An articular cartilage injury is damage to the smooth cartilage covering the ends of bones in your joints, the layer that allows smooth, pain free movement. It can result from trauma, overuse, or degenerative conditions like osteoarthritis.
Symptoms include joint pain, swelling, and limited range of motion.
Treatment depends on the severity and location of the injury. Options range from conservative approaches like rest, physical therapy, and medication, to surgical interventions such as cartilage repair or transplantation.
Catching it early gives you more options and a better chance at a full recovery.
Let's debunk some common myths about articular cartilage injury.
Myth 1: Cartilage can repair itself
While cartilage has some capacity for repair, it has limited blood supply and healing potential compared to other tissues in the body. Severe cartilage damage often requires intervention to support the healing process.
Myth 2: Pain always indicates cartilage damage
Not all joint pain comes from cartilage injury. Pain can arise from a range of factors, including muscle strains, ligament injuries, and inflammation. A proper diagnosis is essential to identify the underlying cause.
Myth 3: Surgery is always required for cartilage injuries
Many cartilage injuries can be managed non surgically, through measures like physical therapy, medication, or injections. Surgery is typically reserved for more severe cases, or when conservative treatment options have not been effective.
Knowing fact from fiction puts you in a better position to make the right call for your joints.

Let's explore the causes of articular cartilage injury. Articular cartilage injuries can stem from various causes.
Direct impacts or trauma to the joints, such as falls, sports related injuries, or traffic accidents, can damage the cartilage. Sudden twisting or hyperextension of the joint can also lead to cartilage injury.
Repetitive stress on the joint from activities like running, jumping, or lifting heavy weights can gradually wear down the cartilage, leading to injury.
As people age, cartilage naturally becomes more susceptible to wear and tear, increasing the risk of injury and degenerative conditions like osteoarthritis.
A healthy weight, proper warm ups and cool downs, appropriate protective gear, and avoiding overuse are your best defences against all three.
Here are some of the main treatment options for articular cartilage injury.
A proper therapy program can strengthen the muscles around the joint, improve stability, and enhance range of motion. These exercises focus on improving joint function and reducing pain.
PRP therapy involves injecting concentrated platelets from the patient's own blood into the joint, which may help support tissue repair and reduce inflammation.
Over the counter pain relievers may help alleviate pain and reduce inflammation associated with a cartilage injury. In some cases, steroid injections may be recommended to provide temporary pain relief.
For more severe or persistent cases, surgical options such as microfracture surgery, cartilage transplantation, or arthroscopic procedures may be considered to repair or restore the damaged cartilage.
Recommended treatment depends on factors such as the severity of the injury, the patient's age and activity level, and overall health status.
Articular cartilage injuries can affect anyone, but they are more common in athletes and active individuals due to repetitive stress and high impact activities. Older adults are also at higher risk due to the natural wear and tear on cartilage over time.
Additional risk factors include previous joint injuries, obesity, genetic predisposition, poor joint alignment, and conditions like osteoarthritis.
Some of these you can't change, but a healthy weight, low impact exercise, and avoiding joint overuse are within your control.
Look out for clicking or grinding sensations in your knee. Diagnosing cartilage damage can be tricky, as symptoms often mimic sprains or ligament injuries.
Modern tests like MRI scans or an arthroscopic examination can make it easier to identify cartilage injuries. An MRI shows detailed images, while arthroscopy allows a doctor to see inside the knee with a tiny camera.
If you suspect you have a knee injury, it's advisable to seek medical treatment.
The sooner it's diagnosed, the more treatment options tend to stay on the table.
Here are three telltale signs your articular cartilage may be injured.
If you experience ongoing pain in the joint, especially during movement or weight bearing activities, it could indicate an articular cartilage injury. This pain may range from dull aches to sharp discomfort and may worsen over time.
Swelling around the joint, accompanied by stiffness, can indicate cartilage damage. The joint may feel puffy and warm to the touch, and have a limited range of motion, particularly after periods of rest or inactivity.
Sensations of the joint catching, locking, or giving way during movement can signal cartilage damage. This may be accompanied by audible clicks or pops when moving the joint, indicating loose cartilage fragments interfering with smooth movement.
Spotting these early makes it far easier to keep your knee moving the way it should.
