Potential causes of knee flexion pain

It is important to note that knee pain is a usual reason why many consult their doctors. The knee is the biggest weight-bearing joint and endures significant strain when an individual runs, walks or play sports. The knee has essential actions such as flexion and extension or bending and straightening. In addition, the knee is also capable of sliding and pivoting slightly. If the individual experiences knee flexion pain or when the knee is bent, it is an indication of injury or damage inside the joint.

Arthritis

Various forms of arthritis can affect the knee joint. Osteoarthritis which is the most prevalent form of arthritis can affect the knee. The other forms that can affect the knee include rheumatoid arthritis, septic arthritis and gout. Those who are diagnosed with arthritis can experience varying degrees of pain while walking or standing along with stiffness, swelling and loss of flexibility. In some cases, there is also knee flexion pain and difficulty.

Patellar tendinitis

Tendinitis involves inflammation or irritation of one or several tendons that support a particular joint. Oftentimes, it is a due to overuse or overtraining. Many athletes are susceptible to develop patellar tendinitis.

The tendon links the quadriceps in the front aspect of the thigh to the inferior leg bone. Cyclists, runners and skiers rely on this movement to properly support their performance, thus putting them at risk for developing the condition. These individuals usually experience knee flexion pain with or without weight bearing.

Bursitis

Bursitis involves inflammation of the small-sized fluid sacs that cushion the exterior of the knee joint. This condition can trigger intense knee flexion pain during weight bearing such as climbing the stairs. Individuals who have bursitis might also experience swelling, redness and fever.

Patellofemoral pain syndrome

Those who have patellofemoral pain syndrome can experience pain around or below the kneecap. In most cases, the pain is worse during flexion or after being seated for extended periods.

Individuals who have this overuse injury should take some time off from activities. The treatment involves the application of an ice pack several times throughout the day and taking into consideration the appropriate footwear being used. There are also exercises that the individual should perform to strengthen the muscles surrounding the kneecap as well as relieve the knee flexion pain.

Baker’s cyst

Baker’s cyst involves the accumulation of fluid in the back part of the knee. This condition can be caused by herniation of the knee joint capsule or tearing of the meniscal cartilage of the knee.

This condition is different from a blood clot which can cause similar knee flexion pain. When it comes to a blood clot, it is considered as a medical emergency that requires immediate attention.

Osgood-Schlatter disease

This condition involves inflammation of the cartilage, bone and tendon at the top part of the shinbone. In most cases, only one knee is affected and active teenagers are prone to develop the condition.

Osgood-Schlatter disease usually develops throughout the period of growth spurt and typically occurs among teenagers who take part in sports that involve running, rotating or jumping actions. The pain can range from minor to intense and can be persistent. In addition, it is often aggravated with activity and flexion of the knee.
