Knee and Leg Q&A

Why does my knee hurt?

Your knee is a complex joint that’s susceptible to injuries because it has to support much of your body’s weight while moving both back and forth and, sometimes, side to side. Landing wrong after a jump, twisting your knee, and overstressing your knee during sports or other repetitive activities can damage essential knee structures, including:

- Bone (fibula, tibia, femur, and patella)

- Cartilage (meniscus and articular)

- Ligaments (anterior and posterior cruciate; medial and lateral collaterals)

- Tendons (patellar and quadricep)

- Muscles (hamstrings and quadriceps)

- Nerves

- Synovial fluid (a liquid that nourishes the joint)

- Bursa (compartments that reduce friction in the joint)

When your knee is swollen, painful, or stiff you can have difficulty carrying out daily functions, such as standing, sleeping, walking, or running.

What are the risk factors for knee or leg pain?

Engaging in high-impact sports or activities that require jumping, running, or sudden stopping increases your risk of a knee or leg injury. Aging, poor health or repetitive motions such as squatting or kneeling can degrade the knee joint, leading to osteoarthritis or other injuries.

You could also have an underlying medical condition, such as the autoimmune disease lupus or a form of arthritis called gout, that can cause your knee to hurt.

What are the most common injuries that cause knee or leg pain?

Athletes, weekend warriors, and older women and men have a greater risk of knee injuries. Some of the most common sources of knee pain include:

- Injured bones

- Ligament laxity and damage

- Anterior cruciate ligament (ACL) sprains

- Tendon injuries

- Torn meniscus

- Osteoarthritis

A painful knee or leg can throw your entire body out of alignment. Treating your knee pain restores mobility and helps your body to function better.

What options do I have for treating my knee pain?

Dr. Silva customizes your treatment based on precise diagnosis of the source of your knee pain. In addition to supportive therapies, such as bracing and physical therapy, he can recommend injectable regenerative treatments that help you avoid surgery and stimulate healing, such as:

- Prolotherapy

- Platelet-rich plasma therapy (PRP)

- Cellular therapy

Dr. Silva’s approach is to heal your underlying injury rather than simply mask your pain. As a holistic practitioner, he believes dysfunction in one part of the body can negatively affect your other joints.

Conversely, healing an injury not only restores health to that specific area but can also restore balance and health to your entire body.
