Impact of knee implant on DEXA measures. Data are presented as means ± 95CI for bone mineral density (BMD, g/cm2) of the legs and total body (A & D) with corresponding T-scores calculated for each measure (C & E). Regional limb comparison (A & B): CONTROL, limb with no implant present; TKA, limb with TKA implant assessed using standard iDXA software analysis; TKA-MAC, limb with TKA implant following manual artifact correction. Total body comparison (D & E) Total body, total body BMD with implant included assessed suing standard iDXA software analysis; Non-TKA Side Only, BMD assessed from the lateral side of the body with no implant; Total Body – MAC, total body BMD analyzed following manual artifact removal. Individual patient data are shown for those classified as normal, osteopenic (T < −1), or osteoporotic (T < −2.5) regionally (E) and for the total body across each analysis comparison (F).
