Knee pain is one of the most common problems affecting movement, sport, work, and daily life. It can happen suddenly after an injury, or gradually after repeated stress, overuse, weakness, stiffness, or changes in activity.
One of the most useful clues is where you feel the pain. Pain at the front of the knee may suggest a different problem from pain at the back, inside, or outside of the knee. However, location alone is not enough for a diagnosis. A proper assessment is needed to understand which structures are involved and why the knee is painful.
At Madrid Health, we see knee pain in locals, expats, and tourists. It may be linked to running, gym training, long walks around Madrid, stairs, hills, commuting, work postures, or previous injuries.
Why knee pain can be difficult to diagnose
The knee is a complex joint. It includes bones, cartilage, ligaments, tendons, muscles, bursae, nerves, and joint surfaces. Pain may come from one structure or from several working together.
A knee problem may involve:
- Muscle strain
- Tendon irritation or tendinopathy
- Ligament sprain
- Meniscus irritation or tear
- Cartilage changes
- Joint inflammation
- Bursitis
- Arthritis or osteoarthritis
- Referred pain from the hip, ankle, or lower back
- Poor load tolerance after a sudden increase in activity
This is why two people can both say “my knee hurts” but need very different treatment plans.
Front knee pain
Pain at the front of the knee is often felt around the kneecap, below the kneecap, or above the kneecap.
Possible causes include:
- Patellofemoral pain syndrome
- Patellar tendinopathy or “jumper’s knee”
- Quadriceps tendon irritation
- Kneecap tracking issues
- Chondromalacia patellae
- Hoffa’s fat pad irritation
- Bursitis
- Overload from stairs, squats, running, or jumping
Front knee pain often becomes worse with:
- Stairs
- Squats
- Lunges
- Running
- Jumping
- Sitting for long periods
- Getting up from a chair
- Walking downhill
This type of knee pain is common in runners, gym users, office workers, people returning to exercise, and visitors walking long distances each day.
Pain below the kneecap
Pain just below the kneecap may involve the patellar tendon, which connects the kneecap to the shin bone.
This area can become irritated after repeated jumping, running, hill training, squats, or rapid increases in training. It may feel painful when loading the knee, especially during explosive movement or deeper knee bending.
Possible causes include:
- Patellar tendinopathy
- Patellar tendon irritation
- Osgood-Schlatter-related pain in adolescents
- Fat pad irritation
- Bursitis
A good treatment plan usually focuses on load management, strengthening, movement control, and gradual return to sport or activity.
Pain above the kneecap
Pain above the kneecap may involve the quadriceps tendon or the muscles at the front of the thigh.
Possible causes include:
- Quadriceps tendinopathy
- Quadriceps strain
- Overload from squats, stairs, running, or jumping
- Reduced hip or ankle mobility increasing stress at the knee
- Weakness or poor load distribution
This pain can be common after gym training, hill walking, repeated stairs, or returning to exercise too quickly.
Inside knee pain
Pain on the inside of the knee is called medial knee pain. It may be felt along the inner joint line, slightly below the joint, or around the inner side of the kneecap.
Possible causes include:
- Medial meniscus irritation or tear
- Medial collateral ligament sprain
- Pes anserine tendinopathy or bursitis
- Medial joint irritation
- Osteoarthritis affecting the inner compartment
- Referred pain from the hip or lower back
Inside knee pain may be worse with:
- Twisting
- Pivoting
- Running
- Stairs
- Squatting
- Kneeling
- Getting in or out of a car
- Walking on uneven ground
If the knee locks, gives way, swells significantly, or pain began after a twisting injury, it is important to get assessed.
Outside knee pain
Pain on the outside of the knee is called lateral knee pain. It may be felt along the outer joint line, near the outer thigh, or around the outside of the kneecap.
Possible causes include:
- Iliotibial band syndrome
- Lateral meniscus irritation or tear
- Lateral collateral ligament sprain
- Lateral joint irritation
- Patellofemoral pain
- Tendon irritation around the outer knee
- Referred pain from the hip, ankle, or lower back
Outside knee pain is common in runners, cyclists, hikers, and people who suddenly increase walking or training volume.
It may be worse with:
- Running
- Walking downhill
- Cycling
- Repeated bending and straightening
- Stairs
- Side-to-side movements
- Uneven pavements or slopes
Treatment often needs to look beyond the knee itself, including hip strength, foot mechanics, running technique, and training load.
Back of knee pain
Pain at the back of the knee is called posterior knee pain. It may feel tight, sharp, swollen, or like pressure behind the knee.
Possible causes include:
- Hamstring tendon irritation
- Calf or gastrocnemius strain
- Soleus muscle overload
- Popliteus muscle irritation
- Baker’s cyst
- Posterior meniscus irritation
- Posterior capsule irritation
- Referred pain from the lower back or sciatic nerve
Back of knee pain may be worse with:
- Walking uphill or downhill
- Running
- Deep knee bending
- Fully straightening the knee
- Standing for long periods
- Sudden acceleration or deceleration
- Calf raises or hamstring loading
If you notice significant swelling behind the knee, calf swelling, warmth, redness, or sudden unexplained pain, seek medical advice.
Pain around the whole knee
Sometimes pain is not clearly located in one area. The whole knee may feel sore, swollen, stiff, unstable, or difficult to move.
Possible causes include:
- Knee swelling after injury
- Osteoarthritis
- Inflammatory arthritis
- Major ligament injury
- Meniscus injury
- Infection
- General overload
- Referred pain from another area
Whole-knee pain needs careful assessment, especially if there is swelling, heat, redness, fever, inability to bear weight, or major loss of movement.
