I have a client who experiences a 'burning' and 'tearing' sensation everytime she bends her right knee. Palpating the area while she flexes / extends her knee, I feel a vibration and something like a grinding / groaning. She has a family history of terrible knee conditions, her mother and grandmother have both had total knee replacements. She says she's just waiting till she inevitably has to get one.
Unfortunately she cannot bend her knee in any fashion without the sensation; No high box squats, sumo deadlifts, leg presses, ball squats, side band walks nothing. This is making trying to think of lower body exercises for her interesting. When I ask her where in the knee she feels the pain she says she doesn't really know, which is a little frustrating.
She has no plans to see a doctor about it, and I don't want to take the risk of having her do motions that aggravate her knee.
I'm presently having her do a lot of upper body, but to try and get SOME lower body I have her doing various stiff-leg single leg exercises with bands and stiff-leg deadlift. Any other ideas for exercises or ANY idea what her problem could be from my extremely vague description would be greatly appreciated.
