fixation is an effective procedure for the treatment of chronic lateral ankle instability and allows immediate weightbearing.

Hamstring strains are a recognized cause of disability for athletes in many sports, but no study exists that reports the incidence and circumstances surrounding these injuries in professional baseball. ⋯ Hamstring strains are a considerable cause of disability in professional baseball and are affected by history of hamstring strain, seasonal timing, and running to first base.
