Patient Consent for Hip & Knee Arthroscopy

Arthroscopy or keyhole surgery is just a method of access to a joint. In this case the knee or the hip. There are many different pathologies and therefore procedures performed using this  method. Leading on from this, potential complications of surgery will depend on what specifically is done. This will be discussed individually with you the patient.

The method of arthroscopy does however lessen the overall risk of complications with specific reference to infection, blood loss and risk of nerve and vessel injury. These risks do still apply though, as do all other risks of surgery.

Any penetration of a joint with instruments, if not done carefully can result in cartilage injury. Also the action of entering the joint will cause inflammation and can result in excessive scar tissue formation within the joint leading to pain and stiffness (Arthrofibrosis). If this happens then a manipulation under anaesthetic with be required followed by in tensive physiotherapy in hospital. Sometimes repeat surgery is needed to release the scar tissue. Early movement within specified limits is essential.

Unique to Hip Arthroscopy is the  use of traction. Traction allows for subluxation of the femur head out of the socket to facilitate access to the joint. This traction acts like a tourniquet and will result in temporary nerve numbness that recovers well, mostly within a few hours. On occasion however, it may last longer.
