Straightening a Stiff Knee Under Anesthesia

California rates for HCPCS 27570

With the patient asleep and the muscles fully relaxed, the surgeon bends and straightens the knee firmly to break down scar tissue that has locked up its movement. No incision is made. It is used when a knee has stiffened after injury, surgery or a joint replacement and stretching alone has not restored the range.
