BACKGROUND
After anterior cruciate ligament reconstruction (ACLR), diminished quadriceps strength symmetry and reduced psychological readiness to return to play (RTP) increase the risk for subsequent injury. Although the relationship between quadriceps strength symmetry and psychological readiness to RTP has been reported to be influenced by injury mechanism in female athletes, it is unclear whether such a relationship exists in male athletes.
HYPOTHESIS
Quadriceps strength symmetry would be positively associated with greater psychological readiness to RTP after ACLR, regardless of injury mechanism.
STUDY DESIGN
Retrospective cohort.
LEVEL OF EVIDENCE
Level 3 (cohort study).
METHODS
Sixty male patients completed strength testing and the Injury-Psychological Readiness to Return to Sport Scale (I-PRRS) at an outpatient clinical facility as part of return to sport testing after ACLR. Linear regression analysis was used to assess the relationship between the I-PRRS and the independent variables of interest (quadriceps strength symmetry and injury mechanism).
RESULTS
For all patients combined, no symmetry × mechanism interaction was found ( = 0.11). A significant positive relationship was found between quadriceps strength symmetry and the I-PRRS score ( < 0.001, = 0.31), after adjusting for time post-ACLR and injury mechanism.
CONCLUSION
Greater quadriceps strength symmetry was associated with greater psychological readiness to RTP after ACLR in male athletes. In contrast to what has been reported in female athletes, this relationship was independent of injury mechanism.
CLINICAL RELEVANCE
Given the potential negative consequences of quadriceps strength deficits on one's confidence to RTP, the need to restore quadriceps symmetry during the postoperative period is readily apparent. Low confidence or low psychological readiness to RTP may be indicative of quadriceps strength asymmetry or poor physical function in general.
背景
在前交叉韧带重建（ACLR）后，股四头肌力量对称性降低和重返运动（RTP）的心理准备不足会增加随后受伤的风险。尽管已经报道了女性运动员的股四头肌力量对称性与重返运动的心理准备之间的关系受到损伤机制的影响，但在男性运动员中是否存在这种关系尚不清楚。
假设
无论损伤机制如何，股四头肌力量对称性与 ACLR 后更大的重返运动的心理准备呈正相关。
研究设计
回顾性队列研究。
证据水平
3 级（队列研究）。
方法
60 名男性患者在门诊临床设施完成力量测试和损伤-重返运动心理准备量表（I-PRRS），作为 ACLR 后重返运动测试的一部分。线性回归分析用于评估 I-PRRS 与感兴趣的独立变量（股四头肌力量对称性和损伤机制）之间的关系。
结果
对于所有患者的综合分析，未发现对称性×机制交互作用（ = 0.11）。在调整了 ACLR 后时间和损伤机制后，股四头肌力量对称性与 I-PRRS 评分之间存在显著的正相关关系（<0.001， = 0.31）。
结论
在男性运动员中，股四头肌力量对称性越大，ACL 重建后重返运动的心理准备就越充分。与女性运动员的报告不同，这种关系独立于损伤机制。
临床相关性
鉴于股四头肌力量不足对重返运动信心的潜在负面影响，在术后期间恢复股四头肌对称性的需求显而易见。低信心或重返运动的心理准备不足可能表明股四头肌力量不对称或整体身体功能不佳。
