An empirical study on the effect of PNF training on the recovery of patients with medial collateral ligament injury：Randomized controlled trial

This study aims to investigate the effects of combining medial collateral ligament (MCL) reconstruction surgery with proprioceptive neuromuscular facilitation (PNF) training on knee joint function and rehabilitation outcomes. Based on these findings, relevant clinical recommendations are proposed.本研究旨在探讨联合应用内侧副韧带（medial collateral ligament, MCL）重建术与本体感觉神经肌肉促进疗法（proprioceptive neuromuscular facilitation, PNF）训练对膝关节功能及康复结局的影响，并基于上述研究结果提出相关临床建议。
