Knee Pain Statistics
Understanding Your Knee
The knee is a complex joint where several structures can cause pain:
Bones
Femur, tibia, patella (kneecap)
Cartilage
Smooth tissue covering bones, meniscus
Ligaments
ACL, PCL, MCL, LCL - connect bones
Muscles & Tendons
Quadriceps, hamstrings, surrounding muscles
Most Common Causes of Knee Pain
Here are the leading causes of knee pain, their symptoms, and typical treatments:
Osteoarthritis
Most commonWear and tear of cartilage in the knee joint
Common Symptoms:
- Stiffness in the morning
- Pain after activity
- Grinding sensation
- Reduced range of motion
Treatment Approach:
Exercise, weight management, vibration therapy
Meniscus Tear
Very commonTear in the C-shaped cartilage that cushions the knee
Common Symptoms:
- Sharp pain when twisting
- Knee locking
- Swelling
- Difficulty straightening leg
Treatment Approach:
Rest, physical therapy, sometimes surgery
Ligament Injuries (ACL/MCL/PCL)
Common in athletesDamage to the bands of tissue connecting bones
Common Symptoms:
- Sudden sharp pain
- Knee instability
- Swelling
- Unable to bear weight
Treatment Approach:
Rehabilitation, possible surgery
Patellofemoral Pain Syndrome
CommonPain around or behind the kneecap (runner's knee)
Common Symptoms:
- Pain during activity
- Aching after sitting
- Grinding sounds
- Knee weakness
Treatment Approach:
Rest, strengthening exercises, activity modification
Bursitis
ModerateInflammation of fluid-filled sacs that cushion the knee
Common Symptoms:
- Swelling
- Warmth
- Tenderness
- Pain when kneeling
Treatment Approach:
Ice, rest, anti-inflammatory medication
Tendinitis
Common in active peopleInflammation of tendons around the knee
Common Symptoms:
- Pain during movement
- Stiffness
- Swelling
- Tenderness
Treatment Approach:
Rest, ice, gradual return to activity
Risk Factors for Knee Pain
Understanding your risk factors can help prevent knee problems:
Age
Risk increases with age, especially after 40
Contributing Factors:
- Natural wear and tear
- Decreased muscle mass
- Reduced flexibility
- Slower healing
Weight
Each extra pound adds 4 pounds of pressure on knees
Contributing Factors:
- Increased joint pressure
- Extra load on cartilage
- Higher inflammation
- Reduced mobility
Activity Level
Both too much and too little activity can cause problems
Contributing Factors:
- Sports participation
- Running on hard surfaces
- Sudden activity increases
- Poor technique
Previous Injury
Past injuries increase risk of future problems
Contributing Factors:
- Old fractures
- Previous surgeries
- Ligament damage
- Muscle imbalances
Genetics
Some people are genetically predisposed to knee problems
Contributing Factors:
- Family history
- Joint structure
- Connective tissue disorders
- Autoimmune conditions
When to Seek Medical Help
Different symptoms require different levels of urgency:
🚨 Immediate Medical Attention
- •Knee gives out or buckles
- •Cannot bear weight
- •Visible deformity
- •Fever with knee pain
- •Severe swelling
🚨 See Doctor Soon
- •Pain persists over a week
- •Knee locks or catches
- •Significant swelling
- •Numbness or tingling
- •Signs of infection
🚨 Monitor and Self-Care
- •Mild aching after activity
- •Minor morning stiffness
- •Occasional crackling sounds
- •Fatigue-related discomfort
How Knee Pain is Diagnosed
Healthcare providers use several methods to determine the cause of knee pain:
- When did the pain start?
- What activities make it worse?
- Any previous injuries?
- Family history of joint problems?
- Visual inspection for swelling or deformity
- Range of motion testing
- Stability tests
- Palpation for tender areas
- X-rays: Show bone structure and arthritis
- MRI: Detailed view of soft tissues
- CT scan: Detailed bone imaging
- Ultrasound: Real-time imaging of movement
Early Treatment Matters
Identifying and treating knee pain early can prevent long-term damage and improve outcomes.
