Minimally Invasive Surgery (MIS)

MIS Joint Replacement offers important advantages, requiring smaller incisions and potentially causing less trauma, shorter hospital stay, faster recovery and less scarring than traditional techniques.

Partial Knee Resurfacing

Partial knee resurfacing (PKR) is a surgical procedure for relieving arthritis in one compartment of the knee. With PKR, only the damaged surface of the knee joint is replaced, helping to minimize trauma to healthy bone and tissue.

Rotator Cuff Repair

A rotator cuff tear is a common cause of pain and disability among adults. A torn rotator cuff will weaken your shoulder. This means that many daily activities, like combing your hair or getting dressed, may become painful and difficult to do.

Minimally Invasive Surgery

Minimally invasive surgery (MIS) can offer many benefits over traditional open surgery, including a quicker recovery time, less pain, and less blood loss. Dr. McLennan treats a variety of orthopaedic conditions, using minimally invasive techniques whenever possible.

What is Minimally Invasive Surgery?

Minimally invasive surgery is a surgical technique that offers patients the same benefits of traditional open surgery, but with less pain and a shorter recovery time. Minimally invasive surgery disturbs fewer of the muscles and tendons surrounding the affected area, allowing for a more natural reconstruction and a quicker and easier recovery. Other benefits of minimally invasive surgery include smaller incisions, less pain, less scarring, and a shorter hospital stay as compared to open surgery.

What Are the Most Common Minimally Invasive Procedures?

Dr. McLennan treats a variety of orthopaedic conditions with minimally invasive surgery, but the most common minimally invasive procedures are hip and knee replacements.

Hip Replacement Surgery

During a traditional hip replacement procedure, the surgeon makes a single large incision, approximately 10 to 12 inches long, to access the joint. During a minimally invasive hip replacement, the surgeon will make one or two smaller incisions, usually three to six inches long. Because the incisions are smaller, Dr. McLennan can perform the procedure without having to cut or detach as many muscles and/or tendons as he would during a traditional hip replacement.

As with a traditional hip replacement, the damaged femoral head is removed and replaced with a metal ball-shaped component. The damaged cartilage within the socket is removed and replaced with a metal cup that is lined with plastic to allow the new joint to glide smoothly. However, the operating instruments used during a minimally invasive hip replacement differ from those used during a traditional hip replacement. They are specially designed to prepare the femur and socket and allow for proper placement of the implants.

Knee Replacement Surgery

Minimally invasive knee replacement surgery is very similar to traditional knee replacement. The same implants are used for both procedures. The main difference between the two procedures is that a surgeon performing a minimally invasive procedure uses special operating instruments to allow him to make smaller incisions than those needed for a traditional knee replacement.

During a knee replacement, the damaged ends of the femur and tibia are removed and replaced with metal components. A plastic spacer is then placed between the two metal components to allow for ease of movement. If needed, the kneecap may be resurfaced with a plastic component. Minimally invasive knee replacement techniques avoid or minimize damage to the quadriceps muscles in the front of the thigh, making recovery quicker and less painful.

Who Is a Candidate for Minimally Invasive Surgery?

Unlike traditional surgery, minimally invasive surgery is not suitable for all patients. Dr. McLennan will evaluate you to determine whether you are a candidate for minimally invasive surgery and will discuss your surgical options with you to determine the best course of action.

Generally, candidates for minimally invasive surgery are thinner, younger, and healthier than those who undergo traditional surgery. Patients who are overweight or have previously undergone a similar procedure are generally not candidates for minimally invasive surgery. Additionally, those who have severe deformity within the joint, are very muscular, or have a health condition that slows wound healing may run a higher risk of complications when undergoing minimally invasive surgery.
