Tons of S&V this summer, averaged 6 sets a week plus light hitting of 6 hours/week. Since 3 weeks ago both knees are getting bad, pain just below the knee cap, hurts the most when trying to stop forward momentum. I am quite sure this is caused by the split step after serve. age 36. Is this a common problem for s&v players? maybe it's a myth that one should play more S&V while getting old. The side to side moves along the baseline didn't give me this much knee pain before. Or is there something wrong in my split step. I went back to some McEnroe and Henman clips and seems even though they split step they don't appear to slow down the forward movement much at all, hence not putting too much pressure on the knees. Hardcourts obviously is a major factor, there is no give in every stop and go. Maybe it's time to do exclusively clay.
