Abstract:
A total of 6 patients were treated with surface knee joint prosthesis combined with 3D-printed customized bionic tibial block for reconstruction of bone defect after giant cell tumor (GCT) in proximal tibia (1 male and 5 females, aged 50, 40, 68, 53, 35, 42, respectively). 3 patients with primary and 3 patients with recurrence of GCT. After resection of the tumor, the bone defect was filled with 3D-printed block combined with surface knee prosthesis, the surrounding ligaments were reconstructed with microporous structure and artificial mesh. All cases were followed up for 60, 90, 60, 60, 75, and 50 months, respectively. During the follow-up, there was no local recurrence, no radiolucent lines around prosthesis, and no signs of loosening. The clinical scores of the American Knee Society Score (KSS) were 87, 92, 85, 90, 95 and 78. The functional scores were 70, 100, 70, 100, 100 and 80 respectively. Musculoskeletal Tumor Society Score (MSTS) were 27, 28, 26, 26, 26, 27, respectively. Surface knee prosthesis combined with bionic block can effectively fill the bone defect after resection of GCT in proximal tibia, achieve anatomical and functional reconstruction of knee joint.
