Biomechanical Changes After Reverse Total Shoulder Arthroplasty: A Systematic Review of Advanced Measurement Technologies

Key Points

• The aim is to analyze biomechanical changes post reverse total shoulder arthroplasty and identify gaps in existing measurement technologies.
• Conducted a systematic review of literature on reverse total shoulder arthroplasty
• Examined the role of scapulothoracic motion and deltoid-driven strategies
• Assessed need for standardized, longitudinal studies using high-fidelity kinematics and EMG
• Highlighted the importance of reporting implant design and technique
• Found that postoperative movement is largely compensatory rather than mechanical normalization
• Identified significant gaps in current measurement technologies for assessing outcomes
• Suggested that surgical techniques affect functional recovery, requiring better data integration
