Revision surgery can improve knee motion in patients experiencing stiffness after total knee arthroplasty due to soft tissue contracture. This procedure effectively increased range of motion in cases of arthrofibrosis.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Persistent limited motion (stiffness) is a complication following total knee arthroplasty (TKA).
  • Arthrofibrosis, characterized by extensive scar tissue formation, can significantly impair joint function after TKA.

Purpose of the Study:

  • To evaluate the effectiveness of revision surgery for TKA in patients with arthrofibrosis and limited range of motion.
  • To identify potential causes and outcomes associated with stiffness after primary TKA.

Main Methods:

  • Retrospective review of six TKAs in five patients undergoing revision surgery for limited motion.
  • Assessment of implant positioning, component type (posterior cruciate retaining or substituting), and range of motion before and after revision.
  • Evaluation of heterotopic bone formation and soft tissue contracture as causes of stiffness.

Main Results:

  • Revision surgery significantly increased the arc of motion from an average of 36 degrees to 86 degrees.
  • No implant malposition or incorrect sizing was identified as the cause of stiffness.
  • Soft tissue contracture was the primary identified cause of limited motion; heterotopic bone formation was observed in some cases.

Conclusions:

  • Revision surgery can effectively restore range of motion in TKA patients suffering from arthrofibrosis and soft tissue contracture.
  • The exact triggers for scar tissue proliferation in arthrofibrosis remain unclear, potentially involving patient predisposition or response to surgical trauma.
  • While challenging, revision surgery offers a viable option for improving function and pain in cases of post-TKA arthrofibrosis.
