Summary

This trial will compare the effects of two implant techniques in knee replacement surgery: standard practice vs. kinematic alignment, which may improve ROM, pain, biomechanics & patient satisfaction.

Who is the study for?
This trial is for adults who need a total knee replacement (TKA) and can give informed consent. It's not for those under 18, with infections in the leg, severe knee instability or deformity, hip replacements on the same side, substance abuse issues, mental disorders, pregnant women, allergies to implant materials, neuromuscular diseases affecting the limb or other lower limb joint damage.
What is being tested?
The study compares two ways of aligning knee implants during surgery: 'Mechanical TKA' aligns components perpendicular to the mechanical axis; 'Anatomical TKA' aims to restore natural kinematics by matching prearthritic orientation. The goal is to see which method leads to better recovery and patient satisfaction without compromising implant longevity.
What are the potential side effects?
While specific side effects are not listed here as it depends on individual cases and surgical outcomes may vary widely from person-to-person. Generally speaking though potential risks include pain at site of surgery infection stiffness or difficulty moving your new joint bleeding blood clots nerve damage.
