Knee Cartilage Injury (Cartistem)

Knee cartilage injury refers to an injury where the cartilage on the joint surface and subchondral bone suffer extensive damage (i.e. partial or complete detachment of the cartilage from the joint surface accompanied by avascular damage).

Symptoms and Diagnosis

Typical symptoms of knee cartilage damage include periarticular pain, intra-articular inflammation, swelling, locking, joint instability, heat, weakening of the femoral muscles, and limited range of motion (ROM). Preliminary diagnosis may be done by an X-ray. This can be followed up by a full diagnosis using Computed Tomography (CT) to further assess the extent of the injury. Also, Magnetic Resonance Imaging (MRI) can be used to diagnose knee cartilage injury in its early stages or evaluate the condition of the joint surface. Arthroscopes can also be used to diagnose the status of the joint surface, check the osteochondral stability of the joint, and carry out minor surgical repairs.

Treatment

Non-surgical treatment

Treatment depends on the severity of the injury. Typically, however, non-surgical treatment may include rest, rehabilitation, physical therapy, injection, and an orthopedic cast. Recently, the more popular trend is to strengthen the muscles surrounding the joint, while working to prevent joint stiffness, muscle atrophy, and degenerative changes in the cartilage.

Surgical treatment

Surgical treatment options include the removal of loose bodies (clean-up), debridement surgery, microfracture surgery, autologous chondrocytes transplantation, and autologous bone marrow stem cell therapy.

Stem Cell Cartistem treatment

Stem cell Cartistem is a medical product, mainly composed of mesenchymal stem cells of the fetus from umbilical cord blood. Stem cell Cartistem is administered to the injured site via surgery or arthroscopy. It treats damaged knee cartilage in patients with osteoarthritis caused by degeneration or repetitive trauma.

Characteristics

  • Cartistem is a tissue-regenerating medical product used to treat damaged cartilage.
  • Cartistem delivers excellent cartilage regeneration benefits with a single procedure.
  • Cartistem delivers tangible cartilage regeneration benefits in older patients (50 or over).
  • Cartistem can regenerate hyaline cartilage (original cartilage cells).

Rehabilitation after surgery

2 weeks after surgery
Patients will be required to secure the knee joint in a fully extended position.
Patients will be prescribed exercises to reduce muscle loss in the quadriceps area.
Week 2 ~ Week 6
Patients will be required to limit the amount of weight applied to the joint. If necessary, patients can use two crutches to walk (only toes will be allowed to touch the ground).
Patients will be prescribed exercises to begin movement of the joint based on accurate diagnoses of the biomechanical characteristics of their knee joint. Exercises will be limited to a tolerable pain level.
Week 6 ~ Week 12
Parents will be required to but their full weight on the joint and regain full FOM of the joint. Depending on the patient's condition, rehabilitation may take up to 12 weeks or longer.
Week 12 ~ Week 24
Patients will be required to slowly increase their exercise intensity to improve their lower body strength and endurance.
Patients will be prescribed agility and plyometric exercises to fully recover their joint.
Patients will be returned to sporting activities when they can perform functional exercises such as plyometrics without difficulty, and score 85% or higher in their isokinetic tests (tendons). Athletes must clear 90% in their isokinetic tests.
