Asymmetric Flexion Contracture is Associated With Leg Length Inequality in Patients With Knee Osteoarthritis: Data From the Osteoarthritis Initiative.

Objective: To evaluate whether knee flexion contracture (FC) was associated with leg length inequality (LLI) and/or morbidity in knee osteoarthritis (OA).

Design: We accessed 2 databases: (1) the Osteoarthritis Initiative (OAI) cohort, including participants with, or at-risk of OA, and (2) the Ottawa Knee Osteoarthritis cross-sectional database (OKOA), including participants with primary advanced knee OA. Both included demographics, radiographic data, knee range of motion, leg length, pain, and function scales.

[Cystoscopy in the outpatient clinical routine: things to keep in mind].

Cystoscopy is an important procedure in the diagnostic evaluation of the lower urinary tract. Standard cystoscopy (white light) undergoes permanent improvement. High-end instruments and video systems are available, supported by PDD (photodynamic diagnostic), NBI (narrow band imaging) and digital contrast enhancement to improve the detection rate of bladder cancer.

Baseline knee extension may be associated with volumetric cartilage loss in the anterolateral tibia: data from the Osteoarthritis Initiative.

Objectives: Animal studies suggest regional unloading of the knee due to flexion contracture (FC) results in cartilage loss in the anterior tibia. We looked for an association between the range of knee extension and articular cartilage thickness in the tibia of patients with knee OA, using quantitative MRI data from the OA Initiative.

Methods: Baseline knee extension was measured using a goniometer.

Rotator cuff anchor repair: Histological changes associated with the recovering mechanical properties in a rabbit model.

Rotator cuff anchor repair is an increasingly common surgical procedure but the failure rate remains high. In order to improve surgical outcomes, a better understanding of postrepair histological and cellular responses at the tendon-bone attachment site (enthesis) is needed. We examined operated shoulders from 42 New Zealand female white rabbits.

Preoperative bone marrow stimulation does not improve functional outcomes in arthroscopic cuff repair: a prospective randomized controlled trial.

Aims: Despite recent advances in arthroscopic rotator cuff repair, re-tear rates remain high. New methods to improve healing rates following rotator cuff repair must be sought. Our primary objective was to determine if adjunctive bone marrow stimulation with channelling five to seven days prior to arthroscopic cuff repair would lead to higher Western Ontario Rotator Cuff (WORC) scores at 24 months postoperatively compared with no channelling.
