“…16 We found that the BMD recorded at the first postoperative examination did not predict relative change in BMD at 5 years. This is in accordance with the findings by Soininvaara et al 5 and Regnér et al, 17 who did not observe any association between initial BMD in the proximal tibia and subsequent BMD changes. However, Muller et al 18 reported that high mineral content at operation correlated significantly with periprosthetic bone loss 5 years after total hip replacement in young patients with cementless custom-made femoral implants.…”

After total knee replacement (TKR) the bone mineral density (BMD) decreases in the proximal tibia. Our aim was to evaluate if changes in constraint of the cemented AMK TKR (DePuy, Johnson & Johnson, Leeds, UK) had any effect on postoperative bone remodeling in the proximal tibia. We used dual-energy X-ray absorptiometry in 43-53 knees to record changes in BMD in three regions of interest around the tibial component up to 5 years after operation with the AMK (DePuy) TKR. The knees had been randomly allocated to receive a flat or a concave tibial insert with retention of the posterior cruciate ligament when preoperative deformity was less severe, and either a concave or a posterior-stabilized (PS) insert with resection of the posterior cruciate ligament when deformity was more pronounced. All designs were associated with loss of BMD in the proximal tibia. The mean bone loss varied from 5 to 23% depending on the region of interest. There were no statistically significant differences between the groups, and the alteration of tibial insert constraint did not influence the bone remodeling. However, low precision values may have impaired the detection of differences. ß

“…This nding was demonstrated by detailed BMD analysis by high-solution DXA in selected ROIs, and revealed 21 bone loss in the distal femur and 25 in the tibia, compared with normal annual Only a few studies have reported the ef cacy of measuring BMD around the knee after TKA following the development of high-solution DXA 12 . Soininvaara et al [5][6][7] measured periprosthetic tibial BMD, but these data did not cover both the tibial and femoral sides, and involved only short-term follow-up and a cemented TKA. Petersen et al 13 looked at cementless TKA, but the BMD measurement was by dual photon absorptiometry rather than DXA, and only the tibial side was measured.…”

“…It uses two X-ray beams of different energy levels to scan the region of interest and measure attenuation as the beam passes through the bone 4 . Soininvaara et al [5][6][7] qualitatively assessed bone around the knee components after TKA using DXA. However, these studies evaluated only the femoral, or tibial, side, and an analysis of the stress shielding and remodeling of bone around the knee following TKA is needed.…”

: Bony atrophy around the components following total knee arthroplasty TKA is often observed by radiography. To investigate the underlying cause of this incidence, we sought to quantitatively evaluate postoperative bone changes around the total knee components using dual-energy X-ray absorptiometry DXA over time. A retrospective study was conducted to compare bone mineral density BMD around the components in 22 patients pre-operatively and at 1, 3, 6, 12, and 24 months after cementless TKA for the treatment of osteoarthritis. In the coronal view, the medial tibia showed that a signi cant decrease in BMD at 12 months compared with 1 month after surgery P 0.05 , while the sagittal view showed that a signi cant decrease in BMD only at the anterior femoral condyle at 24 months compared with 1 month postoperatively P 0.05 . TKA improved the leg alignment and load-bearing axis in all patients, but we found that BMD tended to decrease on the medial side of the tibia and the anterior femoral condyle area over time following surgery. Our results suggest that recreating proper valgus alignment of the knee joint provides physiological balancing and condition. A larger prospective study is warranted.
