About
The goal of this prospective, non-randomized, multicenter clinical trial is to determine whether robotic-assisted total knee arthroplasty performed with TSolution One® System is safe and effective for use as an alternative to the conventional manual techniques. Clinical and radiographic outcomes for robotic-assisted total knee arthroplasty performed with the TSolution One® System will be collected preoperatively, intraoperatively, and postoperatively up to a follow-up period of no less than 6 months and no more than 12 months. These outcomes will be compared to the ones reported in the literature for conventional manual techniques.
Full description
This clinical investigation will be conducted as a prospective, non-randomized, multicenter study. The primary objective of this study is to demonstrate that the TSolution One System is safe and effective for use as an alternative to manual planning and sawing/cutting techniques. The primary effectiveness objective of this study is to demonstrate that the TSolution One® System is effective for use as an alternative to manual planning and sawing/cutting techniques by comparing the rate of malalignment for mechanical axis greater than 3° at 3 months to the rate reported in the literature (i.e. 32%) and to demonstrate significant clinical benefit by reducing the number of malaligned patients by at least 50% (i.e. from 32% to ≤ 16%). The safety objective of this study is based on the rate of intraoperative and postoperative TKA complications, with a follow-up period of no less than 6 months and no more than 12 months, and to compare this rate to the rate reported in the literature. The secondary objective of this study is to summarize the distribution of improvements in patients' self-reported assessment of postoperative function and quality-of-life from baseline to a maximum of 12 months. Additionally, other preoperative planning alignment goals (e.g. Knee V-V Alignment; Femoral Joint Line Alignment Angle; Tibial Joint Line Alignment Angle; Tibial Slope Angle) will be compared to the post-operative alignment at 3 months.
Investigators will recruit subjects from patients in their practice who require unilateral total knee arthroplasty. Patients will be screened to identify eligible candidates based on the inclusion and exclusion criteria. A total of one hundred fifteen (115) patients will be enrolled in the study across the participating sites. All patients will sign an informed consent form prior to participating in the study.
Prior to undergoing the investigational procedure, the patients will complete baseline surveys of function and quality of life (Knee Society Score survey and the SF-12 Health Survey) and have baseline radiographs and a CT scan of the knee.
Each patient will then undergo robotic-assisted total knee arthroplasty with the TSolution One® System. The investigators will evaluate intra- and postoperative complications. Postoperative radiographs and a CT scan will be used to measure limb alignment using a standardized radiographic evaluation protocol. Each patient will complete a postoperative Knee Society Score survey and the SF-12 Health Survey to assess functional outcomes and quality-of-life following the investigational procedure.
