Personalized TKR alignment improves functional outcomes

This systematic review of alignment options in TKR describes a technique that: “like partial replacement techniques for knees… is a ‘patient specific’ and ‘ligament sparing’ technique to restore… the native pre-arthritic limb and joint alignments and knee laxity…”1

According to the authors, this technique was shown

  • To enable faster recovery,
  • Deliver better functional outcomes,
  • And lower rates of residual pain,
    compared to mechanical alignment.

At short-term follow-up (max 2 years), reoperation and revision rates were similar.

Better functional scores were attributed to the nature of the technique, which is a “true knee resurfacing” and “almost a pure bone procedure” that “reproducibly restores the patient-specific femorotibial joint obliquity and soft-tissue laxity, to generate better knee kinematics, and potentially less knee balance complications compared to mechanically aligned TKR.”
