The medial collateral ligament is the most commonly injured ligament in the knee. The high-speed pivoting and agility movements that are common in the sport of American Football put participants at an increased risk for a valgus force stress from contact or noncontact injuries. Positional release therapy (PRT) also considered strain/counterstrain focuses on releasing the tension in a tissue through unloading the involved body part.
Two male student-athletes participating in football with a mean age of 20.5 years were diagnosed by a physician with medial collateral ligament grade 2 sprain. Both patients sustained their injuries in a regular season game with a contact valgus force from an opposing player.
After the initial 72 hours of compression, elevation, and cryotherapy, the patients were both treated with PRT followed by progressive loading exercises. Following 4 treatment sessions of PRT over the next 6 days, the patients started with quadriceps engagement exercises, single-leg squats to 60° knee flexion, side steps, triceps dips, slow controlled lunges, and toe walk. The patients progressed to full body weight squats, single-leg landing, step-up tri-extension, and sidekicks with a leg on table. Then, the patients completed function movements and sports-specific exercises.
In this case series, 2 patients competing in intercollege American Football were treated with PRT and progressive loading exercises to facilitate return to unrestricted activities and improve outcome measures. Commonly, a grade 2 medial collateral ligament sprain is conservatively treated with return to sport taking 20 days on average. In this type 2 case series, the clinician found success utilizing PRT early in the recovery process, which in these 2 cases lead to restoration of function, outcome measure improvement, and an expedited return to sport. The expedited return to sport occurred at an average of 18 days for these patients.
内侧副韧带是膝关节最常受伤的韧带。美式足球中常见的高速旋转和敏捷动作使参与者面临因接触或非接触伤而导致的外翻力的风险增加。位置释放疗法（PRT）也被认为是应变/对侧应变，其重点是通过卸载受累身体部位来释放组织中的张力。
两名年龄均为 20.5 岁的男性大学生运动员因内侧副韧带 2 级扭伤被医生诊断为内侧副韧带扭伤。两名患者均在常规赛中因与一名来自对手的球员发生接触性外翻力而受伤。
在最初的 72 小时内进行压缩、抬高和冷敷后，两名患者均接受 PRT 治疗，然后进行渐进性负重练习。在接下来的 6 天内接受 4 次 PRT 治疗后，患者开始进行股四头肌收缩练习、单腿深蹲至 60°膝关节屈曲、侧步、三头肌下降、缓慢控制的弓步和脚趾行走。患者进展到全身重量深蹲、单腿着地、单腿上步三伸、以及用腿在桌子上进行侧踢。然后，患者完成功能运动和专项运动练习。
在这个病例系列中，两名参加校际美式足球比赛的患者接受了 PRT 和渐进性负重练习治疗，以促进恢复不受限制的活动并改善结果测量。通常，内侧副韧带 2 级扭伤采用保守治疗，平均需要 20 天才能重返运动。在这种 2 型病例系列中，临床医生发现，在恢复过程的早期使用 PRT 取得了成功，这两例患者均恢复了功能，改善了结果测量，加快了重返运动的速度。这些患者的重返运动时间平均为 18 天。
