Spheroids of human autologous matrix-associated chondrocytes, sold under the brand name Spherox, is a medication used to repair defects to the cartilage in the knee in adults who are experiencing knee pain and problems moving the knee.[1] It is used where the affected area is no larger than 10 cm2 (1.6 sq in).[1]
The most common side effects include arthralgia and joint effusion, which can cause swelling of the joint.[1]
Spherox contains spheroids (spherical aggregates) of chondrocytes, cells found in healthy cartilage, that have been prepared from the patient's own tissues.[1]
Medical uses
[edit]Spherox is indicated for the repair of symptomatic articular cartilage defects of the femoral condyle and the patella of the knee (International Cartilage Repair Society [ICRS] grade III or IV) with defect sizes up to 10 cm2 (1.6 sq in) in adults.[1][2]
To prepare the medicine, a small sample is taken by arthroscopy from the patient's cartilage in the knee.[1] The cartilage cells are then grown in the laboratory to prepare a suspension of chondrocyte spheroids.[1] During arthroscopy, the medicine is placed into the damaged area of the patient's cartilage.[1] The chondrocyte spheroids attach to the cartilage within 20 minutes.[1] People treated with Spherox should follow a specific rehabilitation program including physiotherapy.[1] This allows the chondrocyte spheroids to fill in the cartilage defect.[1]
History
[edit]Spherox has been shown to improve symptoms and knee function in two studies in adults between 18 and 50 years of age.[1] The main measure of effectiveness was the KOOS , which is graded on a scale of 0 to 100 (where 0 means severest symptoms and 100 means no symptoms).[1] The KOOS was self-measured by participants rating the severity of their symptoms such as pain, impact on daily living, sport and recreational activities, and quality of life.[1]
