Golf and Total Knee Replacement – Videofluoroscopy Study
Playing Golf after total knee replacement surgery can be an oftentimes-discussed topic. The present videofluoroscopy study has the goal to analyse the influence of implant design as well as foot position on the kinematics and loading of the total knee replacement during the golf swing.
Keywords: Golf, Total Knee Replacement, Movement Analysis, Videofluoroscopy, Biomechanics
Golf is a widely popular sport and as the majority of players are over the age of 50, playing after total knee replacement surgery can be an oftentimes-discussed topic. The return to play rate >94% after total knee replacement is encouraging, however the majority of players with a TKA report pain during or after play. In vivo assessments of tibiofemoral joint forces revealed contact forces up to 440% BW in the lead leg and also demonstrated more than 10° of external femoral rotation in patients with total knee replacement. Total knee replacements exist with either mobile or fixed bearings, but it remains unclear if the bearing type does have an influence on tibiofemoral kinematics as well as loading of the bone-implant interface during activities involving large axial rotation in combination with an almost fully extended leg, as can be seen during the golf swing. Theoretically, it can be assumed that the mobile bearing design would provide potentially more room for rotation while reducing the stresses on the implant. Therefore, the objective of the overall project is to analyse the influence of the bearing type as well as the foot position of the lead leg on the kinematics and loading of the total knee replacement during the golf swing. Results of the study could lead to recommendations of the choice of total knee replacement for golf playing patients as well as on the optimal foot position of the lead leg in reducing resulting loading of the total knee replacement.
The present study is the first part of the project and includes an experimental study on the 3D kinematics of the total knee replacement by means of videofluoroscopy, whole body kinematics by means of skin markers and ground reaction forces during the golf swing in golfers with two different total knee arthroplasty designs.
