High resolution MRI evaluation of meniscal volume and anthropometric correlations.

The purpose of this study was to digitally determine meniscal volumes, and compare them with linear and surface area anthropometric measurements to evaluate these measurements for meniscal allograft sizing. Eighteen subjects (10 male and 8 female; mean age 37.5 years) underwent 3.

3.0-Tesla MRI and arthroscopy for assessment of knee articular cartilage lesions.

The purpose of this study was to evaluate the ability of 3.0-Tesla magnetic resonance imaging (MRI) to accurately assess knee articular cartilage lesions. Sixteen patients who had knee 3.

Human knee synovial fluid cytokines correlated with grade of knee osteoarthritis--a pilot study.

Unlabelled: The purpose of this pilot study was to evaluate the cytokine profile of human knee synovial fluid and correlate this with the subject's degree of articular cartilage degradation, radiographic score, and synovial histology.

Materials And Methods: Synovial fluid was withdrawn before knee meniscectomy in 12 subjects with varying degrees of osteoarthritis and assayed for 21 cytokines, using a multiplex cytokine assay and flow cytometry instrumentation. Articular cartilage surfaces were scored by a single orthopaedic surgeon on the basis of the International Cartilage Repair Society (ICRS) classification during the arthroscopy, and posterior-anterior knee radiographs were graded using the Kellgren-Lawrence (KL) classification.

Quantification of two-dimensional glenohumeral rhythm in persons with and without symptoms of shoulder impingement.

A repeated-measures design was used to assess glenohumeral rhythm in 10 patients with shoulder impingement and 10 pain-free persons and to assess the effects of subacromial injection on glenohumeral rhythm within the impingement group. Scapular-plane anterior-to-posterior x-rays of the scapula and humerus were obtained at 5 angles of arm elevation (resting, 30 degrees, 60 degrees, 90 degrees, 120 degrees). For the impingement group, x-rays were repeated after subacromial injection (10 mL of 1% lidocaine).

The immediate and long-term effects of exercise and patient education on physical, functional, and quality-of-life outcome measures after single-level lumbar microdiscectomy: a randomized controlled trial protocol.

Background: Low back pain remains a costly quality-of-life-related health problem. Microdiscectomy is often the surgical procedure of choice for a symptomatic, single-level, lumbar disc herniation in younger and middle-aged adults. The question of whether a post-microdiscectomy exercise program enhances function, quality of life, and disability status has not been systematically explored.

Strengthening the supraspinatus: a clinical and biomechanical review.

Rotator cuff weakness has been implicated as a cause of subacromial impingement. Numerous exercises have been advocated to strengthen the rotator cuff, particularly the supraspinatus. The clinical rationale and two exercises advocated for strengthening the supraspinatus, the empty can and the full can, were evaluated.
