AI Article Synopsis
- Overweight and obesity heighten the risk of developing knee osteoarthritis, a leading cause of disability.
- Severe cases can be treated with knee arthroplasty, but overweight patients tend to have poorer outcomes than normal-weight individuals.
- Computer simulations indicated that excess weight increases stress on femoral bones and contact pressure during movement, suggesting that cementless total knee arthroplasty with thicker polyethylene inserts could improve outcomes for overweight patients.
Article Abstract
Overweight and obesity increase risks of knee osteoarthritis, which is a major cause of disability. Severe knee osteoarthritis can be treated by knee arthroplasty. Total knee arthroplasty has been used in overweight and obese patients; however, clinical reports showed that the outcome of this group of patients was not good as normal-weight patients. Two computer models were created in this paper to simulate the effect of excess loads on the distal femoral bone and contact pressures in total knee arthroplasty during a gait cycle. The numerical results showed increased stress in periprosthetic distal femoral bones and higher contact pressure on tibial polyethylene insert during the stance phase. Based on the computer simulation results and published research work, cementless total knee arthroplasty with thicker tibial polyethylene insert may be a better option for overweight patients.
