Arthroscopic Surgeries

Dr. Yu continues to advance the use of arthroscopic surgery in hips, knees, shoulders and other joints. One example of Dr. Yu's keen interest in improving arthroscopic surgical outcomes is having been among the first in the fall of 2005 to begin performing anatomic Anterior Cruciate Ligament, ACL, reconstruction of the knee. 

Arthroscopy is the most common minimally invasive surgery performed in orthopedic. It can be used for the diagnosis and treatment of problems affecting the: hip, knee, shoulder, elbow, ankle, and wrist.

Arthroscopy literally means "to look within the joint". During the procedure, the surgeon makes a small incision and inserts the pencil-sized arthroscope into the problem joint. Fiber optics within the scope transmit images to a TV monitor. Because arthroscopy enables the doctor to clearly see the internal joint structures, it is useful for diagnosing joint problems. When arthroscopy is used in treatment, specialized surgical instruments are inserted through other small incisions to remove and/or repair damaged tissues.


Arthroscopic surgery is done under general anesthesia while patients are "asleep." It is an outpatient surgery and patients generally go home after the anesthesia wears off. If you have more pain than usual or require additional care, Dr. Yu may admit you for overnight pain control or observation.

Pain Reduction

Soft Tissue Injection: In addition to pain pills, Dr. Yu will inject analgesics into the surgical site at the end of surgery. 

Cryo-Pads: Circulating cooling pads will be added on top of your surgical dressing to reduce swelling and decrease pain. Cryo-Pads will not be used on diabetic patients. 

For Arthroscopic Shoulder Surgery: A scalene block may be administered by an anesthesiologist at the base of your neck to reduce pain from surgery. This will significantly reduce shoulder pain, thus reducing your narcotic use. The scalene block  will make you feels like you had a stroke as you may not feel your arm for 6 to 12 hours. Your pupils may also be dilated, causing slight vision problems. 

For Extended Arthroscopic Knee Surgery:  At the time of your surgery, you may receive injections administered by the anesthesiologist to the base of your thigh to reduce the pain from surgery. The femoral block may be left as an indwelling catheter attached to a pump for up to three days, automatically delivering analgesics to the nerve, thus reducing your narcotics use.
