Knee injuries are the second most common musculoskeletal injuries in primary care, with anterior cruciate the most commonly injured ligament. It is caused by contact / non-contact and accelerating/decelerating twisting injury of the knee. Typical presentation includes trauma with pain and swelling, with laxity of the knee joint. Management includes rehabilitation alone or surgery combined with ...

conversion of knee arthrodesis to total knee arthroplasty is a difficult procedure accompanied by many complications due to soft tissue and extensor mechanism contracture and bone defects. we report two cases of distal femur osteosarcoma that had been undergone wide resection arthrodesis initially. arthrodesis was converted to total knee arthroplasty with hinged prosthesis after many years. we ...

The objective of this study was to determine if disparities in hip and knee replacement surgery exist among osteoarthritis patients with AARP-branded Medicare supplement plan (ie, Medigap) coverage provided by UnitedHealthcare. Patients were selected into the study if they had 1 or more medical claims with a diagnosis of osteoarthritis from July 1, 2006 to June 30, 2007. Logistic regression ana...

Polyethylene particulate debris-induced periprosthetic osteolysis is a known complication of knee arthroplasty surgery, and may result in the need for revision surgery. The management of these bony defects can be surgically challenging, and full revisions of well-fixed total knee components can lead to substantial bone loss. We present the case of a 71 year old man who developed knee pain and o...

BACKGROUND Clinical and radiologic evaluation and analyses of the surgeries using Buechel and Pappas (B-P) knee implants. METHODS The study was conducted on 60 patients who underwent 94 total knee replacement arthroplasty with B-P knee implants from May 2009 to December 2010. The results were compared to the results of 41 patients who underwent 60 knee joint surgeries using NexGen-LPS implant...

A 49 year-old male visited a nearby clinic five years back with a complaint of pain in the right knee during exercise. Plain radiographs revealed absence of any anomalies. He began to feel a lumpy mass in his right knee two years back. The pain worsened, on imaging, an anomaly was identified in the infrapatellar fat pad of his right knee, and he was subsequently referred to our department where...

OBJECTIVE To determine changes in physical and social function during a prolonged preoperative waiting period and at 3 months after total knee arthroplasty. SUBJECTS Forty-three patients were evaluated on the day that surgery was decided, the day before surgery, and 3 months afterwards. METHODS Knee pain and function were assessed using a visual analogue scale and a functional assessment sy...

BACKGROUND Failure rates of knee ligament surgery may be high, and the impact of osseous alignment on surgical outcome remains controversial. Basic science studies have demonstrated that osseous malalignment can negatively affect ligament strain and that realignment procedures may improve knee joint stability. HYPOTHESIS/PURPOSE The purpose of this review was to summarize the clinical evidenc...

Select the studies related to knee surgery in the orthopedic literature published by Acta Ortopédica Brasileira (AOB) and the Revista Brasileira de Ortopedia (RBO) and classify them according to the levels of evidence. We selected all studies published from 2000 to 2011 related to knee surgery in AOB and RBO. The following categorization was adopted: level 1: systematic review; level 2: clinica...
