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.

Orthopaedic Specialties of Dr. McLennan

Dr. McLennan treats a variety of Orthopaedic conditions of the shoulder, hip, and knee. He uses arthroscopic and minimally invasive techniques whenever possible to shorten recovery time and decrease pain.

Shoulder Specialties

Shoulder Arthroscopy: Arthroscopy can be used for several shoulder procedures, including rotator cuff repairs, removal of bone spurs, inflamed tissue, and ligament repairs. During an arthroscopic procedure, Dr. McLennan uses arthrosopic techniques ( a small camera to see inside the joint) to perform procedures through a much smaller incision, in contrast to open surgery. This results in more accurate repairs and shortened recovery times.

Shoulder Replacement: Arthritis in the shoulder can lead to pain and instability, severely effecting ones quality of life. If nonsurgical treatment fails to help, Dr. McLennan may consider shoulder replacement. Shoulder replacement surgery involves resurfacing the socket and ball.

Rotator Cuff Surgery: Injuries to the rotator cuff (supraspinatus and infraspinatus muscles and tendons) may require repair when there is delimitation, splitting, partial and complete tears. Frequently at surgery, other injuries to the ligaments, tendons, and cartilage covering the socket and ball may also require treatment. These areas sometimes are not obvious on MRI's because the arm is at rest.

Hip Specialties

Hip Replacement: Osteoarthritis can cause hip pain that severely effects ones quality of life. Hip replacement surgery can help to restore function in the hip, allowing the patient to return to normal activities. Hip replacement involves removing the damaged portions of the hip and replacing the ball and socket of the joint with prosthetic components that exactly match your normal anatomy, allowing immediate weight bearing.

Hip Revisions: Although hip replacements are overwhelmingly successful, implants at times can fail. Failure is uncommon, but when it does occur it may effect one or both components. Mechanisms are loosening, mal-position and rarely infection. When this does occur, one or both implants are re-placed. Hip replacements were first used in the 1960's and even with first generation techniques they where very successful, lasting 20+ years. Now with more sophisticated materials and techniques, we can expect significantly longer survival.

Knee Specialties

Knee Replacement: Arthritis in the knee can lead to progressive wear of all three compartments of the joint, cause pain, swelling, and instability. When conservative management fails and ones quality of life deteriorates, surgery may be necessary. The worn surfaces of the knee may require resurfacing, also known as replacement.

Partial Knee Resurfacing: When only one of the three areas of the knee wear out, (the inside, outside or under surface of the knee cap) the damaged portions of the knee can be resurfaced or replaced. The implants are smaller than those used for a total knee replacement. This minimizes trauma to the healthy portions of the knee, often resulting in less pain following the operation.

Knee Revisions: Knee resurfacing or replacement began in the 1970's. Even with first generation techniques, the majority of these implants lasted 15 years plus. However, when injuries, loosening, or infections develop, these implants may require revision.

Knee Arthroscopy: Arthroscopy allows Dr. McLennan to view the structures of the knee with a tiny camera that is inserted through small incisions around the knee. Arthroscopy can be used to remove, repair, or trim torn cartilage, reconstruct torn ligaments (such as the ACL), remove loose bone fragments, inflamed bursa's, synovium (lining), transplant cartilage or tissues, and release adhesions. As a minimally invasive procedure, arthroscopy generally results in a shorter recovery time than open surgery.

ACL Reconstruction: A tear to the anterior cruciate ligament, or ACL, is one of the most common knee injuries. Dr. McLennan arthroscopicaly reconstructs the torn ACL using allograft tendons or tissues from donors. This can be done “all inside” versus multiple incisions.

Other Orthopaedic Specialties

Minimally Invasive Surgery: Minimally invasive surgical techniques allow the surgeon to perform surgery through a smaller incision than what is needed for traditional open surgery. These techniques are designed to facilitate a quicker recovery time. Minimally invasive techniques have been developed to treat numerous conditions, including the shoulder, hip, and knee.

Trauma Care: When the extremities sustain trauma resulting in severe soft tissue injuries and fracture, non-surgical methods frequently allow recovery. However, when conservative methods, such as casts, splints, and braces fail, operative intervention is necessary. In these cases, a small rod-like device (intramedullary nail) can be inserted into the hollow center of the bone, acting as an internal splint. External fixation can also be used to hold broken bones in place using plates, screws, wires and special sutures. There are fractures that are in several pieces or with associated soft issue injuries-closed or opened, that may necessitate external fixation.

Carpal Tunnel: Nonsurgical treatment for carpal tunnel often includes resting, taking anti-inflammatory medications, and wearing a brace or splint to immobilize the wrist. Surgical treatment for carpal tunnel involves releasing the carpal ligament by arthroscopic or minimally invasive techniques (less than 1/2 inch or 12.5 mm) at the wrist. This procedure takes 15-20 minutes.

Sports Medicine: Sports medicine involves the treatment and prevention of injuries in athletes and their return competition. These modalities are geared to participants of all ages and sex. Sports medicine is designed to correct and rehabilitate athletic injuries as quickly and safely as possible. This may entail aggressive use of medications, physical and occupational therapy, the use of trainers and coaches, bracing, orthotics, appropriate shoes, gradient compression wear and surgery.
