A clinical study has been carried out on 434 posterior-stabilized knee prostheses (Optetrak; Exactech, Gainesville, Fla) implanted between 1995 and 2000 in a university general hospital by 23 surgeons. At a mean follow-up of 8.8 years, 297 knees in 249 patients were available for review. Average patient age at surgery was 71.8 years. Average body mass index was 28.8 kg/m(2). Mean flexion range was 108° .The average knee score (Hospital for Special Surgery) increased from 48 points preoperatively to 86 points (60-97 points) at the final review. Of the patients, 81% had an excellent or good result, 14.9% had a fair result, and 4.1% had a poor result. Using the Kaplan-Meier method, we obtained a 91.3% predicted implant survival at 12 years including septic and aseptic revision in the best-case scenario.

The purpose of this study was to assess mid-term survivorship following primary total knee arthroplasty (TKA) with Optetrak Logic components and identify the most common revision indications at a single institution. We identified a retrospective cohort of 7,941 Optetrak primary TKAs performed from January 2010 to December 2018. We reviewed the intraoperative findings of 369 TKAs that required revision TKA from January 2010 to December 2021 and the details of the revision implants used.

Knee complications and function were analyzed in patients with 2 different posterior-stabilized total knee arthroplasty (TKA) designs, Optetrak 913 and Insall-Burstein II. Three hundred Insall-Burstein II knees with mean follow-up of 8 years (range: 5-9 years) and 300 Optetrak knees with mean follow-up of 6 years (range: 5-7 years) were studied. Lateral retinacular release was performed in 30% of Insall-Burstein II patients and 16% of Optetrak patients (P = 0.
