How do you treat “runner's knee”?

Runner's knee is characterized by dull pain around the patella. It can be caused by a structural defect or walking and running habits that cause it. A conservative therapeutic program should incorporate hip abductor, external rotator, and quadriceps strength, closed-chain exercises like squats and balance training. More aggressive treatment may require gait analysis (biomechanics) and custom orthotics.

Sports Medicine physicians are trained in the complete healthcare of athletes.

Both Sports Medicine Doctors and Orthopedic surgeons are trained in the care of musculoskeletal problems.

Do Chiropractors do Sports Medicine treatments?

Ultrasound provides very detailed images that allow a Sports Medicine Doctor to see if a body part is normal, or swollen, thickened, torn, or stretched with extra blood flow in or around the area. For some common sports related injuries diagnostic ultrasound has replaced other forms of advanced imaging, such as MRI. It provides the added advantage of allowing the physician to see body parts in motion. Ultrasound can be used to diagnose injuries to bones, joints muscles, tendons, ligaments and even nerves.

Is acupuncture a Sports Medicine treatment?

Chinese medicine has always been closely linked with sports, martial arts, and healing. Sports acupuncture is used to speed healing, relieve pain, and increase muscle strength and stamina. In some studies acupuncture produced an increase in physical performance capacity and better regulation of heart rate and blood pressure compared to placebo acupuncture and control. Runners treated with acupuncture showed statistically significant improvement. Treating sports conditions with medications can be limited by significant medication side-effects, making acupuncture a preferable alternative.

The primary goal of sports biomechanics is to improve athletic performance by identifying and applying optimal technique, preventing injury and speeding recovery.

By studying how the human body naturally wants to move recommendations can be made that remove stress and pressure on the bones, joints, muscles and ligaments.

How is multi-ligament knee injury treated?

These types of injuries are most commonly seen in higher level skiing and football athletes. A multi-ligament knee injury will often require serial surgeries for repair and then reconstruction. You should seek out an Orthopedic Surgeon who specializes in Sports Medicine with a focus on acute and complex knee injuries if you have this type of injury.

Do Sports Medicine Doctors do arthroscopy?

Arthroscopy is a common surgical technique for sports injuries. It is a minimally invasive procedure that uses a camera, fiber optic light and a magnifying lens to allow the surgeon to get a detailed view of the injury and repair it. Common injuries that can be treated using arthroscopy alone include tendon, ligament, and cartilage tears, rotator cuff tears, and inflamed joints. The knees, elbows, shoulders, ankles, hips, and wrists are most often treated with this method.

What is the treatment for tennis elbow?

There are both non-surgical and surgical techniques to treat tennis elbow. Conservative treatment may include: reduced activity, corticosteroid injections, extracorporeal shock wave therapy, icing, anti-inflammatory medication, range of motion exercises and physical therapy. If conservative methods do not provide relief, or if the injury stems from torn ligaments and tendons, surgery may be indicated. Most tennis elbow surgery will be arthroscopic. However, if the injury is complex, and there is serious tissue damage, or the tendon tear is large, open surgery may be required.

Should I have surgery for an Achilles rupture?

Treatment for a ruptured Achilles tendon depends on the age of the patient, their activity level and the severity of the injury. While both surgical and non-surgical treatments have shown fairly equal effectiveness, young athletes tend to choose surgery, whereas older patients tend to opt for non-surgical treatment. Non-surgical repair avoids the risks of surgery, but increases the chances of re-rupture.

What does medical clearance for my sports injury surgery consist of?

What is a pre op examination for sports injury surgery?

A preoperative physical examination is essentially the same thing as getting medical clearance.

Why do I need medical clearance for my sports injury surgery?

The purpose of medical clearance is to assess your personal risk related to undergoing a surgical procedure. If you have comorbidities your surgeon may want another doctor familiar with your medical history to offer perspective on whether the procedure is safe for you and ways to reduce risk.

Why do I need blood and urine tests before my sports injury surgery?

Your surgeon may require routine laboratory tests before your procedure to identify potential problems that might complicate surgery if not detected and treated in advance. A blood test will show if you have a blood-clotting problem and may be at risk of too much bleeding during surgery.  Urinalysis may be used to detect urinary tract infections, renal diseases and poorly controlled diabetes.

Who do I see to get medical clearance for my sports injury surgery?

Your Primary Care Physician is the Doctor who manages your medical care. He/she will provide the appropriate information.

Why is my surgeon recommending a surgery center instead of a hospital?

How does regenerative medicine help a sports injury?

Research has found that it is possible to use platelet-rich plasma (PRP) and adult stem cells to heal and even regenerate lost, damaged, or aging tissue. Regenerative therapy is the process of taking the body’s own healing stem cells and injecting them into an area of the body that has been injured. Stem cell injections, platelet-rich plasma (PRP), and prolotherapy are examples of regenerative medicine treatments available to treat sports injuries. However, prolotherapy treatments are not considered regenerative therapy unless they include platelet-rich plasma (PRP) and/or stem cells.

What is stem cell therapy?

Stem cells are the cells that develop into blood, brain, bones, and all of the body’s organs. They have the potential to repair, restore, replace, and regenerate cells. Stem cell therapy involves introducing stem cells into patients to replace damaged tissues. The most common sources of stems cells are: bone marrow, adipose tissue (fat) umbilical cord blood, amniotic fluid and allografts (donated tissue)

What is better for my knees, stem cells from fat or from bone marrow?

Adipose (fat) tissue provides the largest volume of adult stem cells and more importantly it provides a large volume of additional growth factors. Research studies have shown that every significant measurement comparing bone marrow to adipose tissue for stem cell harvesting demonstrated that adipose derived stem cells provided better cell content and superior ability to differentiate into cartilage than bone marrow.

What is MACI cartilage regeneration?

MACI stands for "matrix-induced autologous chondrocyte". Chondrocytes are the only cells found in healthy cartilage. MACI is a 2 part procedure in which cartilage is removed from the patient and sent to a lab to grow. Then, when it is ready a surgeon cuts it to fit the defect and glues it to the patient. Both procedures require some recovery, the second one being more extensive.

How is Kinesio tape used for sports injuries?

It is thought that Kinesio tape can provide support, lessen pain, reduce swelling, improve circulation, re-educate muscles, support weak zones and improve performance.
