Treating Knee Tears in Adelaide
Meniscus & Cartilage Damage
The meniscus and the surrounding joint cartilage act as the fundamental structural foundations for smooth, pain-free knee movement. Damage to these tissues can cause significant physical discomfort, localised swelling, and mechanical issues like catching or locking.
At Adelaide Knee Clinic, led by Adelaide orthopaedic surgeon Dr Matthew Liptak, we provide expert assessment and individualised treatment pathways for both acute traumatic tears and age-related wear.
What is Meniscus and Cartilage Damage?
To understand knee function, it is helpful to distinguish between these two different types of protective tissue inside the joint:
- The Meniscus: Each knee has two C-shaped discs of tough, rubbery fibrocartilage (the medial and lateral meniscus) that sit between your thighbone and shinbone. They act as essential shock absorbers, distributing body weight evenly across the joint and providing stability.
- Articular Cartilage: This is the ultra-smooth, slippery lining covering the ends of the bones inside the knee joint. It allows the bones to glide over one another seamlessly with minimal friction.
When a meniscus tears or the articular cartilage is damaged, the smooth mechanics of the knee are disrupted, which can cause accelerated joint wear over time if left unmanaged.
Who Suffers Meniscus and Cartilage Tears?
Knee cartilage issues generally fall into two broad categories based on how the injury occurs:
Acute Traumatic Tears
These are common in athletes and active individuals. They frequently occur during sports that require sudden pivoting, twisting, cutting, or direct contact—such as football, netball, soccer, and basketball. A sudden twist while the foot is firmly planted can cause the meniscus to pinch and tear.
Degenerative Wear and Tears
As we get older, the cartilage inside the knee naturally loses its elasticity and becomes more brittle. Degenerative meniscus tears can occur with very minimal stress, such as squatting down, getting out of a low chair, or tripping slightly on an uneven surface. This type of damage is often closely linked to early stages of knee osteoarthritis.
Symptoms and Diagnosis
Common Symptoms
The signs of a meniscus or cartilage injury depend heavily on the size and location of the tear. You may experience:
- Pain Along the Joint Line: Persistent discomfort felt specifically on the inner or outer side of the knee joint.
- Swelling and Stiffness: Delayed swelling that typically develops over 24 to 48 hours following an injury or flare-up.
- Mechanical Catching or Locking: A physical sensation that something is stuck inside the knee, occasionally preventing you from fully straightening or bending the joint.
- Instability: A feeling that the knee is weak or may suddenly give way under your weight.
Reaching an Accurate Diagnosis
A precise evaluation ensures that minor tears are managed properly before they lead to broader joint wear. The diagnostic process includes:
- Clinical Examination: Physical tests designed to gently manipulate the joint and check for localised tenderness or mechanical clicks.
- MRI Scanning: While standard X-rays are helpful to check for bone spurs or osteoarthritis, an MRI is the standard tool required to clearly visualise the soft tissues, confirm a meniscus tear, and evaluate the depth of cartilage damage.
Treatment Options for Meniscus & Cartilage Damage
Your treatment pathway is tailored entirely to the type of tear, your baseline activity levels, and whether the knee is experiencing mechanical blockages.
1. Non-Surgical Rehabilitation
Many meniscus and cartilage tears in particular degenerative tears or small stable tears on the outer edge of the meniscus may heal well or become symptom-free without surgery:
- Activity Modification: Temporarily reducing high-impact, twisting activities to allow localised inflammation to settle.
- Targeted Physiotherapy: Exercises designed to strengthen the quadriceps, hamstrings, and calves, improving joint tracking and reducing the raw mechanical load placed directly on the damaged area.
- Anti-inflammatory Management: Short-term use of over-the-counter pain relief or anti-inflammatory medications under medical guidance to manage structural flare-ups.
2. Specialist Surgical Options
If conservative management fails to resolve your symptoms, or if the knee is actively catching and locking, a surgical review with an orthopaedic surgeon is advised:
