- Anterior Cruciate Ligament (ACL) Injury. The primary diagnosis for this ACL injury. ACL injury is a sprain or tear ACL, one of the major ligaments in the knee (Korakakis et al., 2019). The injury occurs mostly in sportspersons. The disease causes pain in the knee. It has been included as the primary diagnosis because the patient is a sportsperson and recently got injured during a game.
- Knee locking: Characteristics of knee locking include catching sensation, swelling of the affected knee, and pain with extension (Lee, Nixion, Chandratreya & Murray, 2017). The disease is not a primary diagnosis because the patient is no swelling in the knee.
- Osteochondritis Dissecans: OCD is a joint condition that occurs when blood is not enough in the end of the bone. It also causes pain in the knee, and that is why it has been included in the diagnosis.
- Juvenile idiopathic arthritis: JIA is the swelling of the joints. The disease occurs before a kid reaches 16 years (Ramanan et al., 2017). It causes joint pain, and that is why it has been included in the diagnosis.
- Repeated kneecap dislocation: Repeated patellar subluxation is the continued instability of the patellar, which causes knee pain.

Osgood-Schlatter disease is a common condition that affects adolescents who are going through growth spurts. It is characterized by pain and swelling at the front of the knee, just below the kneecap, where the patellar tendon attaches to the shinbone (tibia). This area may also feel tender to the touch, and may be accompanied by a visible bump.
The condition is caused by repeated stress on the patellar tendon, which connects the kneecap to the shinbone. During growth spurts, bones and muscles may grow at different rates, which can create tension on the tendon. This tension can cause small injuries to the tendon where it attaches to the shinbone, leading to inflammation and pain.
Osgood-Schlatter disease typically occurs in active adolescents who participate in sports that involve running, jumping, or other high-impact activities. Treatment typically involves rest, ice, and anti-inflammatory medication to reduce pain and swelling. In more severe cases, a knee brace or crutches may be necessary to alleviate pressure on the affected area. In most cases, the condition resolves on its own with time and conservative treatment, although symptoms may persist for several months or even years.
The most common symptoms of Osgood-Schlatter disease include:
- Knee pain: The main symptom of Osgood-Schlatter disease is pain in the knee, especially during activity. The pain is typically located just below the kneecap, at the top of the shinbone.
- Swelling: The affected area may become swollen and tender to the touch.
- Bump: A visible bump may form just below the kneecap, where the patellar tendon attaches to the shinbone.
- Stiffness: The knee may feel stiff or tight, especially after periods of inactivity.
- Limited range of motion: The affected knee may be difficult to fully bend or straighten.
- Worsening symptoms with activity: Symptoms typically worsen with physical activity, especially running, jumping, or other high-impact activities.
If your child is experiencing any of these symptoms, it is important to seek medical attention from a healthcare provider or sports medicine specialist. Early diagnosis and treatment can help prevent the condition from worsening and improve outcomes.
Patellofemoral pain syndrome
Patellofemoral pain syndrome, also known as runner’s knee, is a common condition characterized by pain and discomfort in the front of the knee, specifically around the kneecap (patella) and the groove in the thigh bone (femur) where the patella rests. This pain may be sharp or dull and is often aggravated by activities that involve bending the knee, such as running, jumping, or climbing stairs.
The exact cause of patellofemoral pain syndrome is not well understood, but it is believed to be related to a number of factors, including overuse, muscle imbalances, structural abnormalities, and biomechanical issues. Some common risk factors include:
- Overuse: Participating in activities that involve repetitive knee bending or impact, such as running, jumping, or cycling, can increase the risk of developing patellofemoral pain syndrome.
- Muscle imbalances: Weakness or tightness in certain muscles, such as the quadriceps or hip muscles, can affect the alignment and movement of the patella, leading to pain and discomfort.
- Structural abnormalities: Issues such as flat feet, a high arch, or misaligned leg bones can alter the way weight is distributed through the knee joint and contribute to patellofemoral pain syndrome.
- Biomechanical issues: Poor running or jumping technique, as well as improper footwear, can increase the risk of developing patellofemoral pain syndrome.
Treatment for patellofemoral pain syndrome typically involves a combination of rest, physical therapy, and pain management. Your healthcare provider may recommend exercises to strengthen and stretch the muscles around the knee, as well as modifications to your activity level or technique. Non-steroidal anti-inflammatory drugs (NSAIDs) may be prescribed to manage pain and inflammation. In some cases, bracing or taping may be recommended to help support the knee joint. Surgical intervention is rarely necessary.
What Causes Sudden Knee Pain in Both Knees?
Knee pain is a common issue that many people face at some point in their lives. It can range from mild discomfort to excruciating pain and can affect one or both knees simultaneously. If you’re experiencing sudden knee pain in both knees, it can be concerning and disruptive to your daily life. In this comprehensive guide, we will delve into the various potential causes of sudden knee pain in both knees, helping you understand the possible reasons behind this discomfort.

