Purpose Of Review: Femoroacetabular impingement (FAI) with labral tear is an increasingly recognized source of hip pain and lost playing time in elite athletes, yet data pertaining to professional American football athletes remains scarce. Prognostic recommendations are largely limited to single-institution cohort studies. To date, no large-scale literature review of surgical treatment of FAI in elite American football athletes has been performed.

Disruptions of the lateral soft tissue restraints of the elbow, including the lateral ulnar collateral ligament, are a well-recognized clinical entity which may result in chronic elbow instability. When symptomatic, most authors recommend surgery to reconstruct the LUCL. We report on a case of a professional football player who sustained complete disruption of the lateral collateral ligamentous complex from the lateral humeral epicondyle with extension of his injury into his common extensor origin.

Purpose: This study evaluated different fibular-based reconstruction techniques for grade III posterolateral corner (PLC) injuries.

Methods: Seven fresh-frozen cadaveric knees were used in this study. A surgical navigation system was used to determine varus opening and external rotation at 0 degrees , 30 degrees , and 60 degrees with a 9.

The purpose of this study was to determine the femoral and tibial fixation sites that would result in the most isometric MCL reconstruction technique. Seven cadaveric knees were used in this study. A navigation system was utilized to determine graft isometry continuously from 0 masculine to 90 masculine.

Anterior cruciate ligament reconstruction has become one of the most common arthroscopic knee procedures, and it has excellent success rates. Intraoperative technical complications are uncommon but can be devastating to knee function. Each of the multiple steps in the reconstruction has associated complications.

Background: The medial collateral ligament is a broad ligament that functions as the primary stabilizer against valgus knee stress, particularly at 30 degrees of flexion.

Hypothesis: A double-bundle reconstruction technique that better restores the native medial collateral ligament anatomy will restore valgus and external rotation stability to a medial collateral ligament-deficient knee.

Study Design: Controlled laboratory study.

Background: Injuries to the hip account for approximately 10% of all injuries in football, but definitive diagnosis is often challenging. Although these injuries are often uncomplicated contusions or strains, intra-articular lesions are increasingly found to be sources of hip pain.

Purpose: The objective was to define the incidence and etiologic factors of intra- and extra-articular hip injuries in the National Football League (NFL).

Background: Football is one of the leading causes of athletic-related injuries. Injury rates and patterns of the training camp period of the National Football League are unknown.

Hypothesis: Injury rates will vary with time, and injury patterns will differ between training camp practices and preseason games.
