This case involves a unique reverse Segond fracture pattern with ACL and MCL tears that does not have the usually involved PCL tear or obvious meniscal tear. It further shows the importance of recognition of the medial tibial avulsion fracture as an indicator of more severe internal derangement and instability of the knee. Early recognition prompts a more thorough evaluation and management of i...

BACKGROUND Several different etiologies cause knee pain in the pediatric and adolescent population, including anterior knee/patellofemoral pain, patellar instability, anterior cruciate ligament (ACL) tears, meniscal tears, osteochondritis dissecans (OCD) lesions, and discoid meniscus. The purpose of the current study was to determine the relative morbidity of different causes of knee pain in ch...

Anterior Cruciate Ligament (ACL) rupture is one of the most common sport injuries [1]. While the importance of the cruciate ligaments for stabilization of the knee in anteroposterior (AP) direction is evident, their influence on rotational knee stability is still discussed controversially, especially since the doublebundle technique for ACL replacement claims the advantage of improved rotationa...

The Blauth prosthesis is a hinged total knee replacement. We have evaluated 422 consecutive primary total knee arthroplasties using this design in 330 patients with a maximum follow-up of 20 years (mean 6). The mean age of the patients at the time of operation was 70 years (29 to 87). Using endpoints of infection, removal because of aseptic loosening, removal for any cause, and the worst case a...

Out of a total of 623 patients who, over a ten-year period, underwent primary total knee replacement (TKR) without patellar resurfacing, 20 underwent secondary resurfacing for chronic anterior knee pain. They were evaluated pre- and postoperatively using the clinical and radiological American Knee Society score. The mean follow-up was 36.1 months (12 to 104). The mean knee score improved from 4...
