Could you be treating your patients with a Partial Knee Replacement?

Research shows that 47.6% of knee replacement patients are actually candidates for partial knee arthroplasty (PKA)4 and  after one year, a randomized, controlled study showed that significantly more partial knee patients would have the operation again compared to total knee patients5.

Furthermore, Liddle, AD. et al., found that surgeons utilizing PKR for under 20% of their annual knee replacements experienced an increase in their revision rate.6
