How Much Does Implant Design Affect Patient Outcomes?

Orthopedics This Week reports on the findings of an HSS study published in The Bone and Joint Journal which examined 4,135 patients who have received a total knee replacement (TKA) using common knee implant brands, to access the impact of implant design on patient-reported outcomes. Patients were evaluated preoperatively using the Knee Injury and Osteoarthritis Outcome Score (KOOS), Lower Extremity Activity Scale (LEAS), and 12-Item Short-Form-Health Survey questionnaire (SF-12). Two years post-surgery, researchers found no clinically significant differences in the change of KOOS score from baseline to two-year follow-up between the groups.

Study co-author Douglas E. Padgett, MD, Associate Surgeon-in-Chief and Deputy Medical Director at HSS, cited, “The main observation is that most modern-day knee implants are well designed and if proper surgical technique is utilized, there is very little difference in outcome. As such, surgeons and administrators can use this information as a point of reference in implant price negotiations. There appears to be very little justification for ‘premium pricing’ based upon our data.”
