Cartilage damage seriousness varies from minor softening to severe, full-depth defects, but it's generally serious because cartilage lacks blood supply and can't heal itself, leading to pain, swelling, stiffness, and if untreated, progressive osteoarthritis, potentially requiring surgery or joint replacement. Severity depends on the defect's size and depth, with larger injuries posing greater risks for worsening symptoms like joint locking or immobility.
Simply, no. In most cases, surgery is required to repair articular cartilage. In rare cases, small traumatic cartilage lesions form a repair tissue called fibrocartilage on their own. This typically occurs at the time of injury if there is a significant amount of bleeding and trauma.
More severe cartilage damage probably won't improve on its own. If left untreated, it can eventually wear down the joint. Visit your GP or an urgent and emergency care service if: you can't move the joint properly.
Unlike muscles or skin, cartilage has a very limited blood supply. That means once it's injured, it doesn't regenerate easily—and untreated damage can get worse over time, leading to chronic pain or even arthritis.
What are symptoms of cartilage damage in the knee?
Through the ability of magnetic resonance imaging (MRI) to characterize soft tissue noninvasively, it has become an excellent method for evaluating cartilage. The development of new and faster methods allowed increased resolution and contrast in evaluating chondral structure, with greater diagnostic accuracy.
Glucosamine (G) 1,500 to 2,000 mg/d and chondroitin sulfate (Cs) 800 to 1,200 mg/d and avocado-soy unsaponifiables (ASU) 300 to 600 mg/d, taken together or alone, are useful as adjunct therapies in cartilage disorders. Each is sold as prescription, over the counter (OTC), or as supplements, depending upon the country.
NYU Langone doctors often recommend nonsurgical options as a first-line treatment for a knee cartilage injury. These include anti-inflammatory medication, physical therapy, and injections into the joint, including steroids; hyaluronic acid, also known as synthetic joint fluid; and platelet-rich plasma (PRP).
For small or moderate meniscus tears, walking may still be possible, but excessive walking or prolonged standing could worsen pain and inflammation.

Imaging Tests
Your doctor may order an X-ray to create images of the knee bones and to rule out other causes of your symptoms, such as fractures or degenerative osteoarthritis. An MRI, which creates images of soft tissues, helps your doctor determine whether you have an acute injury to the knee cartilage.
Surgery is often the best treatment option for damaged articular cartilage since it does not heal well on its own. Some surgeries aim to relieve symptoms, while other surgical procedures are intended to repair and restore damaged articular cartilage.
Did you know cartilage damage doesn't heal on its own and could get worse and more painful if not addressed early? And if left untreated, knee cartilage damage can become so chronic that it can impact your active lifestyle. That's why it is critical to address your knee cartilage damage as soon as possible.
Painful catching or clicking sensations. Swelling – usually immediately or within 2 hours of the injury. Inability to fully straighten the knee. Inability to weight bearSigns of a more serious injury are immediate severe swelling into the knee and difficulty walking or inability to fully straighten the knee.
Physical stimuli (cyclic strain, electricity, electromagnetism, ultrasound, shock wave and laser) have already shown active roles in bone and cartilage regeneration in vitro and in vivo [19–23].
As mentioned earlier, people require cartilage restoration surgery when their cartilage becomes damaged, whether it's due to natural causes or injury. Getting the surgery is not only good because it will relieve pain, but it will also improve the range of motion and help delay and even prevent arthritis.
These medications reduce inflammation and relieve pain. Examples of NSAIDs include diclofenac, ibuprofen and naproxen. Two other anti-inflammatory painkillers with a similar effect are celecoxib and etoricoxib. These are COX-2 inhibitors (also known as coxibs).
A chronic meniscus injury will usually require complete rest, and there should be no weight-bearing on them at all. Smaller tears may benefit from aerobic exercise, but this should only be conducted under the recommendation of a health professional.
Vitamin D has been associated with cartilage regeneration in OA, but the exact mechanism is not well defined. Vitamin D deficiency is associated with an increased risk of patients developing OA in some studies, but the results of other studies have been inconsistent.
Symptoms of cartilage injuries include:
Controlled, repetitive low-impact loading exercises stimulate cartilage repair and strengthening. Recommended exercises include cycling, elliptical training, rowing, and moderate walking. Avoid high-impact activities like running and jumping that can damage cartilage.
Cartilage, a connective tissue in the body, has no blood or nerve supply to nourish the growth of new tissues, and no innate ability to heal. CartiHeal™ Agili-C™ is an implant intended to repair damaged cartilage. It is absorbed by the body and is a new treatment option for patients.
In terms of cartilage regeneration and relieving OsteoArthritis symptoms, numerous studies imply that the compounds in green tea like catechins and polyphenols, which help with other conditions, may also be important to protecting and restoring cartilage.
There is no cure for knee osteoarthritis (KOA) and typically patients live approximately 30-years with the disease. Most common medical treatments result in short-term palliation of symptoms with little consideration of long-term risk.
