Pes Anserine Bursitis Exercises: Relieve Inner Knee Pain

Pes anserine bursitis causes pain on the inside of the knee, just below the joint line. The pes anserine ("goose's foot") is where three tendons meet at the inner shin, and the bursa beneath them can become irritated and inflamed. These exercises help reduce irritation and strengthen the supporting muscles.

Understanding Pes Anserine Bursitis

What's happening:

• Bursa beneath pes anserine becomes inflamed
• Pes anserine = insertion point of three tendons
• Located 2-3 inches below inner knee joint

The pes anserine:

• "Goose's foot" shape from three tendons:
  • Sartorius (from hip)
  • Gracilis (from inner thigh)
  • Semitendinosus (hamstring)
• All three flex the knee and rotate the shin inward
• Bursa reduces friction between tendons and bone

Common causes:

• Overuse from repetitive knee flexion
• Tight hamstrings
• Obesity
• Knee osteoarthritis
• Improper training (especially running)
• Pes planus (flat feet)
• Sudden increase in activity
• Direct trauma

Who gets it:

• Runners and athletes
• Overweight individuals
• People with knee osteoarthritis
• Middle-aged women
• Swimmers (breaststroke)

Symptoms of Pes Anserine Bursitis

Classic presentation:

• Pain on inner knee, 2-3 inches below joint line
• Point tenderness over pes anserine area
• Pain climbing stairs
• Pain with resisted knee flexion
• Morning stiffness

Pain pattern:

• Worse with activity (running, stairs)
• May have night pain
• Swelling over the area
• Pain with knee bending under load

Differentiate from:

• MCL injury (higher, along joint line)
• Medial meniscus tear (joint line)
• Knee osteoarthritis (can coexist)

Phase 1: Reduce Inflammation

Initial Management

Rest: Reduce aggravating activities Ice: 15-20 minutes, 3-4 times daily Compression: Light wrap if swollen Elevation: When resting

Avoid Aggravating Activities:

• Running (temporarily)
• Deep squats
• Lunges
• Stairs (minimize)
• Breaststroke swimming
• Pivoting and cutting sports

Sleeping Position

If pain at night:

• Pillow between knees when side-lying
• Prevents knees from pressing together
• Reduces irritation

Phase 2: Stretching

Hamstring Stretch

Tight hamstrings directly pull on pes anserine.

Supine version:

1. Lie on back
2. Lift affected leg, keeping knee straight
3. Hold behind thigh or use strap
4. Feel stretch in back of thigh
5. Hold 30-60 seconds
6. Repeat 3 times

2. Keep knee straight
3. Lean forward from hips
4. Hold 30-60 seconds
5. Repeat 3 times

Gracilis Stretch (Inner Thigh)

Strength:

• Regular hamstring stretching
• Maintain quad and hip strength
• Address muscle imbalances

Footwear:

• Replace worn shoes
• Address flat feet with orthotics
• Proper shoes for activity

Weight management:

• Excess weight increases knee stress
• Even small weight loss helps

When to Seek Medical Care

See a doctor if:

• No improvement after 4-6 weeks
• Severe pain limiting daily activities
• Significant swelling
• Knee instability
• Suspected infection (redness, warmth, fever)

Treatment options:

• Physical therapy
• Corticosteroid injection
• NSAIDs
• PRP injection (in some cases)
• Surgery (rare)

Key Takeaways

1. Location is key: Pain below inner knee, not at joint line
2. Stretch the hamstrings: Tight hamstrings major contributor
3. Strengthen quadriceps: Supports knee function
4. Address flat feet: Orthotics may be essential
5. Ice and rest early: Reduces inflammation
6. Gradual return to activity: Don't rush back to running
7. Weight matters: Reduces stress on knee

With proper treatment, most cases of pes anserine bursitis resolve within 6-8 weeks. Maintenance stretching and strengthening prevent recurrence.
