“…Surgical technique and postoperative management are described in detail in a previous article presenting the clinical outcome and radiographic evaluation of the same series. 35 Preoperatively, 36 patients had a mean (SD) varus deformity of 14.3 (7.0) degrees. In those patients, immediately after the operation, varus deformity was corrected almost down to zero (mean [SD], 1.4 [3.5] degrees).…”

Background: Peri-implant osteolysis is one of the major complications related to total ankle replacement. The aim of this study was to investigate the short- to midterm incidence of peri-implant osteolysis using computed tomography (CT) as imaging method for the Trabecular Metal Total Ankle (TMTA) implant representing a novel total ankle replacement (TAR) implant design regarding material and surgical technique. Methods: In total, 104 consecutive patients who had a primary TMTA replacement between March 2013 and October 2017 were included in the study. The radiographic evaluation included weightbearing anteroposterior and lateral views at baseline and after 3, 6, and every 12 months postoperatively. A helical CT was undertaken preoperatively and of the 80 patients available to follow up at least 12 months postoperatively, with average time interval between the TAR operation and the latest CT of 39 (range, 12-85) months. Results: Eight of 80 patients had altogether 11 osteolytic lesions around the components on CT images. Seven lesions were found in tibia, 3 in talus, and 1 in distal fibula. Four of the tibial lesions were situated in the medial malleolus and were not in contact with the prosthesis component. The sizes of the osteolytic lesions ranged between 7 and 20 mm, and the average volume of the lesions was 689 mm3. Conclusion: We conclude that the risk of peri-implant osteolysis with the TMTA implant is minimal in short to midterm. The anatomic configuration, unique material, and surgical technique may all contribute to the TMTA implant having a low rate of peri-implant osteolysis. Level of Evidence: Level IV, case series.

“…A newly designed porous Ta-based total ankle prosthesis was approved by the Food and Drug Administration in 2012 and marketed by Zimmer Biomet Inc. [ 164 , 165 ]. Combined with the use of porous Ta-based ankle prosthesis in TAA, promising prognosis can be foreseeable in terms of pain relief and functional improvement in the short-term, even without supplementation with cement augmentation, due to the fact that the stability of tibial and talar components mainly depends on bony interlocking between the porous Ta base and the host bone [ 164 , 165 , 166 , 167 , 168 , 169 , 170 ]. Moreover, the pattern of porous Ta bases of the two components resembles that of the subchondral bone of tibia and talus and can distribute loading stress rationally and diminish the occurrence of peri-implant osteolysis, which often resulted in aseptic loosening of the implants [ 165 , 171 ].…”

Porous tantalum (Ta) is a promising biomaterial and has been applied in orthopedics and dentistry for nearly two decades. The high porosity and interconnected pore structure of porous Ta promise fine bone ingrowth and new bone formation within the inner space, which further guarantee rapid osteointegration and bone–implant stability in the long term. Porous Ta has high wettability and surface energy that can facilitate adherence, proliferation and mineralization of osteoblasts. Meanwhile, the low elastic modulus and high friction coefficient of porous Ta allow it to effectively avoid the stress shield effect, minimize marginal bone loss and ensure primary stability. Accordingly, the satisfactory clinical application of porous Ta-based implants or prostheses is mainly derived from its excellent biological and mechanical properties. With the advent of additive manufacturing, personalized porous Ta-based implants or prostheses have shown their clinical value in the treatment of individual patients who need specially designed implants or prosthesis. In addition, many modification methods have been introduced to enhance the bioactivity and antibacterial property of porous Ta with promising in vitro and in vivo research results. In any case, choosing suitable patients is of great importance to guarantee surgical success after porous Ta insertion.
