Description
Summary:Background Proprioceptive capabilities play an important role in stability of the shoulder joint. Hypothesis Decreased proprioceptive capabilities can improve by surgical repair of shoulder instability. Study Design Prospective long-term study. Methods The proprioceptive capabilities of 14 patients with recurrent anterior shoulder instability were examined preoperative and with a minimum follow-up of 5 years postoperative using the angle reproduction test. The patients' data were compared to a healthy control group. Results The joint position sense improved significantly in abduction, flexion, and rotation (P< .05). The preoperative difference from the target joint position was 9.3 ° (SD, 4.6 °) for the summarized positions in abduction, 9.1 ° (SD, 4.5 °) in flexion, and 10.1 ° (SD, 5.1 °) in rotation. Postoperatively, it improved to 5.6 ° (SD, 2.9 °) in abduction, 5.6 ° (SD, 2.7 °) in flexion, and 5.0 ° (SD, 1.8 °) in rotation. The joint position sense of the uninvolved contralateral shoulder improved too. Conclusions Five years after surgical repair for shoulder instability, the joint position sense improved significantly, to a level of normal, healthy shoulders.
