### input:
I had a fall in January . Tore my ACL and meniscus and sprained my LCL. I have a bone spur. MRI showed bursitis and osteoarthritis. I had no pain in my knee or difficulty walking prior to fall. I am 67 years old. I also have a complete rupture of the rotator cuff, from the fall. I have pain in my arm and knee. A muscle in my thigh has been numb since the fall. The numb area is about 3 inches wide and 6 inches long. The top of my knee cap is also numb. Last night I found a lump the size of a pea in my knee. It moves around. What could this be?

### output:

Hi, thank you for providing the brief history of you. As you are 67, there is a possibility of degenerative changes in the knee joint leading to wear and tear of the soft tissues and bone. Also, due to ACL injury, meniscus injury, and LCL injury you may face pain and difficulty in walking. Also, due to fall there might be pinching of lumbar nerve leading to sensory deficits in the lower limbs. Rotator cuff injury also needs an attention. As per you symptoms and other things I will advise you to undergo physical therapy and by this the pain can be reduced and so the inflammation. Post this rehabilitation of the knee and shoulder is advised followed by the Strengthening of the spinal Muscles. Most cases in my clinical practice responds well to physical therapy. As an important note, that ACL and menisci injury are graded according to the physiological discontinuity and the treatment is planned accordingly. RegardsJay In Chat Doctor.
