Our user aksed: "I have never had any issues with my knees- thank goodness. I'm a snow skier, so I need my knees in tact! My knees are 100% A couple of weeks ago, a muffled popping/snapping sound started in my right knee when I squat down. There's no pain, discomfort, swelling or bruising of any kind. I didn't fall down or slip or anything either. Just started making this sound. I started thinking what could have caused this? I started doing lunges in the gym recently- holding the weights in my hands and taking deep steps forward- making sure my knee is behind my foot when I step forward. This is the only thing I can think of that I've changed in my routine that might have caused this- Can lunges cause this to happen? Will it go away with time now that I've stopped doing the lunges since there's no pain, or should I have this looked at?"
Ask a PT Response: "Popping/snapping sounds are not uncommon even in healthy knees. Deeper lunges will put additional stress on your knees which could result in your joint or tendons at your joint to release trapped air. If you don't perform deep lunges do you still experience the sounds? Also wondering how old you are? Older patients might have some degenerative changes at the knee which may contribute to the sounds you describe. Since you are not experiencing pain or edema, it is totally up to you for peace of mind as far as getting it looked at right now. If it does continue to persist, than it may not be a bad idea to have it looked at. Could be other contributing factors such as deficits with flexibility, joint mobility, strength, biomechanics, etc. which a PT would be able to determine."
