ICD-10: M67.50

Plica syndrome, classified under ICD-10 code M67.50, refers to a condition affecting the knee joint, specifically involving the plica, which is a fold of synovial membrane. This condition can lead to pain and discomfort in the knee, particularly during activities that involve bending or straightening the leg.

Clinical Description of Plica Syndrome

Definition and Anatomy

Plica syndrome occurs when the plica, a remnant of embryonic development, becomes irritated or inflamed. The knee joint has several plicae, with the medial plica being the most commonly implicated in plica syndrome. These folds can become thickened or fibrotic due to repetitive trauma or overuse, leading to symptoms that mimic other knee pathologies, such as meniscal tears or patellofemoral pain syndrome[1].

Symptoms

Patients with plica syndrome typically present with:
- Knee Pain: Often localized to the medial aspect of the knee, which may worsen with activity.
- Swelling: Mild swelling may occur due to inflammation.
- Clicking or Popping Sensation: Patients may report a sensation of catching or popping during knee movement.
- Limited Range of Motion: Pain may restrict the ability to fully extend or flex the knee.

Diagnosis

Diagnosis of plica syndrome is primarily clinical, based on the patient's history and physical examination. Key diagnostic steps include:
- Physical Examination: Assessing for tenderness along the medial aspect of the knee and checking for crepitus during movement.
- Imaging Studies: While X-rays may be used to rule out other conditions, MRI can help visualize the plica and assess for associated injuries, although it is not always definitive for plica syndrome[2].

Treatment

Management of plica syndrome typically involves:
- Conservative Measures: Rest, ice, and anti-inflammatory medications are first-line treatments. Physical therapy may also be beneficial to strengthen surrounding muscles and improve knee mechanics.
- Injections: Corticosteroid injections can provide relief in cases of significant inflammation.
- Surgical Intervention: If conservative treatments fail, arthroscopic surgery may be considered to remove the inflamed plica[3].

Conclusion

ICD-10 code M67.50 is designated for plica syndrome of the knee when the specific type of plica is not identified. Understanding the clinical presentation, diagnostic approach, and treatment options is crucial for effective management of this condition. Proper identification and treatment can significantly improve patient outcomes and alleviate symptoms associated with plica syndrome.

   - Patients often experience localized pain around the knee, particularly on the medial (inner) side. The pain may be sharp or aching and can worsen with activities such as squatting, climbing stairs, or prolonged sitting[1].

2. Swelling:
   - Mild swelling may be present due to inflammation of the plica or associated structures in the knee[1].

3. Clicking or Popping Sensation:
   - Patients may describe a sensation of clicking or popping in the knee during movement, which is often due to the plica catching on the femur or other structures[1].

4. Limited Range of Motion:
   - There may be a noticeable decrease in the range of motion, particularly in flexion and extension, due to pain or mechanical blockage[1].

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

Patient Characteristics

Plica syndrome can affect a wide range of individuals, but certain characteristics are more commonly associated with this condition:

• Age:

• It is often seen in younger, active individuals, particularly those aged 20 to 40 years, who engage in sports or activities that put repetitive stress on the knee[1].

• Activity Level:

• Athletes, especially those involved in sports that require frequent knee bending (e.g., running, cycling, or jumping), are at higher risk for developing plica syndrome[1].

• Gender:

• There may be a slight male predominance in cases of plica syndrome, although it can occur in both genders[1].

• History of Knee Injury:

• A history of previous knee injuries or surgeries may predispose individuals to develop plica syndrome, as these factors can alter the normal biomechanics of the knee[1].

Conclusion

Plica syndrome (ICD-10 code M67.50) is characterized by knee pain, swelling, and mechanical symptoms such as clicking or popping. It predominantly affects younger, active individuals, particularly athletes.
