Partial knee menisectomy is a very common surgery that involves removing the torn part of the meniscus. The meniscus is a natural shock absorber for the knee. In fact, in America alone, we perform about 700,000 of these surgeries per year, making it one of the most common orthopedic surgeries. While most patients think they’re getting a meniscus repair procedure, the truth is, 96% of these surgeries just remove a piece of the shock absorber, leaving your knee less protected.

There have been many high-quality research studies over the past decade or more that were designed to answer the specific question, “Is surgery necessary for a torn meniscus?” What did they show? All three large studies showed that meniscus surgery was not effective or no better than just physical therapy.

We offer innovative non-surgical procedures that may help decrease pain and improve knee function and mobility without the need for surgery.

Meniscus surgery is traumatic and carries associated risks. Even successful surgeries require months of painful rehab to regain strength and mobility. After surgery, most patients will be on crutches, wear a brace, or some combination of both for several weeks before returning back to normal activity. The recovery time and rehabilitation period may be extended up to six weeks with a knee brace or crutches.

Keep in mind that there may even be some complications associated with meniscus surgery, prolonging the recovery period even more. This includes complications with anesthesia, such as respiratory or cardiac malfunction, infections, and injury to nerves and blood vessels, fracture, weakness, stiffness or instability of the joint, inability to repair the meniscus, repeated rupture of the meniscus, or the need for additional surgeries.

Can you ever truly recover from parts of your knee meniscus being removed surgically? In the long run, almost all meniscus surgeries accelerate degeneration that leads to osteoarthritis and exacerbate the biomechanical problems that initially led to the need for the surgery.

Meniscus tears are like wrinkles; they are unavoidable. Some of us get more of them at a young age and some of us don’t get a lot of them until we’re older. The meniscus gets small tears as we age and as the knee joint begins to wear out. For example, in middle-aged and elderly patients, taking an MRI of patients with no knee pain and those with ongoing knee pain will reveal that both groups have about the same amount of meniscus tears. If these things usually don’t cause pain, why are we operating on them? If our surgeries are no better than fake surgeries, why are we placing all of these patients at the risk of surgical complications?

Recent research shows that some of the most popular orthopedic knee surgeries, including meniscectomies, have no benefit and are not more effective than placebo or sham surgery. But can a meniscus tear heal on its own when left untreated? Non-surgical treatments for meniscus tears for healing on their own include physical therapy, rest, ice, compression and elevation. Interventional orthopedics also provides a non-surgical injection alternative that may prove beneficial in reducing pain and improving function.

Have you been told that invasive surgery is your only option to fix your torn ACL? Getting your ACL replaced permanently alters the mechanics of the knee joint. You have other options when it comes to treating your ACL injury. In fact, about 70% of all ACL tears that currently get surgery could have been treated with a precise injection.

Your body is built to repair itself and our goal is to save your ACL, not replace it. We offer a non-surgical alternative for ACL tears that requires advanced injection skills using X-ray guidance, which may aide the healing of your ACL tear, while reducing pain and increasing function.

Multiple studies show that meniscus surgery doesn’t work.

If your MRI shows a meniscus tear, you might be asking: Do I need surgery?

But here’s the more important question: Is the torn meniscus causing my knee pain?

Dr. Pastoriza is a physiatrist with specialty training in interventional pain management and new to Interventional Orthopedics at the Centeno- Schultz clinic. Her interests are primarily in the biomechanics of the human body and in the applications of regenerative medicine for a multitude of injuries in an effort to help patients avoid a more invasive operative intervention. She is from Miami, FL and fluent in both English and Spanish.  She received her undergraduate degree from the University of Florida in Biological Engineering and a minor in Biomechanics.  She competed for the University of Florida Track and Field team as a Javelin thrower and suffered a career ending shoulder injury prompting a more personal interest in biomechanics. Her personal experiences led to an interest in research at the Motion Analysis Laboratory in Gainesville, FL wherein analyzing the throwing mechanics of the baseball and football players helped them to perfect their mechanics. Prior to entering medical school, she worked as a computer programmer at the VA hospital in Gainesville, performing gait analysis kinematics at the Neurorehabilitation Research Center which led to expanding the knowledge of the neuroplasticity that occurs after a stroke.

She attended Lake Erie College of Osteopathic Medicine in Bradenton, FL where she received her medical degree and became an expert in osteopathic manipulations as an adjunct to medical therapies truly taking into consideration all aspects of a patient’s life to help them heal. During this time she was exposed to the healing properties of regenerative medicine after suffering an ankle injury and undergoing a Regenexx procedure to help with instability which helped her avoid a major surgery.  Physical Medicine and Rehabilitation intertwines all aspects of osteopathy along with focusing on improving function and maintaining the highest quality of life given any diagnosis.  She completed her residency in Physical Medicine and Rehabilitation at MetroHealth Medical Center in Cleveland, OH.  Her interest in image-guided procedural interventions led her to complete an Anesthesiology Pain Medicine Fellowship at the University of Alabama in Birmingham. There she became proficient in chronic pain management.

Dr. Pastoriza is excited to embark on this next journey as part of the team at Centeno-Schultz Clinic learning from the regenerative medicine experts. She would like to treat patients with the highest quality of care combining a thorough physical examination and diagnostics to deliver precise image-guided procedures for all musculoskeletal areas of the body.

Outside of the clinic, Dr. Pastoriza spends most of her time with her young son and husband. She and her family enjoy going on bike rides together, along with going to parks and swimming. Dr. Pastoriza’s other hobbies include swimming, cycling, triathlons and crocheting.
