About total joint replacement

When someone suffers from arthritis related to degenerative, congenital, inflammatory, or traumatic causes, it may be hard for them to perform even simple tasks such as walking or climbing stairs. They may even feel pain when sitting or lying down. A painful joint can often prevent patients from enjoying daily activities such as walking, shopping, traveling and recreational sports, leading to a sedentary life. If medications, changing everyday activities and the use of walking aids are not helpful, joint replacement surgery may be an option.

Joint replacement implants are metal and plastic coverings for raw, arthritic bone ends. They replace cartilage that has worn away over the years. Total joint replacement surgery can help relieve pain and get patients back to enjoying normal everyday activities. Replacement implants are made from materials such as titanium or other metal alloys, ceramics, plastics or other newer substances. The goal is to eliminate bone-on-bone friction to create a new, smoothly functioning joint that will last for years.

In a total hip replacement, the surgeon removes the arthritic ball of the thighbone (femur) and the damaged, inflamed cartilage in the hip socket. The ball is replaced by a metal or ceramic ball attached to a stem, placed into the thighbone. A metal cup relines the socket, creating a new, smooth and durable joint.

In a total knee replacement, the arthritic rough surfaces at the end of the thighbone and shinbone are replaced with polished metal inlays. A space-age plastic cushion separates the inlays, acting as an artificial cartilage. The kneecap (patella) is preserved and, if worn, is resurfaced with a similar plastic cushion.

Before surgery

The first visit

During your first visit, one of our surgeons will perform a thorough examination and may ask for further imaging and laboratory tests to provide the best diagnostic information for your treatment plan. This is key to a successful outcome. While at the office, you may also meet with the surgical coordinator, who can help with scheduling and logistics, as well as the patient educator and the physician assistant.

Presurgical testing

You'll have to contact the department directly to schedule a presurgical testing appointment approximately 21 days prior to surgery. Presurgical testing includes a physical examination and further laboratory tests if needed. If you are not feeling well for any reason, this should be brought to the attention of the staff. The hospital also requires a medical clearance from your primary care physician and/or specialist, such as a cardiologist. These should be obtained prior to the date of presurgical testing.


When preparing for joint replacement surgery, as with any surgery, there are some preoperative considerations to keep in mind that can help optimize your results and recovery:

  • Exercise—Our bodies tend to heal and regain function faster when they are in good physical and cardiovascular condition.
  • Medication—Before the surgery, discuss medications you may currently be taking with your physician. Some may need to be temporarily discontinued until after the surgery. This determination can be most appropriately made by your physician or orthopedist.
  • Discharge planning—As with any surgery, you should be sure to discuss discharge planning with your physician beforehand. The discharge plan may include instructions on care of the incision, pain medications, activities, special exercises, and other home care instructions.
  • Rehabilitation—People who have received a total joint replacement can still lead functional, active lifestyles. One major component of many rehabilitation programs is exercise—to restore function, mobility, and strength to the affected joint and surrounding muscles. Discuss with your physician what an appropriate postoperative rehabilitation program should include.

Surgical options

After all the clinical data is reviewed, your doctor will decide on the optimal surgical procedure for the joint replacement. Different patients require different surgical options, so your treatment plan is tailored to your specific needs and will be presented in great detail so you understand what is involved.

Surgical options include:

  • Minimally invasive techniques—The center's surgeons are skilled in using smaller incisions to perform repairs to the knee and hip.
  • Revision surgery—Prosthetic joints used in joint replacement surgery have a finite life span. When that time comes, revision surgery replaces previous worn out joint replacements. These revision surgeries are even more complex than the original surgery and demand the highest level of surgical skills that orthopedic surgeons, such as those at our center, can provide.
  • Anterior approach to hip replacement surgery—The anterior approach means that the surgeon reaches the hip by going between two muscles, rather than by removing and then reattaching a muscle. This can allow for less postoperative pain and faster rehabilitation and recovery.

The surgical experience

The hospital will call you the day prior to surgery to remind you of the time to arrive at the hospital for the procedure. On the day of surgery, after checking in to the hospital, your records and all consent forms will be reviewed by the nursing staff and you will be brought to the presurgical holding area.

The surgeon will personally mark the specific site of surgery and the anesthesiologist will again review the options for anesthesia. The majority of joint replacement surgery is performed under regional anesthesia, however, in some instances general anesthesia is preferred. The final decision is made by you and the anesthesiologist. For those patients undergoing regional or epidural anesthesia, additional sedation can be given during the surgery.

For routine joint replacements, the actual surgical procedure generally takes less than one hour. Immediately after the surgery, you will be taken to the Post Anesthesia Care Unit (PACU) where you will be monitored for several hours before being brought to the hospital room. Your family will be notified once surgery is complete and you have been transferred to the PACU.

Recognized for quality care

Several of our hospitals have received the prestigious Joint Commission's Disease-Specific Care Certification for healthcare quality in knee and hip replacement surgery.


Rehabilitation following joint replacement surgery starts in the hospital within just a few hours of the procedure. Physical therapists and rehabilitation specialists will prescribe exercises to help you get out of bed and regain strength as safely and rapidly as possible. Most patients spend two to four days on the orthopedic surgical floor and are able to walk with a cane or walker and use the stairs independently when leaving the hospital.

Some patients may be admitted for sub-acute care for five to seven days, however most are discharged to home care and do their rehabilitation in their own homes. Depending on your physical needs, support at home, and insurance coverage, you may be encouraged to continue therapy in an outpatient rehabilitation center. The center's team will follow up on your progress.

Patients and their families have several options for rehabilitation care, and prior to surgery the treatment team will help you decide which of the following options is best:

  • Sub-acute inpatient rehabilitation—Sub-acute inpatient rehabilitation provides continued therapies and skilled nursing care in an inpatient setting. Therapy intensity will vary (one to three hours per day) depending on a patient’s needs and ability. Lengths of stay will vary and patients may be released to either outpatient or home-based treatment. Northwell Health Rehabilitation Network offers a variety of care options in multiple locations.
  • At-home rehabilitationNorthwell Health At Home provides comprehensive, specialized joint replacement home care services with an emphasis on rehabilitation, wellness and recovery in the home setting. Physical therapy will begin within 24 hours of discharge, ensuring a seamless transition from the inpatient facility to the home. Therapy intensity and duration of services will vary depending on the patient's needs, abilities, and insurance coverage. A rehabilitation nurse coordinator will serve as a liaison between the patient's physician and all home care disciplines, enhancing communication and coordination of care.
