BACKGROUND Traditionally, the anatomical knee joint is locked in extension when walking with a conventional knee-ankle-foot orthosis. A powered knee-ankle-foot orthosis was developed to provide restriction of knee flexion during stance phase and active flexion and extension of the knee during swing phase of gait. OBJECTIVE The purpose of this study was to determine differences of the powered ...

The viability of unicondylar knee arthroplasty (UKA) as a stand-alone or temporising option for the management of gonarthrosis is a topic of considerable contention. Despite recent advances in prosthesis design and surgical technique, as well as mounting evidence of long-term survivorship, UKA remains infrequently used, accounting for just 8-15% of all knee arthroplasties. Instead this group is...

Background: A 36-year-old woman presented to the orthopedic department with painful impairment of the left knee. The pain to the medial side of the knee and locking of the knee joint had started after a distortion of the knee during a game of soccer 2 weeks earlier. On clinical exami nation, the left knee showed a flexion/extension range of 110/0°. On palpation and rotation of the knee joint, t...

BACKGROUND Knee laxity measurements have been shown to be associated with some medical conditions such as chronic joint pain and collagen tissue diseases. The aim of this study was to determine the effects of demographic factors and anthropometric measures on knee laxity. MATERIALS AND METHODS Data were collected from 521 visitors, staffs and students from the University Malaya Medical Centre...

BACKGROUND Accelerated knee osteoarthritis may be a unique subset of knee osteoarthritis, which is associated with greater knee pain and disability. Identifying risk factors for accelerated knee osteoarthritis is vital to recognizing people who will develop accelerated knee osteoarthritis and initiating early interventions. The geometry of an articular surface (e.g., coronal tibial slope), whic...

0bjective:To provide information on research investigating the relationship between a knee effusion and quadriceps inhibition. Data Sources: Peer-reviewed publications from 1965 to 1997 that investigated the effect of a knee effusion on quadriceps strength. Study Selection: The studies reviewed involved human subjects. Researchers have used active motion, electromyographic equipment, and isokin...

PURPOSE To compare the outcome following total knee arthroplasty (TKA) in obese and non-obese Asian patients. METHODS 27 obese patients were compared with 27 non-obese controls matched for age, gender, diagnosis (osteoarthritis), prosthesis, preoperative Knee Society knee and function scores, preoperative Oxford Knee Score, and follow-up duration. All TKAs were performed by a single surgeon. ...

OBJECTIVE This study was performed to investigate the factors associated with the level of knee pain in a nationally representative sample of noninstitutionalized women aged 50 years or older. METHODS Women aged 50 years or older were selected and included in the data analyses from the Korean National Health and Nutrition Examination Surveys (2010-2013). Those having malignant diseases or usi...

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...

Osteoarthritis (OA) of the knee is the commonest degenerative joint disease affecting older adults. Risk factors for the knee OA includes female gender, advanced age, overweight, obesity, previous knee injuries, previous knee surgery, and certain jobs that require continuous knee bending. Pain is the major symptom of knee OA and increased pain causes reduced physical function and poor quality o...
