THE EFFECTS OF THERAPEUTIC INTERVENTION FOLLOWING PFA ON GAIT, ROM, AND PAIN: A CASE REPORT. Laura M. Fleck*; Corey Snyder; Mark J. Carroll University of Findlay, Findlay, OH PURPOSE: The purpose of this case report was to examine the effectiveness of a patellofemoral arthroplasty (PFA) on a single patient for treatment of chondromalacia patellae on improving functional capacity, pain, ROM and gait. BACKGROUNDS/SIGNIFICANCE: There is a relative lack of literature on patient outcomes following patellofemoral arthroplasty (PFA) for chondromalacia patellae within the 2 month period post-op. The majority of literature available on therapeutic success following this procedure is retrospective, ranging from 3-20+ years post-op SUBJECTS: The patient was a 50 year old female who was born with a slightly lateral quadriceps tendon insertion, causing signs and symptoms of chondromalacia patellae in adolescence. She had a significant past medical history of unsuccessful treatments for chondromalacia patellae. METHODS AND MATERIALS: The patient was seen twice a week for 7 weeks at an outpatient clinic, with a comprehensive HEP for home completion. Therapeutic intervention included manual therapy, Hi-Volt stimulation, cryotherapy, therapeutic exercise, pilates, soft tissue mobilization, gait retraining, and neuromuscular re-education. ANALYSES: Statistical analysis was not completed due to the single subject study design. RESULTS: At the time of discharge the patient had improved her antalgic gait, increased ROM, and decreased pain, all of which resulted in an increased functional capacity. CONCLUSIONS: The PFA proved to be successful in treating this patients condromalacia patella signs and symptoms whereas other treatment options were unsuccessful. FUNDING SOURCE: There was no funding used in this case report.
