High Tibial Osteotomy (HTO) With or Without Arthroscopy of the Knee Joint

A Randomized Clinical Trial to Compare the Effectiveness of High Tibial Osteotomy (HTO) With or Without Arthroscopy of the Knee Joint on Quality of Life, Function, Pain and Swelling for Patients With Medical Compartment Osteoarthritis of the Knee

Participants will be randomized to undergo a High Tibial Osteotomy (HTO) with or without a knee scope. Patients will be tested in the Gait Lab, will fill out quality-of-life questionnaires, and have a clinical evaluation done preoperative and at each follow-up visit.

Inclusion Criteria:

• All patients booked for an HTO due to OA
• Grades II to IV severity of OA by radiographic evaluation (Kellgren & Lawrence grade)
• OA of the knee primarily involving the medial compartment

Exclusion Criteria:

• Imaging evidence of significant knee joint pathology that would change the decision to do an HTO
• An arthroscopy of the knee within 2 years of planned surgery
• Active joint or systemic infection,
• Major medical illness that would preclude undergoing surgery,
• Patients who are unwilling or unable to be assessed according to study protocol for two years following surgery
• Major psychiatric illness, developmental handicap or inability to read and understand the English language
