Arthroscopic decompression of the shoulder in athletes.

A careful history, a detailed physical examination, appropriate radiographs, and additional diagnostic tests, when indicated, usually can isolate a specific diagnosis in athletes with shoulder pain. An individual rehabilitation program frequently alleviates symptoms and allows athletes to return to their sporting activities. When nonoperative approaches fail, arthroscopic treatment with acromioplasty and coracoacromial ligament release, as appropriate, allows patients to follow through with a successful rehabilitation program. The success rate for return to non-throwing sports is very good. High-caliber athletes participating in throwing sports should be counseled regarding the possibility of a less successful outcome.

US depiction of partial-thickness tear of the rotator cuff.

PURPOSE: To test previously defined ultrasound (US) criteria for identification of partial-thickness tears of the rotator cuff. MATERIALS AND METHODS: Before shoulder arthroscopy, 52 patients with shoulder pain for more than 3 months were examined with a 7.5-MHz commercially available linear-array transducer and a standardized study protocol. The criteria used to detect partial-thickness tears were (a) a mixed hyper- and hypoechoic focus in the crucial zone of the supraspinatus tendon and (b) a hypoechoic lesion visualized in two orthogonal imaging planes with either articular or bursal extension. RESULTS: The US findings were reported as partial-thickness tears in 17 shoulders, of which three were false-positive findings. There was one false-negative finding. The sensitivity of US in depiction of partial-thickness tears was 93%, and specificity was 94%. The positive predictive value was 82%, and the negative predictive value was 98%. CONCLUSION: US can depict most partial-thickness tears with use of the criteria described.

The well-leg support.

The authors present a method of support for the well leg that allows total circumferential access to the knee, especially the medial and posteromedial sides. The method is inexpensive, easy to use, and safe. It appears to relieve stress on the lower back, which can occur with standard support. In addition, hyperextension of the hip and possible femoral nerve traction injury are avoided.

Spherocentric arthroplasty of the knee. A long-term and final follow-up evaluation.

The spherocentric knee was designed as an intrinsically stable prosthesis to manage the problems of deformity, instability, and metaphyseal bone loss in joints too severely involved to use resurfacing arthroplasty. Follow-up information has been obtained on 58 of the first 82 knees requiring spherocentric arthroplasty. After an average eight-year followup period, the results are gratifying with respect to pain, ambulatory ability, deformity, and instability. The infection and reoperation rates of 5% and 15% seem satisfactory when one considers the severely disabled patient and pathologic conditions of the knee joint.

Lateral release of the patella: indications and contraindications.

Charts were reviewed on patients at the Salt Lake Knee and Sports Medicine Clinic who had had a lateral release of the patella. Patients were divided into two groups. Group I contained patients who were entirely satisfied with the procedure, and Group II included patients who were complete failures (defined as a need for further surgical procedures). In Group I, 74 patients were included in the subjective followup. Forty of the 74 patients also had an objective followup, including roentgenograms and a physical examination. Group II contained 43 patients. Results indicated that the most predictable criterion for success was a negative passive patellar tilt. Secondary criteria included a medial and lateral patellar glide of two quadrants or less and a normal tubercle-sulcus angle at 90 degrees of flexion. Patients had less predictable results after an isolated lateral release with a positive (greater than 5 degrees) passive patellar tilt and a three quadrant or greater medial and lateral patellar glide or an abnormal tubercle-sulcus angle at 90 degrees of flexion.
