摘要

研究背景和目的:对于完全性后交叉韧带(PCL)损伤运动员的综合治疗方法仍不明确。本病例报告旨在描述等速运动项目对一名 PCL 受伤的职业足球运动员的肌肉表现和身体功能的影响:研究设计:病例报告:一名 23 岁的男性职业足球运动员在一次足球比赛中右膝(非主膝)受伤,磁共振成像证实 PCL 完全断裂。为了改善身体功能和肌肉表现,该运动员在九周的时间里完成了 23 次等速运动治疗。采用同心模式评估股四头肌和腘绳肌在 60°/s、120°/s 和 300°/s角速度下的等速运动表现。LEFS 问卷用于评估身体功能。评估在治疗开始前和九周结束时进行。为了更好地了解运动员的评估结果,还邀请了一名具有相似人体测量特征的运动员作为对照:九周后,膝关节伸肌的峰值扭矩(PT/BM)提高到 4.0 牛米/公斤(对照组:3.6 牛米/公斤),膝关节屈肌的峰值扭矩(PT/BM)提高到 2.3 牛米/公斤(对照组:1.9 牛米/公斤),速度为 60°/秒。治疗后,腘绳肌与股四头肌(H:Q)的比率(57%)反映出 PT 的增加。治疗结束后,运动员恢复了体育活动,身体功能恢复了 98.7%,以 LEFS(得分:79 分)来衡量:讨论:结果表明,等动治疗提高了膝关节的功能能力,膝关节伸肌和屈肌的PT/BM增加,扭矩保持能力增强,表明肌肉性能得到改善:5.

Physical and Muscular Performance in a Professional Soccer Player with a Posterior Cruciate Ligament Injury Following an Isokinetic Exercise Program: A Case Report.

Background and purpose: The comprehensive treatment for an athlete who sustains a complete posterior cruciate ligament (PCL) injury remains unclear. The purpose of this case report is to describe the effects of an isokinetic exercise program on muscle performance and physical function in a professional soccer player with a PCL injury.

Study design: Case Report.

Case description: A 23-year-old male professional soccer player injured his right knee (non-dominant) during a soccer match, with magnetic resonance imaging confirming a complete PCL rupture. The athlete completed 23 sessions of isokinetic treatment over nine weeks to improve physical function and muscle performance. The concentric mode was used to evaluate quadriceps and hamstrings performance isokinetically at angular velocities of 60 °/s, 120 °/s, and 300 °/s. The LEFS questionnaire was used to evaluate physical function. The assessment occurred before starting the treatment and at the end of nine weeks. An athlete with similar anthropometric characteristics was invited to participate and serve as a control, in order to better understand the athlete's assessment results.

Outcomes: After nine weeks, peak torque normalized to body mass (PT/BM) improved to 4.0 N.m/kg for knee extensors (control: 3.6 Nm/kg) and 2.3 N.m/kg for knee flexors (control: 1.9 Nm/kg) at 60 °/s. This increase in PT was reflected in the hamstrings-to-quadriceps (H:Q) ratio post-treatment (57 %). At the end of treatment, the athlete returned to sports activities with 98.7 % restored physical function as measured by the LEFS (Score: 79 points).

Discussion: The results demonstrated that the isokinetic treatment improved knee functional capacity, with increased PT/BM for knee extensors and flexors and enhanced torque-holding capacity, indicating improved muscle performance.

Level of evidence: 5.
