Abstract

Purpose: The study objective was to compare the clinical results of reverse total shoulder arthroplasty (rTSA) and anatomical total shoulder arthroplasty (aTSA) in patients with osteoarthritis and intact rotator cuff. We hypothesised that the clinical results using rTSA would be comparable with those obtained with aTSA in this group of patients.

Methods: The study included 51 patients with shoulder osteoarthritis and intact rotator cuff who underwent rTSA or aTSA. The range of motion, Constant-Murley score and strength in external rotation were recorded pre-operatively and at the two year follow-up. Subjective post-operative results were measured using the subjective shoulder value (SSV) score and a satisfaction questionnaire.

Results: The post-operative improvement was significant in both groups, subjectively and concerning all parameters of the Constant-Murley score. Post-operatively, no significant difference was noted between the two groups for active anterior elevation (AAE), active external rotation (ER), internal rotation (IR) or Constant-Murley score (67 ± 12 in the rTSA group vs 71 ± 11 in the aTSA group). An exception was the Constant-Murley range of motion sub-score, which was better in the aTSA group (p = 0.028). No significant complications necessitating revision surgery were encountered.

Discussion: Our findings are consistent with previous studies showing good results of rTSA with shoulder osteoarthritis and intact rotator cuff with a good restoration of the IR, similar to that obtained with aTSA.

Conclusion: The rTSA is a valid option for shoulder osteoarthritis and intact rotator cuff in older adult patients.
