The amount of anteroposterior laxity required for a good range of movement and knee function in a cruciate-retaining total knee replacement (TKR) continues to be debated. We undertook a retrospective study to evaluate the effects of anteroposterior laxity on the range of movement and knee function in 55 patients following the e-motion cruciate-retaining TKR with a minimum follow-up of two years...

Understanding disease of the Cranial Cruciate Ligament The CCL is one of the most important stabilizers of the knee. It prevents hyperextension, limits internal rotation, and prevents the tibia (shin bone) from sliding forward each time the leg bears weight. When the CCL is damaged, the result is an unstable knee. This instability results in pain and inflammation. Over time, debilitating arthri...

In a prospective study, 41 consecutive patients with a partial tear of the anterior cruciate ligament, diagnosed by arthroscopy, were reviewed after an average of 17 months, having been in plaster for six weeks after injury. Their average age was 29 years and review included clinical examination, measurement of anterior and posterior laxity with the Stryker knee laxity tester as well as evaluat...

An increasing number of patients with hip fracture have been seen with osteoporosis associated with osteoarthritis. Although knee dislocation is related to high-energy trauma, low-grade injuries can also lead to knee dislocation which is defined as "ultra-low velocity dislocation." The case reported here is of an 82-year-old patient who presented with a left intertrochanteric hip fracture. Part...

Multiplanar or global laxity in arthritic knee is rare, most of this patients have neuromuscular disorder (post poliomyelitis, spinal dystrophy) or history of knee trauma. Ligament insufficiency and severe bone loss is significant in this patient. The estimated prevalence for the concurrence of charcot marie-tooth (CMT) with myasthenia gravis (MG) suggests an extremely rare event. We have prese...

[Purpose] The purpose of this study is to research the most effective knee flexion angle and ground condition in the squat position. [Subjects and Methods] The subjects of this study were 15 female college students who were able to perform squat movements and who had never previously experienced surgery, orthopedic disease, or musculoskeletal impairment. This study was conducted to examine chan...

PURPOSE Several bioabsorbable and metal options are available for internal fixation of an unstable osteochondritis dissecans (OCD) lesion, but currently there are little data on outcomes with metal headless compression screws in the adult knee. The purpose of this study was to determine (1) the radiographic healing rates, (2) midterm clinical outcomes, and (3) comparison between healed and unhe...

PURPOSE To investigate the activity of lower extremity muscles in response to single-leg stance on a training device, destabilizing the forefoot while the rearfoot stands on a fixed plate and vice versa compared with a balance pad and the floor. DESIGN Cross-sectional study. SETTING University's laboratory. PARTICIPANTS Twenty-seven healthy adults. METHODS Surface electromyography and 2...
