A techinque for recording the results of knee surgery.

A research form for recording clinical data relating to the arthritic knee is described. Data are recorded using a numerical code which facilitates transfer to a computer and provides an easily read record. Any form must be a compromise but the one described has been proven clinically by providing the data for a multi-center evaluation of hundreds of knees observed over a period of 5 years. A shorter form is described for routine follow-up purposes.
