Recovery of shoulder strength and proprioception after open surgery for recurrent anterior instability: a comparison of two surgical techniques.

Background: Previous studies have documented a decrease in proprioceptive capacity in the unstable shoulder. The degree to which surgical approach affects recovery of strength and proprioception is unknown.

Materials And Methods: The recovery of strength and proprioception after open surgery for recurrent anterior glenohumeral instability was compared for 2 surgical procedures.

The effect of degenerative arthritis and prosthetic arthroplasty on shoulder proprioception.

The effect of glenohumeral arthritis and subsequent total shoulder arthroplasty (TSA) on shoulder proprioception has not been evaluated previously. A prospective analysis of 20 consecutive patients with unilateral advanced glenohumeral arthritis who underwent TSA was undertaken. Shoulder proprioception testing for passive position sense and detection of motion was performed 1 week before surgery and 6 months after TSA.
