Meniscus Tear is a common type of Knee Injury, which people encounters very often. Meniscal tear is one of the most frequently occurring cartilage injuries of the knee. The Meniscus is both the shock absorber of the Knee Joint and the spacer that protects the cartilage which cover top of the femur and tibia bone. It does this by distributing the force equally across the joint. The meniscus is made of living fibrocartilage tissues. Each Knee has two meniscus, a medial and a lateral menisci.
Our Expert Orthopedic Consultant Dr. A K M Mohiuddin has described what is Meniscus Tear, what are the symptoms, why it occurs and its treatment.
What causes Meniscus Tear?
There can be a number of causes which can result in Meniscus Tear, the most common causes are :
- Impact on the side or front of the knee
- Over rotation of the knee due to planting or cutting
- Rapid stepping or squatting on an uneven surface
- Unexpected, quick force on knee
- Degenerative conditions, such as knee osteoarthritis, can also cause this tear.
What Does a Meniscus Tear Feel Like?
This condition is just like any other knee injury, but the impact can vary person to person. Symptoms of a meniscus tear include:
- Pain in the knee
- A popping sensation during the injury
- Difficulty bending and straightening the leg
- A tendency for your knee to get “stuck” or lock up
At first, the pain may not be bad. You might even play through the injury. But once the inflammation sets in, your knee will probably hurt quite a bit.
Type of meniscus Injury:
There are various type of tear. In the image shown below, we can get a clear idea on the types of Meniscus Injury
Why not fix Meniscus Surgically:
More than 90% of the meniscus surgery does not “repair” the meniscus but rather removes the torn piece. Given its shock absorbing function, less shock absorber means more shock gets delivered to the cartilage and bone. Removing of meniscal tissue in surgery cause advanced Osteoarthritis.
Doctor’s at the Hospital of Special Surgery, USA in their new paper found that meniscus tissue removal not only impact the knee at the point of the surgery but throws the whole Knee out of balance and leads to several points of Cartilage deterioration.
Partial meniscectomy and shaving is a
- Controversial treatment option for degenerative meniscal tears.
- Is strongly associated with incidence osteoarthritis within 1 year.
- Is associated with increased risk of worsening cartilage damage.
Why PRP & Stemcell therapy in treating Meniscus Tear?
- PRP and Stemcell therapy become the new clinical strategy for the treatment for meniscus tear.
- PRP released growth factors which will stimulate healing of meniscus tear. The growth factors in the PRP cause a proliferation and regeneration of injured tissue. , This boosts fibroblastic events involved in tissues healing causing these tears to heal.
- Platelet Rich Plasma therapy effective in internal displacements of Knee including meniscus tear.
- Stem Cell therapy regrows meniscus tissue.
Stemcell and PRP therapy to be significant potential for biological augmentation and tissue engineering strategies in meniscus repair.
