The purpose of this study is to counteract posterior translation of the tibia with an anterior force on the posterior proximal tibia that has been demonstrated clinically to improve posterior knee laxity following posterior cruciate ligament (PCL) injury. This study quantified forces applied to the posterior proximal tibia by two knee braces designed for […]
It has been reported that relative to other sports participants, ice hockey players suffer from cam-type femoroace-tabular impingement (FAI) in higher numbers alpha angles have been reported to increase with the likelihood of symptomatic FAI. It is unclear how prevalent increased a angles, commonly associated with cam FAI, are in asymptomatic young ice hockey […]
Knee osteochondral lesions can be debilitating. Multiple procedures have been used to manage these defects. Osteochondral autograft transplantation is one such option.
The term turf toe has been generally applied to athletic dorsiflexion injuries of the hallux metatarsophalangeal (MTP) joint. However, the typical mechanism of turf toe injuries involves the delivery of an axial load to a foot, creating a hyperextension injury to the plantar plate complex. This study analyzes the grading levels of evaluating […]
Further knee surgery after proximal tibial osteotomies has been reported to have a more difficult surgical exposure due to decreased patellar height after the osteotomy. Although a decrease in patellar height has been reported for closing-wedge proximal tibial osteotomies, it has not been widely verified among opening-wedge procedures.
Meniscal root tears present in many forms and can have profound consequences on the health of knee articular cartilage. While the biomechanics, natural history, and treatment of root tears have been increasingly investigated, the spectrum of meniscal root tear patterns observed during arthroscopic examination has yet to be defined and categorized. The purpose of this […]
All-inside meniscal repairs using bioabsorbable repair devices have been a new tool for orthopaedic surgeons in the treatment of meniscal tears.
The purpose of this study was to describe the anatomy and characterize the biomechanics of the posterolateral aspect of the canine knee. Ten adult canine knees were each used for anatomy and biomechanical testing. Distances and motion limits were measured using a 6 degree-of-freedom electromagnetic tracking system. Canine knee dissection reproducibly identified structures […]
The orthopaedic literature contains relatively little quantitative information regarding the anatomy of the posterior aspect of the knee. The purpose of the present study was to provide a detailed description of, and to propose a standard nomenclature for, the anatomy of the posterior aspect of the knee.
The fibular collateral ligament is the primary stabilizer to varus instability of the knee. Untreated fibular collateral ligament injuries can lead to residual knee instability and can increase the risk of concurrent cruciate ligament reconstruction graft failures. Anatomic reconstructions of the fibular collateral ligament have not been biomechanically validated.