What is the most common cause of bilateral knee pain?
The most common cause of bilateral knee pain, which means pain in both knees simultaneously, is osteoarthritis. Osteoarthritis is a degenerative joint condition that often affects both knees in individuals, especially as they age. It occurs when the protective cartilage that cushions the ends of the bones in the knee joint gradually wears down over time, leading to pain, stiffness, and reduced mobility.
This condition is more prevalent in older adults, but it can also affect younger individuals, especially if they have a history of knee injuries, genetic predisposition, or certain risk factors like obesity. Osteoarthritis in both knees can cause discomfort during daily activities, such as walking, climbing stairs, and standing for extended periods.
While osteoarthritis is the most common cause of bilateral knee pain, other factors like overuse, ligament injuries, and medical conditions can also contribute to knee pain in both knees. It is essential to consult a healthcare professional for a proper diagnosis and appropriate treatment if you are experiencing persistent bilateral knee pain.
What are the symptoms of bilateral knee osteoarthritis?
Bilateral knee osteoarthritis refers to the presence of osteoarthritis in both knees simultaneously. Osteoarthritis is a degenerative joint condition that can cause a range of symptoms in the knees. Here are the common symptoms associated with bilateral knee osteoarthritis:
- Pain: Pain in both knees is a hallmark symptom of knee osteoarthritis. The pain may be described as aching, throbbing, or sharp and is often worse after periods of inactivity or excessive use of the knees.
- Stiffness: Individuals with bilateral knee osteoarthritis often experience stiffness in the knees, especially in the morning or after prolonged periods of rest. This stiffness can make it challenging to move the knees freely.
- Swelling: Swelling or inflammation in both knees can occur with osteoarthritis. The knees may appear puffy, and this swelling is typically due to the body’s response to joint irritation.
- Reduced Range of Motion: Bilateral knee osteoarthritis can lead to a decreased range of motion in both knees. This limitation may make it difficult to fully bend or straighten the knees.
- Crepitus: Crepitus refers to a crackling or grating sensation or sound when moving the knees. It can be felt or heard when bending or extending the knees and is caused by roughened or damaged cartilage surfaces rubbing against each other.
- Instability: Some individuals with bilateral knee osteoarthritis may experience a sense of knee instability, which can lead to a feeling of unsteadiness while walking or standing.
- Weakness: Muscular weakness in the thighs and around the knee joint can develop due to the pain and reduced activity associated with osteoarthritis.
- Pain with Activity: Knee pain tends to worsen with weight-bearing activities such as walking, climbing stairs, or standing for prolonged periods.
- Pain at Rest: In advanced cases, knee pain may persist even at rest or during nighttime, disrupting sleep patterns.
- Difficulty with Daily Activities: As bilateral knee osteoarthritis progresses, it can interfere with routine activities like getting up from a chair, bending down, or participating in recreational activities.
- Bony Enlargements: Over time, the development of bony enlargements, called bone spurs or osteophytes, can be observed around the knee joint. These bony growths can contribute to joint pain and decreased mobility.

What is the cause of patellofemoral pain syndrome?
Patellofemoral Pain Syndrome (PFPS) is a common knee condition characterized by pain and discomfort around the front of the knee, specifically where the kneecap (patella) meets the thigh bone (femur). The exact cause of PFPS can vary from person to person, and it often results from a combination of factors.
Here are some of the primary factors that contribute to the development of PFPS:
- Muscular Imbalances: One of the leading causes of PFPS is muscular imbalances around the knee joint. Weakness or tightness in the muscles that support the patella, such as the quadriceps and hamstrings, can lead to abnormal tracking of the kneecap, causing pain and irritation.
- Overuse or Excessive Stress: Activities that involve repetitive knee motion, such as running, jumping, or squatting, can put excessive stress on the patellofemoral joint. This overuse can lead to irritation of the joint and the development of PFPS, especially if proper rest and recovery are not observed.
- Malalignment of the Patella: Sometimes, the patella may not track properly within its groove in the femur. This misalignment can result from structural issues or muscle imbalances and may contribute to PFPS.
- Trauma or Injury: A direct blow to the kneecap or a fall can result in PFPS. Such incidents can cause damage to the cartilage under the patella, leading to pain and inflammation.
- Improper Footwear or Biomechanics: Wearing shoes that do not provide adequate support or having abnormal lower limb biomechanics, such as flat feet or excessive pronation, can increase the risk of PFPS by altering the way forces are distributed through the knee joint.
- Muscle Tightness: Tightness in the muscles and connective tissues around the knee, such as the iliotibial band (IT band) or the calf muscles, can contribute to PFPS by affecting joint mechanics and causing discomfort.
- Excessive Weight: Carrying excess body weight can increase the load on the knee joint, potentially leading to PFPS or exacerbating existing symptoms.
- Gender and Age: PFPS is more common in females, particularly adolescents and young adults. Hormonal factors and differences in hip and thigh anatomy may play a role.
- Training Errors: Inadequate warm-up, poor training techniques, sudden increases in intensity or duration of exercise, or improper biomechanics during physical activities can all contribute to the development of PFPS.
