A physical therapy expert witness opines on a case that involves an eighty-one-year-old male patient with a past medical history of osteoarthritis. She previously underwent radiofrequency ablation for her joint paint, but underwent bilateral total hip replacement surgery on the recommendation of an orthopedic surgeon. Around three months following surgery, once the surgical wounds had healed, the patient began physical therapy. During his first session the physical therapist introduced the patient to a physical therapy student who he said was to be in charge of his therapy. The physical therapist left the room and the physical therapy student was unsupervised throughout the entire session. According to the patient, the PT student manipulated the patient’s right leg in an aggressive manner until the patient heard a loud pop followed by immediate excruciating pain. The patient was taken to the emergency room via ambulance. An x-ray revealed that the patient had suffered a dislocation of the hip joint. The patient had to undergo a hip revision procedure as a result.
