Two-year results of KJD compared with HTO and TKA 67 4 As for secondary outcomes, the total KOOS (Figure 2) was significantly improved at 2 years for all 4 groups as well (KJD TKA Δ29; TKA Δ43; KJD HTO Δ22; HTO Δ30; all p< 0.001). All 3 subscales of the WOMAC and 5 subscales of the KOOS as well as the VAS pain score, the EQ-5D, the SF-36 PCS, and the ICOAP showed similar positive trends, while only the SF-36 MCS showed almost no change compared to baseline (Table 3). Figure 2 : Total Knee injury and Osteoarthritis Outcome Score (KOOS). (A) KOOS score over 2 years for the subgroups indicated for total knee arthroplasty (TKA) and treated with knee joint distraction (KJD TKA ) or TKA, represented as mean ± standard error of the mean (SEM). (B) Two-year change in KOOS score for individual TKA-indicated patients (markers) and the subgroups (mean ± SEM, dashes). (C) Total KOOS score over 2 years for the subgroups indicated for high tibial osteotomy (HTO) and treated with KJD (KJD HTO ) or HTO, represented as mean ± SEM. (D) Two-year change in KOOS score for individual HTO-indicated patients (markers) and the subgroups (mean ± SEM, dashes). The p- values above subgroups indicate significant 2-year changes while the p- values between subgroups indicate the differences between each 2 groups.
