Accelerated Rehabilitation following Reverse Total Shoulder Arthroplasty.

Abstract Introduction Postoperative rehabilitation is considered essential and indeed routine practice following rTSA. However, the optimal approach to postoperative rehabilitation is unknown, based on protocols for anatomic TSA, published literature is sparse, as is the quantity and quality of research evidence. Objective To outline the accelerated rehabilitation protocol (with immediate activity and no immobilization at all) following reverse total shoulder arthroplasty (rTSA) and assess its safety and effectiveness compared to the more conservative rehabilitation protocols of immobilization in a sling for 6 weeks and 3 weeks. Material and methods Between July 2005 and October 2017, 357 consecutive rTSA in 320 patients underwent a primary rTSA and were included in the study. Patients were divided into 3 groups depending on rehabilitation protocol (6 weeks or 3 weeks postoperative immobilization respectively for group 1, 2 and no-immobilization for group 3). Patients were assessed preoperatively and reviewed at 3 weeks, 3, 6, 12 months and yearly thereafter postoperatively. Constant Score (CS), Subjective Shoulder Value (SSV), patient satisfaction and pain scores were used at each appointment and patients assessed both clinically and radiographically. Results Mean age at surgery was 76 years (range 40 - 93). At 1-year follow-up, Constant Score (CS) improved from 16.6 (adjusted 23.9) to 63.2 (adjusted 91.5) in group 1 (n=114), from 21.5 (adjusted 30.7) to 67.7 (adjusted 98.4) in group 2 (n=125) and from 22.6 (adjusted 31.3) to 66.6 (adjusted 94.9) in group 3 (n=118). Pain score improved from 3.1/15 preoperatively to 12.5/15 postoperatively in group 1, from 3.5/15 to 13/15 in group 2 and from 3.7/15 to 12.5/15 in group 3. SSV improved to 8.5/10, 8.6/10 and 8.1/10 for groups 1, 2 and 3 respectively. Mean range of movement (ROM) improved to 142° elevation and 131° abduction in group 1, 153° elevation and 144° abduction in group 2 and 149° elevation and 146° abduction in group 3. No statistically significance differences were observed in CS, SSV, patient satisfaction, pain and ROM between the three groups. Less postoperative complications were observed in group 3 (No immobilization). Conclusion Accelerated rehabilitation regime post rTSA without immobilization is safe and lead to reliable good clinical results and quick return to function. This study confirms non-inferiority of the accelerated rehabilitation regime with less postoperative complications related to falls. Accelerated rehabilitation regime post rTSA have further psychological and emotional advantage to the patient, with earlier return to normal function and regaining independence. We recommend the accelerated rehabilitation regime without immobilization following rTSA.
