Arms Assigned Interventions
L.C.S. APG Knee Anterior Posterior Glide knee
Orthopaedic implant for primary knee replacement
Device: L.C.S. APG Knee Anterior Posterior Glide knee
Orthopaedic implant for primary knee replacement

Detailed Description:

Clinical and patient outcome secondary endpoints:

changes in baseline to each post operative assessment in

  1. Clinical outcome (stability, pain, range of motion and function) using the American Knee Society score
  2. Incidence of anterior knee pain and patellar function using the patellar score
  3. patient derived outcome in terms of joint specific quality of life as determined by the oxford knee score patient derived outcome in terms of general quality of life as determined by the Sf-12

Radiographic secondary endpoints:

Assessment of component alignment, positioning and radiolucencies at all post operative time points.
