Summary
Reverse total shoulder arthroplasty (RSA) did not significantly alter overall shoulder proprioception in patients with cuff tear arthropathy (CTA). Proprioception remained unchanged or worsened after the procedure.
Area of Science:
- Orthopedic Surgery
- Biomechanics
- Rehabilitation Medicine
Background:
- Reverse total shoulder arthroplasty (RSA) is used to improve function in shoulders with cuff tear arthropathy (CTA).
- Limited data exist on RSA's impact on shoulder proprioception.
Purpose of the Study:
- To evaluate proprioception following reverse total shoulder arthroplasty (RSA).
Main Methods:
- Fifteen patients (n=15) undergoing RSA were assessed.
- Active angle reproduction (AAR) was measured using novel 3D motion analysis (Heidelberg upper extremity model - HUX).
Main Results:
- Overall proprioception showed no significant change, remaining at 6.2° preoperatively and 6.2° postoperatively.
- Specific movements may experience proprioceptive deterioration.
Conclusions:
- RSA does not significantly improve, and may even worsen, overall shoulder proprioception.
- Further research is needed to understand the nuances of proprioceptive changes after RSA.
