Stiff knee following trauma defined as a difficulty moving the knee or a range of movement less than 90° of flexion that persists longer than 6 weeks. Better understanding of surgical timing, improved surgical technique, and advanced rehabilitation protocols has led to decreased incidence of motion. Causes contributing to a stiff knee after trauma can be separated in to intra-articular and extra-articular. A detailed history, physical examination, radiographs, and laboratory tests are important for evaluation. Prevention, consisting of control of inflammation and early motion, remains the key element in avoiding motion loss. However, certain techniques, such as manipulation under anesthesia in conjunction with arthroscopic lysis of adhesions, custom knee device, joint active system and or botulinum toxin injections are reliable treatment options. Arthroscopic lysis of adhesions, open arthrotomy or modified open lysis of adhesions, Quadricepsplasty (arthroscopic and open), percutaneous knee lysis, capsulotomy and free tissue transfer were applied.
