Clinical and Radiological outcomes in 3-D printing assisted
This study investigates whether three-dimensional (3D) printing-assisted revision TH/TKA could improve its clinical and radiological outcomes and assess the depth and breadth of research conducted on 3D printing-assisted revision total hip and knee arthroplasty.

Only studies that investigated 3D printing-assisted revision total hip and knee arthroplasty were included. The author, publication year, study design, number of patients, patients age, the time of follow-up, surgery category, Coleman score, clinical outcomes measured, clinical outcomes conclusion, radiological outcomes measured, and radiological outcomes conclusion were extracted and analyzed.

--10 articles were included in our review. 3 articles investigated the outcome of revision total knee arthroplasty, and 7 investigated the outcome of revision total hip arthroplasty. Two papers compared a 3D printing group with a control group, and the other 8 reported 3D printing treatment outcomes alone. 9 articles investigated the clinical outcomes of total hip/knee arthroplasty, and 8 studied the radiological outcomes of total hip/knee arthroplasty.

To summarize, 3D printing is being implemented in revision TKA. According to the current literature, 3D printing can help achieve satisfactory clinical and radiological outcomes.
