Total Knee Arthroplasty: Follow-up
Updated: Apr 14, 2009
Outcome and Prognosis
Most patients seem satisfied with their knee replacements, and if pain relief is the main indication for surgery, this indeed should be the case. Satisfactory knee function is usually restored following total knee arthroplasty, and the majority of patients are able to return to low-impact sporting activity.15,16 Long-term studies confirm satisfactory functional scores and show a 91-96% prosthesis survival rate at 14-15 years of follow-up. No difference appears to exist between PCL-retaining and PCL-substituting designs. Cementless designs do not have the same length of follow-up, but studies at 10-12 years report a 95% prosthesis survival rate.3,7,8,17,18
Future and Controversies
Cemented total knee replacements will remain the criterion standard for total knee arthroplasty, but use of uncemented designs with bioactive surfaces (eg, hydroxyapatite) are showing promising midterm results (see Image 17).19

Research into mobile bearing knee replacements continues. Such prostheses appear to demonstrate an attractive way of overcoming the constraint-versus-conformity conflict inherent in any artificial knee replacement.
