The incidence of arthrofibrosis following TKA is approximately 4%.17 Arthrofibrosis as the cause for TKA revision ranges from 4.5 to 6.9%.18,19 Multiple factors affect the development of arthrofibrosis following TKA, including surgical technique, component selection, post-operative rehabilitation course, underlying patient-specific disease and genetic factors, and preoperative range of motion.18,19Some authors suggest a relationship between diffuse arthrofibrosis and chronic infection.18,20,21 Pre-operative range of motion appears to be the most important predictor of postoperative stiffness.18,20,22 Arthrofibrosis associated with TKA most often appears within 5 years of surgery.19 Stiffness and arthrofibrosis developing after 5 years is often associated with other complications such as aseptic loosening, infection, or polyethylene wear.19, With specific techniques and modifications to reduce metal artifacts, MRI is effective in evaluating the complications of TKA including implant loosening, periprosthetic infection, fractures, extensor mechanism injury, polyethylene wear, and arthrofibrosis. 10(5): p. 489-500, American Journal of Sports Medicine.

Patellar clunk syndrome results from localized fibrous tissue forming at the quadriceps insertion on the proximal pole of the patella and can be seen in up to 3.5% of posterior-stabilized TKAs.23 Patients present with a locking sensation or decreased motion during flexion and extension.17 An audible clunk may be observed on physical exam when the knee is extended from the flexed position, presumably from entrapment of the tissue in the intercondylar notch with flexion and abrupt displacement with extension (Figure 14).

Various terms have been used to describe this pathology including infrapatellar contracture syndrome, synovial fibrosis of the infrapatellar fat pad, scarring of the anterior interval, and patella infera syndrome.12,15,16 Postoperative scarring normally appears as thin linear or spiculated regions of low signal on all sequences with small slightly thickened and more nodular portions found along the route of the arthroscopic portals and at the posterior margin of the fat pad (Figure 9).16 In contrast, symptomatic fibrosis results from more extensive fibrotic changes appearing as thickened and irregular areas of low signal on all sequences, which can greatly reduce the amount of normal fat.
