Potential biomechanical risk factors on developing lead knee osteoarthritis in the golf swing.
Potential biomechanical risk factors on developing lead knee osteoarthritis in the golf swing. Scientific reports Kim, S. E., Pham, N. S., Park, J. H., Ladd, A., Lee, J. 2022; 12 (1): 22653Abstract
The load on the lead knee joint during a golf swing is greater than that observed during gait. However, current evidence regarding golf swing biomechanics for risks associated with knee osteoarthritis (OA) is limited. Therefore, this study investigated golf swing styles associated with knee adduction and abduction moments, which are considered to be crucial loading regions of the medial and lateral compartments of knee OA, respectively. Thirteen professional male golfers performed five shots using a 5-iron club, and their swings were recorded using a motion capture system with two force platforms for the feet. A regression analysis was performed to calculate the correlation coefficients between the peak knee adduction and abduction moments of the lead leg and varus/valgus angle, toe-out angle, stance width, weight transfer, and shoulder sway. Swinging with a narrower stance width at address (r?=??-?0.62, p?=?0.02) with more weight shift (r?=?0.66, p?=?0.014) and shoulder sway (r?=?0.79, p?=?0.001) towards the target during the downswing were associated with a higher peak knee adduction of the lead leg, whereas a greater valgus angle at address (r?=?0.60, p?=?0.03) was associated with a higher peak knee abduction of the lead leg. Based on these findings, we anticipate future research to support postural changes, particularly a wider stance width and restricted shoulder sway for golfers who are classified to be at high risk of developing medial compartment knee OA, as well as a lower valgus (tibial medial tilt) angle at address for those classified to be at high risk of developing lateral compartment knee OA.
