What may help

This is general information, not a plan for any one person.

What a plan may include

  • Exercise for the hip and thigh muscles is usually the center of a plan.
  • Stretching the front and back of the thigh, and strengthening the core muscles, can be part of it.
  • Taping or shoe inserts may be used alongside exercise.
  • Coordination training and a gradual return to activity can follow.

Everyday adjustments

  • Changing how you exercise.
  • Building activity up gradually.
  • Wearing proper sports shoes.

Rest on its own tends to ease it only for a while.

How it is described

People describe:

  • Pain on stairs or hills, during sports, with deep squatting, or after sitting a long time with the knee bent.
  • A dull, aching pain behind, below or beside the kneecap.
  • Grinding when the knee bends.
  • Pain that is worse with deep knee bends, stairs and running downhill.

What may contribute

Several things may play a part:

  • Increasing activity faster than the knee can adapt.
  • Weak or tight thigh muscles.
  • Focusing on a single sport.
  • A kneecap that does not move smoothly.
  • Overuse.

What an evaluation may look at

An evaluation may include:

  • Analyzing the movements that cause pain and ruling out other conditions.
  • Possibly looking at how you walk or run, and testing hip and thigh strength.
  • Imaging is usually not needed to diagnose it. A physical therapist may consult an orthopedic (bone and joint) physician, who may order imaging.

How Physical Therapy may fit

A Shanti physical therapist begins with an evaluation. If Physical Therapy looks like a good fit, the plan is built around what the evaluation shows. Depending on the findings, a plan may use some, all or none of these approaches:

Safety note

When to seek medical care

Seek urgent medical care after a serious injury if you cannot put weight on the leg, or if the leg or joint looks deformed. Contact a medical professional for severe or worsening symptoms, fever, or concerns after an operation.

When to get medical care first

Get emergency care right away if:

  • you cannot put weight on the knee after an injury;
  • your knee looks deformed;
  • your calf or foot has numbness, tingling or a bluish color;
  • your foot feels cool or looks blue after a knee injury. This can mean the knee has come out of joint, which is an emergency.

Contact a medical professional promptly if:

  • your knee buckles, clicks or locks;
  • your knee is still painful after 3 days of home treatment;
  • the pain is severe;
  • you have trouble bending or straightening the knee;
  • you have a fever;
  • your knee is red or warm;
  • your knee is heavily swollen;
  • your calf hurts or swells;
  • an activity keeps bringing on knee pain. Get it checked before it gets worse.

Also contact a medical professional about:

  • a knee that feels unstable;
  • swelling.

If you are unsure what is causing your symptoms, ask a medical professional. Information online is not a diagnosis.
