Meniscus Tear: Causes, Symptoms and How Physiotherapy Can Help

A twist of the knee during a futsal match, a deep squat while gardening, or simply standing up awkwardly from a low chair – any of these can tear the meniscus, the crescent-shaped cartilage that cushions your knee joint. Meniscus tears are one of the most common knee injuries treated in Malaysia, affecting both young athletes and older adults. Recent research has revolutionised treatment, showing that physiotherapy is often as effective as surgery for many types of meniscus tears.

Understanding Your Meniscus

Each knee has two menisci – the medial meniscus on the inner side and the lateral meniscus on the outer side. These C-shaped wedges of fibrocartilage serve several critical functions: they absorb shock, distribute load evenly across the joint, provide stability, and lubricate the knee. Losing meniscal tissue – whether through injury or surgical removal – accelerates cartilage wear and increases the risk of developing osteoarthritis.

The meniscus has a unique blood supply pattern. The outer third (red zone) has a good blood supply and better healing potential, while the inner two-thirds (white zone) has limited blood supply, making natural healing more difficult.

How Meniscus Tears Occur

Meniscus tears fall into two broad categories based on their cause:

• Traumatic tears (younger patients) – A sudden twisting motion with the foot planted, common during futsal, football, and badminton. The force exceeds what the healthy meniscus can withstand
• Degenerative tears (older adults) – The meniscus weakens with age, and tears can occur with minimal force – sometimes from simply squatting or stepping off a curb. These are increasingly common in Malaysians over 40
• Combined with ligament injuries – Meniscus tears frequently accompany ACL injuries, particularly in contact sports
• Repetitive loading – Occupations requiring frequent squatting, kneeling, or heavy lifting gradually stress the meniscus over time

Signs That Point to a Meniscus Tear

Meniscus tear symptoms can vary in severity but typically include a distinctive pattern:

• Pain along the joint line – either the inner or outer edge of the knee, depending on which meniscus is torn
• Swelling that develops gradually over 24-48 hours after the injury (unlike ACL tears which swell within hours)
• Mechanical symptoms – the knee catching, locking, or giving way during movement
• Difficulty fully bending or straightening the knee, with a sensation of something blocking movement
• Pain when twisting or squatting, and when getting up from a seated position
• A popping or clicking sensation during knee movement

If you recognise these symptoms, it is important to seek professional assessment rather than trying to self-diagnose. Many conditions share similar symptoms, and an accurate diagnosis is crucial for effective treatment.

Surgery Versus Physiotherapy: What the Evidence Shows

This is one of the most important decisions you will face with a meniscus tear. Recent high-quality research has changed the treatment landscape significantly:

For degenerative meniscus tears in patients over 40, multiple randomised controlled trials have shown that physiotherapy produces outcomes equal to arthroscopic surgery. This finding has led international guidelines to recommend physiotherapy as the first-line treatment for degenerative tears, reserving surgery for cases that do not respond to 3-6 months of focused rehabilitation.

For traumatic tears in younger, active patients, surgery (meniscus repair or partial meniscectomy) may be more appropriate, particularly for tears in the vascularised outer zone, locked knees, or tears associated with ACL reconstruction. Even in surgical cases, physiotherapy is essential before and after the procedure.

The Physiotherapy Rehabilitation Programme

Acute Phase (Weeks 1-2)

The initial focus is on reducing swelling, managing pain, and restoring knee extension:

• RICE protocol (Rest, Ice, Compression, Elevation) combined with gentle range of motion exercises
• Quadriceps activation exercises to prevent muscle shutdown, which occurs rapidly after knee injury
• Gentle patella mobilisation to maintain knee cap mobility

Rebuilding Phase (Weeks 2-8)

• Progressive quadriceps strengthening – From straight leg raises through to squats, leg presses, and step-ups
• Hamstring and hip strengthening – Building the supporting muscles that reduce load on the meniscus
• Proprioception training – Balance exercises on unstable surfaces to retrain the knee's position sense
• Cardiovascular fitness – Cycling and swimming to maintain fitness without excessive knee loading

Return to Activity Phase (Weeks 8-12+)

• Sport-specific drills – Agility, cutting, and pivoting exercises for athletes returning to futsal, football, or badminton
• Plyometric training – Jumping and landing exercises to prepare the knee for high-impact activities
• Functional testing – Objective assessment of strength, balance, and movement quality before clearance for full activity

Protecting Your Meniscus Long-Term

• Maintain strong quadriceps and hip muscles – they absorb forces that would otherwise load the meniscus
• Warm up thoroughly before sports, paying attention to dynamic stretches and movement preparation
• Maintain a healthy weight – excess body weight significantly increases meniscal stress during daily activities
• Wear appropriate footwear with good support for your chosen activity
• Avoid deep squatting or kneeling for prolonged periods, particularly if you have early meniscal degeneration

A meniscus tear does not automatically mean surgery. With the right physiotherapy approach, many patients achieve excellent outcomes and return to full activity.
