My 14 yr old daughter has had knee pain for a couple of years, Dr's have said muscles around her knee joint needed strengthening and she has been going to physical therapy. the 1st therapist she went to said the range of motion in her hip/knee was minimal and had her do a stretching routine. I decided not to continue with the therapy since she could do these stretches at home. To my regret she didn't continue with the stretches and about a year later her knee/hip pain worsened. X-ray's were taken. Radioligist and orthopedic said x-ray looked fine. Orthopedic prescribed physical therapy. During therapy the knee pain has gone away but the therapist has conducted range of motion exercises in her hips and discovered during an exercise where my daughter is lying on her back and the therapist brings either knee up and across her chest, she has serious pain in her hip joint area. The therapist has recommended a orthopedic hip specialist will fix her problem. does anyone have an idea what the specialist might determine what issues my daughter may have with her hips?
