A Patella Dislocation occurs when the kneecap is forced out of its normal alignment within the femoral groove (trochlear groove). Most dislocations occur laterally, meaning the patella shifts toward the outer side of the knee.

The injury may occur due to:

• Sudden twisting movements
• Pivoting during sports
• Direct trauma to the knee
• Falls
• Structural alignment issues

In many cases, the patella spontaneously returns to its normal position, while other cases require medical reduction.

A dislocation may also injure surrounding structures, including:

• Medial Patellofemoral Ligament (MPFL)
• Articular cartilage
• Bone surfaces
• Joint capsule

Proper rehabilitation is essential to restore normal knee mechanics and reduce the risk of recurrent dislocations.

At Magnum Physiotherapy, our evidence-based treatment programs focus on pain relief, strength development, movement correction, and long-term knee stability.

Anatomy Involved

Patella (Kneecap)

A small sesamoid bone located within the quadriceps tendon.

Functions

• Improves knee extension efficiency
• Protects the knee joint
• Assists force transmission through the quadriceps

Trochlear Groove

A groove at the lower end of the femur where the patella glides during knee movement.

Medial Patellofemoral Ligament (MPFL)

The primary soft tissue restraint that helps prevent the patella from moving outward.

Frequently injured during a dislocation.

Quadriceps Muscles

Especially the:

Vastus Medialis Obliquus (VMO)

Helps maintain proper patellar alignment.

Types of Patella Dislocation

First-Time Dislocation

The initial episode of patellar displacement.

Recurrent Patella Dislocation

Repeated episodes due to ongoing instability.

Traumatic Dislocation

Caused by a specific injury or impact.

Habitual Dislocation

Occurs repeatedly during normal knee movement.

Common Symptoms

• Sudden knee pain
• Visible displacement of the kneecap
• Knee swelling
• Feeling of instability
• Difficulty walking
• Inability to bend or straighten the knee comfortably
• Tenderness around the kneecap
• Sensation of the knee "giving way"
• Fear of movement following injury

After spontaneous reduction, symptoms may include ongoing pain and instability.

Causes & Risk Factors

Sports Injuries

Common in activities involving:

• Pivoting
• Jumping
• Sudden direction changes

Examples include:

• Soccer
• Basketball
• Volleyball
• Football

Direct Trauma

A blow to the knee may force the patella out of alignment.

Anatomical Factors

Risk may increase with:

• Shallow trochlear groove
• Patella alta (high-riding patella)
• Ligament laxity
• Increased Q-angle
• Femoral or tibial alignment abnormalities

Muscle Imbalances

Weakness of the quadriceps and hip stabilizers can contribute to instability.

Conditions Associated with Patella Dislocation

• Medial Patellofemoral Ligament (MPFL) Injury
• Patellofemoral Pain Syndrome
• Cartilage Injuries
• Osteochondral Fractures
• Recurrent Knee Instability

Diagnosis

A thorough evaluation helps determine injury severity and identify contributing factors.

Clinical Examination

At Magnum Physiotherapy, assessment includes:

• Knee stability testing
• Mobility evaluation
• Strength assessment
• Functional movement analysis
• Gait assessment

Imaging Studies

X-rays

Used to:

• Confirm alignment
• Identify fractures
• Assess anatomical factors

MRI

May evaluate:

• MPFL injuries
• Cartilage damage
• Bone bruising
• Associated soft tissue injuries

CT Scan

Sometimes used to evaluate bone alignment and instability risk.

Treatment at Magnum Physiotherapy

Many first-time dislocations can be successfully managed with physiotherapy.

Phase 1: Pain & Swelling Management

Goals

• Reduce pain
• Control swelling
• Protect healing structures

Interventions

• Activity modification
• Compression
• Ice therapy
• Gentle mobility exercises

Phase 2: Restore Range of Motion

Focuses on:

• Knee flexion
• Knee extension
• Patellar mobility

Movement is progressed gradually and safely.

Phase 3: Strengthening

A critical component of recovery.

Quadriceps Strengthening

Particularly the Vastus Medialis Obliquus (VMO).

Gluteal Strengthening

Improves lower limb alignment.

Core Strengthening

Enhances overall movement control.

Functional Lower Limb Training

Supports knee stability during activity.

Phase 4: Balance & Neuromuscular Training

Focuses on:

• Proprioception
• Dynamic stability
• Coordination
• Movement control

Phase 5: Return-to-Sport Rehabilitation

Includes:

• Agility training
• Plyometric exercises
• Sport-specific drills
• Gradual return-to-play progressio

Advanced Physiotherapy Treatments

Depending on individual needs:

• Manual Therapy
• Therapeutic Exercise
• Neuromuscular Re-Education
• Kinesiology Taping
• Functional Movement Training
• Balance Rehabilitation

Medical Management

Bracing

May be used during early recovery or return to sports.

Surgical Intervention

May be recommended when:

• Recurrent dislocations occur
• Significant cartilage injury exists
• Anatomical abnormalities contribute to instability

Common procedures include:

• MPFL reconstruction
• Trochleoplasty
• Tibial tubercle osteotomy

Post-surgical rehabilitation is essential for successful recovery.

Benefits of Physiotherapy for Patella Dislocation

• Reduces pain
• Restores mobility
• Improves quadriceps strength
• Enhances knee stability
• Improves balance and coordination
• Reduces recurrence risk
• Supports return to sports
• Improves confidence in movement
• Enhances functional performance
• Improves quality of life

Recovery & Prognosis

Recovery depends on:

• Severity of injury
• Presence of ligament or cartilage damage
• Anatomical risk factors
• Compliance with rehabilitation

Typical Recovery Timeline

First-Time Dislocation

• 6–12 weeks

Recurrent Instability Cases

• Several months

Post-Surgical Recovery

• Approximately 4–6 months or longer

Most patients can return to normal activities with appropriate rehabilitation.

Prevention Tips

• Strengthen quadriceps and hip muscles
• Improve balance and neuromuscular control
• Use proper sports techniques
• Address alignment issues early
• Follow injury prevention programs

When Should You Seek Medical Attention?

Consult a healthcare professional immediately if you experience:

• A visibly displaced kneecap
• Severe knee pain after injury
• Inability to bear weight
• Significant swelling
• Recurrent episodes of instability
• Knee locking or giving way

Prompt treatment can reduce complications and improve long-term outcomes.
