Meniscus Injury | PhysioGain

Meniscus Injury

Twisted your knee and now it hurts, swells, or clicks? Learn what a meniscus injury is, how it's diagnosed, and how physiotherapy can help you recover safely.

The menisci are two C-shaped pieces of cartilage that help cushion and stabilize the knee. Many people recover successfully with rehabilitation and do not require surgery.

QUICK OVERVIEW

Meniscus Injury at a Glance

InformationDetails
What is it?A meniscus injury is damage to one of the two fibrocartilage discs that help absorb shock and stabilize the knee.
Common Age GroupTraumatic tears are common in younger athletes, while degenerative tears are more common after 40 years.
Typical Recovery TimeMild tears may improve within 6–12 weeks. Larger tears or post-surgical rehabilitation may require 3–6 months.
Common CausesTwisting injuries, sports, squatting, sudden direction changes, and age-related degeneration.
Pain LocationUsually along the inner (medial) or outer (lateral) joint line of the knee.
Treatment SuccessMany meniscus injuries recover successfully with physiotherapy and exercise. Surgery is reserved for selected cases.

COMMON SIGNS & SYMPTOMS

Is This What You're Feeling?

ðŸĶĩ

Knee Pain

Pain along the inner or outer side of the knee, particularly during twisting or squatting.

💧

Swelling

Swelling may develop within hours or over the following day after injury.

🔊

Clicking or Catching

The knee may click or catch during movement.

🔒

Locking

The knee becomes stuck and cannot fully straighten. This requires prompt assessment.

📏

Stiffness

Difficulty bending or straightening the knee fully.

ðŸĶĩ

Pain While Squatting

Deep knee bending often aggravates symptoms.

🔄

Pain During Twisting

Turning, pivoting, or changing direction may increase discomfort.

⚠ïļ

Feeling of Instability

Some individuals feel the knee is less stable.

COMMON CAUSES

Why Does It Happen?

🔄

Twisting Injury

The most common cause in younger people, often occurring when the foot remains planted while the body twists.

🏀

Sports Injuries

Football, basketball, skiing, rugby, cricket, badminton, and other pivoting sports commonly involve meniscal injuries.

ðŸĶī

Degenerative Changes

With age, the meniscus becomes less resilient and may tear during relatively minor movements.

ðŸĶĩ

Deep Squatting

Repeated deep squatting or kneeling may contribute to meniscal loading in some individuals.

🔗

Combined Ligament Injury

Meniscus tears frequently occur alongside ACL injuries.

ðŸšĻ

Trauma

Falls, direct blows, or awkward landings may injure the meniscus.

RISK FACTORS

Who Is Most at Risk?

🏅

Athletes

Sports involving cutting, pivoting, and jumping.

ðŸ‘ī

Adults Over 40 Years

More likely to develop degenerative meniscal tears.

🔧

Manual Workers

Frequent kneeling, squatting, or lifting.

ðŸšĻ

Individuals with Previous Knee Injuries

History of ACL injury or previous meniscus injury.

ðŸĶī

People with Knee Osteoarthritis

Degenerative meniscal tears commonly occur alongside osteoarthritis.

🏃

Active Individuals

High training volumes and sudden changes in activity increase risk.

DIAGNOSIS

How Is It Diagnosed?

Clinical Assessment

Medical History

  • Twisting mechanism
  • Swelling
  • Locking
  • Clicking
  • Knee instability
  • Sporting activities
  • Previous injuries
  • Functional limitations

Physical Examination

  • Knee movement
  • Joint line tenderness
  • Swelling
  • Muscle strength
  • Walking pattern
  • Functional tasks such as squatting

Special Tests & Imaging

Special Tests

  • Thessaly Test
  • McMurray Test
  • Joint Line Tenderness Assessment
  • Apley's Compression Test
  • Ligament testing to exclude ACL or MCL injuries

No single test confirms a meniscus tear. Diagnosis is based on your history, examination findings, and clinical reasoning.

Imaging

X-rays do not show the meniscus but may help exclude fractures or osteoarthritis. MRI is the preferred imaging test when surgery is being considered, the diagnosis is uncertain, or persistent symptoms remain despite rehabilitation.

