Joint Replacement Service

Diagnosis and Treatment

The biggest help we give our patients is to start with the correct diagnosis.

Millions of individuals across the country and world suffer from debilitating joint pain. Joint pain often involves:

  • Osteoarthritis (OA) – bone damage caused by injuries both new and old, or simple wear and tear. Learn more about osteoarthritis.
  • Rheumatoid arthritis (RA) – systemic, inflammatory disease that may cause significant joint pain. RA can happen at any age and can show a variety of symptoms, some of which can be highly debilitating. Learn more about rheumatoid arthritis.
We’re making great strides in hip and knee replacement.

Whether searching for a solution for osteoarthritis or rheumatoid arthritis, our team will provide patients with the latest treatment options, a continuity of care found only at HSS, and a group of the most experienced surgeons in the world.

Where appropriate, we may recommend no surgery at all, instead opting for a regimen that may include medications, pain management techniques, and physical therapy.

For those patients who do require hip or knee replacement, our surgeons will work with you to select the most appropriate options based on your needs and medical history. Options include:

Types of Hip Replacement

  • Total Hip Replacement: In a traditional total hip replacement – still considered the “gold standard” approach by many – muscles around the hip joint are exposed, damaged areas of the hip ball (femoral head) and socket (acetabulum) are removed, and the artificial joint is inserted. Where appropriate, we use minimally invasive techniques that allow for smaller incisions. Typically, the incision will be made in the back of the hip (posterior approach); in some cases, it may be made in the front or side of the hip (anterior approach). Learn more about total hip replacement.

  • Hip Resurfacing: Unlike a traditional hip replacement, hip resurfacing does not remove the hip ball; instead, the damaged ball is reshaped and capped with a metal prosthesis. The damaged socket is fitted with a metal prosthesis similar to a traditional hip replacement. Learn more about hip resurfacing.

  • Hip Revision: A hip revision is a re-operation of a total hip replacement due to a mechanical or biological failure that may develop – though relatively uncommon – over the lifespan of the prosthesis. Learn more about hip revision.

Types of Knee Replacement

  • Total Knee Replacement: Like total hip, total knee replacement is considered the “gold standard” approach for the treatment of extensive knee arthritis. In total knee replacement, the damaged areas of the knee are exposed and removed; the remaining bone is prepared to receive the artificial knee joint, and then the prosthesis is inserted. Where appropriate, we use minimally invasive techniques that allow for smaller incisions. Learn more about total knee replacement.

  • Partial Knee Replacement: In partial knee replacement, only one section – or “compartment” – of the knee is replaced, instead of the entire joint. Partial knee replacement may be appropriate for some patients in which the arthritis is confined to a single compartment. Your surgeon will determine whether you may be an appropriate candidate. Learn more about partial knee replacement.

  • Knee Revision: Just as with hip implants, knee implants that fail for mechanical or biological reasons over the lifespan of the device may require revision. Learn more about knee revision.

For both knee and hip replacement procedures, some surgeons at HSS may use a computer-navigated robotic arm to facilitate the placement and alignment of the implant.

After the hip and knee, the shoulder is the third most common joint affected by arthritis. For some patients suffering from shoulder arthritis, total shoulder replacement may be an appropriate option.
