Patellar Arthritis

Patient Stories

I’m a runner for over 20 years and after I ran the 2011 NYC Half Marathon, I started feeling some discomfort in my right knee, but I did not put too much attention. I went to see an orthopedic MD in Astoria and after an MRI and x-rays, he told me that my days as a runner were over, and… Read more “Viviana Denig”

I just wanted to take a moment and share my story and wonderful experience with The Women’s Sports Medicine Center and Doctor Sabrina Strickland at Hospital for Special Surgery. As you can see, I am not “local” to NYC. It is an effort to come to Manhattan, but the effort it well worth it. I have had a lifetime of… Read more “Paulette Gangemi”

Since adolescence, I have had knee pain and subluxation and many knee surgeries. Knee pain was a part of my life for over twenty years, but it became increasingly worse to the point where I had episodes of significant swelling every other week. It began interfering with my work, my commute, and limited my activities with my family. I was… Read more “Maureen Suhr”

I had an amazing experience with at HSS. Dr Shubin Stein did my TTT (Tibia Tubrical Transfer) on both knees, each 6 months apart, and then screw removal. Both surgeries went way better than I could have imagined. Previously, I had crunching and significant pain especially with stairs. Now I never have pain and feel free to to whatever exercise… Read more “Kimberly Zastenchik”

Imagine your in a sports game. And all of a sudden your knees start hurting. You think it’s just from running and it’ll go away. For a few months it doesn’t go away. You tell your parents and go to a doctor. The first doctor says do physical therapy and you’ll be fine. You do the physical therapy while you… Read more “Taylor Dumond”

I am 27 years old. A few years ago my knee cap was on the left side of my knee and half of my cartilage was gone on the right side of my knee. So my doctor down here told me he could not do it and he sent me up to HSS see Dr. Shubin Stein. She looked at… Read more “Laura Carhart”

My left kneecap started dislocating and subluxating in early adolescence, when I was playing soccer and basketball regularly and also growing tall rather quickly (I wound up close to 5’8). Over the next 15 years, the condition was a constant in my life–I lived with the pain when my kneecap popped out of place a couple of times each year.… Read more “Seyward Darby”

Patellofemoral knee arthritis symptoms include pain, grinding, stiffness and often swelling in the front part of the knee that is typically worse when going up and down stairs, squatting, or rising from sitting to standing.

Patellofemoral arthritis is diagnosed when there is significant loss or damage of the cartilage between the patella (kneecap) and the trochlea (groove).The knee joint is composed of 3 parts. The patellofemoral compartment (the knee cap and its groove) and the medial and lateral tibiofemoral (inner and outer parts of the knee that you walk on).  If the medial and lateral compartments of the knee are affected (in addition to the knee cap), then the diagnosis is more likely generalized osteoarthritis of the knee.

People who develop patellofemoral arthritis generally are diagnosed with one of the following:

  • Post-instability arthritis, due to multiple dislocations or subluxations in the joint that results in cartilage damage.
  • Post-traumatic arthritis, due to a fall or other traumatic knee injury that results in cartilage damage and then progresses over time to arthritis
  • Malalignment or overload arthritis which is generally due to a misalignment of the patella that has been tracking incorrectly for a prolonged period resulting in wearing away of the cartilage on the outside of the kneecap and the groove, and
  • General osteoarthritis, a gradually progressive thinning of the cartilage related to “normal wear and tear” that is restricted to, or starts in, the patellofemoral compartment of the knee.

Treatments for Patellofemoral Arthritis

Non-Surgical Treatment

Treatment for patellofemoral arthritis starts with modifications in activity, such as limiting stairs, squats and lunges, and decreasing high impact sports.  Physical therapy is helpful to stretch and strengthen surrounding muscles; and use of non-steroidal anti-inflammatory drugs (NSAIDs) to relieve pain.

Steroid injections can help to reduce inflammation in patients with mild to moderate arthritis experiencing an acute flare-up of their condition (often associated with swelling). Viscosupplementation, is another good option. Viscosupplementation is a substance that mimics naturally occurring joint fluid. It can be injected into the joint to help lubricate and minimize friction and is often helpful in patients with mild to moderate arthritis. In patients who are overweight, weight loss can help reduce the amount of stress on the knee.

PRP and stem cell injections can also be useful in reducing inflammation if the Viscosupplementation injections haven't worked.
