Conservative Approach to Treating American Football Players With Medial Collateral Ligament Grade 2 Sprain During the Season.

Abstract

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 20.5years 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 72hours 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 6days, 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 20days 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 18days for these patients.
