Meniscus Tear

Meniscus Tear Symptoms, Common Causes and Treatments

What Is the Function of the Meniscus?

The meniscus is a crescent-shaped fibrocartilage structure located inside the knee joint. Each knee contains two menisci — one on the medial (inner) side and one on the lateral (outer) side. The meniscus plays several essential roles in knee function, including:

  • Distributing load across the knee joint to reduce stress on the articular cartilage
  • Absorbing shock to protect the knee during impact activities
  • Enhancing joint stability
  • Allowing smooth and efficient knee movement during activity

During activities such as walking, running, squatting, turning, and jumping, the meniscus is subjected to repeated loading. As a result, injury to the meniscus can significantly affect knee function and daily activities.

Common Causes of Meniscus Tears

Meniscus tears are among the most common knee injuries and are generally classified into two main types:

Traumatic Meniscus Tears

Traumatic meniscus tears are more commonly seen in physically active individuals and athletes. The typical injury mechanism involves a twisting or rotational movement while the knee is partially bent and weight-bearing. These injuries often occur during:

  • Sudden changes of direction or pivoting

  • Rapid deceleration or cutting movements

  • Poor landing mechanics during jumping

  • Sports such as football, basketball, badminton, rugby, and similar activities

Degenerative Meniscus Tears

With increasing age, the meniscus gradually loses elasticity and load tolerance. As a result, tears may occur even during everyday activities such as squatting, standing up, or minor twisting movements. Degenerative meniscus tears are more common in middle-aged and older individuals.

Meniscus tears also frequently occur alongside injuries to the anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL).

Symptoms of a Meniscus Tear

Symptoms of a meniscus tear vary depending on the location, size, and type of tear. Common symptoms include:

  • Knee joint swelling (which may appear immediately or develop later)
  • Knee pain, especially during squatting, twisting, or stair climbing
  • Reduced knee range of motion
  • Sensation of the knee “catching,” “locking,” or inability to fully straighten or bend
  • Localised tenderness along the joint line
  • A popping sound or sensation during injury or movement

In some individuals, symptoms may be mild initially but gradually worsen as activity levels increase, leading to increasing pain and functional limitations.

Risk Factors for Meniscus Tears

Several factors may increase the risk of sustaining a meniscus tear, including:

  • Participation in sports involving frequent pivoting, squatting, or jumping

  • Insufficient thigh or hip muscle strength

  • Reduced knee stability, such as a history of ACL injury

  • Excess body weight increasing joint loading

  • Age-related degenerative changes

Can a Meniscus Tear Cause Long-Term Problems?

If a meniscus tear is not properly managed, it may lead to:

  • Reduced knee stability

  • Decreased shock-absorbing capacity of the joint

  • Recurrent pain or swelling during activity

  • An increased risk of developing knee osteoarthritis over time

For this reason, early assessment and appropriate treatment are essential to minimise long-term complications and protect knee health.

Diagnosis of a Meniscus Tear

The diagnosis of a meniscus tear usually includes:

  • Clinical examination: Specific tests are used to assess pain, locking or catching sensations, and knee stability.

  • Magnetic Resonance Imaging (MRI): Used to confirm the location and type of the tear, and to identify whether other structures are also involved (such as the ACL or articular cartilage).

  • X-ray examination: Mainly used to rule out fractures or significant degenerative changes.

Treatment Options for Meniscus Tears

The management of a meniscus tear requires an individualised assessment rather than a one-size-fits-all approach. Physiotherapists consider multiple factors, including the location and type of the tear, the patient’s age, daily functional and sporting demands, and the severity of current symptoms. This comprehensive evaluation helps determine the most appropriate treatment pathway to restore knee function safely and effectively, while minimising the risk of long-term complications or re-injury.

Non-Surgical Management (Conservative Treatment)

Not all meniscus tears require surgery. Physiotherapy can usually be considered first in the following situations:

  • The tear is located in an area with better blood supply

  • The tear is mild in severity or is an incomplete tear

  • There is no significant displacement of the meniscus

  • Symptoms can be effectively controlled through rehabilitation training

The goals of physiotherapy include:

  • Reducing swelling and relieving pain

  • Restoring normal knee joint range of motion

  • Strengthening the quadriceps, hamstrings, and hip muscle groups

  • Improving balance, proprioception, and movement control

Surgical Management

In some cases, if the knee repeatedly catches or locks, symptoms significantly affect daily activities or sports performance, or there is no improvement after a period of conservative management, further medical assessment may be considered, including whether surgical intervention is appropriate. Common surgical options include meniscus repair or partial meniscectomy. Physiotherapists work closely with patients and the medical team both before and after surgery to support a safe and effective return of knee function.

