Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • The optimal patellar mobilization technique during total knee replacement (TKR) is debated.
  • Lateral retraction is proposed as potentially more beneficial than patellar eversion.

Purpose of the Study:

  • To investigate the functional outcomes of patellar eversion compared to lateral retraction in TKR patients.
  • To provide clinical guidance for TKR surgical procedures.

Main Methods:

  • A single-center, prospective, randomized controlled trial involving patients undergoing unilateral TKR.
  • Patients were randomized to either lateral retraction or eversion patellar exposure techniques.
  • Primary outcomes included operation time, hospital stay, and straight leg raising time; secondary outcomes covered functional scores and range of motion.

Main Results:

  • Results are pending publication in peer-reviewed journals.

Conclusions:

  • The study aims to systematically evaluate the functional outcomes of patellar eversion in TKR.
  • Findings will inform clinical decision-making for TKR patient management.
