OBJECTIVE Muscle strengthening exercises have been shown to improve pain and function in adults with mild-to-moderate knee osteoarthritis, but individual response rates can vary greatly. Predicting individuals who respond and those who do not is important in developing a more efficient and effective model of care for knee osteoarthritis (OA). Therefore, the purpose of this study was to use pre-...

Background. Remnant preservation was developed as a routine procedure for posterior cruciate ligament (PCL) reconstruction, but it is not easy. Objectives. Our study aimed to evaluate the outcomes of a minimum 5-years follow-up of remnant preservation PCL reconstruction. Methods. The study was a prospective cohort analysis of 44 patients who underwent PCL reconstruction with remnant preservat...

When lying supine, due to the reaction force from mattress acting mostly through heel, an external knee-extension joint-torque is induced that keeps knee fully extended. This torque becomes zero if feet are hung over end of support. study investigated, in patients with knee-osteoarthritis (knee-OA) who routinely sleep whether a change such sleeping position would ameliorate pain and associated ...

  Background: The aim of this review article is to analyze the results of high tibial osteotomy compared to unicompartmental knee arthroplasty in patients with unicompartmental knee osteoarthritis.   Methods: The search engine used was PubMed. The keywords were: "high tibial osteotomy versus unicompartmental knee arthroplasty". Twenty-one articles were found on 28 February 2015, but only eighte...

PURPOSE To identify preoperative factors (including surgeon factors) associated with outcome scores after total knee arthroplasty (TKA). METHODS Medical records of 2848 patients (3458 knees) who underwent primary TKA by 27 orthopaedic specialists were retrieved. Three specialty knee surgeons who had one-year fellowship in TKA performed 1930 TKAs, and 24 general orthopaedic surgeons performed ...

BACKGROUND There is conflicting evidence regarding the merits of patellar resurfacing during total knee arthroplasty, as many of the previous randomized controlled trials have not been adequately powered. METHODS A pragmatic, multicenter, randomized controlled trial was initiated in 1999 in the United Kingdom. Within a partial factorial design, 1715 patients were randomly allocated to receive...

Stiff-knee gait is a movement abnormality in which knee flexion during swing phase is significantly diminished. This study investigates the relationships between knee flexion velocity at toe-off, joint moments during swing phase and double support, and improvements in stiff-knee gait following rectus femoris transfer surgery in subjects with cerebral palsy. Forty subjects who underwent a rectus...

Purpose: high tibial osteotomy (HTO) is a recommended treatment for medial compartment knee osteoarthritis. Newer cartilage regenerative procedures may add benefits to the result of HTO. In this prospective study we investigate safety and also results of HTO associated with bone marrow derived cells (BMDC) transplantation in relatively young and middle aged active individuals with early osteoar...
