The cause of arthrofibrosis is multifactorial and incompletely understood. Increased preoperative and postoperative inflammation reflected by swelling, effusion, and hyperthermia also plays an important role in the development of this complication.7,11 On MRI, fibrotic tissue encases the ACL graft and can extend anteriorly into the infrapatellar fat pad and suprapatellar bursa or posteriorly to the posterior joint capsule (Figure 8).7.

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. Knee postoperative stiffness manifests as an insufficient range of motion, which can be caused by poor graft position, cyclops lesions, and arthrofibrosis [5,6,7].