Knee pain after walking around Madrid
Tourists often develop knee pain after a sudden increase in daily steps. Madrid is a very walkable city, but long sightseeing days can mean hours on hard pavements, stairs, hills, museums, parks, and metro stations.
This sudden change in load can irritate the knee, especially if you are not used to that level of walking.
Helpful first steps may include:
- Reducing walking distance temporarily
- Taking more frequent breaks
- Wearing supportive shoes
- Avoiding unnecessary stairs and hills
- Using ice if the knee is irritated or swollen
- Avoiding “pushing through” worsening pain
- Booking an assessment if symptoms are limiting your trip
The aim is to reduce irritation while keeping you moving safely.
Knee pain from running or sport
Knee pain in runners and athletes is often related to load, strength, mobility, recovery, or technique.
Common triggers include:
- Increasing distance too quickly
- Adding hills or speed work too soon
- Changing shoes
- Running on cambered or uneven surfaces
- Returning after time off
- Weakness in the hip, thigh, calf, or foot
- Reduced ankle or hip mobility
- Poor recovery between sessions
A physiotherapy assessment can help identify whether the knee is irritated because of the knee itself or because the hip, ankle, foot, or training plan is contributing.
How physiotherapy can help knee pain
Physiotherapy can help by identifying the likely source of pain and creating a plan to improve movement, strength, and load tolerance.
A physiotherapy plan may include:
- Knee assessment and diagnosis
- Strength testing
- Mobility assessment
- Walking, running, or squat analysis
- Pain and swelling management
- Progressive strengthening
- Balance and stability work
- Hip, ankle, and foot exercises
- Return-to-running or return-to-sport planning
- Advice on footwear, training load, and daily activity
The goal is not only to reduce pain, but to help the knee tolerate the demands of your normal life.
Can chiropractic care help knee pain?
Chiropractic care may help when knee pain is linked with movement restrictions, altered mechanics, or issues in related areas such as the hip, pelvis, ankle, or lower back.
At Madrid Health, the right approach depends on the cause of the knee pain. Some patients may benefit from physiotherapy, some from chiropractic care, and some from a combined approach. If symptoms suggest a more serious injury or medical condition, referral for imaging or medical assessment may be appropriate.
Do you need imaging for knee pain?
Not always. Many knee problems can be assessed clinically and treated without immediate imaging.
Imaging may be useful if:
- Symptoms follow a significant injury
- The knee is badly swollen
- There is locking, giving way, or suspected structural damage
- Pain is severe or persistent
- There is concern about fracture, meniscus injury, ligament injury, or arthritis
- Symptoms are not improving with appropriate care
A clinical assessment can help decide whether X-ray, MRI, ultrasound, or medical referral is needed.
What can you do at home?
For mild knee pain, simple steps may help:
- Reduce painful activities temporarily
- Avoid sudden spikes in walking, running, or gym training
- Use supportive footwear
- Apply ice if the knee is swollen or irritated
- Keep gentle movement if comfortable
- Avoid complete rest for too long
- Gradually rebuild activity
- Seek professional advice if symptoms persist or worsen
Do not ignore severe pain, instability, locking, major swelling, fever, redness, or inability to bear weight.
When should you seek professional help?
Book an assessment if:
- Knee pain lasts more than one or two weeks
- Pain keeps returning with activity
- You are limping or avoiding normal movement
- You have swelling or stiffness
- You feel weakness or instability
- You cannot return to sport or exercise
- Your knee pain is affecting work, travel, or sleep
- You are unsure what is causing the pain
Seek urgent medical advice if:
- You cannot bear weight
- The knee is very swollen
- The knee has changed shape
- The knee locks or gives way
- You have fever, redness, or heat around the knee
- You had a major fall or injury
- You cannot move the knee properly
FAQ
What does pain at the front of the knee mean?
Front knee pain may involve the kneecap, patellar tendon, quadriceps tendon, fat pad, or patellofemoral joint. It is often worse with stairs, squats, running, jumping, or sitting for long periods.
What causes pain on the inside of the knee?
Inside knee pain may involve the medial meniscus, medial collateral ligament, pes anserine tendons, medial joint line, or osteoarthritis. It can also be linked with twisting injuries or overuse.
What causes pain on the outside of the knee?
Outside knee pain may involve the iliotibial band, lateral meniscus, lateral collateral ligament, outer joint line, or hip and foot mechanics. It is common in runners and cyclists.
What causes pain at the back of the knee?
Back of knee pain may involve the hamstrings, calf, soleus, popliteus, Baker’s cyst, posterior meniscus, or referred pain from the lower back.
Can knee pain come from the hip or back?
Yes. Pain around the knee can sometimes be referred from the hip, pelvis, lower back, or nerves. This is one reason a full assessment is important.
Should I stop exercising if I have knee pain?
Not always. You may need to modify exercise rather than stop completely. The right decision depends on pain severity, swelling, instability, and how the knee responds during and after activity.
When is knee pain serious?
Knee pain may be more serious if you cannot bear weight, the knee is very swollen, locked, unstable, red, hot, deformed, or associated with fever or a major injury.
Can physiotherapy help knee pain?
Yes. Physiotherapy can help many types of knee pain by improving strength, movement, balance, load tolerance, and activity progression.
Summary
Knee pain location can provide useful clues. Front knee pain, inside knee pain, outside knee pain, and back of knee pain often involve different structures and movement patterns.
However, the location of pain is only part of the picture. The best treatment depends on how the pain started, what makes it worse, whether there is swelling or instability, and how the knee functions during daily life, sport, work, or travel.
If knee pain is affecting your movement, exercise, work, or visit to Madrid, a professional assessment can help identify the likely cause and guide the right treatment plan.
