Over four decades ago, physicians at HSS pioneered the first artificial human knee replacement – just one milestone in more than 150 years of specialized care. Today, surgeons in the Adult Reconstruction and Joint Replacement (ARJR) Service continue to lead the field in both innovation and in the number of hip and knee replacement surgeries performed each year.
Our physicians are constantly developing new surgical techniques, using smaller instruments and smaller implants, to facilitate hip and knee replacements. These procedures are opening doors for our patients – to get them pain-free and back to doing what they love to do.
Knowledge gained through depth of experience:
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:
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:
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.
Your Pathway to Recovery
Contacting us is the first step. We are here to help.
At HSS, we offer total hip and knee replacement as an outpatient procedure. If your physician has said you are a candidate for unilateral or unicompartmental hip or knee replacement, our ambulatory joint replacement surgery program may be right for you. It allows select patients to undergo knee or hip replacement surgery in our state-of-the-art surgery center and go home on the same day. Patients participating in this program can begin their recovery process in the comfort of their homes.
If you can answer yes to all of the below questions, you may be able to have outpatient joint replacement surgery.
All patients who express interest in the ambulatory joint replacement surgery program are evaluated by both the orthopedic surgeon and our multidisciplinary team.

As the #1 orthopedic hospital in the nation and the leader in surgical volumes for many orthopedic specialties, patients expect superior outcomes from treatment at HSS. Our Adult Reconstruction and Joint Replacement (ARJR) Service delivers on these expectations through our specialization and relentless focus on quality.
Many patients seek treatment with the ARJR Service because they are in pain or have lost the ability to function at a desired level. The overwhelming majority of patients show dramatic improvement after either hip or knee surgery from one of our ARJR surgeons.

It all starts with an accurate diagnosis. Many patients come to us with questions about what to do next. Surgery benefits many patients with orthopedic conditions, but it's not right for all patients. The ARJR doctors at HSS are experts in guiding patients to the appropriate choice of treatment.
At HSS, we pride ourselves on our low incidence of unexpected problems after surgery. HSS has a significantly lower Surgical Site Infection (SSI) rate than the state average, as determined by the New York State Department of Health.
Research continues to demonstrate that the surgeons and hospitals that get the best results from total joint replacement surgeries tend to be the ones who perform those surgeries most often. Higher volume is correlated with lower rates of mortality, infection, pneumonia, and other complications. HSS performs substantially more total joint replacement surgeries than other top national hospitals. At HSS, there are 25 ARJR surgeons who perform more than 10,000 surgeries each year.
'Likelihood to Recommend' is a key indicator of satisfaction with the outcome of treatment. HSS patients demonstrate a higher Likelihood to Recommend than the patients at other leading orthopedic hospitals.
