  • Patella Dislocation

    Patellar subluxation is a partial dislocation of the kneecap (patella). It’s also known as patellar instability or kneecap instability. The kneecap is a small protective bone that attaches near the bottom of your thigh bone (femur)

  • Treatment Options For Knee Pain Associated to Articular Cartilage Damage

    When doctors contact patients with articular cartilage problems in the knee, usually what they hear about is swelling in the knee, pain, and limitations in function, and that can be in simple everyday activities, or it can be limitations in more advanced activities like sports and work-related function.


    Each situation is unique and that’s important to remember, and a lot of what patients have to tell their physician relates to where they’re coming from in terms of their physiological age, their chronological age, their lifestyle, and what their expectations are, and where they want to return.

    The treatment options for cartilage problems in the knee depends on various aspects. There’s patient specific factors that we talked about such as age, activity level, function, expectations, and there is actual cartilage defect specific factors that we consider; for example, how big is the cartilage lesion, where is the cartilage lesion location, and does the cartilage lesion occur by itself or in combination with other problems in the knee joint; for example, ligament problems, meniscus problems, and the overall alignment of the entire extremity.

    You have to remember what happens in the knee is often a direct result of what happens both above and below. So above we have the hip, the pelvis, and the core muscles, and below we have the foot, and the ankle. So overall you have to consider the overall patient in terms of anatomy, in terms of a cartilage lesion, and in terms of where they’re coming from as an individual.

    For the young patient with a lesion in the cartilage that limited to one area, and the rest of their knee is in relatively good shape, there’s actually a lot of options, and the options range anywhere from non-operative treatment that can include injections, such as cortisone, hyaluronic acid, and maybe even platelet rich plasma, all the way to more advanced option, such as unloader braces and physical therapy.

    From the surgical side, you have micro fracture, you have other newer treatments like De Novo, which is an allograft or cartilage where donors who have passed away have donated their cartilage so recipients with the appropriate pathology can be treated.

    Other alternatives include receiving other types of transplants or cartilage transplants, and in certain parts of the world you can be treated with your own cartilage cells where the cartilage is biopsied, it’s grown in the lab and re-implanted into your knee, and that procedure is called autologous chondrocyte transplantation.

    We don’t have that in Canada, but in the United States and Europe it’s widely available. If you’re an individual who has cartilage disease either spread out through the entire knee or a very advanced disease that’s very large and involved both sides of the joint, focal cartilage treatments, such as the ones I’ve talked about may not be appropriate for you. In your situation, you may be better managed with injections.

    Once again, in the various types we’ve talked about: braces, physical therapy, and more invasive surgical alternatives, and these include things, such as an osteotomy of your knee, a partial knee replacement, or even a total knee replacement. So ultimately decide what treatment is best for you, and where you fall into the spectrum of cartilage pathology, you need to be evaluated. Often seeing a local family physician or a physiotherapist in conjunction with a registered dietitian and athletic therapist is a great option to take control of this condition. Smart Food Now and exercise is also optominal for overall health.    

    If you think what we’ve talked about today applies to you, please contact your primary care physician for a referral to the appropriate specialist or orthopedic Surgeon .
