Three decades of experience with unicompartmental knee arthroplasty: mistakes made and lessons learned

Unicompartmental arthroplasty results and survivorship will continue to improve with time. The future will refine patient selection and bring better surgical techniques and prosthetic designs. Improved polyethylene will increase longevity of the arthroplasty, and mobile-bearing articulations also may improve longevity by decreasing wear and allowing a metal-backed component with relatively thin polyethylene inserts for a conservative arthroplasty.
