Patients undergoing manipulation after total knee arthroplasty are at higher risk of revision within 2 years

Research output: Contribution to journalArticlepeer-review

Abstract

Background: Total knee arthroplasty (TKA) is a very common orthopedic procedure and stiffness is a common complication following TKA. There is extensive data regarding timing and success of Manipulation under anesthesia (MUA) for stiffness following TKA. However, Studies reporting outcome following MUA have often focused on the improvement in ROM and improvement in functional score with very few studies reporting on the revision risk. Methods and materials: In this study we retrospectively reviewed PearlDiver insurance database and analyzed the characteristics of the patient undergoing MUA after TKA. We also analyzed the risk of revision at 2 years in a cohort of MUA patients who were matched to patients without MUA. Result: Our study identified 9156 patients who underwent MUA within one year following TKA. MUA was slightly more common in females and risk of manipulation decreases with increasing age. Comparative analysis showed that at two years, patients in the matched MUA cohort (538 patients, 5.99%) were 2.9 times more likely to undergo revision TKA compared to the matched non MUA group (194, 2.16%)OR 2.88 (95% CI—2.44 to 3.41), P < 0.05 Conclusion: Retrospective database review showed that the risk of revision is higher in patients undergoing MUA after TKA and hence patient should be counselled about the possibility of revision in the future.
