a, c Pre-OP SPECT-CT images from a patient (f, 46 year, SPECT-CT: 5 months pre-implantation) with beginning knee OA and b, d corresponding post-op imaging (14 months post-implantation) exemplifying the effect from the examined load absorber (b, d: metal artifact labeled by arrow). Patient showing a significant decrease in bone turnover after implantation at the level of the left tibia plateau (ACmax, pre = 309.2 kBq/ml, [SUVmax = 77.5] and ACmax, post = 99.0 kBq/ml, [SUVmax = 31.7]). Accumulation patterns from bone turnover (pre/post) were windowed identically
