Inner knee pain during runs
Also Known As: Medial knee pain, runner’s knee (medial), pes anserine pain
What It Feels Like
A sharp or aching pain along the inner side of the knee
Pain often worsens with running, especially on hills or uneven terrain
May feel worse when changing direction, descending, or after prolonged activity
Some runners report tenderness to the touch just below the knee joint line
Why It Matters
Ignoring inner knee pain can lead to compensations, worsened mechanics, and longer recovery times. Early intervention is key to staying on track with your goals—whether you're training for a race in Eugene or enjoying long trail miles.
Common Causes of Inner Knee Pain While Running
🔹 Pes Anserine Tendinopathy or Bursitis
Inflammation or irritation where three tendons attach on the inner knee, common in runners with weak glutes or poor hip control.
🔹 Medial Collateral Ligament (MCL) Stress
While not always injured, the MCL can become overstressed from repetitive valgus movement (knee caving inward).
🔹 Foot and Ankle Mechanics
Overpronation or poor shock absorption shifts load medially, increasing strain on the knee.
🔹 Hip Weakness and Core Instability
Lack of control at the pelvis and hip often causes the knee to drift inward with every stride, stressing the inside of the joint.
🔹 Training Volume or Surface Changes
Increases in mileage, speed work, or trail running on cambered or uneven terrain (common around Eugene) can overload the medial knee.
Did You Know?
If inner knee pain shows up on Eugene trails or cambered roads, back off slanted surfaces and steep descents for a bit, rotate in flatter routes, and do not stack hard hill days too close together.

Inner knee pain is not always a “knee problem.” Sometimes the real driver is poor hip control, foot mechanics, or too much load too soon.
