1 级肌肉和韧带撕裂通常通过保守治疗而痊愈,伴最少的长期并发症。[12]Kalimo H, Rantanen J, Jarvinen M. Muscle injuries in sports.

2 级撕裂在最初的 4 至 6 周内存在撕裂扩大的高风险,因此应避免在短时间内恢复工作。[12]Kalimo H, Rantanen J, Jarvinen M. Muscle injuries in sports.

3 级肌肉撕裂可能合并重要的并发症如肌萎缩、肌肉纤维化、异位骨化和骨筋膜间室综合征。 无论采用哪种治疗选项,3 级韧带撕裂均可导致慢性不稳定、疼痛、功能丧失和关节继发性退行性病变。[12]Kalimo H, Rantanen J, Jarvinen M. Muscle injuries in sports.
