Patellofemoral arthritis
Patellofemoral arthritis is a common condition affecting the kneecap and can cause significant discomfort in the front of the knee. This knee pain often becomes more noticeable during activities like climbing stairs or walking uphill. Prolonged sitting, such as during long car rides or in tight theatre seats, can also exacerbate the discomfort.
What we know about patellofemoral arthritis
It’s estimated that 80% of individuals will have some degree of patellofemoral arthritis by the time they reach 80 years old. While some may feel pain, others may not even realise they have the condition. The patellofemoral joint endures more force than any other joint in the body, taking on four times the body weight when walking and eight times the weight when running. Certain exercises like squats and lunges can worsen symptoms for some, while cycling may offer relief. Individuals who experienced patella instability during adolescence could be at a higher risk of developing painful patellofemoral arthritis later on in life.
Treatments for patellofemoral arthritis
Non-operative management
To avoid undergoing surgery for a condition, you can alter your physical activity. For example, cycling might be more suitable than squats and lunges for some patients. Physiotherapy and injections could also be beneficial in specific circumstances.
Osteotomy joint preservation techniques
In some situations, it may be beneficial to use joint preservation methods. For example, if the arthritis is not severe or is only affecting specific areas, an osteotomy may be performed to reposition the kneecap and reduce pressure on the most impacted regions.
Partial knee replacement
If you are experiencing joint issues, a partial knee replacement could be a viable option to consider. Unlike a total knee replacement, this procedure replaces only the damaged portion of the joint, leaving the healthy parts intact. This approach could allow for a higher level of physical activity and preserve the knee’s ligaments. However, it’s important to note that if the remaining parts of the knee joint deteriorate, the issue may resurface. About 25% of partial knee replacements require a total knee replacement within 10 years. If you opt for this procedure, you may also be able to take advantage of a robotic-assisted knee replacement system during surgery.
Total knee replacement
If you are experiencing arthritis symptoms in multiple parts of your knee joint, a total knee replacement may be worth considering. Although this type of surgery is more involved than a partial knee replacement, it can offer effective relief and long-lasting benefits for your knee.
