When the patient undergoes cartilage surgery of the knee, hip, ankle, or shoulder, for example, by whatever method, they should be aware that they need a long recovery period. It is therefore very important that the patient is committed to the whole process. However, it should also be borne in mind the timeframe of one year for recovery is an example of the amount of time required compared to the hours of the surgery. The actual timeframe required depends on a large number of factors. The second important point is that rehabilitation is a progressive activity. In this context, ‘progression’ means safely increasing workloads and stimuli on the repaired joint during the recovery process. The third point is that the tissues need to be stimulated, as they cannot recover by themselves.
