Manipulation under anesthesia (MUA) is the first-choice treatment for stiffness following total knee arthroplasty (TKA) unresponsive to pain management and physiotherapy. Some of predisposing factors patient-reported outcome measures (PROMs) MUA remain poorly studied. We retrospectively investigated etiological risk outcomes MUA.391 TKA patients from a randomized trial comparing use tourniquet (spinal or general) were analyzed, needing identified (MUA group). evaluated in-hospital opioid consumption, Oxford Knee Score (OKS), range motion (ROM), assessed by Brief Pain Inventory-short form with 1-year follow-up.39 (10%) identified. The younger (60 years vs. 64 years, difference -4, 95% CI -6 -1) had higher postoperative oxycodone consumption (66 mg 51 mg, median 11, 1-22) than no-MUA patients. proportion who contacted emergency department within 3 months because was larger that non-MUA (41% 12%, OR 5, 3-10). At follow-up, ROM improved 39° MUA, but worse in group (115° 124°, p < 0.001). No found OKS between patients.Higher seems predict risk. performed postoperatively offers substantial improvement comparable PROMs 1 year after TKA.
