Purpose

The Appropriate Use Criteria (AUC) for the surgical treatment of knee osteoarthritis were developed by the American Academy of Orthopedic Surgeons (AAOS) to guide surgeons in selecting the most evidence-based surgical option. This study aimed to assess the usability of the AUC by comparing the actual surgical treatment provided at our institution with that recommended by the AUC.

Methods

A retrospective review of the medical charts and radiographs of all patients who underwent surgery for knee osteoarthritis (OA) at our hospital was performed between January and December 2017. Data including each patient’s age, gender, pain level, mechanical symptoms, range of motion (ROM) and instability, radiographic pattern and severity, limb alignment, and type of surgical interventions received were collected.

The collected data were input into the AUC application to determine the rate of appropriateness of the treatments. Afterwards, the agreement between the actual treatment provided and the AUC recommendation was assessed.

Results

A consecutive series of 100 patients were included. The mean age was 63.1 years, with the majority of the patients aged (73%) between 50 and 69 years. Most of the patients were females (74%), and 61% had left knee OA. The most frequent type of patient was a middle-aged patient with function-limiting pain at short distances, no mechanical symptoms or functional instability with full ROM, severe knee multicompartmental radiographic features, and varus or valgus malalignment. Out of the 100 patients, total knee arthroplasty (TKA) was performed in 85 patients, unicompartmental knee arthroplasty (UKA) was performed in 11 patients, and high tibial osteotomy (HTO) was performed in four patients.

According to the AUC, 90 (90%) cases were treated with an appropriate surgical treatment, whereas 10 (10%) cases were treated with a maybe appropriate treatment. The actual surgical treatment performed at our hospital was in agreement with the AUC recommendation in 100% of the TKA cases, 90.9% of the UKA cases, and 100% of the HTO cases. Thus, the agreement rate with the AUC was 99% in all surgical cases.

Conclusion

This study demonstrated that the AUC for the surgical treatment of knee OA can be applied easily in a clinical setting. Most of the treatments provided at our institution were appropriate and in agreement with the AUC recommendations. Additionally, the AUC had a web-based application that was easy to use and simple for identifying treatment recommendations.
