It is planned to collect prospective and retrospective data from a continuous and exhaustive series of patients in a French center where Total Knee Arthroplasty with HLS prosthesis is performed routinely.~All patients treated with HLS KneeTec (cemented, non-cemented or hybrid versions) implant will be included. All eligible patients seen in consultation and who agree to participate in the study should be included, systematically and consecutively, since the initiation of the study.~Data will be collected retrospectively for HLS I, II, Evolution and Noetos® implants, and when prospectively for cementless, cemented and hybrid HLS KneeTec prosthesis.~Post-surgery visit data will be collected at 1-y , 3-y , 5-y, 10-y FU visits per protocol then up to the latest FU visit available.
The purpose of this study is to evaluate clinical performance and safety in total knee arthroplasty using HLS implants.
