Background:
Total Knee Arthroplasty (TKA) is today a standard procedure in
the operative treatment of osteoarthritis in the knees. Various authors has
described that malalignment may lead to early loosening.
Purpose / Aim of Study:
For this reason the CASPAR robot- assisted total
knee replacement was introduced. This studie is a 10-12 year follow up, on the
total Knee Arthroplastys, made with CASPAR from 2000–2002, at Faaborg
Hospital, Denmark.
Materials and Methods:
Forthy consecutive TKAs were performed between
2000
and 2002. Patients were followed up retrospective 10-12 years post
surgery. Outcome measures included Oxford Knee Scores (OKS) and EQ-5D
scores. Survival analysis was performed using the life table method.
Findings / Results:
Of 40 CASPAR knees, 34 were alive at 10-12 years. 4
patients were lost to follow up. 1 knee (3,3%) were revised, for aseptic
loosening. The 10 year survival was 96,6%. The mean Oxford Knee Score was
21
and for the EQ-5D mean VAS score was 69,0.
Conclusions:
These results compared to the Danish knee artroplasty register
and other studies suggest that the CASPAR TKA method gives equal,
excellent clinical results up to 10-years compared to the conventional method.
