Stiffness after total knee replacement (TKR) can stem from various factors, including surgical technique and patient predisposition. Early identification and intervention, such as manipulation under anesthesia, are key to improving range of motion.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Stiffness is a common and frustrating complication following total knee replacement (TKR).
  • Defining TKR stiffness involves limitations in flexion (<75°) and extension (15° lack).
  • Preoperative stiffness is a significant predictor of postoperative motion deficits.

Purpose of the Study:

  • To review the causes and management strategies for stiffness after total knee replacement.
  • To highlight the importance of surgical technique and patient factors in preventing and treating TKR stiffness.
  • To discuss the variable outcomes of reoperations for stiff TKR.

Main Methods:

  • Review of literature on TKR stiffness causes, definitions, and management.
  • Analysis of surgical considerations including osteophyte removal, component alignment, and soft tissue balancing.

Minimally Invasive Treatment for Thoracolumbar Burst Fracture Using Sagittal Alignment Screws and A Trauma Reduction Device

Published on: November 8, 2024

  • Discussion of non-surgical interventions like patient expectation management and rehabilitation.
  • Evaluation of potential causes such as arthrofibrosis, complex regional pain syndrome, and infection.
  • Consideration of reoperation strategies including manipulation under anesthesia and surgical revisions.

    • Main Results:

    • Optimal surgical technique, including proper component placement and soft tissue balance, is crucial.
    • Patient factors, such as a predisposition to scar tissue formation, can influence outcomes.
    • Early intervention, including manipulation under anesthesia, may be necessary if motion plateaus.
    • Reoperation success for stiff TKR is variable and depends heavily on the underlying cause.

    Conclusions:

    • Preventing TKR stiffness involves meticulous preoperative planning and intraoperative technique.
    • Identifying the specific etiology of stiffness is critical for successful treatment.
    • While surgical revisions can improve motion, outcomes are often unpredictable, especially in cases of arthrofibrosis.
