Joint Replacement

Your joints are the areas where bone meets bone. Over time, the cushiony parts that keep the bones from rubbing together may wear away due to arthritis, injury or simply living life. This friction can cause pain, swelling and difficulty with movement.

Joint replacement may be an option when other methods of pain relief and mobility, such as medication and physical therapy, are unsuccessful.

If you're experiencing lack of movement or flexibility, or pain associated with the joints, you may wish to consult with a specialist.

The orthopaedic team at Main Line Health offers the most advanced techniques available for joint replacement, including minimally invasive procedures when possible.

What to know about joint replacement surgery

Types of joint replacement surgeries

Any joints in the body may be replaced but most commonly are the hip and knee. Joint replacement is a surgery that involves resurfacing or smoothing of the joints and cutting away of cartilage so that a prosthetic joint made of plastic, metal or a combination of both can be implanted and rejoined to existing bone and cartilage. As the area heals, new bone, cartilage and blood vessels form to increase blood flow to the area, relieve pain and enhance mobility.

Most joint replacements last 10 to 15 years depending on the type of material used and the activity level and individual needs of the patient.

When you need knee surgery or hip surgery

If surgery is right for you, you'll be in good hands. The multidisciplinary team at Main Line Health, including Main Line Health doctors and independent providers, is made up of some of the best hip replacement doctors and knee replacement surgeons in the Philadelphia region. Working closely with orthopaedic experts, your hip and knee navigator will guide you through every step of the hip and knee replacement process — from educational classes before surgery to on-site physical therapy while you 're in the hospital to recovering soundly at home or in a rehabilitation hospital. 

The joint replacement program is offered at our four hospital locations: Lankenau Medical Center (Wynnewood), Bryn Mawr Hospital, Paoli Hospital, and Riddle Hospital (Media).
