Abstract
ObjectiveTo investigate the effect of accelerometry-based navigation (ABN) on early clinical outcomes after TKA. Methods71 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. ResultsAt 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). ConclusionEarly KOOS, JR scores are improved with ABN for TKA.
