Running is a great way to improve your cardiovascular health, build endurance, and stay active. But when knee pain starts interfering with your runs, it can quickly turn something you enjoy into a frustrating experience.
Maybe your knee starts aching a mile into your run. Perhaps you notice pain when going downstairs after a workout, or your knee feels stiff after sitting for an extended period. Whatever the symptoms, knee pain can make it difficult to know whether you should keep running, take time off, or seek professional help.
The good news is that many common running-related knee problems can improve with the right combination of activity modification, strength training, and a gradual return to running.
At Stride Physical Therapy, we believe the key is understanding why your knee hurts rather than simply trying to make the pain go away. Here is what you should know about managing knee pain and getting back to the activities you enjoy.
What Causes Knee Pain When Running?
Knee pain doesn’t always mean something is damaged inside your knee. Often, symptoms develop when the demands of your training exceed your body’s current capacity to handle them.
This can happen when you increase your mileage too quickly, add more hills or speed work, return to running after a break, or consistently run without enough recovery between workouts.
Other factors, including muscle strength, mobility, previous injuries, sleep, and overall training load, can also influence how your knee responds to running.
Common Types of Running-Related Knee Pain
The location of your pain can provide helpful clues about what might be contributing to your symptoms. However, pain location alone cannot confirm a diagnosis.
Pain around or behind the kneecap
Patellofemoral pain, commonly called runner’s knee, often causes aching around or behind the kneecap. Symptoms may become more noticeable when running downhill, climbing stairs, squatting, or sitting with your knees bent for long periods.
Treatment often involves gradually improving your tolerance to running while strengthening the quadriceps, hips, and other muscles that help you control lower-body movement.
Pain on the outside of the knee
Pain along the outer knee may be associated with iliotibial band-related pain, particularly in runners who increase their mileage or hill training too quickly.
Symptoms may become more noticeable after running a certain distance or when repeatedly running downhill. Treatment typically focuses on adjusting training demands and addressing relevant strength, movement, and load-tolerance factors.
Pain below the kneecap
Pain just below the kneecap can be associated with patellar tendinopathy, which involves the tendon connecting the kneecap to the shinbone.
This condition is often aggravated by repetitive loading, jumping, sprinting, and other activities that place substantial demands on the knee extensor mechanism. A progressive strengthening program can help the tendon tolerate these demands more effectively.
Pain along the inside of the knee
Inner knee pain can have several causes, including irritation of the meniscus, joint-related conditions, tendon problems, or other soft-tissue injuries.
If your symptoms began suddenly, particularly with a twisting injury, or you experience locking, significant swelling, or a feeling that your knee is giving way, an appropriate clinical evaluation is important.
5 Ways to Help Reduce Knee Pain From Running
The best approach depends on the underlying problem, but these strategies can help many runners manage symptoms and work toward returning to their normal training routine.
1. Adjust Your Running Volume Instead of Automatically Stopping All Activity
When knee pain develops, your first instinct might be to push through it or stop exercising completely.
Neither approach is necessarily the best solution.
Continuing to run at the same intensity despite worsening symptoms may aggravate the problem. On the other hand, avoiding all movement for an extended period can reduce your strength and tolerance for activity.
Instead, consider temporarily reducing your running distance, pace, hill work, or weekly frequency. You may be able to continue running at a lower level without significantly aggravating your symptoms.
Pay attention to how your knee feels during exercise and over the following 24 hours. If pain increases as you run, changes your stride, or remains noticeably worse afterward, reduce the demands further.
If running remains uncomfortable, lower-impact activities such as cycling or swimming may help you maintain cardiovascular fitness while you address the problem.
2. Build Strength in Your Legs and Hips
Running requires your muscles to absorb and produce force thousands of times during a single workout. If your current strength and load tolerance are insufficient for your training demands, symptoms may develop.
Strength training can help improve your ability to tolerate those demands.
Depending on your symptoms and current abilities, useful exercises may include:
- Squats or sit-to-stands
- Step-ups and step-downs
- Split squats
- Calf raises
- Hip abduction exercises
- Hamstring strengthening
You don’t necessarily need to perform every exercise on this list. The goal is to select movements that address your individual limitations and gradually increase resistance as your capacity improves.
Start with a manageable level of difficulty and progress over time. If an exercise consistently aggravates your knee, a physical therapist can help you modify the movement or choose an appropriate alternative.
3. Pay Attention to Your Training Progression
One of the most common contributors to running-related pain is increasing training demands faster than your body can adapt.
For example, you might feel comfortable running two miles several times per week. Suddenly increasing your distance to five miles, adding speed intervals, and running more hills creates a substantial change in your overall workload.
Even if your cardiovascular fitness allows you to complete those workouts, your muscles, tendons, and joints may need more time to adapt.
Try making gradual changes to your distance, intensity, and frequency rather than increasing everything at once. Build in adequate recovery between demanding sessions, especially when returning from an injury or an extended break.
There is no single mileage-increase rule that works for every runner. Your progression should reflect your symptoms, training history, recovery, and current physical capacity.
4. Evaluate Your Running Mechanics and Equipment
Your running technique, footwear, and training environment may influence how your body responds to exercise. However, there is no universally perfect running form or shoe that prevents every knee injury.
For some runners, modifying an overly long stride or making a small adjustment to cadence may reduce knee loading or improve comfort. For others, changing their technique may not be necessary.
The same applies to footwear. A comfortable, appropriately fitting shoe that suits your needs is generally a sensible starting point, but expensive shoes or a particular shoe design are not guaranteed to eliminate knee pain.
Rather than changing everything at once, identify whether a particular training condition, surface, pace, or footwear choice consistently affects your symptoms.
A physical therapist experienced in treating runners can assess your running mechanics and determine whether a technique adjustment is likely to be helpful.
5. Give Your Body Time to Recover and Adapt
Recovery is an important part of improving your running performance and managing pain.
Adequate sleep, appropriate nutrition, and sufficient time between demanding workouts all support your ability to adapt to training.
If your knee is swollen or irritated after a run, temporarily reducing aggravating activities may help. Ice can provide short-term pain relief for some people, although it does not address the underlying cause of the problem.
You do not necessarily need to stop all exercise while your knee improves. The objective is to find a level of activity you can tolerate while gradually rebuilding your capacity.
Avoid rushing back to your previous mileage simply because your symptoms have started to improve. Your knee may feel better before it has regained the strength and tolerance needed for your usual running routine.
When Should You See a Physical Therapist for Knee Pain?
Occasional soreness does not always indicate a serious injury. However, persistent or recurring knee pain deserves attention, especially if it prevents you from running comfortably.
A physical therapist can evaluate your symptoms, strength, mobility, balance, running mechanics, and training history to help identify the factors contributing to your pain.
Your evaluation may include:
- Assessing knee, hip, and ankle strength
- Evaluating joint mobility and lower-body movement
- Identifying activities or training demands that aggravate symptoms
- Analyzing your running mechanics when appropriate
- Developing an individualized strengthening and return-to-running plan
The goal is not simply to get you through your next run. It is to help you build the strength and capacity needed to return to running with greater confidence.
Seek prompt medical evaluation if you experience significant swelling after an injury, an inability to bear weight, a locked knee, marked instability, or a hot, red knee accompanied by fever.
