Joint Replacement

Osteoarthritis or OA is the most common cause of joint pain and stiffness. OA occurs with age, or in a joint that was previously injured or overused.   There are many conservative treatments for mild OA that may help relieve its painful symptoms.

  • Exercise or physical therapy
  • Bracing for support
  • Anti-inflammatory medication
  • Orthotics
  • Injection therapy
  • Viscosupplementation therapy

Hip Replacement

hip anatomyThe hip joint is the powerhouse that makes it possible to walk, run and jump.This joint is formed by the union of the top of the femur, the long thigh bone, and the side of the pelvis. The femur has a ball shaped protrusion at the top, which fits snugly into a socket shaped pocket in the pelvis. It is held in place by an intricate system of ligaments and muscles, which provides the locomotive power to move the leg freely in a full circle as well as side-to-side.

Keeping the two bone surfaces from painfully rubbing together is a thick pad of cartilage on both surfaces. The cartilage also acts as a shock
absorber keeping the bone surfaces from crushing together when moving. The cartilage is kept moist by a thin membrane, which provides a watery fluid to lubricate the joint.

The trend for hip replacement surgery is on the rise. The most commonreason for this surgery is arthritis including osteoarthritis, rheumatoid arthritis and traumatic arthritis. Childhood hip diseases can cause problems with the surface of the hip structure later in life even whenthe condition was successfully treated earlier.

Millions of active Americans are seeking help for hip pain because unlike earlier generations, they are not content with modifying or limiting their lives when there are new surgical options available.In the past, patients have used medication, exercise and lifestyle changes as a strategy to postpone surgery. However, when severe pain or joint damage begins to limit your daily activities, a joint replacement is your best option to regain functionality.

Knee Replacement

knee-anatomyThe knee is one of the most complex joints in the body because it is heavily responsible for both the horizontal and vertical motion in the body.

The knee consists of three primary parts:

  • Lower part of the thighbone (femur)
  • Upper end of the shinbone (tibia)
  • Kneecap (patella)

These three bones form a junction. The end of each bone is covered with a substance called articular cartilage. This articular cartilage is smooth, providing a surface along which the bones can easily move against each other. The thighbone and shinbone are held together with a series of ligaments, and the kneecap is placed in front of this junction for protection.

When all components are working in harmony, the knee is a remarkable feat of engineering. When disease or injury disrupts its operation, the resultant pain and muscle weakness can be debilitating. Unfortunately, the knee is prone to arthritis and other conditions that reduce its ability to move smoothly and painlessly. If a knee replacement is necessary, Drs. Lahey and Vinton have ample experience in total knee replacement.
