Joint Replacement Surgery 

Joint replacement surgery involves removing a damaged joint and replacing it with a new one. A joint is where two or more bones come together, like the knee, hip, and shoulder. Sometimes the surgeon will not remove the whole joint, but will do a partial joint replacement.

Your doctor may suggest joint replacement to improve your quality of life. Joints most commonly replaced are hips and knees. Other joints may also be replaced like shoulders, fingers, ankles, and elbows. Replacing a joint can relieve pain and help with mobility and reduce pain. 

Anterior Supine Intermuscular (ASI) Hip Replacement Technique


Many options exist for hip replacement. Minimally invasive total hip replacement. ASI (Anterior Supine Intermuscular) hip replacement technique is a minimally invasive hip replacement that involves more than just a shorter incision. Modern minimally invasive techniques also focus on the way surgeons gain access to the hip joint. The goal is to minimize muscle and tendon disruption, making surgery less traumatic for patients, allowing for shorter hospital stays and quicker recoveries.

Computer Assisted Knee Replacement Procedures

With the use of special computers and imaging technology, orthopedic surgeons can confirm proper alignment of knee replacement implants. This computer-assisted navigation technology is especially helpful with patients who are severely overweight or have knee deformity because that can increase the difficulty of the procedure.

A computer-assisted knee replacement procedure begins with the surgeon placing several small transmitters on the patient's leg. An infrared camera is used to track the movement of the transmitters via a computer that analyzes the positions and creates an anatomical drawing of the knee. Using this real-time graphic display, the surgeon makes cuts in the bone to ensure proper alignment on the mechanical axis for the implant. The implant is then secured with bone cement, tested to ensure proper alignment, and the incision is closed with stitches. 

Partial Knee Replacement

In partial knee replacement, only the damaged compartment is replaced with a metal and plastic implant while the healthy cartilage and bone in the rest of the knee is left in place. Prior to the procedure, the doctor examines the knee, tries to identify the location of the pain, and tests the knee for range of motion and ligament quality. Imaging tests, such as x-rays and magnetic resonance imaging (MRI), may be done to see the pattern of arthritis or better assess the cartilage.

In a minimally invasive partial knee replacement procedure, an incision is made to allow for insertion of the knee replacement. The short length of the incision and less-invasive nature of the procedure may cause less discomfort, swelling and blood loss for patients, as well as a shorter stay in the hospital and less rehabilitation compared to conventional surgery. Patients may also be able to return to work earlier. 


Arthroscopy uses a small fiberoptic scope inserted through a small incision in the skin to see inside a joint. It is primarily a diagnostic tool, allowing surgeons to view joint problems without major surgery. Depending on the problem found, surgeons may use small tools inserted through additional incisions to repair the damage, such as a torn meniscus or a torn ligament that fails to heal naturally. Using arthroscopy, for example, a surgeon may reattach the torn ends of a ligament or reconstruct the ligaments by using a piece (graft) of healthy ligament from the patient or from a cadaver.

Because arthroscopy uses tiny incisions, it results in less trauma, swelling, and scar tissue than conventional surgery, which in turn decreases hospitalization and rehabilitation times. Problems can be diagnosed earlier and treated without serious health risks or more invasive procedures. Furthermore, because injuries are often addressed at an earlier stage, operations are more likely to be successful.
