Joint Replacement

At SOS our physicians are on the forefront of the leading edge technology when it comes to our joint replacement techniques. We offer a variety of techniques to relieve pain, maximize function and improve quality of life. We offer joint replacements for your shoulder, hip and knee. We also offer total joint revisions.


Why do I need a joint replacement?

Patients who need a joint replacement may experience:

  • Long term wear & tear in the joint

  • Inflammation

  • Pain

  • Swelling

  • Stiffness

  • Tissue Damage

When symptoms have not subsided from other treatment options such as physical therapy, injections and anti-inflammatories joint replacement surgery may be suggested by the physician. A joint replacement is done to improve the quality of life, decrease joint pain and improve joint function.

Hip Replacement

We offer both the Anterior Hip Replacement approach and the SUPERPATH Hip Replacement.

Anterior Hip Replacement

Using the anterior approach where the incision is made at the front of the hip allows the provider to spare major muscles, tendons and tissue.

Benefits include:

  • Faster and easier recovery

  • Minimal Post-op Pain

  • Fewer dislocations

  • No Surgical dislocation

  • No damage to major muscles

Deciding on the right Surgeon:

Dr. Matthew Seidel has over a decade of experience as an orthopedic surgeon and has performed hundreds of hip replacements using the anterior technique, choosing a physician who has gone through specialty training in the anterior approach is important to ensure you are in the best hands possible for your surgery. As with any surgery you want to make sure you are comfortable with your surgeon and they are knowledgeable. Dr. Seidel is recognized as an expert who trains other surgeons to perform the anterior approach.

SUPERPATH Hip Replacement:

The SUPERPATH is a less invasive total hip replacement technique where there is no surgical dislocation of the hip, sparing the tissue and aiming to get patients back on their feet within days (possibly hours). It is designed to reconstruct the hip without cutting, stretching or traumatizing muscles and tendons important to the function of the hip.

Why is not dislocating important?

By never surgically dislocating the hip, there is little trauma to the surrounding muscles and tendons. With SUPERPATH Hip Replacement, no muscles are cut during the procedure.

The Elimination of damage to important structures, patients typically have a shorter hospital stay and a number of patients walk the same day as their surgery.


  • Less Painful than traditional hip replacement

  • Smaller Incision

  • Faster Recovery

  • Shorter Hospital Stay

  • No Restrictions

  • Less blood loss during surgery

  • Patients often walk day of surgery

  • Less need for walker or cane

  • More natural feeling hip

  • Reduced dislocation risk

  • Faster return to full activity

Why Dr. Judd Cummings?

Dr. Cummings has successfully performed hundreds of hip replacement procedures helping patients live pain free and regain their active lifestyles. Over the past 5 years, SUPERPATH has emerged as the preferred technique for minimally invasive, rapid recover hip replacement. As a leading expert in SUPERPATH, Dr. Cummings travels the country educating and teaching other surgeons this tissue sparing procedure.

What about the “old fashion” posterior approach?

Major muscles are sliced open, possible permanent limp, large painful scar on your posterior, hip “pops” out of socket more easily and it takes longer before you can “run around and play”.

Knee Replacement

Personalized Options to Eliminate Knee pain and keep you moving.

If you're finding it hard to perform simple activities such as walking or climbing stairs and you are in pain while you're sitting or lying down resting, it may be time to consider a knee replacement. Knee replacement surgery is one of the most successful surgeries in terms of relieving pain and returning patients to better function allowing you to live a more active life free from knee pain.

What you need to know!

A knee replacement (knee arthroplasty) is essentially a “resurfacing” as only the surface of the bones are replaced.

Our Board Certified Fellowship Trained Orthopaedic Surgeons are the leading experts for knee replacements allowing patients to return to their everyday active lifestyles without pain. We offer the most advanced procedures allowing for a customized approach. This allows for faster recovery, shorter hospital stays, less pain after surgery, smaller incision / scars, and less blood loss during surgery.

