Knee manipulation after total knee arthroplasty (TKA) did not improve final flexion and was associated with increased femoral thickness. Factors like patient age or time to manipulation did not correlate with outcomes in TKA patients.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Radiology

Background:

  • Knee stiffness is a potential complication following total knee arthroplasty (TKA).
  • Knee manipulation is a procedure sometimes performed to address stiffness after TKA.
  • Understanding factors associated with stiffness and outcomes of manipulation is crucial for patient management.

Purpose of the Study:

  • To identify factors associated with knee stiffness after TKA.
  • To evaluate the outcomes of knee manipulation in patients experiencing stiffness post-TKA.
  • To compare radiographic changes between manipulated and non-manipulated TKA patients.

Main Methods:

  • Retrospective review of medical records and radiographs of TKA patients.
  • Matching patients who underwent knee manipulation with a control group who did not.

  • Analysis of patient demographics, surgical history, range of motion, and radiographic measurements.
  • Main Results:

    • Manipulated TKA patients showed decreased hospital discharge and final flexion.
    • Patient age, time to manipulation, and preoperative flexion did not correlate with final flexion.
    • Manipulated group had increased postoperative anteroposterior femoral thickness; patellar height decreased in both groups without significant difference in change.

    Conclusions:

    • Knee manipulation after TKA did not improve final flexion and was linked to increased femoral thickness.
    • Factors such as age and timing of manipulation did not predict final flexion.
    • Further research may be needed to understand the long-term effects and optimal management of stiffness after TKA.
