Treatment options for arthrofibrosis following total knee arthroplasty include manipulation under anesthesia, open or arthroscopic arthrolysis, and revision surgery to correct identifiable problems. We propose preoperative low-dose irradiation and Constrained Condylar or Rotating-hinge revision for severe, idiopathic arthrofibrosis. Irradiation may decrease fibro-osseous proliferation while constrained implants allow femoral shortening and release of contracted collateral ligaments. Fourteen patients underwent fifteen procedures for a mean overall motion of 46 degrees and flexion contracture of 30 degrees. One patient had worsening range of motion while thirteen patients had 57 degrees mean gain in range of motion (range 5-90 degrees). Flexion contractures decreased by a mean of 28 degrees. There were no significant complications at a mean follow up of 34 months (range 24 to 74 months).
