Upper extremity (UX) movement analysis by means of 3D kinematics has the potential to become an important clinical evaluation method. However, no standardized protocol for clinical application has yet been developed, that includes the whole upper limb. Standardization problems include the lack of a single representative function, the wide range of motion of(More)
Kinematic studies, in which mobile- and fixed-bearing total knee arthroplasty (TKA) were compared, showed controversial results with respect to axial femorotibial rotation. However, all studies focused only on straight ahead tasks, which may underestimate possible differences in freedom of rotation. The purpose of this study was to investigate the influence(More)
Postoperative urinary retention is a common complication after major orthopedic procedures of the lower limb. In total hip arthroplasty and total knee arthroplasty, the incidence ranges from 7% to 84%. In this study, the incidence and risk factors for postoperative urinary retention were described in a cohort of 376 men undergoing total hip arthroplasty.(More)
STUDY DESIGN Systematic literature review. OBJECTIVES To perform a systematic review of the literature on prognostic factors for successful recovery after arthroscopic rotator cuff repair. BACKGROUND Rotator cuff lesion is a common shoulder disorder, with a prevalence ranging from 13% in people over 50 years of age to more than 50% in people over 80(More)
Disease-specific instruments of quality of life (QOL) are more sensitive to disease-specific changes. The purpose of this study is to identify prognostic factors for disease-specific QOL after all-arthroscopic rotator cuff (RC) repair using the Western Ontario Rotator Cuff Index (WORC). A total of 140 patients were evaluated after an RC repair with a mean(More)
PURPOSE The aim of this study was to compare a broad range of total knee prostheses with different design parameters to determine whether in vivo kinematics was consistently related to design. The hypothesis was that there are no clear recognizable differences in in vivo kinematics between different design parameters or prostheses. METHODS At two sites,(More)
OBJECTIVE To assess the relationship between knee varus-valgus motion and functional ability, and the impact of knee varus-valgus motion on the relationship between muscle strength and functional ability in patients with osteoarthritis (OA) of the knee. METHODS Sixty-three patients with knee OA were tested. Varus-valgus motion was assessed by(More)
BACKGROUND The WORC is a quality of life questionnaire designed for patients with disorders of the rotator cuff, originally developed in English. The purpose of this study was to cross-culturally adapt the WORC for use in the Dutch population and to evaluate reliability, agreement and floor and ceiling effects of this Dutch version in a population of(More)
The assessment of knee joint laxity is clinically important but its quantification remains elusive. Calibrated, low dosage fluoroscopy, combined with registered surfaces and controlled external loading may offer possible solutions for quantifying relative tibio-femoral motion without soft tissue artefact, even in native joints. The aim of this study was to(More)
OBJECTIVE To determine the validity of varus-valgus motion as a measure of knee joint stability by establishing the relationship of varus-valgus motion with muscle strength, joint proprioception, joint laxity and skeletal alignment in patients with knee osteoarthritis (OA). METHODS Sixty-three patients with OA of the knee were tested. Varus-valgus motion(More)
