Hello Sir, My mother had injury in her right knee 2 months back. Basically, she got cut in her knee with deep wound, I got her treatment with the doctor, it only required 9 stitches at the wound and the docctor told me that it was just minor injury but it had not affected any damage to he tendant. Now, after two months the wound has cured but there appears slight swelling in her muscles and sever pain in her knee joint . kindly advise any further suggestion. Does it requires MRI scanning since the X-rays are showing normal. Thank you.
