Patellofemoral osteoarthritis (PFOA) is a specific type of osteoarthritis that affects the patellofemoral joint, which is the area where the kneecap (patella) meets the thigh bone (femur).
Here’s an overview of the symptoms, causes, diagnosis, and treatment of patellofemoral osteoarthritis:
1. Knee pain: Pain in the front of the knee, especially around or behind the kneecap, is the hallmark symptom of PFOA. The pain may worsen with activities like walking, climbing stairs, or kneeling.
2. Stiffness: The knee may feel stiff, particularly after periods of rest or inactivity.
3. Swelling: Some individuals with PFOA may experience mild to moderate knee swelling due to inflammation in the joint.
4. Crepitus: A crunching or grinding sensation may be felt when moving the knee joint.
5. Decreased range of motion: As the condition progresses, the knee’s range of motion may become limited.
6. Weakness and instability: Weakness in the quadriceps and other muscles around the knee may contribute to a sense of instability.
The exact cause of patellofemoral osteoarthritis is not always clear, but several factors can contribute to its development:
1. Age: Osteoarthritis is more common in older adults, and as people age, the cartilage in the knee joint can naturally wear down.
2. Previous knee injuries: A history of knee injuries, such as fractures or dislocations, can increase the risk of developing PFOA.
3. Overuse and repetitive strain: Activities that put excessive stress on the knee joint, such as sports or jobs involving frequent kneeling or squatting, can accelerate cartilage breakdown.
4. Malalignment: Abnormal alignment of the patella and femur can lead to uneven distribution of forces in the knee, contributing to cartilage wear.
5. Genetics: Some people may be genetically predisposed to develop osteoarthritis.
6. Obesity: Excess body weight can place additional pressure on the knee joint, leading to faster cartilage degeneration.
Diagnosing patellofemoral osteoarthritis typically involves a combination of the following:
1. Medical history: The doctor will inquire about symptoms, past injuries, and risk factors.
2. Physical examination: The knee will be examined for signs of tenderness, swelling, crepitus, and range of motion.
3. Imaging tests: X-rays are usually the first imaging test used to visualize changes in the knee joint, such as joint space narrowing, osteophyte formation (bone spurs), and cartilage loss.
4. MRI: Magnetic resonance imaging may be ordered to provide more detailed information about the extent of cartilage damage and soft tissue structures.
The treatment of patellofemoral osteoarthritis aims to relieve pain, improve joint function, and maintain an active lifestyle. Common treatment options include:
1. Pain management: Over-the-counter pain relievers (e.g., acetaminophen, NSAIDs) may be used to manage pain and inflammation.
2. Physical therapy: A physical therapist can design an exercise program to strengthen the muscles around the knee, improve joint stability, and enhance flexibility.
3. Weight management: For individuals who are overweight or obese, weight loss can reduce stress on the knee joint and slow down cartilage degeneration.
4. Assistive devices: The use of knee braces or orthotics can provide support and improve joint alignment during movement.
5. Injections: Corticosteroid injections into the knee joint can help reduce inflammation and alleviate pain, although they are typically used on a short-term basis.
6. Hyaluronic acid injections: These injections aim to lubricate the joint and reduce friction, providing relief from pain.
7. Surgical options: In severe cases where conservative treatments are not effective, surgical procedures like arthroscopy or joint replacement may be considered.
It’s essential for individuals experiencing symptoms of patellofemoral osteoarthritis to seek medical evaluation and treatment. Early intervention can help manage the condition effectively and improve overall knee function and quality of life.

Relieve your tibiofemoral and patellofemoral OA pain by choosing the BioSkin OA Spiral Knee Brace. It provides relief from both forms of OA pain and is easy to fit, apply and use.
The Bio Skin Q Lok will help to reduce the effects of and support the rehabilitation of patellofemoral pain. Using a superior compression and strapping system, the Q Lok pushes the patella back into its correct position in the knee’s trochlear notch, which decreases pain and wear on the joint.
The Bio Skin Q Lok Front Closure helps to reduce the effects of patellar tracking problems and patellofemoral pain due to improper tracking between the patella (knee-cap) and the femur. It uses high levels of compression and a unique strapping system to push the patella back into its correct position in the trochlear notch.
The Bio Skin Q Lok ROM supports rehabilitation of the patellofemoral joint while helping to prevent subluxation and further dislocation during normal activities. A specially designed dynamic patella traction strap make this brace an ideal choice for patients suffering from a high Q angle or from chronic pain from patella tilt, glide and malignment. In addition, its thin, ½ inch range-of-motion hinge allows you to progressively adjust the degree of flexion and extension of the knee.
