Summary

Mini-incision unicompartmental knee arthroplasty offers quicker recovery by minimizing disruption to the extensor mechanism. Precise component alignment and restoration of knee kinematics are achievable, highlighting the importance of a functional anterior cruciate ligament.

Area of Science:

  • Orthopedic surgery
  • Biomedical engineering

Background:

  • Unicompartmental knee arthroplasty is indicated for isolated femorotibial compartment lesions.
  • Minimally invasive techniques can reduce extensor mechanism disruption and improve recovery.

Purpose of the Study:

  • To evaluate the feasibility and outcomes of unicompartmental knee arthroplasty performed via a mini-incision.
  • To assess component alignment, radiographic precision, and functional restoration.

Main Methods:

  • Therapeutic study (Level V evidence).
  • Mini-incision technique with compartment-specific instrumentation.
  • Intra- or extramedullary femoral alignment techniques.
  • Radiographic and functional outcome assessments.
