Factors predicting patient satisfaction 2 years after total knee arthroplasty for osteoarthritis.

Objective: To identify factors predicting patient satisfaction 2 years after total knee arthroplasty (TKA) for osteoarthritis.

Methods: Prospective multicenter study of patients followed up for 2 years after TKA for osteoarthritis. We evaluated pain and function (Lequesne index and WOMAC) at baseline and after 2 years.

Reproducibility and sensitivity to change of a new method of computer measurement of joint space width in hip osteoarthritis. Performance of three radiographic views obtained at a 3-year interval.

Background: Measurement of radiographic joint space width (JSW) and of joint space narrowing (JSN) is the currently recommended method for assessment of anatomical severity and structural progression of osteoarthritis (OA), respectively. A standard radiographic view of the pelvis is commonly used for measurement of hip OA but other views are available.

Objectives: To evaluate the inter-intra reader reproducibility and the sensitivity to change of a new automated method of measurement of the hip JSW and to assess which radiographic view [pelvis anteroposterior (AP) view, hip AP view, hip oblique view] provides the greatest accuracy for JSW and JSN measurements.

Safety, efficacy and predictive factors of efficacy of a single intra-articular injection of non-animal-stabilized-hyaluronic-acid in the hip joint: results of a standardized follow-up of patients treated for hip osteoarthritis in daily practice.

Aim: To evaluate, in daily clinical practice, the efficacy and tolerability of a single intra-articular injection of non-animal-stabilized hyaluronic acid (NASHA) in patients treated for symptomatic hip OA (HOA).

Methods: Standardized follow-up (FU).

Patients: forty patients suffering from HOA treated by a single intra-articular injection of NASHA in the painful hip under fluoroscopy.

Cross-sectional study of pain and disability at knee replacement surgery for osteoarthritis in 299 patients.

Objective: To evaluate pain and disability at the time of knee replacement surgery for osteoarthritis.

Methods: In this multicenter cross-sectional study, 299 patients at 12 orthopedic surgery centers in Lyon, France were evaluated on the day before knee replacement surgery. Pain severity was assessed on a visual analog scale (VAS) and function using the Lequesne index and the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC).

Superiority of the Lyon schuss view over the standing anteroposterior view for detecting joint space narrowing, especially in the lateral tibiofemoral compartment, in early knee osteoarthritis.

Objective: To evaluate the validity of using the conventional anteroposterior (AP) radiograph of the knee in order to identify joint space narrowing (JSN) at an early stage of osteoarthritis (OA).

Methods: Grading of JSN using a 0-5 score and quantitative measurement of joint space width (JSW) of the medial and lateral compartments of the tibiofemoral joint in AP and fluoroscopically assisted posteroanterior Lyon schuss (LS) radiographs of 202 patients with knee OA.

Results: Knees without definite JSN (score <2) were twice as common in AP than in LS radiographs (36.