SEEKING HELP

When Should You Get Help?

ðŸŸĒ

Self-Management

Usually appropriate if:

  • Mild pain
  • Minimal swelling
  • Improving symptoms
  • Able to walk normally
ðŸŸĄ

Book a Physiotherapy Assessment

Recommended if:

  • Knee pain lasts longer than one week
  • Swelling persists
  • Pain during squatting or twisting
  • Difficulty returning to sport
  • Recurrent knee symptoms
ðŸ”ī

Seek Immediate Medical Attention

Seek urgent assessment if you experience:

  • A locked knee that cannot fully straighten
  • Obvious deformity
  • Inability to bear weight after injury
  • Severe swelling immediately after trauma
  • Fever with a swollen knee
  • Progressive numbness or loss of circulation

TREATMENT

Treatment Options

📚

Education

Understanding your injury and gradually returning to activity are key components of recovery.

🏋ïļ

Exercise Therapy

Progressive strengthening, balance training, and functional rehabilitation are considered first-line treatment.

🔄

Activity Modification

Reducing high-impact or twisting activities during the early stages allows symptoms to settle.

👐

Manual Therapy

Manual therapy may improve knee mobility and reduce pain when combined with exercise.

💊

Medication

Pain-relieving medication may be appropriate under medical supervision during the early stages.

💉

Injections

Injections are not routinely recommended for isolated meniscus tears.

ðŸĨ

Surgery

Arthroscopic surgery may be appropriate for true mechanical locking, certain displaced tears, or associated ligament injuries.

PHYSIOTHERAPY

How Physiotherapy Helps

Physiotherapy aims to reduce pain, restore knee movement, improve strength, and safely return you to work, sport, and daily activities.

Treatment may include:

  • Individualised strengthening programme
  • Quadriceps strengthening
  • Hamstring strengthening
  • Hip strengthening
  • Balance and proprioception training
  • Walking retraining
  • Running progression
  • Sport-specific rehabilitation
  • Return-to-sport testing
  • Long-term injury prevention

RECOVERY JOURNEY

Recovery Timeline

1
Week 1–2: Pain and swelling management, restoring knee movement, and gentle muscle activation.
2
Week 2–6: Progressive strengthening, improved walking, balance training, and return to everyday activities.
3
Week 6–12: Advanced strengthening, functional rehabilitation, and gradual return to recreational exercise.
4
Beyond 3 Months: Sport-specific rehabilitation, agility training, and return-to-sport testing. Recovery after meniscus repair surgery may take 4–6 months.

EXERCISE LIBRARY

Recommended Exercises

Heel Slides

Easy

Target: Knee mobility

Repetitions: 10–15

Quadriceps Sets

Easy

Target: Quadriceps activation

Hold: 5–10 seconds

Repeat: 10–15 times

Straight Leg Raise

Easy

Target: Quadriceps

Repetitions: 10–15 × 2 sets

Mini Squats

Moderate

Target: Quadriceps and gluteals

Repetitions: 10–15 × 2–3 sets

Step-Ups

Moderate

Target: Functional lower-limb strength

Repetitions: 10 each leg

Single-Leg Balance

Moderate

Target: Knee stability and proprioception

Hold: 20–30 seconds × 3 repetitions

Important: Exercise selection depends on the type of tear, symptom severity, and whether surgery has been performed. A locked knee or repairable tear may require activity restrictions and specialist guidance.

LONG-TERM HEALTH

Prevention Tips

💊

Strengthen the Legs

Strong quadriceps, hamstrings, and gluteal muscles help support the knee.

⚖ïļ

Improve Balance

Balance and neuromuscular training reduce the risk of knee injuries.

ðŸ”Ĩ

Warm Up Before Sport

Prepare the muscles and joints before training or competition.

📈

Progress Training Gradually

Avoid sudden increases in training intensity or volume.

ðŸĶĩ

Use Good Landing Technique

Learning proper jumping and cutting mechanics reduces knee stress.

✅

Complete Rehabilitation After Injury

Returning to sport before fully recovering increases the risk of reinjury.
