Summary
Reverse total shoulder arthroplasty (RSA) provides good long-term range of motion (ROM) and allows patients to perform daily activities. Long-term outcomes at 10 years are comparable to short-term results after RSA for cuff tear arthropathy (CTA).
Area of Science:
- Orthopedics
- Biomechanical Engineering
- Rehabilitation Medicine
Background:
- Modular reverse total shoulder arthroplasty (RSA) is a common surgical option for cuff tear arthropathy (CTA).
- Long-term objective data on the functional outcomes of RSA, particularly regarding activities of daily living (ADL), are limited.
- This study investigates the 10-year functional performance after RSA using advanced motion analysis.
Purpose of the Study:
- To evaluate the maximum range of motion (ROM) and ADL performance 10 years after RSA.
- To compare long-term functional outcomes with short-term postoperative results.
- To assess the durability and effectiveness of RSA in managing CTA over a decade.
Main Methods:
- A case control study involving 29 patients who underwent RSA, divided into a long-term group (10 years post-op) and a postoperative group (6 months post-op).
- Three-dimensional (3D) motion analysis using a Vicon system and HUX shoulder model to assess maximum ROM and activity-related ROM (AROM) during predefined ADLs.
- Statistical analysis included independent t-tests, Cohen's d for effect sizes, and ANCOVA with Bonferroni correction for age and sex adjustments.
Main Results:
- Patients 10 years after RSA showed only slightly reduced maximum and activity-related ROM compared to those 6 months post-op.
- Significant decreases in shoulder flexion for 'neck grip' and 'book' tasks, and internal/external rotation for 'armpit washing' were observed in the long-term group (p < 0.05).
- Most other movements demonstrated no significant differences between the long-term and postoperative groups, indicating sustained functionality.
Conclusions:
- RSA demonstrates good long-term ROM and enables patients to perform ADLs effectively, even a decade after surgery.
- While some specific movements showed slight declines, overall functionality remained good, highlighting the durability of RSA for CTA management.
- Further research with larger patient cohorts is recommended to validate these findings and explore factors influencing long-term outcomes.
