3d Printing Of Knee Models To Decrease Or Time And Reduce Revisional Surgery In Total Knee Arthroplasty (Tka), Lauren Schlegel, John Paul Prodoehl, Matthew Chadwick, Chris Li, Katelyn Koons, Jeffrey Henstenburg, Md Jan 2020

3d Printing Of Knee Models To Decrease Or Time And Reduce Revisional Surgery In Total Knee Arthroplasty (Tka), Lauren Schlegel, John Paul Prodoehl, Matthew Chadwick, Chris Li, Katelyn Koons, Jeffrey Henstenburg, Md

Phase 1

Project Background: Osteophytes are a common problem, affecting 2% of the United States population. For many elderly people, these osteophytes will cause them to seek medical attention. Due to the 2-D nature of MRIs and CT scans, it can be difficult to gain a complete understanding of the complicated soft tissue structures surrounding the joint when performing a Total Knee Arthroplasty(TKA). Without proper removal of osteophytes and correct soft tissue balancing, there is an increased rate of revisional surgery. By utilizing a 3-D model preoperatively and within the OR, surgeons can visualize various aspects of the knee to determine what …

Phase 1

Project Background: In the United States, total knee arthroplasty (TKA) is the most performed orthopaedic operation. Among the 700,00 patients who received TKA, 21-25% underwent revision due to knee instability. Proper stability of a TKA depends on soft tissue balance for proper alignment in flexion and extension, and improper soft tissue modification is the primary cause of early implant failure. Soft tissue balancing can be complicated by presence of osteophytes on the distal femur or proximal tibia, which may require removal. The three-dimensional structure of osteophytes is often difficult to visualize with imaging, which could cause incomplete removal. Utilizing 3D …

Phase 1

Project Background: In the US alone, total knee arthroplasty is the most common performed orthopedic surgery, with over 700,000 cases per year.1 Overall, 21-25% underwent revision due to instability.2 The stability of a TKA depends largely on soft tissue balance for proper alignment in flexion and extension. Soft tissue balancing in TKA depends on posterior femoral condylar osteophytes, which prevent full extension of the knee and increase tension posteriorly. Pre-operative soft tissue visualization is difficult and this leaves an increased chance for implant failure and revision surgery. Having a 3D model of the bone spur before and during the surgery …

Phase 1

Project Background: In the United States, 2% of the population will experience bone spurs, which will not resolve on their own.1 Of people over 60 who experience a bone spur, 40% will require medical attention.2 The soft tissue visualization appears to be difficult with imaging, leaving increased chance of poor balancing of the knee replacement. Osteophyte structure continues to be difficult to visualize in a 3D way and without their proper removal, can lead to increased rate of revision surgery. Having a 3D model of the bone spur may decrease risk of complication and enhance soft tissue modification …

Phase 1

Background: In the United States, total knee arthroplasty (TKA) is the most common performed orthopedic surgery, with over 700,000 cases per year. Overall, 21-25% underwent revision due to instability. Incorrect soft tissue balancing during the procedure can lead to improper alignment, flexion, and extension. Visualization of osteophytes in a 3D manner prior to removal is difficult and poses significant risks for improper balancing on TKA. The purpose of the study is to determine whether the utilization of 3D osteophyte models is beneficial to Orthopaedic surgeons in the course of care, specifically with regard to improving outcomes, decreasing complication rates, and …
