Retrospective TKR PROMS vs Xray

Authors:

Saud, Phong, Oren, Eugenie, Eran

Ideas:

  • Patella vs No patella
  • Postop supine views and unequal space of polyethylene liner
  • Validate CPEK classification
  • Prognosis of CPEK Classification
  • Validate Hirschman classification
  • Prognosis of Hirschman classification

Future Plans

  • RCT comparing Kinematic vs Mechanical
  • Prospective cohort study comparing Kinematic vs Mechanical

Xray Measurements

  • 1. Posterior tibia slop 
  • 2. Limb alignment
  • 3. medial joint space
  • 4. Lateral joint space
  • 5. condylar offset
  • 6. mechanical lateral distal femoral angle (mLDFA)  
  • 7. The mechanical medial proximal tibial angle
  • 8. preop valgus cut angle
  • 9. postop degree of correction

PROMS

  • OKS, EQ5D, VAS
  • Preop, 6 months, 12 months, 2 years, 5 years, 10 years
