Factors associated with subjective shoulder function preoperatively and postoperatively after arthroscopic rotator...

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Rehabilitation Science

Background:

• Subjective shoulder function is crucial after arthroscopic rotator cuff repair (ARCR).
• Identifying factors influencing functional recovery guides postoperative rehabilitation strategies.
• Understanding these factors can optimize patient outcomes and treatment plans.

Purpose of the Study:

• To investigate the factors associated with subjective shoulder function after ARCR.
• To analyze changes in these factors across different postoperative time points.
• To provide insights for tailored rehabilitation protocols.

Main Methods:

• A cohort of 104 patients undergoing ARCR with at least 12 months follow-up was analyzed.
• Subjective shoulder function was assessed using the Shoulder36 (Sh36) 5 domain scores preoperatively and at 6 and 12 months postoperatively.
• Stepwise multivariable regression identified factors including range of motion (ROM), strength, pain, and cuff integrity.

Main Results:

• Preoperatively, active abduction ROM was associated with all Sh36 domains.
• At 6 months postoperatively, isometric external rotation strength became the significant factor, not ROM.
• At 12 months, pain score was the most associated factor across multiple Sh36 domains.

Conclusions:

• Factors influencing subjective shoulder function significantly differ between preoperative and postoperative periods after ARCR.
• Postoperative rehabilitation strategies should be adapted based on the specific recovery phase.
• Tailoring treatment to the evolving factors can enhance functional recovery.
