Abstract
To better study hip and knee replacement, 50 eligible hip and knee patients from March 2020 to April 2021 were selected. A 1 : 1 scale solid model was printed with CT thin-layer scanning data assisted by 3D printing technology to evaluate the ankle function of patients six months after surgery. The results showed that the 3D rapid prototyping time of the 1 : 1 fracture model in 50 patients was 3-4 hours. The operation time was 70–90 min, and the average operation time was 80 min. The actual application in operation was consistent with that in the simulation of the 3D printing model, after surgery, and there was no infection of incision soft tissue or loss of reduction in all 50 patients. CT thin-layer scan data aided 3D printing technology can help clinical hip and knee replacement simulation and planning, improving surgery's accuracy and safety.
Highlights
Hip and knee replacement is a procedure to solve moderate-tosevere knee osteoarthritis and has a high success rate
Alazri et al [12] performed hip and knee replacement in 15 patients with preoperative planning assisted by an individualized osteotomy guide and conventional hip and knee replacement in 15 patients in the control group. e results showed that using the personalized osteotomy guide plate reduced the operation time and blood loss during and after the operation, which proved that the perioperative effect of three-dimensional assisted hip and knee arthroplasty is better than traditional methods
To study the application of 3D printing technology assisted computed tomography (CT) thin-slice scan data in treating hip and knee joint replacement, 50 patients were studied before surgery
Summary
Hip and knee replacement is a procedure to solve moderate-tosevere knee osteoarthritis and has a high success rate It mainly relaxes the soft tissue and bone tissue of the knee joint through the balance of the joint space, corrects the mechanical axis of the lower limbs, rebuilds the joint stability, relieves the symptoms of the patient, reduces the time in bed, achieves normal early activities, and restores the knee limbs [1]. E results showed that using the personalized osteotomy guide plate reduced the operation time and blood loss during and after the operation, which proved that the perioperative effect of three-dimensional assisted hip and knee arthroplasty is better than traditional methods. E results showed that the mean operative time and mean blood loss in the navigation template group were statistically significantly lower than those in the conventional group With this novel individualized navigation template, the operation is simplified and accurate, with good lower extremity lines, femoral anterior inclination, posterior tibial inclination, and knee space. Each hip and knee replacement is completed in about 45 minutes
