Femoroacetabular Impingement (FAI) occurs when the femoral head (ball) and the acetabulum (socket) do not fit together perfectly. As a result, abnormal contact develops during hip movement, particularly during flexion, twisting, squatting, and athletic activities.

Over time, this repeated contact may lead to:

• Hip pain
• Labral tears
• Cartilage damage
• Reduced range of motion
• Early hip osteoarthritis

FAI commonly affects:

• Athletes
• Active adults
• Individuals involved in repetitive hip flexion activities

Many people may have structural changes associated with FAI without symptoms. However, when symptoms develop, early treatment can help prevent progression and improve function.

At Magnum Physiotherapy, our evidence-based rehabilitation programs focus on improving hip mechanics, enhancing mobility, strengthening supporting muscles, and reducing stress on the hip joint.

Anatomy Involved

Hip Joint

The hip is a ball-and-socket joint composed of:

Femoral Head

The ball-shaped top of the thigh bone.

Acetabulum

The socket portion of the pelvis.

Acetabular Labrum

A ring of cartilage surrounding the hip socket.

Functions include:

• Improving stability
• Absorbing shock
• Maintaining joint lubrication

Labral tears commonly occur in association with FAI.

Articular Cartilage

Smooth tissue covering the joint surfaces.

Repeated impingement can lead to cartilage damage.

Types of Hip Impingement

Cam Impingement

Occurs when the femoral head is not perfectly round.

Results In

• Abnormal contact during hip movement
• Increased stress on cartilage and the labrum

Most common in young athletes.

Pincer Impingement

Occurs when the acetabulum covers too much of the femoral head.

Results In

• Compression of the labrum
• Joint irritation

More common in middle-aged adults.

Mixed Impingement

The most common type.

Involves features of both:

• Cam impingement
• Pincer impingement

Common Symptoms

• Groin pain
• Deep hip pain
• Hip stiffness
• Reduced range of motion
• Pain during squatting
• Pain during prolonged sitting
• Clicking or catching sensations
• Pain during pivoting movements
• Difficulty running or participating in sports
• Hip discomfort after activity

Symptoms often worsen with activities involving hip flexion.

Causes & Risk Factors

Structural Hip Abnormalities

Abnormal bone development can contribute to FAI.

Repetitive Athletic Activities

Common in:

• Hockey
• Soccer
• Football
• Dance
• Gymnastics
• Running

Developmental Factors

FAI often develops during growth and adolescence.

Risk Factors

• Athletic participation
• High-impact sports
• Repetitive hip loading
• Family history
• Previous hip injuries

Conditions Associated with Hip Impingement

• Hip Labral Tears
• Hip Osteoarthritis
• Hip Instability
• Groin Pain Syndromes
• Athletic Hip Injuries
• Chondral (Cartilage) Injuries

Diagnosis

Accurate diagnosis requires a detailed assessment.

Clinical Examination

At Magnum Physiotherapy, assessment includes:

• Pain evaluation
• Hip mobility testing
• Strength assessment
• Gait analysis
• Functional movement evaluation

Special Tests

FADIR Test

(Flexion, Adduction, Internal Rotation)

Commonly reproduces symptoms associated with FAI.

FABER Test

Assesses hip and pelvic mobility.

Imaging Studies

X-rays

Often used to identify:

• Cam deformities
• Pincer deformities
• Joint changes

MRI

May evaluate:

• Labral tears
• Cartilage injuries
• Associated soft tissue damage

MRI Arthrogram

Provides detailed visualization of the labrum.

Treatment at Magnum Physiotherapy

Many patients achieve excellent outcomes with conservative physiotherapy treatment.

Pain Management

Activity Modification

Reducing activities that provoke symptoms helps decrease joint irritation.

Education

Patients learn strategies to reduce stress on the hip joint while maintaining activity.

Manual Therapy

May include:

• Joint Mobilization
• Soft Tissue Mobilization
• Myofascial Release

These techniques help improve mobility and reduce discomfort.

Mobility Exercises

Focus on:

• Hip flexibility
• Joint mobility
• Movement efficiency

Programs are individualized to avoid aggravating impingement symptoms.

Strengthening Programs

A cornerstone of rehabilitation.

Gluteal Strengthening

Improves hip stability and control.

Core Strengthening

Enhances pelvic alignment and movement efficiency.

Hip Stabilizer Training

Reduces stress on the joint during movement.

Movement Retraining

Focuses on:

• Squatting mechanics
• Running mechanics
• Athletic movement patterns
• Functional activities

Improving movement quality can significantly reduce symptoms.

Advanced Physiotherapy Treatments

Depending on individual needs:

• Class IV Laser Therapy
• Therapeutic Ultrasound
• TENS Therapy
• Interferential Therapy (IFT)
• Functional Movement Training

Medical Management

If symptoms remain significant despite conservative treatment:

Corticosteroid Injections

May provide temporary symptom relief and assist with diagnosis.

Arthroscopic Hip Surgery

May be recommended when:

• Symptoms persist
• Labral tears are present
• Functional limitations remain significant

Surgical procedures may include:

• Cam resection
• Pincer correction
• Labral repair
• Cartilage treatment

Post-Surgical Rehabilitation

Physiotherapy after surgery focuses on:

• Pain management
• Mobility restoration
• Strengthening
• Gait retraining
• Return-to-sport progression

Benefits of Physiotherapy for Hip Impingement

• Reduces pain
• Improves hip mobility
• Enhances joint stability
• Restores strength
• Improves movement mechanics
• Supports athletic performance
• Reduces stress on the hip joint
• Helps prevent further joint damage
• Supports return to activity
• Improves quality of life

Recovery & Prognosis

Recovery depends on:

• Severity of impingement
• Presence of labral or cartilage damage
• Activity level
• Participation in rehabilitation

Typical Recovery Timeline

Conservative Treatment

• 6–12 weeks or longer

Post-Surgical Recovery

• Approximately 3–6 months

Return to Competitive Sports

• Often 4–9 months depending on the sport and procedure performed

Many patients achieve significant improvements with appropriate treatment.

Prevention Tips

• Maintain hip strength and flexibility
• Use proper athletic techniques
• Improve core stability
• Avoid excessive repetitive hip loading
• Address hip pain early
• Follow structured training programs

When Should You Seek Medical Attention?

Consult a healthcare professional if you experience:

• Persistent groin pain
• Hip stiffness
• Hip clicking or catching
• Reduced range of motion
• Difficulty participating in sports or daily activities

Early assessment can help prevent progression and improve treatment outcomes.
