The stiff total knee arthroplasty: causes, treatment modalities and results

[摘要] Total knee arthroplasty (TKA) remains the most reliable and efficacious treatment for patients with osteoarthritis resistant to conservative therapies. The stiff knee is a postoperative complication occurring in 4–16% of patients with TKA,1–5 and represents a significant cause of morbidity due to pain and restricted function.6 Risk-reduction strategies and appropriate management options should be identified to deliver optimal care plans for this group. Although there is no consensus in defining the stiff TKA, definitions in the literature refer to flexion limits ranging from 75–90°, flexion contracture greater than 10°, or a combination of the two.7,8 Multiple modalities have been used to treat the stiff TKA, including manipulation under anaesthesia (MUA), arthroscopic arthrolysis and revision arthroplasty.9–11 There is no clear management protocol for the treatment of the stiff TKA. This review has two objectives: to define the risk factors for stiff TKA and to review treatment options.
