Purpose: to report the results of a consecutive series of 50 patients who underwent an arthroscopic excision of the sternoclavicular joint (SCJ) for primary osteoarthritis refractory to conservative treatment.
Methods: We undertook an arthroscopic excision of the SCJ in 50 patients with primary osteoarthritis refractory to conservative treatment. This included an adequate course of physiotherapy and at least 1 ultrasound-guided cortisone injection. There were 26 female and 24 male patients and the mean age at the time of surgery was 54.5 years (range 39-72 years). Patients were assessed preoperatively and at final follow-up with the Constant, Rockwood SCJ, and Quick-DASH scores. The mean follow-up was 41.8 months (range 24-73 months). Surgery was undertaken as a day-case with no shoulder immobilization.
Results: Forty-five patients were available at final-follow up. The median Constant score had increased from 55 (range 37-79) to 72 (range 38-92), Rockwood score from 6 (range 4-9) to 13 (range 4-15), and Quick-DASH 36 (range 18-69) to 12 (range 0-51). All of these changes were statistically significant (P < .0001). There were no complications and, specifically, no problems with joint instability. Forty-four of the 45 patients were pleased with the results of their surgery and indicated that they would be happy to have the procedure again.
Conclusions: The results of this study show that arthroscopic excision arthroplasty of the SCJ is a satisfactory treatment for primary SCJ osteoarthritis refractory to conservative treatment.
Level of evidence: Level IV case series.
