Abstract
OBJECTIVE: To investigate the effect of accelerometry-based navigation (ABN) on early clinical outcomes after TKA. METHODS: 71 TKAs were performed via ABN and 37 TKAs via standard instrumentation (STD). Patients were assessed at the second post-operative visit to determine early KOOS, JR scores. RESULTS: At average 2.7 months, mean KOOS, JR in the ABN group was 68.5 (range 34.2-100) compared to 62.5 (range 20.9-84.6) in the STD group (p = 0.045). Tourniquet time averaged 65.2min (range 51-79min) in STD group, compared with 70.7min (range 53-108min) in ABN group (p = 0.029). CONCLUSION: Early KOOS, JR scores are improved with ABN for TKA.
