Abstract Background This study is to describe the design and surgical techniques of three- dimensional-printed porous implants for proximal giant cell tumors of bone and evaluate the short-term clinical outcomes. Methods From December 2016 to April 2020, 8 patients with giant cell tumor of bone in the proximal tibia underwent intralesional curettage of the tumor and reconstruction with bone grafting and three-dimensional-printed porous implant. Detailed anatomy data were measured, including the size of lesion and thickness of the subchondral bone. Prostheses were custom-made for each patient by our team. All patients were evaluated regularly and short-term clinical outcomes were recorded. Results The mean follow-up period was 26 months. According to the different defect sizes, the mean size of the plate and mean length of strut were 35 × 35 mm and 20 mm, respectively. The mean affected subchondral bone percentage was 31.5%. The average preoperative and postoperative thickness of the subchondral bone was 2.1 mm and 11.1 mm, respectively. There was no wound infection, skin necrosis, peroneal nerve injury, or other surgical related complications. No degeneration of the knee joint was found. Osseointegration was observed in all patients. The MSTS improved from an average of 12 preoperatively to 28 postoperatively. Conclusion The application of three-dimensional-printed printed porous prosthesis combined autograft could supply enough mechanical support and enhance bone ingrowth. The design and operation management lead to satisfactory subchondral bone reconstruction.

Giant cell tumor (GCT) merupakan tumor destruktif tulang yang muncul di antara dekade kedua dan keempat, lokasi predileksi umumnya pada epifisis tulang panjang. Pemilihan tatalaksana operasi sangat penting dan masih menjadi perdebatan. Sebagaimana masih beragamnya pilihan tindakan pembedahan. Klasifikasi Campanacci dapat digunakan sebagai acuan untuk panduan tatalaksana. Pada kasus ini kami melaporkan seorang wanita, usia 18 tahun dengan diagnosa giant cell tumor pada proximal tibia dextra dengan Campanacci grade III. Pasien telah menjalani operasi limb salvage tahap pertama berupa eksisi luas pada proximal tibia dextra dan knee arthrodesis. Setelah 4 bulan dilakukan operasi limb salvage tahap kedua yaitu knee arthroplasty dengan megaprosthesis. Untuk mencegah komplikasi implant expose, dilakukan muscular flap dan split thickness skin grafting (STSG). Setelah dilakukan evaluasi selama 4 bulan, klinis pasien baik, pasien dapat berjalan alat bantu dan tanpa nyeri, tidak ada komplikasi pada luka operasi dan fiksasi implan baik. Kesimpulan yang didapatkan bahwa limb salvage surgery pada giant cell tumor proximal tibia dapat dilakukan dengan tindakan rekonstruksi dua tahap. Teknik muscular flap dan split thickness skin grafting (STSG) dapat digunakan untuk mencegah terjadinya implant expose.

Abstract Background To evaluate the effect of reconstruction and repair, using a mini-plate and bone graft for HIV -positive patients with giant cell tumor of long bone. Methods We conducted a retrospective analysis of 12 HIV positive patients with giant cell tumor of long bone. A non-HIV-positive cohort of patients, matched for age, sex, and disease type, was selected as the control group. From June 2012 to August 2020, curettage by ultrasonic scalpel was performed in all patients, combined with min- plate and bone graft treatment. All patients were followed- up for 18 to 60 months. Limb function was evaluated, using the MSTS93 scoring system, and any examples of postoperative recurrence, distant metastasis, complications, MSTS93 score, and fracture prognosis were recorded. Results The mean age of HIV group was 43.5 years. The ratio of men to women was 11: 1. In all cases the histopathological diagnosis was clear, except the patients with primary malignant giant cell tumor of bone, including five, three, two, and two cases in the proximal tibia, distal femur, distal tibia, and talus, respectively. Following their surgery, all patients were followed up with an average of 31.24 ± 11.84 months. No local recurrence or pulmonary metastases were observed. Post-surgery, all the 12 patients showed good bone morphologic repair and reconstruction, good bone healing, good joint function, and no pathological fractures around their lesion. In the HIV group, one case of giant cell tumor in the proximal tibia showed mild articular surface collapse and mild valgus deformity of the knee joint but retained good joint function. The MSTS scores of excellent or good in the two groups comprised 83.3%, thus, there was no significant difference between them (P > 0.05). Compared with preoperatively, the MSTS scores in the HIV group were significantly improved, ranging from 7 to 11 points preoperatively to 24 to 27 points postoperatively; this difference was statistically significant (P < 0.05). Conclusion Reconstruction and repair, using a mini-plate and bone graft for HIV -positive patients with giant cell tumor of long bone can achieve satisfactory results. The mini- plate requires little space and is flexible during reconstruction and fixation, significantly reducing complications such as surgical site infection, as well as preserving joint function and avoiding amputation; therefore, it is a safe and effective treatment method.
