The Knee Injury and Osteoarthritis Outcome Score (KOOS) is one of the valid reliable tools for patient-reported assessment knee joint in cases injury or osteoarthritis, before after replacement. aim this study was to evaluate validity reliability Bulgarian version KOOS questionnaire. First, original English translated into Bulgarian, back-translated, pilot-tested clarity acceptance. Then questi...

Background: Knee range of motion is an essential outcome measure following total knee arthroplasty and it is important to measure this outcome with a simple and accurate tool. Measurement from digital photographs could provide a superior clinical alternative to the common goniometer as devices for capturing digital photographs are becoming more accessible, measurement accuracy is assisted with ...

Background The purpose of this study was to compare the functional outcomes and implant survivorship at a minimum 5 years follow-up several reconstruction techniques with or without metaphyseal cone stems variable length. Methods A retrospective comparative matched analysis performed from 2 prospectively collected databases. Only patients who underwent revision total knee arthroplasty procedure...

INTRODUCTION Meniscectomies result in altered knee biomechanics and increase contact forces on the operated knee joint. METHODS We assessed coronal knee alignment in relation to radiological osteoarthritis grading, clinical range of movement and patient reported outcome measures 40 years after total open meniscectomies in adolescence. Thirty eight knees (30 patients) that underwent total open...

BACKGROUND This study aimed at identifying preoperative predictors of patient-reported outcomes after total knee arthroplasty (TKA) and at investigating their association with the outcomes over time. METHODS We used data from 2080 patients from the Knee Arthroplasty Trial who received primary TKA in the United Kingdom between July 1999 and January 2003. The primary outcome measure was the Oxf...

BACKGROUND The International Knee Documentation Committee Subjective Knee Form (IKDC SKF) is a patient-reported knee-specific outcome measure that has been shown to be a reliable, valid, and responsive measure for patients with a variety of knee conditions. Further testing is required to compare the reliability and responsiveness of the IKDC SKF to other commonly used patient-reported outcome m...

BACKGROUND Knee osteoarthritis (OA) is the most prevalent medical condition in individuals over the age of 65 years, and is a progressive joint degenerative condition with no known cure. Research suggests that there is a strong relationship between knee pain and loss of physical function. The resulting lifestyle modifications negatively impact not only disease onset and progression but also ove...

• Objective: To compare rates of revision knee replacement (KR) surgery for patients who had 2 knees replaced simultaneously with rates for those who had staged surgery. • Design: Retrospective database study covering the period January 1985 through December 1990. • Participants: 11,771 Medicare recipients in the United States. • Main outcome measure: Rates of revision following primary bilater...

The knee range of motion is an important outcome of total knee arthroplasty (TKA). According to previous studies, the knee range of motion temporarily decreases for approximately 1 month after TKA due to postoperative pain and quadriceps dysfunction following surgical invasion into the knee extensor mechanism. We describe our experience with a knee-extension training program based on a single-j...
