Despite more than a decade of use, there are currently no comprehensive reviews summarising clinical results with the Profix Total Knee System in primary total knee arthroplasty. Searching the PubMed and Google Scholar databases revealed 17 potentially relevant Profix manuscripts. After author review and exclusion of studies not meeting predetermined variables, 8 manuscripts were selected. Knee Society data were provided in all 8 and implant survival data in 4. Data for 987 patients (1152 knees) were available. The overall estimated implant survival was 98.6% at 5 years and 94.2% at 10 years with revision for any reason as an endpoint, and 100% at both time points with radiographic loosening as an endpoint. Mean/median preoperative Knee Society knee scores improved from 39.2/24.7 at baseline, to 91.4/92.1 at the last postoperative follow-up visit. Good medium-to long-term clinical results can be expected with the Profix in primary total knee arthroplasty.