Prehabilitation Before Meniscus Surgery

If surgery is required, preoperative physiotherapy (prehabilitation) can help improve postoperative rehabilitation outcomes.

The goals of prehabilitation include:

  • Reducing pain and swelling

  • Restoring normal knee joint range of motion

  • Improving lower limb strength and stability

  • Establishing a strong foundation for postoperative rehabilitation

Postoperative Rehabilitation and Return-to-Sport After Meniscus Surgery

Postoperative rehabilitation and return-to-sport planning after meniscus surgery vary depending on the type of surgery and individual recovery progress. However, the overall principle is a gradual and progressive approach. In the early stage of rehabilitation, the main goals are to control swelling, restore knee joint range of motion, and regain a normal walking pattern. The middle stage focuses on rebuilding lower limb strength and endurance. In the later stage, movement control, jumping, cutting, and sport-specific training are introduced to prepare for a safe return to sport.

In terms of recovery timeline, mild meniscus tears managed with physiotherapy can generally expect gradual recovery within approximately six to eight weeks.
After meniscus repair surgery, the overall rehabilitation period is usually around three to six months.
Following partial meniscectomy, recovery time is relatively shorter, typically around three to six weeks.

Before considering a return to sport, patients should ensure that knee joint range of motion has returned to normal, lower limb strength is close to symmetrical between both sides, there is no significant knee pain or swelling, and both movement control and psychological readiness have been achieved, in order to effectively reduce the risk of re-injury.

Frequently Asked Questions (FAQ)

Not necessarily. Not all meniscus tears require surgery. If the tear is mild, located in an area with better blood supply, or if symptoms do not significantly affect daily activities or sports performance, many patients can improve pain, restore function, and safely return to activity through appropriate physiotherapy.

Some mild or degenerative meniscus tears may experience gradual symptom improvement with appropriate rest and physiotherapy. However, if persistent catching, locking, or recurrent swelling occurs, professional assessment should be sought early to avoid delayed treatment.

High-impact activities or sports involving frequent turning should be avoided before symptoms are well controlled and function is restored. Once knee range of motion, strength, and movement control reach a safe level, physiotherapists will gradually introduce running and sport-specific training to ensure a safe return to exercise.

If a meniscus tear is not properly managed, it may impair the knee’s shock absorption and stability over time, increasing the risk of future joint degeneration or chronic knee pain. Therefore, early assessment and appropriate rehabilitation are very important.

If the knee experiences persistent pain, swelling, catching sensations, instability, or significant limitations in daily activities or sports, it is recommended to consult a physiotherapist early for professional assessment and to develop an appropriate rehabilitation plan to prevent worsening of the condition.

Testimonials & Reviews

After suffering years of chronic knee issues after ACL reconstructive surgery I was recommended to this clinic and the results were amazing. The centre does not only focus on pain relief but with an extremely holistic approach, assesses the root cause of pain and focuses on return to sports and performance once the pain diminishes. Most physiotherapy centres in Hong Kong do not even offer this level of attention to detail and service and would highly recommend to anyone having chronic pains or want to have proper post orthopaedic surgery rehabilitation!

I first found Mobilize Physio through Google after undergoing a two-level microdiscectomy at just 18. The surgery left me with significant leg damage due to severe sciatica and partial paralysis, and I needed to rebuild my strength and confidence to walk and play sports again.

Having Avery as my physiotherapist made a world of difference. He was incredibly patient, knowledgeable, and always took the time to educate me throughout our sessions which meant a lot since I hope to become a physiotherapist myself. Whenever I had extra questions, he was always there to answer them.

Over time, my legs started to feel normal again as I regained strength and mobility, and Avery helped me rebuild not only my body but also my confidence. I’m truly grateful for his help and would highly recommend him to anyone dealing with pain or recovering from surgery.
