Chronic patellar instability after a primary dislocation event is common, and reasons for recurrent dislocations are multifactorial . Risk factors include trochlear dysplasia, insufficiencies in the medial stabilizing retinacular structures, increased tibial tubercle-to-trochlear groove (TT- TG) distance, and patella. Trochlear dysplasia reportedly is present in 85% of […]
The Latarjet procedure, which was first described in 1954, has emerged as a common surgical option for recurrent anterior shoulder instability with positive clinical outcomes. Typically, the Latarjet procedure is indicated when anterior glenoid bone loss reaches 20% to 25% because this has been reported to be the critical […]
Pain behind the knee with extension is not that common. Most posterior knee pain is present with deep knee flexion or kneeling. Therefore, it is important to understand the region of the pain to help delineate what the source of the pain may be coming from.
There are many different graft choices for ACL reconstructions, and it is important to recognize the differences among all of them. First, there is a difference between using one’s own tissues, an autograft, and using a cadaver’s tissues, called an allograft. It is well recognized in the peer reviewed literature that […]
There are many cause of pain under the kneecap and on the front part of the knee. In the past, these pain generators were generically-called either “patellofemoral chondromalacia” or “anterior knee pain.” In general, sports medicine specialists today prefer to have a diagnosis based on specific pathology. […]
Purpose Quantitative guidelines for radiographic identification of the anterior and posterior ligaments of the proximal tibiofibular joint have not been well defined. The purpose of this study was to provide reproducible, quantitative descriptions of radiographic landmarks identifying the anterior and posterior […]
Investigators found few players at the 2018 National Football League Combine had evidence of a posterolateral corner injury, with only 0.4% had residual varus symmetry on the clinical evaluation.
“[Defining] the extent and grade of posterolateral knee injuries in athletes at the NFL Combine is difficult when only subjective evaluations are assessed,” Robert F. LaPrade, MD, PhD, told Healio.com/Orthopedics. “In […]
The patient was a 24 year old male injured during a tumbling landing. He sustained a severe varus noncontact injury.
An MRI scan demonstrated a complete tear of his posterior cruciate ligament (PCL), a grade III complete posterolateral corner injury, a minimally displaced anterior tibial plateau fracture, and a medial meniscus root tear. PCL stress radiographs […]

Background: Persistent clinical instability after anterior cruciate ligament (ACL) reconstruction may be associated with injury to the anterolateral structures and has led to renewed interest in anterolateral extra-articular procedures. The influence of these procedures on knee kinematics is controversial.
Purpose/Hypothesis: The purpose was to investigate the biomechanical properties of anatomic […]
