Knee Pain

The knee joint

The knee joint is a hinge joint that connects the thigh bone (femur) to the shinbone (tibia). It is the largest joint in the human body and is essential for activities that involve weight-bearing and movement, such as walking, running, jumping, and bending.

The knee is a complex joint, with multiple structures within and outside the joint.  Knee pain is a common condition that affects athletes as well as non-athletes.  Knee pain can be from general wear and tear that happens with time, from injuries/trauma, or both.

Common symptoms

Knee pain can be caused by a variety of factors, ranging from acute injuries to chronic conditions. Here are some common causes of knee pain:

  1. Strains and Sprains:

    • Description: Overstretching or tearing of ligaments (sprains) or muscles and tendons (strains) around the knee.
    • Symptoms: Pain, swelling, and difficulty moving the knee.
  2. Tendonitis:

    • Description: Inflammation of the tendons around the knee, often due to overuse or repetitive stress.
    • Symptoms: Pain, swelling, and tenderness.
  3. Meniscus Tears:

    • Description: Tears in the meniscus, which are cartilage pads that act as shock absorbers in the knee joint.
    • Symptoms: Pain, swelling, stiffness, and a clicking or popping sensation.
  4. Ligament Injuries:

    • Description: Injuries to the ligaments that provide stability to the knee, such as the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and lateral collateral ligament (LCL).
    • Symptoms: Instability, swelling, and pain, often accompanied by a popping sound at the time of injury.
  5. Osteoarthritis:

    • Description: Degeneration of the knee joint’s cartilage over time, commonly associated with aging.
    • Symptoms: Gradual onset of pain, stiffness, swelling, and reduced range of motion.
  6. Rheumatoid Arthritis:

    • Description: An autoimmune condition causing inflammation in the joints, including the knee.
    • Symptoms: Joint pain, swelling, stiffness, and fatigue.
  7. Patellofemoral Pain Syndrome (Runner’s Knee):

    • Description: Irritation of the cartilage on the underside of the patella (kneecap).
    • Symptoms: Dull, aching pain around or behind the patella, especially during activities like running or going up and down stairs.
  8. Bursitis:

    • Description: Inflammation of the bursae (fluid-filled sacs) around the knee joint.
    • Symptoms: Swelling, warmth, and pain, particularly with movement.
  9. Iliotibial (IT) Band Syndrome:

    • Description: Inflammation of the IT band, a fibrous band running along the outside of the thigh and knee.
    • Symptoms: Pain on the outer side of the knee, especially during activities like running or cycling.
  10. Gout:

    • Description: A type of arthritis caused by the accumulation of urate crystals in the joints, including the knee.
    • Symptoms: Sudden and severe pain, swelling, redness, and warmth in the affected joint.
  11. Infections:

    • Description: Infections in the knee joint or surrounding tissues.
    • Symptoms: Pain, swelling, redness, and sometimes fever.

Common Knee conditions

We diagnose and treat all knee conditions.  Below are some common knee conditions we manage at OrthoCare Innovations Center.

purposefully designed

At OrthoCare Innovations Center, we obtain a detailed history and physical exam, and order further tests as indicated (x-rays, MRI, CT, U/S, aspiration, etc), to make sure we obtain an accurate diagnosis.

Once the diagnosis has been obtained, we explain the condition in terms that are easily understood, and go over the treatment options, from conservative (usually medications and physical therapy), holistic, alternative, novel options that are being investigated, regenerative therapies (platelet rich plasma and/or stem cells), to surgical options if indicated.  We tailor the treatment protocol in concert with the patients activity level and goals.

If you feel like you don’t have an understanding of your knee pain/symptoms, or are not confident in the treatment options, schedule a consultation with us for a thorough and personalized evaluation and treatment.
