Meniscal Injuries of the Knee
Meniscal injuries of the knee are among the most common causes of knee pain in Australia.
Below we explore how meniscal injuries occur, what symptoms to look out for, and the treatment options available.
Whether caused by sports, work-related activity, or gradual wear and tear, a torn meniscus can affect your movement, stability, and overall quality of life.
While some injuries resolve with rest and rehabilitation, others may require specialist input.
Understanding the nature of meniscal damage and the available management options is a key step in making informed decisions about your health.
What Is the Meniscus?
The meniscus is a curved pad of cartilage found in each knee. You have two menisci in each knee—the medial (inside) and lateral (outside)—which are located between the thigh bone (femur) and the shin bone (tibia).
Their main roles include:
- Shock absorption during weight-bearing activities
- Joint stability, especially during twisting or pivoting
- Load distribution to minimise pressure on the bones
- Lubrication and nutrition of the knee joint
Meniscal injuries happen when this cartilage becomes damaged, either through sudden trauma or gradual wear. They are often associated with sports that involve pivoting or rapid direction changes, though age-related degeneration can also lead to tears over time.
Damage to the meniscus can also affect how your knee joint handles weight over time, potentially leading to uneven joint wear and contributing to osteoarthritic changes if left unmanaged.
Common Causes of Meniscal Injuries
Meniscal tears can affect people of all ages, but are particularly common in two groups:
- Young and active individuals, where injuries are usually due to trauma or twisting motions (e.g. during football, netball, or skiing)
- Older adults, where the cartilage becomes weaker and more prone to tearing from routine movements, often due to osteoarthritis
Other contributing factors may include:
- Repetitive kneeling or squatting (common in trades or gardening)
- Previous knee injuries
- Age-related cartilage degeneration
- Poor joint alignment or biomechanics
- High body mass index (BMI), which may increase the mechanical load on the knee joint
- Weakness or imbalance in surrounding muscles, particularly the quadriceps and hamstrings
Symptoms of a Meniscal Tear
The type and intensity of symptoms often depend on where the tear is located and how extensive the damage is. Some people may not notice the injury immediately. Common signs include:
- Pain on one side of the knee
- Swelling that may appear several hours after injury
- Catching, locking, or clicking of the knee joint
- Difficulty fully straightening or bending the knee
- A feeling that the knee is giving way
In degenerative tears, symptoms may be milder and develop gradually over weeks or months, making them harder to detect early.
In some cases, symptoms may settle with rest, but they can return with activity or worsen over time.
Diagnosis: How Meniscal Injuries Are Assessed
If you suspect a meniscal injury, your GP or physiotherapist may begin with a physical examination to assess joint movement, swelling, and tenderness. They may refer you to imaging studies, such as:
- MRI scans: High-resolution views of the cartilage and soft tissues inside the knee, aiding accurate diagnosis
- X-rays: Used to rule out associated bone changes (e.g. osteoarthritis)
- Diagnostic arthroscopy: A minimally invasive procedure using a small camera, considered if the clinical picture remains unclear after non-invasive imaging
Diagnosis may also involve considering alternative sources of knee pain, such as ligament injuries or patellofemoral issues.
Non-Surgical Management Options
Not all meniscal injuries require surgery. In many cases, conservative management can be effective, particularly for smaller or degenerative tears. Treatment may include: Read More
- Reducing or modifying certain activities to ease inflammation and support recovery
- Ice therapy in the early stages to manage swelling
- Physiotherapy to strengthen surrounding muscles and improve joint stability
- Anti-inflammatory medications, if advised by your doctor
- Knee braces or supportive taping to offload pressure from the joint during recovery
Adherence to a structured physiotherapy program is a key factor in achieving symptom relief and functional recovery. Your health provider may tailor exercises based on your occupation or activity level.
Recovery time depends on several factors, including the tear’s nature, your age, lifestyle, and overall physical condition. Some people return to regular activity within weeks, while others may require longer rehabilitation.
When Surgery Might Be Considered
Surgical intervention is generally considered only when non-surgical treatments have not provided sufficient relief or when the tear significantly disrupts day-to-day movement or stability.
Surgical treatment may be considered if:
- The tear is large or causing persistent mechanical symptoms (e.g. locking or catching)
- Non-surgical management has not improved your symptoms
- There is associated ligament damage or instability
- You are a younger or active individual with a tear that may heal well with repair
Common procedures include:
- Arthroscopic meniscectomy: Trimming and removing the damaged part of the meniscus
- Meniscal repair: Stitching the torn cartilage to allow healing, usually reserved for peripheral tears with good blood supply
- Meniscal transplant: Considered in selected cases for individuals with previous total meniscus removal and ongoing joint pain
As with all procedures, outcomes can vary. Surgical decisions should be made in consultation with an orthopaedic specialist or a knee specialist in Sydney, depending on your location and clinical needs.

Recovery and Rehabilitation After Surgery
Rehabilitation plays a central role in recovery, whether or not surgery is part of the treatment. It helps restore knee strength, stability, and confidence in movement.
Rehabilitation is a crucial part of recovery, whether surgery is performed or not. Your plan may involve:
- Gradual return to weight-bearing activities
- Range-of-motion exercises to restore flexibility
- Strength training targeting the quadriceps, hamstrings, and gluteal muscles
- Proprioception exercises to improve joint awareness and balance
- Guidance from a physiotherapist on returning to work or sport safely
Recovery timelines differ between procedures. For example, meniscectomy patients may return to low-impact activity within weeks, while meniscal repairs require longer rehabilitation to protect the healing tissue.
It's also important to follow post-operative guidelines closely, including any restrictions on movement or weight-bearing, to reduce the risk of re-injury or delayed healing.
Can Meniscal Injuries Be Prevented?
Although it’s not always possible to avoid knee injuries entirely, adopting protective habits can help lower your risk:
- Maintaining strong, flexible leg muscles through regular exercise
- Warming up properly before sport or physical activity
- Using appropriate footwear with good support
- Avoiding sudden changes in direction on uneven surfaces
- Managing joint conditions like osteoarthritis with guidance from your GP or allied health team
Incorporating balance and proprioception training into your routine may also help prevent future injuries, especially if you've previously sustained a knee injury.
If you work in a physically demanding role, using correct lifting techniques and taking regular breaks can help protect your knees.
Long-Term Considerations
Untreated or chronic meniscal injuries may contribute to:
- Ongoing knee pain and swelling
- Reduced joint function or instability
- Early development of osteoarthritis in the affected knee
Meniscal injuries that are not addressed appropriately can contribute to joint stiffness, reduced mobility, and difficulty maintaining an active lifestyle.
Early assessment and personalised management can help preserve knee health and function. If you begin to experience new symptoms or notice that existing ones are getting worse, it's important to consult your GP or another qualified healthcare provider—particularly as some changes may reflect the warning signs of knee arthritis rather than the meniscal injury alone.
Speak With a Registered Health Practitioner
If you're experiencing symptoms consistent with a meniscal injury, it’s important to get assessed by a medical professional. A physiotherapist, general practitioner, or orthopaedic expert, such as a knee surgeon, can assess your condition and recommend the most appropriate next steps.
