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. <jats:italic><jats:bold>Case Presentation<\/jats:bold>:<\/jats:italic> Two male student-athletes participating in football with a mean age of 20.5\u00a0years 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. <jats:italic><jats:bold>Management and Outcomes<\/jats:bold>:<\/jats:italic> After the initial 72\u00a0hours 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\u00a0days, the patients started with quadriceps engagement exercises, single-leg squats to 60\u00b0 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. <jats:italic><jats:bold>Conclusions<\/jats:bold>:<\/jats:italic> 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\u00a0days 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\u00a0days for these patients.<\/jats:p>","DOI":"10.1123\/jsr.2022-0206","type":"journal-article","created":{"date-parts":[[2023,8,12]],"date-time":"2023-08-12T19:02:55Z","timestamp":1691866975000},"page":"920-925","source":"Crossref","is-referenced-by-count":0,"title":["Conservative Approach to Treating American Football Players With Medial Collateral Ligament Grade 2 Sprain During the Season"],"prefix":"10.1123","volume":"32","author":[{"given":"Lucas","family":"Bianco","sequence":"first","affiliation":[{"name":"St. Luke\u2019s University Health Network, Bethlehem, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eden","family":"Jahn","sequence":"additional","affiliation":[{"name":"Alvernia University, Reading, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shannon","family":"Renninger","sequence":"additional","affiliation":[{"name":"St. Luke\u2019s University Health Network, Bethlehem, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"6","key":"r1","series-title":"Am J Orthop","first-page":"368","article-title":"Knee injuries in American football: an epidemiological review","volume":"45","author":"Rothenberg P","year":"2016","unstructured":"Rothenberg P, Grau L, Kaplan L, Baraga MG.
