Systematic review demonstrates surgical techniques impact biomechanics and recovery after shoulder surgery, indicating the need for improved measurement methods.
rTSA restores forward elevation primarily via compensatory scapulothoracic motion and deltoid-driven neuromuscular strategies rather than normalization of glenohumeral mechanics. Standardized, longitudinal studies integrating high-fidelity kinematics, EMG, and real-world activity monitoring, with explicit reporting of implant construct parameters, are needed to clarify how surgical technique and implant design influence postoperative biomechanics and functional recovery.
