PURPOSE: We sought to evaluate (1) clinical and radiologic results after arthroscopic calcific deposit (CD) removal and (2) the relevance of remnant calcifications (RCs).
METHODS: The study included 102 patients undergoing arthroscopic CD removal, preserving integrity of the rotator cuff. Postoperatively, we divided patients into 2 groups according to the extent of CD removal achieved. Group 1 consisted of patients with complete CD removal. Group 2 included patients showing minor RCs. Ninety-three patients (99 shoulders) completed follow-up. The mean patient age was 50.6 years (31 to 68 years), and the mean follow-up period was 37.3 months (24 to 83 months). We obtained anteroposterior (AP) and outlet radiographs before surgery, postoperatively, and at follow-up. We used the absolute and age- and sex-related Constant scores (CSabs, CSrel) as outcome measures. We compared both groups statistically (Mann-Whitney U test; P < .05).
RESULTS: Complete CD removal was achieved in 82 of 99 (82.8%) shoulders (group 1). Postoperatively, minor RCs were found in 17 of 99 (17.2%) shoulders (group 2), an average of 58.6% (± 26.2) of the mean preoperative size. All RCs showed complete (14 of 17) or virtually complete (3 of 17) resolution at follow-up. Overall mean CSabs and CSrel were 88.8 points (± 10.4) and 99.0% (± 3.7), respectively. Mean values of CSabs and CSrel in group 1 (89.5 points ± 9.5 and 99.1% ± 3.7, respectively) and group 2 (86.1 points ± 12.9 and 98.7% ± 4.2, respectively) did not differ.
CONCLUSIONS: Arthroscopic CD removal, preserving integrity of the rotator cuff yielded good to excellent results in 90% of patients and avoided iatrogenic tendon defects in all patients. Minor RCs did not impair clinical outcome and spontaneously resolved at follow-up.
LEVEL OF EVIDENCE: Level IV, therapeutic case series.
