Achieving high flexion in total knee replacement (TKR) depends more on a patient's preoperative range of motion (ROM) than implant design. Many patients may not qualify for high-flex designs if extensive preoperative ROM is required.

Area of Science:

  • Orthopedic surgery
  • Biomedical engineering
  • Reconstructive surgery

Background:

  • The goal of total knee replacement (TKR) is to restore pain-free flexion up to 155 degrees with stability.
  • Current TKR implant designs focus on shortening radii of curvature, potentially increasing bone removal and complications.

Purpose of the Study:

  • To evaluate the factors influencing postoperative range of motion (ROM) in total knee replacement (TKR).
  • To assess the suitability of high-flex total knee arthroplasty (TKA) designs based on patient preoperative ROM.

Main Methods:

  • Review of existing literature on TKR implant design, surgical techniques, and patient outcomes.
  • Analysis of factors predicting postoperative range of motion (ROM).

Main Results:

Related Experiment Videos

  • Preoperative range of motion (ROM) is a stronger predictor of postoperative ROM than implant design.
  • Current high-flex TKA designs may necessitate significant preoperative ROM, potentially excluding many patients.

Conclusions:

  • Patient's preoperative range of motion (ROM) is critical for achieving high flexion after total knee replacement (TKR).
  • The criteria for qualifying for high-flex total knee arthroplasty (TKA) may need re-evaluation based on preoperative ROM rather than solely implant design.
