BACKGROUND The increase in the number of individuals with an unhealthy high body weight is particularly relevant in the United States. Obesity (body mass index ≥ 30 kg/m2) is a well-documented risk factor for the development of osteoarthritis. Furthermore, an increased prevalence of total knee arthroplasty in obese individuals has been observed in the last(More)
BACKGROUND AND PURPOSE The aim of short-stem total hip arthroplasty is to preserve proximal bone stock for future revisions, to improve biomechanical reconstruction, and to make minimally invasive approaches easier. It is therefore being increasingly considered to be a sound alternative to conventional total hip arthroplasty, especially for young and active(More)
The aim of the study was to develop a Dutch language version of the Foot and Ankle Ability Measure (FAAM) and evaluate its measurement properties according to the consensus-based standards for the selection of health measurement instruments (COSMIN) definitions. A forward–backward translation procedure was performed and subsequently the Dutch version of the(More)
The aim of this study was to develop a Dutch language version of the Foot and Ankle Outcome Score (FAOS-DLV) and evaluate its measurement properties according to the definitions of the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). After a standard forward–backward translation procedure, the Dutch version of the FAOS(More)
INTRODUCTION Ankle fractures often have involvement of the posterior malleolus. Treatment guidelines exist based on limited biomechanical evidence and still is considered controversial. The objective of this article is to review the biomechanical literature concerning changes in tibiotalar contract area, changes in contact pressures, changes in ankle(More)
Osteochondral defects of the femoral head represent a major challenge and various modern treatment options exist. We report a 16-year-old male with a large (3 x 3 cm) osteochondral defect of the femoral head that was treated with a partial resurfacing prosthesis combined with a high varus osteotomy, performed by surgical dislocation of the hip. Two years(More)
To translate and validate the Kujala Anterior Knee Pain Scale (AKPS) in patients who have undergone total knee arthroplasty (TKA) or unicompartmental knee arthroplasty (UKA) and evaluate the internal consistency, construct validity and ceiling or floor effect. After standard forward and backward translation was performed, 302 patients who have received a(More)
This report presents an athletic patient with swelling and progressive pain on the posteromedial side of his right ankle on weight bearing. MRI demonstrated tenosynovitis and suspicion of a length rupture. On posterior tibial tendoscopy, there was no rupture, but medial from the tendon a tissue cord came into view, causing impingement on the tendon at the(More)
OBJECTIVE To investigate which valid and reliable patient-reported outcome measures (PROMs) are available for foot and ankle disorders in the Dutch population, and which of these is the most suitable for uniform use. DESIGN Systematic review. METHOD PubMed, Embase and Google Scholar were systematically searched for relevant articles; subsequently two(More)
The aim of this study was to evaluate the responsiveness of the Foot and Ankle Outcome Score (FAOS) and provide data on the Minimally Important Change (MIC) in patients 1 year after hindfoot and ankle surgery. Prospective pre-operative and 1 year post-operative FAOS scores were collected from 145 patients. A patient’s global assessment and a longitudinal(More)
