The Real Reasons Your Knee Hurts When You Move, Expert Insights
Knee pain is one of those problems people hope will go away on its own, yet it rarely does. The problem starts small, a little stiffness, a pinch when you walk, or a tug when you climb stairs. But over time, that discomfort can turn into sharp, constant knee pain that makes even simple movements feel risky.
This fear grows even more when you begin feeling pain on inside of knee when bending and straightening, because you’re not just uncomfortable anymore, you’re worried something is actually wrong. That worry is valid. Knee pain has a cause, and ignoring it can delay recovery, limit mobility, and, over time, damage the joint further.
But here’s the good news: most knee conditions are treatable, often without surgery, especially when addressed early. At Jersey Joint, Spine & Regen, we help patients every day understand what their pain means and exactly how to get ahead of it.

Why the Inside of Your Knee Hurts When You Move
Inner knee pain (medial knee pain) is one of the most common complaints among adults. If your knee hurts when you bend, squat, straighten, or even get out of a car, chances are one of these core issues is at play:
1.Medial Meniscus Irritation or Tear
The medial meniscus acts like a cushion inside the knee. Overuse, twisting movements, or even normal aging can cause it to wear down or tear. Common signs include:
- Sharp pain during bending
- Discomfort in straightening the leg
- Clicking or catching sensation
This is one of the top causes of pain on inside of knee when bending and straightening, especially if symptoms appear after exercise, a sudden twist, or lifting something heavy.
When to get help: If pain has lasted more than 7–10 days, or if locking occurs, early evaluation prevents long-term cartilage damage. Want clarity fast? Schedule a personalized knee evaluation at Jersey Joint, Spine & Regen, no guesswork, just answers.
2. MCL (Medial Collateral Ligament) Strain
The MCL stabilizes the inside of your knee. Even a minor strain can make movement painful. Sports injury, direct pressure on the knee, and quick pivoting movements could be some of the typical triggers. Symptoms include:
- Inner knee tenderness
- Swelling
- Pain during walking or turning
The good news: most MCL strains heal well with regenerative therapies and structured treatment plans, especially when diagnosed early.
3. Pes Anserine Bursitis
This is inflammation of a small fluid-filled sac on the inner side of your knee. It’s common in people who:
- Overtrain
- Have tight hamstrings
- Are overweight
- Walk or run with poor alignment
How it feels:
- A dull ache on the inside of the knee
- Pain during bending
- Discomfort when climbing stairs
This condition responds very well to targeted regenerative treatments offered at our clinic.
4. Early-Stage Arthritis
Many patients assume arthritis only happens to seniors, but medial knee arthritis can begin in your 30s, especially after:
- Old injuries
- Repetitive strain
- Untreated knee inflammation
Arthritis doesn’t always start with stiffness; sometimes the earliest sign is knee pain during bending and straightening. Why early detection matters? Arthritis progresses silently. The earlier you treat it, the more mobility you can preserve.
5. Patellofemoral Tracking Issues
If your kneecap is not aligned properly, it forces extra stress inside the knee joint. You may notice:
- Pain during squatting
- Pain walking downhill
- Sensation of the knee pulling inward
At Jersey Joint, Spine & Regen, this is one of the most commonly misdiagnosed causes of knee pain we identify and treat successfully.

Why Pain Gets Worse Over Time (If Left Untreated)
Knee pain rarely disappears on its own. Here’s what often happens instead:
- The joint becomes inflamed
- You change how you walk, adding more stress to the knee
- Nearby muscles weaken
- Cartilage begins to wear down
- Even simple activities trigger pain
The longer someone waits, the more complex the condition becomes, which is why early assessment is the single best step you can take. If your knee pain has lasted more than a week, book a consultation at Jersey Joint, Spine & Regen before it worsens.
