Meniscus & Cartilage Repair
Whether you damage the meniscus or articular cartilage in your knee, chances are you need a minimally invasive procedure to repair the tissues. As a specialist in arthroscopic knee surgery, Paul Codjoe, MD, has extensive experience performing several procedures for meniscus and cartilage repair that promote healing, ease your pain, and improve knee function. To learn more, call the New Jersey office nearest you in Hamilton, Princeton, or Lawrenceville, or contact the office in Langhorne, Pennsylvania. You can also book an appointment online.
Meniscus & Cartilage Repair Q & A
What is the meniscus?
The meniscus is a layer of cartilage sandwiched between the leg bones in your knee. You have two C-shaped menisci, one on the inner part of the knee and the other on the outer side.
The menisci cushion the bones, stabilize the knee joint, and absorb shock. Most importantly, they spread out the intense pressure placed on the knee joint when you walk, run, and jump. Spreading out the force on the joint protects the articular cartilage that covers the ends of the two leg bones.
How is the meniscus damaged?
Meniscus tears most often occur when you forcefully twist your knee or suddenly stop running. The cartilage also slowly degenerates as you get older. As a result, older adults can easily tear the menisci with a minor injury or normal movement like squatting.
What challenges affect meniscus and cartilage repair?
Articular cartilage seldom repairs itself because it doesn’t have a direct blood supply. Instead, it depends on getting nourishment from the underlying bone.
Even if it gets enough blood to heal, the new cartilage that grows in is dense fibrocartilage, which doesn’t provide the same protection as the original articular cartilage.
The outer thirds of each meniscus, called the red zone, has a good blood supply and often heals with non-surgical care. But the inner two-thirds, the white zone, lack a blood supply. Without blood, that part of the meniscus can’t heal.
How do orthopedic surgeons perform a meniscus repair?
Dr. Codjoe repairs the meniscus and articular cartilage using minimally invasive arthroscopic surgery. He specializes in several procedures to repair the meniscus, including:
Partial meniscectomy
Dr. Codjoe removes the damaged part of the meniscus, and then eliminates frayed or damaged edges to create a smooth surface.
Meniscus repair
Whenever possible, Dr. Codjoe repairs the tear rather than removing any of the meniscus. He uses stitches or suture anchors to bring the torn pieces together.
Meniscal transplant surgery
In severe injuries, Dr. Codjoe removes the entire meniscus. If you’re under 40 years old and your articular cartilage is in good shape, you may be a good candidate for a meniscus transplant. Dr. Codjoe replaces the damaged meniscus with cartilage from a donor bank.
How do orthopedic surgeons perform cartilage repair?
Dr. Codjoe has several choices of procedures for repairing damaged articular cartilage, including:
Restorative surgery
If you get restorative surgery, Dr. Codjoe places tissues in the damaged areas that promote the growth of new articular cartilage.
Microfracture
Dr. Codjoe uses a special tool to make holes in the bone under the cartilage. That activates the healing response, promotes a fresh blood supply, and encourages new fibrocartilage growth to repair the cartilage.
Abrasion arthroplasty
During abrasion arthroplasty, Dr. Codjoe uses a burr to scrape the surface of the bone under the articular cartilage. Like a microfracture, that activates healing and produces new fibrocartilage.
Arthroscopic debridement
Using arthroscopic surgery, Dr. Codjoe trims away rough edges in the cartilage and removes loose fragments.
