ANCHOR surgeon views of patient selection and expectations for periacetabular osteotomy

Abstract

Preoperative expectations impact shared decision making and patient satisfaction. Surgeon views of patient selection, expected outcomes and patient expectations after periacetabular osteotomy (PAO) for treatment of acetabular dysplasia have not been defined. We assessed surgeon views of patient selection and expected outcomes after PAO. A sample of experienced PAO surgeons participated in semi-structured phone interviews assessing: (i) factors that determine patient candidacy for PAO; (ii) surgeon expectations for PAO outcomes; (iii) surgeon perceptions of patient expectations for PAO outcomes and (iv) surgeon perceptions of discrepancies in surgeon and patient expectations and approaches for reconciling these discrepancies. Twelve surgeons (77% of PAO-performing ANCHOR surgeons) participated. The factors most commonly mentioned in determining patient candidacy for PAO were: symptoms, radiographic findings, absence of arthritis and age. Only one-quarter of the sample mentioned patient expectations as a factor in determining patient candidacy for PAO. The most common surgeon expectations were: pain reduction, joint preservation, function with activities of daily living and return to desired activities. 58% of surgeons felt that surgeon and patient expectations align most of the time. Common expectation discrepancies included return to unrestricted activities and complete pain relief. Detailed discussion was the most commonly employed strategy to resolve expectation discrepancies. PAO surgeons felt that patient expectations of complete pain relief and return to unrestricted activities were misaligned with their own expectations. Development of an expectations survey may facilitate shared decision making.
