What is Meniscal Degeneration?

Meniscal degeneration refers to the gradual wear and breakdown of the cartilage pads, called menisci, inside the knee joint. Each knee has two menisci that act as shock absorbers between the thigh bone (femur) and the shin bone (tibia). Over time, these structures can weaken, fray, or split, leading to pain, swelling, and reduced function.

This condition is common in adults over 40 and often occurs without a single traumatic event. It is linked to age-related changes, repetitive strain, and poor joint mechanics. Meniscal degeneration can coexist with osteoarthritis or appear after previous knee injuries.

What Happens in Meniscal Degeneration?

In healthy knees, the menisci distribute load evenly through the joint and protect the cartilage. When degeneration begins, the meniscus loses water content and elasticity. Small cracks can form and eventually split through the tissue. As the meniscus loses its shape, it can no longer cushion impact effectively.

This may cause pain, swelling, and a catching or locking sensation during movement. In advanced cases, fragments can irritate the joint lining, worsening inflammation and stiffness.

Common Causes of Meniscal Degeneration

  • Aging and gradual wear
  • Repetitive kneeling, squatting, or twisting
  • Previous ligament injury, such as ACL rupture
  • Poor lower limb alignment and weak hip or thigh muscles
  • Overweight or obesity increases joint load
  • Genetic factors and family history of joint problems

Who is Most Affected?

  • Adults over 40
  • Workers in physical trades and manual jobs
  • Recreational athletes such as footballers, runners, and netball players
  • People with a history of knee injury or surgery
  • Individuals with early knee osteoarthritis

Symptoms of Meniscal Degeneration

  • Pain along the joint line of the knee
  • Swelling that worsens after activity
  • Stiffness or a feeling of fullness inside the joint
  • Clicking, catching, or locking
  • Difficulty kneeling or squatting
  • Reduced ability to twist or pivot

📞 If your knee feels painful, stiff, or unstable, book an assessment at Spinal and Sports Care Bella Vista or Parramatta.

Diagnosis of Meniscal Degeneration

Clinical Tests

  • Joint line tenderness and pain on compression or twisting
  • Swelling after activity or prolonged sitting
  • Decreased range of motion
  • Functional strength testing of quadriceps and hamstrings

Imaging

  • MRI: the most reliable method to assess meniscal damage, thickness, and tears.
  • X-ray: helps rule out arthritis or bony change.
  • Ultrasound: useful for detecting joint fluid and inflammation.

📞 Spinal and Sports Care can arrange MRI or imaging referrals and complete a full knee assessment.

Treatment Options

Treatment depends on age, activity level, and the severity of degeneration.

Non-Surgical Management

  • Physiotherapy: strengthens supporting muscles, restores alignment, and improves joint control.
  • Chiropractic care: restores joint mobility and reduces stiffness through gentle adjustments.
  • Exercise therapy: low-impact strength and stability training.
  • Anti-inflammatory medication as prescribed by a GP.
  • Weight management to reduce knee load.
  • Injections: cortisone for short-term relief or PRP for tissue healing in selected cases.

Surgical Management

  • Arthroscopy: used to trim unstable fragments or smooth frayed edges. Results vary with age and degeneration severity.
  • Meniscal repair: less common in degenerative tears.
  • Joint replacement: considered only in advanced arthritis cases.

Role of Physiotherapy and Chiropractic Care

  • Reduce pain and swelling.
  • Strengthen quadriceps, hamstrings, and glutes.
  • Restore mobility through joint and soft tissue techniques.
  • Correct lower limb biomechanics and gait.
  • Guide return to sport or work safely.

Recovery Timeline

  • Mild degeneration: improvement within 6–8 weeks with guided exercise.
  • Moderate degeneration: 8–12 weeks of progressive rehabilitation.
  • Post-surgical: 3–6 months depending on the procedure.

Prevention of Meniscal Degeneration

  • Maintain a healthy weight.
  • Keep thigh and hip muscles strong.
  • Avoid deep repetitive squatting and twisting.
  • Address knee injuries promptly.
  • Include mobility and balance training in exercise routines.

Frequently Asked Questions

It is the gradual wear and weakening of the cartilage pads that cushion the knee joint.

Degenerative tears occur slowly from wear, not from sudden trauma.

Pain along the joint line, swelling, stiffness, and catching or locking.

Yes. Low-impact strengthening and cycling help support the joint.

Not usually. Most people improve with physiotherapy and strength work.

Yes. Gentle adjustments and soft tissue techniques can reduce stiffness and improve mobility.

Between 6 and 12 weeks for most mild or moderate cases.

The meniscus does not fully heal, but symptoms can be well controlled.

Swimming, cycling, and controlled gym exercises are the best activities.

If pain, stiffness, or swelling lasts more than six weeks or limits your daily activity, consult a doctor, physio or chiro.
