Pain around the kneecap (patella) is one of the most common knee complaints. It can affect people of all ages, athletes and runners, as well as those with more sedentary lifestyles. The discomfort may be sharp or aching, occasional or persistent, and can be aggravated by activities such as climbing stairs, squatting, or sitting for long periods.
Kneecap pain is usually the result of a combination of biomechanical stress, overuse, or underlying structural problems. Here we’ll explore the different causes, alongside the treatments available.
Common causes of kneecap pain
One of the most frequent causes is patellofemoral pain syndrome, where the kneecap doesn’t move smoothly within its groove. This leads to irritation of the cartilage and surrounding tissues, often presenting as a dull ache at the front of the knee. It’s particularly common in runners and those who increase their activity levels quickly.
Patellar tendinopathy, sometimes referred to as jumper’s knee, is another common condition. This occurs when the tendon connecting the kneecap to the shinbone becomes overloaded, leading to pain just below the patella. It’s often seen in sports involving jumping, or repeated acceleration and deceleration.
Patella maltracking or instability, where the kneecap shifts out of alignment, increases pressure on certain parts of the joint and can lead to pain or even dislocation.
Other causes include cartilage damage, where the smooth surface lining the joint becomes worn or injured. Also, early osteoarthritis can be another cause of kneecap pain, usually in older patients or those with a history of knee injury. Less commonly, conditions such as bursitis or fat pad irritation, can also be responsible for pain around the kneecap.
Biomechanics play a key role
The way your body moves has a significant influence on the kneecap. Factors such as muscle strength, joint alignment, and movement patterns, all affect how forces are distributed across the patellofemoral joint.
Weakness in the quadriceps or hip muscles can allow the knee to drift inward during activity, increasing stress on the kneecap. Tight structures, such as the iliotibial band, can pull the patella off course, contributing to maltracking. Foot posture and running technique may also influence how load is transferred through the knee.
Over time, these small imbalances can lead to irritation, inflammation, and eventually structural changes within the joint. Addressing these underlying biomechanical issues is therefore central to both treatment and prevention.
Can you return to sport after kneecap cartilage damage?
Cartilage damage around the kneecap can be particularly challenging, especially for athletes who rely on explosive movement and high levels of knee function. However, advances in cartilage restoration techniques have significantly improved outcomes.
One such procedure is matrix-induced autologous chondrocyte implantation (MACI), which involves using a patient’s own cartilage cells to repair damaged areas. A recent study following patients who underwent MACI in the patellofemoral joint, reported good clinical outcomes at 10 years or more after surgery.
These findings are encouraging, suggesting that with the right surgical approach and rehabilitation, many patients can return to a high level of activity. Cartilage restoration offers a valuable option for those with significant defects who have not responded to conservative treatment.
Book a specialist assessment for your knee pain today
Most cases of kneecap pain improve with physiotherapy, activity modification, and targeted strengthening. However, when symptoms persist or are linked to structural problems such as instability or significant cartilage damage, surgical intervention may be required.
If you’re experiencing ongoing pain around the front of your knee, a specialist assessment with Mr Punwar can help pinpoint the underlying cause and guide the right treatment plan. With the appropriate treatment plan, whether that be surgical or non-surgical, combined with rehabilitation, it is possible to restore function and return to the activities you enjoy.
