Summary
High physical activity after arthroscopic rotator cuff repair (ARCR) improves pain and function early on. Sex differences in pain perception were observed, suggesting tailored physical activity may enhance recovery.
Area of Science:
- Orthopedics
- Sports Medicine
- Rehabilitation
Background:
- The impact of physical activity on recovery after arthroscopic rotator cuff repair (ARCR) is not well understood.
- Potential sex differences in recovery outcomes following ARCR require further investigation.
Purpose of the Study:
- To investigate the effects of physical activity levels on pain, self-estimation, and strength recovery after ARCR.
- To explore potential sex differences in these outcomes.
Main Methods:
- Patients undergoing ARCR were categorized into high physical activity (HPA) and low physical activity (LPA) groups.
- Pain (VAS) and shoulder function (ASES) were assessed preoperatively and up to 24 weeks postoperatively.
- Isokinetic shoulder strength was measured at 12 and 24 weeks postoperatively.
Main Results:
- Both HPA and LPA groups showed significant improvements in pain and function over time.
- The HPA group reported significantly less pain and better function at 6 and 12 weeks post-ARCR.
- Women in the LPA group experienced higher pain levels at 12 weeks compared to men in the LPA group.
Conclusions:
- Higher physical activity is linked to improved early pain relief and functional self-estimation after ARCR.
- Structured physical activity may enhance postoperative outcomes, particularly within the first 12 weeks.
- Sex-based differences in pain perception warrant consideration in ARCR recovery protocols.
