The KineSpring System is associated with lower cost and increased QALYs. In comparison to current standard-of-care treatments, the KineSpring System has a favorable cost-utility ratio, making it an effective treatment option and a suitable cost-saving alternative. Assuming a treatment durability of 10 years, the cost-utility ratio of TKA, UKA, HTO, KineSpring System, and conservative treatments, compared to no treatment, are €4884 ± 323/QALYs, €4243 ± 280/QALYs, €4744 ± 313/QALYs, €3757 ± 1353/QALYs, and €10,575 ± 4414/QALYs, respectively. Assuming lifetime durability, cost-utility ratios of total knee arthroplasty (TKA), unicompartmental knee arthroplasty (UKA), high tibial osteotomy (HTO), KineSpring System, and conservative treatments, compared to no treatment, are €2348 ± 70/QALYs, €2040 ± 61/QALYs, €2281 ± 68/ QALY, €1669 ± 268/QALYs, and €11,688 ± 2185/QALYs, respectively. Cost-utility ratios were calculated assuming lifetime and 10-year durability. Cost-utility ratios were calculated using derived cost data and we calculated quality-adjusted life years (QALYs) gained for each method of treatment. Another important aspect of this case was that the femoral and tibial bases of the KineSpring System remained in situ, which simplified each phase of the revision procedure.We investigated the efficacy and cost effectiveness of the KineSpring System in the Spanish healthcare system, as compared to other standard treatments methods. A key finding of this case was that knee OA pain resolved with the KineSpring System, returned following explant of the absorber unit, and resolved again following implant of the new absorber. We performed a novel two-stage revision procedure where the absorber unit was removed in the first phase and a new absorber was placed 3 months later after the infection resolved. We report a case of a male patient who underwent implant with the KineSpring System for symptomatic knee OA but subsequently required revision due to local infection. The KineSpring ® System joint unloading implant is a unique device that reduces the load carried by the medial compartment of the knee joint by up to 13 kilograms during the stance phase of gait.
