What are the changes in the biomechanics after a knee replacement?

After a knee replacement, the biomechanics of the knee joint change significantly due to the introduction of artificial components. The new joint typically restores a more stable and aligned motion, which can enhance weight distribution and reduce pain during activities. However, patients may experience altered gait mechanics, as the artificial joint may not replicate the full range of motion or proprioceptive feedback of a natural knee. Rehabilitation is essential to adapt to these changes and improve function post-surgery.
