Shaving or chondrectomy is a procedure where the main focus is the reduction of the inflammation. When performing chondrectomy, the damaged cartilage is removed, and the aim is to level the cartilage surface through a more or less radical operation. Other procedures are included, such as a resection of meniscus, removal of loose bodies and osteophytes, partial synovectomy, lavage, or debridement.
Treatment consists of removing the damaged or undermined cartilage to provide a smooth surface of the cartilage lesion and firm edges facing the surrounding cartilage. The use of saline is 0.5–1 liter during the arthroscopies, but lavage as such is not carried out. Anesthesia used could be local, spinal or general in rare cases. All patients are immediately allowed full weight-bearing and extension-flexion movement of the leg. In severe cases the patients were recommended to avoid rotation of the knee when weight was put on the knee for 6 weeks after the operation.
