Key result
Higher preoperative expectations predict improved PROMIS pain interference and expectation fulfillment two years post-ACLR.
Why the study?
Patient expectations potentially impact postoperative outcomes in orthopaedic surgery, but the association between preoperative expectations and patient-reported outcomes after anterior cruciate ligament reconstruction has not been thoroughly investigated.
Are preoperative expectations associated with patient-reported outcomes 2 years after primary anterior cruciate ligament reconstruction?
Population
129 patients undergoing primary ACLR at an academic institution
Comparison
Higher vs lower preoperative expectations
Design
Retrospective cohort study
Follow-up
2 years

Preoperative expectations may aid risk stratification for pain after ACLR; leaves open whether modifying them improves outcomes.

Are preoperative expectations associated with patient-reported outcomes 2 years after primary anterior cruciate ligament reconstruction?
p-value: p=0.030
Preoperative expectations are predictive of improved 2-year pain-related outcomes and a greater sense that expectations were met after primary ACLR.
Swamykumar et al. (2026) conducted a cohort in Primary anterior cruciate ligament reconstruction (n=129). Preoperative expectations was evaluated on Patient-reported outcomes (PROs) including PROMIS domains, IKDC, TAS, MARS LE, and NPS (p=0.030). Higher preoperative expectations predicted improved 2-year PROMIS Pain Interference (p=0.030) and a greater sense that expectations were met (p=0.038) after primary ACLR.
