Who Needs Joint Replacement Surgery?

The most common reason for joint replacement is degenerative arthritis, a condition caused by the gradual wear and tear of cartilage in the hip or knee.

If joint pain is limiting your mobility, work, or daily activities, our team can develop a personalized treatment plan to restore your function. We start with non-surgical options, such as:
• Medications
• Injection therapy
• Physical therapy

ONS also has a dedicated team of non-operative orthopedic specialists to help manage pain and delay or avoid surgery when possible. If these treatments are no longer effective, surgery may be the best option.

Types of Joint Replacement Surgery at ONS

We treat a wide range of people, from athletes with overuse injuries to adults who have been dealing with knee or hip pain for decades. Not everyone needs surgery to treat their injured hip, but for those who do, there are multiple options available, including various types and approaches as well as same-day outpatient joint replacement surgery.

Hip Replacement Surgery

Our surgeons remove the damaged ball and socket hip joint and reconstruct it with an artificial joint designed for durability and improved function. Your doctor will discuss if this is an appropriate treatment for your condition, and if you are a candidate for outpatient total hip replacement surgery. We perform:
• Total hip replacement
• Partial hip replacement
• Minimally invasive hip replacement
• Outpatient hip replacement for eligible patients
