Knee and hips joints are especially vulnerable to deterioration due to repeatedly being injured, arthritis or simple wear and tear. As living tissue, bones need copious amounts of oxygen-rich blood to remain healthy and continue repairing themselves (ossification). When joint damage or disease restricts blood flow, the joint may weaken and disintegrate, eventually requiring the services of a joint replacement surgeon in New York City.
A replacement joint for a failing hip or knee is called a prosthesis. Made of metal, plastic compounds or both, a prosthesis may be cemented in place so existing joint bones eventually absorb the prosthesis. If you are older and less active, your joint replacement surgeon in NYC may decide to cement the prosthesis. Alternately, if you are younger, more active and have healthy bones, your orthopedic surgeon will probably not cement the prosthesis in place.
For a total knee replacement, your Jersey City joint replacement surgeon will use large implants designed to resurface degraded ends of your tibia and femur. When just one side of a knee is damaged, your surgeon may opt for a unicompartmental knee replacement that resurfaces only that side.
For a total hip replacement, your joint replacement surgeon will replace your hip joint’s ball and socket with a metal prosthesis equipped with a polyethylene spacer between the ball and socket. Stainless steel and titanium are typically used to make hip replacement prosthetics. Implants are secured to bone by cementing the prosthesis or by press-fitting it into place.
Only your joint replacement surgeon in NYC can determine whether you are a candidate for a joint replacement procedure. Through x-rays, arthroscopy and/or tissue sampling, your orthopedic doctor will either develop a program of medication, rehabilitative exercise and physical therapy or recommend total joint replacement.
Causes of painful, stiff knees and hips include osteoarthritis, rheumatoid arthritis, post-traumatic arthritis (repetitive injuries) or advanced age/wear and tear. Osteoarthritis is the most common joint disease precipitating your Staten Island joint replacement surgeon to recommend a hip or knee replacement. Primarily affecting joint cartilage, osteoarthritis erodes cartilage so that joint bones scrape together, causing pain, inflammation, swelling and reduced joint motion. Bone spurs developing on the edges of the knee or hip joint may disintegrate and allow bits of bone to disperse within the joint space. This leads to increased pain and even more damage to the joint.
Made of durable, high-quality metal, plastic or both, your new joint is called a prosthesis, and it may or may not be cemented in place. Protheses that are cemented in place promote osseointegration, or the ability for real bone to fuse with the joint replacement. Implementation of a cemented prosthesis is more often used in older people who are less active or have diminished bone density. Uncemented prostheses are more applicable for younger, active patients exhibiting good bone quality.
Recovery from joint replacement surgery can be as short as several weeks or as long as several months, depending on your age, health and type of joint replacement. Since joint replacements typically lasts around 15 years, younger people may need their damaged joint replace more than one time.
