Knee Injuries and Conditions: Knee Pain

Knee pain is a common complaint that affects people of all ages. Knee pain can result from an injury, such as a ruptured ligament or torn cartilage, or from medical conditions like arthritis, gout, and infections. 

While many types of minor knee pain respond well to self-care measures, physical therapy, and knee braces, some cases may require surgical repair.

Knee

How do knee injuries and conditions usually occur?

Knee injuries can occur due to a sudden injury or repetitive stress. These injuries may include ligament tears, fractures, and dislocations. Here’s a breakdown of common causes:

Acute Conditions

  •  ACL Injury: Caused by sudden changes in direction, common in sports like soccer, basketball, and football.
  • Fractures: Often result from falls, auto accidents, or osteoporosis.
  • Torn Meniscus: Typically due to twisting the knee while bearing weight.
  • Knee Bursitis: Inflammation caused by repetitive motion or direct impact.
  • Patellar Tendinitis: Common in runners, jumpers, and athletes who engage in high-impact activities.

 

Chronic Conditions

  • Osteoarthritis: Wear-and-tear condition causing deterioration of knee cartilage.
  • Rheumatoid Arthritis: An autoimmune disease affecting knee joints.
  • Gout and Pseudogout: Caused by crystal buildup in the knee joint.
  • Septic Arthritis: Infection in the knee joint leading to severe pain and swelling.

 

Other Conditions

  • Loose Body: Fragments of bone or cartilage floating in the knee joint space.
  • Iliotibial Band Syndrome: Tightness of the iliotibial band causing pain.
  • Dislocated Kneecap: Patella slips out of place, often due to injury.

Understanding the Anatomy of the Knee

The knee is a complex joint made up of several components that work together to enable movement and provide stability.


Regions of the Knee

  • Femur (Thighbone)
  • Tibia (Shinbone)
  • Patella (Kneecap)

 

Parts of the Knee

  • Bones: Femur, tibia, and patella.
  • Cartilage: Articular cartilage and meniscus.
  • Ligaments: Collateral and cruciate ligaments.
  • Tendons: Quadriceps and patellar tendons.


Who Gets Knee Pain?

Knee pain can affect individuals of all ages and activity levels, from athletes to those with arthritis.

  • Athletes: Higher risk of ligament and tendon injuries.
  • Older Adults: More likely to experience arthritis-related knee pain.
  • Workers: Jobs requiring repetitive knee movement increase the risk of knee injuries.


Types of Knee Pain

  • Acute: Sudden injury causing immediate pain.
  • Chronic: Ongoing pain due to conditions like arthritis.


Symptoms of Knee Pain

  • Swelling and stiffness
  • Redness and warmth
  • Weakness or instability
  • Popping or crunching noises
  • Inability to fully straighten the knee


Causes of Knee Pain

  • Sports injuries
  • Accidents and falls
  • Repetitive motion or overuse
  • Medical conditions like arthritis
