Introduction: A challenge for orthopedic surgeons dealing with post-traumatic osteoarthritis of the elbow is a therapeutic procedure that maintains good mobility and functionality. Interposition Arthroplasty is a conservative procedure to alleviate arthritis and increase range of motion in a stiff elbow. This is achieved by placing graft tissues in the joint space of the elbow creating a false, but more mobile joint. It is especially popular in the younger, high demand population who desire a high functioning elbow that a total elbow arthroplasty would limit in regard to weight-bearing exercises and activities of daily living.

Methods: Through our institutions elbow pathology database, we were able to review records of patients who have received an Interposition Arthroplasty procedure from 2020-2024. We reviewed past medical history, comorbidities, time of injury, intraoperative complications, postoperative complications, pre/post operation x-rays, range of motion, and follow-up.

Results: There were 8 (3 female and 5 male) patients in this study who underwent the corrective surgery. The average age of the patient was 36 with a standard deviation of 12 years. The average follow -up time has been 5.44 months with a standard deviation of 7.85 months. 3 postoperative complications were reported which include elbow contracture with significant scarring adhesion, elbow pain, and broken medial plate involving another procedure (internal joint stabilizer).

Discussion/Conclusion: Interposition arthroplasty serves as a viable substitute for total elbow arthroplasty, especially for younger patients needing a robust and functional elbow for everyday tasks and professional activities. It is imperative for more research to develop in this area of orthopedic surgery to improve the procedure's effectiveness and longevity for the patient’s desired elbow function.
