Dislocated Knee Cap
A dislocated kneecap, also called patella dislocation, occurs when the kneecap moves out of its normal position in the groove of the thigh bone. This injury often causes sudden knee pain, swelling, and difficulty moving the leg. Patella dislocations commonly occur during sports or sudden twisting movements. Physiotherapy treatment is essential for restoring knee stability, strengthening surrounding muscles, and reducing the risk of the kneecap dislocating again.
What is a Dislocated Kneecap?
The kneecap (patella) is a small triangular bone located at the front of the knee joint. It sits in a groove at the end of the thigh bone (femur) and moves up and down when the knee bends or straightens.
A dislocated kneecap occurs when the patella slips out of this groove, usually moving toward the outer side of the knee. When this happens, the knee joint becomes painful and unstable, making it difficult to walk or move the leg.
In many cases, the kneecap may remain displaced until it is manually relocated by a healthcare professional.
Causes
A dislocated kneecap usually occurs due to sudden movements or trauma to the knee.
Common causes include:
- Direct impact to the knee, such as falling onto the knee
- Sudden twisting or pivoting movements
- Rapid changes in direction during sports
- Jumping or landing awkwardly
- Weak quadriceps muscles
- Shallow kneecap groove (patellar instability)
- Previous knee injuries
Athletes involved in sports that require quick directional changes, such as football, basketball, or gymnastics, are more prone to this injury.
Symptoms
Symptoms of a dislocated kneecap usually appear suddenly.
Common symptoms include:
- Sudden sharp pain at the front of the knee
- The kneecap visibly shifted to the side
- Swelling around the knee
- Weakness in the knee
- Knee stiffness
- Reduced range of motion
- Difficulty walking or standing
- Feeling that the knee has “given way”
Swelling often develops within the first few hours after the injury.
What Should I Do?
If you suspect a dislocated kneecap, immediate medical attention is required.
You should:
- Seek care at the nearest emergency department
- Avoid putting weight on the injured leg
- Apply ice to the knee to reduce swelling
- Keep the leg elevated if possible
Use ice wrapped in a cloth and apply it for 15–20 minutes at a time to help reduce inflammation.
Physiotherapy Treatment
Physiotherapy plays a crucial role in recovery after a patella dislocation.
At ACE Physio Sports, physiotherapists design personalised rehabilitation programs to restore knee function and prevent recurrence.
Treatment may include:
Strengthening Exercises
Exercises focus on strengthening the quadriceps and hip muscles to improve kneecap stability.
Range of Motion Exercises
Gentle exercises help restore normal knee movement and reduce stiffness.
Taping Techniques
Special taping methods help improve kneecap alignment and tracking during movement.
Electrotherapy
Electrotherapy may help reduce pain and swelling while promoting tissue healing.
Hydrotherapy
Water-based exercises allow safe movement while reducing stress on the knee joint.
These treatments help patients gradually regain strength, mobility, and confidence in their knee.
What Shouldn’t I Do?
If you have a dislocated kneecap, avoid:
- Attempting to push the kneecap back into place
- Continuing sports or physical activity
- Ignoring knee pain or swelling
- Returning to activity too quickly
- Skipping physiotherapy rehabilitation
Improper handling of the injury can cause damage to ligaments, cartilage, or nerves.
Long-Term Effects or Recovery
Most people recover well after a dislocated kneecap with appropriate treatment and physiotherapy.
However, possible long-term complications may include:
- Recurrent kneecap dislocations
- Persistent knee instability
- Cartilage damage under the kneecap
- Increased risk of knee osteoarthritis
Physiotherapy rehabilitation helps strengthen the knee and reduce the likelihood of future dislocations.

Frequently Asked Questions
Why does my knee hurt when I go up or down stairs?
Stair pain is a hallmark of many knee conditions, including Dislocated Knee Cap. Stairs significantly increase the load through the knee joint and surrounding structures. Physiotherapy identifies where the weakness or irritation lies and targets it with specific exercises.
My knee swells after activity — is that serious?
Post-activity swelling in Dislocated Knee Cap indicates the knee is being irritated beyond its current tolerance. Physiotherapy can reduce inflammation, help modify your activity load, and progressively build the knee's capacity to handle more demand.
Can I still exercise with Dislocated Knee Cap?
Yes — low-impact exercise like swimming, cycling, and targeted strength training is usually fine and beneficial. Your physiotherapist will identify which activities are appropriate and create a programme that builds knee strength without aggravating your condition.
