The Cost of Stiffness After Total Knee Arthroplasty

Arthroscopic Procedures Are Performed in 5% of Patients With Knee Osteoarthritis 1 Year Preceding Total Knee Arthroplasty and Are Associated With Increased Stiffness and Increased Costs

“…It has been previously reported that the postoperative management costs associated with knee stiffness may be up to 7.5 times that of patients with no knee stiffness. 28 Therefore, the costs to both the individual and health care system are high when the patient develops debilitating complications or experiences poor outcomes that necessitate additional procedures. Therefore, the authors believe that it is important to be conservative when determining the timing of TKA for a patient with a history of knee arthroscopy.…”

“…This faster recovery of active ROM may also have economic implications related to reduced knee stiffness. For example, Olsen et al [ 35 ] recently reported stiffness resulted in up to a 7.5-fold greater financial impact, as patients with stiffness required more physical therapy and clinic visits at triple the cost, had a higher revision rate (7.6% vs. 2.8%), and incurred a greater cost per patient both without ($9,401 vs. $5,259) and with ($65,771 vs. $48,287) revision surgery.…”
