When a patient diagnosed with frozen shoulder disorder, fails to respond to any of the
non-surgical treatments, listed above, then surgery will be considered as an option.
The aim of performing surgery is to remove stiffness from the joint and
to stretch the connective tissues. This is done either by manipulation under anesthesia (MUA) or through shoulder arthroscopy.
MUA - This procedure is
performed by the Orthopedic Surgeon. Anesthesia is administrated and the Orthopedic Surgeon will manipulate the shoulder joint to move, causing the capsule
and scar tissue to either tear or stretch,
consequently releasing the stiffness and increasing the range of motion.
Surgical Capsular Release or Shoulder Arthroscopy - After anesthesia has been
administrated, the Orthopedic Surgeon will make 2 or 3 tiny, keyhole incisions into the afflicted shoulder. An arthroscope (camera measuring 3 and
half millimeter) is inserted into one of the incisions. The images from the camera are projected onto a computer screen. Through the other two incisions,
microsurgical instruments are inserted to surgically release the frozen shoulder.
Sometimes, the orthopedic surgeon may use both the manipulation and arthroscopy procedures
simultaneously, to get the maximum outcomes.
