The in vivo assessment of tibial motion in the transverse plane in anterior cruciate ligament-reconstructed knees.

Twenty-one knees with acutely injured anterior cruciate ligaments were reconstructed with patellar tendon autografts. Eight of the knees had concomitant medial ligament injuries that were not addressed surgically. Follow-up evaluation (average, 25 months) included computed tomography measurements to analyze transverse-plane laxity in both translation and rotation.

The effects of single-axis balance board intervention on balance parameters in the elderly.

Falls among the elderly contribute in large part to the morbidity and mortality statistics of this age group. To date, few institutionalized programs exist to enhance balance among the elderly as a fall prevention adjunct. A 30-day balance program was instituted at independent living facilities in our community, and the effects were assessed for subjective and objective improvement in balance parameters.

The measurement of subacromial contact pressure in patients with impingement syndrome.

This study presents the subacromial contact pressure findings in 25 patients who underwent an arthroscopic acromioplasty for impingement syndrome. All patients failed a course of conservative management before surgery. Patients were evaluated, both before and after acromioplasty, by examination, UCLA functional score, and radiographic assessment of acromial morphology.

Maneuvers for reducing dislocated hips. A new technique and a literature review.

Twelve consecutive dislocated hip prostheses and one dislocated hip joint were reduced in the emergency room using the method described in this paper. This method has multiple advantages. It uses a lever and fulcrum technique and therefore is capable of producing substantial levels of force with less effort.
