Abstract

Background

Joint surgery is often complicated by gradual bone and cartilage deterioration that eventually leads to secondary osteoarthritis. The primary objective of this study was to identify preoperative risk factors for gleno-humeral osteoarthritis after rotator cuff repair. The secondary objectives were to assess whether the risk of gleno-humeral osteoarthritis was influenced by the operative technique, occurrence of postoperative complications, cuff healing, and muscle degeneration and to determine whether gleno-humeral osteoarthritis affected the clinical outcome.

Hypothesis

The development of gleno-humeral osteoarthritis affects the postoperative clinical outcome.

Material and method

A retrospective multicentre study of patients who underwent rotator cuff repair in 2003 and were re-evaluated at least 10 years later was conducted under the aegis of the Société française de chirurgie orthopédique et traumatique (SOFCOT). Osteoarthritis severity was graded according to the Samilson-Prieto classification.

Results

Four hundred and one patients were included. At last follow-up, at least 10 years after surgery, the radiological Samilson-Prieto grades were distributed as follows: 0, n=181 (45%); 1, n=142 (n=35%); 2, n=57 (14%); 3, n=14 (4%); and 4, n=7 (2%). The mean Constant score was significantly higher in the patients without than with osteoarthritis at last follow-up (79/100 vs. 73/100, P<0.001). MRI assessment of cuff healing showed that the proportion of patients with osteoarthritis was significantly higher in the group with unhealed or re-torn cuffs (Sugaya type 4 or 5) than in the group with healed cuffs (Sugaya type 1, 2, or 3) (46% vs. 25%, P=0.012).

Discussion

Our study showed no associations linking the risk of gleno-humeral osteoarthritis to the patient activity profile, history of shoulder injury, or preoperative symptom duration. In contrast, statistically significant associations were identified between gleno-humeral osteoarthritis and age, male gender, initial tear severity, and the pain and mobility components of the preoperative Constant score. Decreased invasiveness of the operative technique probably diminishes the long-term risk of osteoarthritis. An unhealed or re-torn cuff increases the risk of osteoarthritis. Osteoarthritis is associated with poorer final clinical outcomes.