Causes of Knee Pain:

The most common cause of knee pain is arthritis. Most knee pain is caused by one of three types of arthritis:

  • Osteoarthritis: age-related “wear & tear”
  • Rheumatoid Arthritis: Chronic inflammatory arthritis
  • Post-traumatic Arthritis: Follows a serious knee injury

When to consider knee replacement:

  • Severe stiffness or pain that affects every day life
  • Moderate to severe knee pain while resting
  • Chronic knee inflammation and swelling that does not improve with medication and / or rest
  • Knee deformity
  • Failure of improvement with other treatments including medications, injections, physical therapy and / or other surgeries.

Partial VS Total

The decision for a replacement should be decided between you, your family and your physician.

Partial: an alternative to total knee replacement for patients whose degeneration is limited to just one area of the knee. With a partial knee replacement more of the healthy bones, ligaments and cartilage are kept.

Total: When the entire knee is replaced with an artificial joint.

The Benefits of knee replacement

  • Alleviates stiffness, pain and swelling
  • Improved mobility
  • Improved quality of life

Types of Knee Replacements performed at Specialty Orthopaedic Surgery:

MAKOplasty: This is a partial knee arthroplasty using a Robotic Arm to assist in the surgery. With the MAKOplasty you need a CT scan of your knee joint, which is then used to create a 3D virtual model of your unique anatomy. This model is then loaded into the MAKO system software and used to create an individualized pre-operative plan.

Once in surgery the robotic arm is used to assist in performing your surgery based on the individualized pre-operative plan. If adjustments are needed the surgeon can make them during surgery as well. The robotic arm helps provide a more accurate placement and alignment of your implant.


  • Implant is less likely to wear and loosen

  • Bone & tissue sparing

  • Smaller incision

  • Minimal Scarring

  • Reduced blood loss during the procedure

  • Shorter hospital stay

  • Rapid recovery

  • More natural feeling knee

Prophecy Personalized Knee Replacement:

This is a total knee replacement technique that minimizes the risk of implant failure. The pre-operative navigation guide delivers an extremely accurate placement of your new knee. The knee is essentially a hinge and the hinge works best and lasts longest when it is lined up perfectly with your leg. Ideally, the knee is lined up with your hip and ankle. Traditional knee replacements are placed in an orientation that is average for everyone but probably fits no one perfectly. The prophecy system places your knee specifically for your height, length of your leg, width of your pelvis and size of your bones. This give you a superior outcome compared to an old-fashioned knee replacement.

Shoulder Replacement

Shoulder replacement is a highly technical surgery that should only be performed by a surgeon that has vast experience in this surgery.

Total Shoulder Replacement: A shoulder replacement is where the arthritic joint surfaces are replaced with a ball attached to a stem and a socket. This type of replacement replaces the ball and socket similar to the way they are in the body. The total shoulder replacement is utilized when all of the natural muscles and tendons around the shoulder are working well and there are no tears.

Reverse Shoulder Replacement: A reverse shoulder replacement is done when the rotator cuff is completely or mostly torn and is accompanied by severe arm weakness, cuff tear arthropathy [arthritis that sets in when the rotator cuff has not kept the ball in the socket] or when a previous shoulder replacement has failed. The Reverse shoulder replacement is where the artificial socket and ball are switched. This means that the ball is attached to the shoulder bone and the socket is attached to the upper arm bone allowing the patient to use the deltoid muscle instead of the torn rotator cuff to lift the arm.

Total Joint Revisions

A total joint revision is needed when the joint replacement is no longer functioning properly due to the artificial joint failing, is infected or if the patient had an unknown allergy to the metal in the replacement.

Reasons for a revision:

  • Implant loosens and is worn

  • Joint Infection

  • Instability

  • Stiffness

  • Fractures

  • Metal allergy

Symptoms/indications of replacement failure

  • Diminished stability

  • Reduced function

  • Increased Pain

  • Chronic swelling
