Meet your surgeon.
Dr Christiaan Rudolf Oosthuizen is an Orthopaedic Surgeon with more than 35 years of experience in private practice. His work focuses on knee, hip and spinal surgery, with a particular interest in contemporary partial knee replacement and the KOGS grading system.
Read full biographyThe KOGS Grading System.
The Knee Osteoarthritis Grading System (KOGS) is the diagnostic framework Dr Oosthuizen uses to determine the precise threshold for surgical intervention — and to identify the patients who will benefit most from a UKA rather than a full replacement.
Early wear — non-operative management, biomechanical correction and orthobiologics.
Focal unicompartmental wear — the primary candidate window for UKA.
Multi-compartment progression — strategic assessment for total knee or staged options.
End-stage disease with deformity — total knee arthroplasty with full kinematic planning.

Unicompartmental Knee Arthroplasty — the resurfacing solution.
For appropriately selected patients with single-compartment wear, the UKA preserves bone, ligaments and natural knee kinematics — with a smaller incision and a markedly faster return to function than a total replacement.
See how UKA compares to TKADecades of orthopaedic practice and ongoing research in knee arthroplasty.
Dr Oosthuizen's practice combines private clinical work with peer-reviewed academic contributions on unicompartmental knee arthroplasty methodology and outcomes.
