Abstract:
Objective:To evaluate the clinical outcomes of total knee arthroplasty (TKA) assisted by 3D printing in the treatment of traumatic osteoarthritis secondary to severe knee deformity after old tibial plateau fracture.Methods:A retrospective study was conducted to analyze the clinical data of the 18 patients who had been treated for traumatic osteoarthritis secondary to severe knee deformity after old tibial plateau fracture at Department of Orthopaedics, The People's Hospital of Guizhou Province from March 2015 to June 2017. The cohort included 7 males and 11 females, with a mean age of (64.0±7.7) years. The left knee was affected in 12 cases and the right in 6 ones. The injury was caused by a traffic accident in 12 cases, by a fall from heights in 4 cases, and by a heavy object in 2 cases. The time from fracture to TKA was (5.9±2.8) years. All patients underwent TKA assisted by 3D printing after admission. Knee range of motion (ROM), Hospital for Special Surgery (HSS) knee score, and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were compared between preoperation and postoperative 6 months. Complications during the follow-up period were also recorded.Results:All the 18 patients completed a 6-month follow-up. At 6 months after operation, the knee ROM increased significantly from preoperative 85.1°±2.9° to 125.3°±1.3°, the HSS knee score increased significantly from preoperative (39.6±1.4) points to (75.8±1.8) points, and the WOMAC score decreased significantly from preoperative (49.3±1.0) points to (8.3±0.7) points in the 18 patients ( P<0.05). One patient experienced poor wound healing 1 week after operation, and 3 patients developed low-lying patella postoperatively. No such complications as prosthesis loosening, infection, or joint stiffness were reported during the follow-up period. Conclusion:For patients with traumatic osteoarthritis secondary to severe deformity following old tibial plateau fracture, TKA assisted by 3D printing can significantly improve their knee ROM and restore their limb function, but lead to no serious complications.
