ICD-10: M67.51

Plica syndrome, particularly in the context of the right knee, is a condition that arises from irritation or inflammation of the plica, a fold of synovial tissue in the knee joint. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is crucial for accurate diagnosis and effective management.

Clinical Presentation

Plica syndrome typically presents with a combination of symptoms that can vary in intensity. Patients often report a history of knee pain that may be exacerbated by specific activities, particularly those involving repetitive knee motion, such as running or cycling. The pain is usually localized to the medial aspect of the knee, where the plica is situated.

Signs and Symptoms

1. Pain:
   - Patients commonly experience sharp or aching pain in the knee, particularly on the inner side. This pain may worsen with activities that involve bending or straightening the knee, such as squatting or climbing stairs[1].

2. Swelling:
   - Mild swelling may be present, particularly after prolonged activity. This swelling is often due to inflammation of the plica and surrounding tissues[1].

3. Clicking or Popping Sensation:
   - Many patients report a sensation of clicking or popping within the knee joint, especially during movement. This is often attributed to the plica catching on the femoral condyle during knee flexion and extension[1].

4. Limited Range of Motion:
   - Some individuals may experience a reduced range of motion in the knee, particularly if pain is significant or if swelling is present[1].

5. Tenderness:
   - Physical examination often reveals tenderness along the medial aspect of the knee, where the plica is located. This tenderness can be elicited by palpation[1].

Patient Characteristics

Plica syndrome can affect individuals of various ages, but certain characteristics are more commonly observed:

• Age:

• It is frequently seen in younger, active individuals, particularly those involved in sports or activities that place repetitive stress on the knee[1].

• Activity Level:

• Athletes or individuals who engage in high-impact sports are at a higher risk due to the repetitive knee motions involved in these activities[1].

• Gender:

• While plica syndrome can affect both genders, some studies suggest a higher prevalence in males, possibly due to greater participation in sports[1].

• Previous Knee Injuries:

• A history of knee injuries or surgeries may predispose individuals to develop plica syndrome, as previous trauma can lead to changes in knee mechanics and increased stress on the plica[1].

Conclusion

Plica syndrome of the right knee is characterized by specific clinical presentations, including localized pain, swelling, and mechanical symptoms such as clicking. Understanding the signs and symptoms, along with patient characteristics, is essential for healthcare providers to make an accurate diagnosis and develop an appropriate treatment plan. Early intervention can help alleviate symptoms and prevent further complications associated with this condition.
