I have a 45 year old client who has pain in his left knee when kneeling on the floor. He says it is like kneeling on a stone. He started weight training at the tender age of 13. Also, when in a squat position, his knee makes a noise that I can only describe as a snapping. He has had this for a long time and said there is no pain, but it is very loud and sounds like it could be ligament. Please could you let me know if you have any suggestions as to what could be going on with his knee?
Snapping sounds occurring in the knee during squats are usually not a cause for alarm, as long as there is no pain involved with it. I actually have personal experience with this as I tore both of my anterior cruciate ligaments while playing basketball. After I rehabbed both knees and returned to my full activities, including playing basketball and performing squats, my knees would and still do make snapping sounds sometimes. My doctor told me these snaps are normal, and the sounds I hear are just the joint realigning itself.
However, if any pain or discomfort begins to occur during exercise, your client should get checked out by a doctor. The doctor can do tests to check the stability of the knee and the integrity of the ligaments as well as taking X-rays or performing an MRI. As far as the soreness on the knee when kneeling is concerned, it depends on how long it has been happening. If it is fairly recent, such as within the last few weeks, the soreness might go away in time with adequate rest and icing the knee before and after exercise. If the soreness has been present for a long time, then it might be a chronic condition your client will have to live with or seek treatment for from a doctor or physical therapist. You could have your client kneel on a pillow, rolled up towel or exercise mat when he has to kneel in order to ease the pain.
