Range-of-Motion Predictors for Repeat Manipulation Under Anesthesia and Revision Surgery for Stiffness After Total Knee Arthroplasty.

ABSTRACT:

Introduction

Manipulation under anesthesia (MUA) is a first-line treatment for stiffness after total knee arthroplasty (TKA), but predicting outcomes after MUA can be difficult.

Purpose

We sought to determine the association between pre-MUA range-of-motion (ROM) and the risk of repeat MUA and revision in patients who underwent primary TKA.

Methods

We conducted a retrospective review of 543 MUAs for stiffness at a single institution. Mean age was 62.5 years, and 64% were female. Second MUA or revision TKA were considered failures of treatment. Penalized logistic regression models were used to assess risk factors for failures. The Kaplan-Meier survivorship was used to examine survivorship free from second MUA or revision.

Results

Before and after MUA, there was s
