Unilateral knee pain or discomfort after injury – may indicate a tear
Radial tears of the meniscus refer to tears of the meniscus that begin or occur primarily in the posterior central region of the meniscus, extending outward towards the periphery of the meniscus. This type of tear is caused by a combination of factors, such as traumatic injury, overuse, age, and genetics.
Symptoms include:
- Anterior knee pain
- Swelling or effusion in the knee
- Increased locking and clicking of the knee
- Clicking and popping sensations during movement
- Stiffness and limited motion
Diagnosis and Assessment
Diagnosis of a radial tear in the meniscus typically involves a thorough physical examination and imaging tests. A diagnostic arthroscopy may be recommended to visualize and assess the damage caused by the tear. This can be done using an arthroscope, a small incision used to aid in the direct visualization of the joint.
Treatment
Treatment for radial tears in the meniscus can vary depending on factors such as the extent of the tear, age of the patient, and overall health. Treatment options may include:
- Conservative management with pain and anti-inflammatory medication
- Rest and physical therapy to strengthen the legs and improve alignment
- Arthroscopic repair of the meniscus tear
- Partial meniscectomy to remove damaged tissue
- Total meniscectomy to remove the entire meniscus
Postoperative Care
After surgery, patients are provided with a detailed postoperative care plan designed to promote healing and restore functionality to the knee joint. This can include the following:
- Immobilization using a knee brace and crutches
- Follow-up appointments for physical therapy
- Weight limitations and pain control medication
Complications
Arthroscopic repairs of the meniscus tear have a high success rate, with healing rates reported up to 90% or more. However, complications can arise, including:
- Failure to heal due to insufficient blood supply
- Recurrence of tear after repair
- Infection
- Adverse reactions to medications
Conclusion
Radial tears in the meniscus are a common knee injury that can be managed conservatively or with surgical intervention. By seeking timely diagnosis and treatment, patients can often regain mobility and enjoy a normal active lifestyle once again. It is important to consult with a sports medicine specialist for appropriate evaluation and treatment to avoid further damage and complications.
