              Application No. 09/523,503                                                                                 



                     Figure 8 of Whiteside is a side view of a femoral surface modifying instrument in                   
              the nature of a distal femoral condyle cutting guide 80 having a guideplate 82 having a                    
              cutting guide surface 83 held transverse to the central long axis of handle 36 and                         
              attached to main body 81 by means of arm 84.  Main body 81 contains central passage                        
              85 adapted to cooperatively receive the guide handle 36 (not shown) of intramedullary                      
              alignment guide 30 and threaded passage 86 adapted to receive locking bolt 88 to                           
              fixedly secure guide handle 36 to the main body 81 in proper alignment with guide 30.                      
              Figure 9 of Whiteside shows the cutting guide 80 with guide handle 36 in place and with                    
              locking bolt 88 in position to secure main body 81 to guide handle 36.  Cutting guide 80                   
              is likewise designed to modify the distal femoral condyles to suit a preselected distal                    
              femoral prosthesis.                                                                                        


                     Whiteside's distal femoral condyle cutting guide 80 is placed on guide handle 36                    
              and moved forward (see Figure 19) until the cutting guide surface 83 (not shown) is                        
              positioned to remove the desired amount of bone (approximately the thickness of the                        
              distal portion of the femoral prosthesis component).  Cutting guide 80 is then secured to                  
              handle 36 by means of locking bolt 88.  A saw blade 190 having saw teeth 192 is then                       
              placed against cutting guide surface 83 (not shown) on the femoral side of guideplate                      
              82 and a rough cut of each of the two distal femoral condyles is made, one cut on each                     
              femoral side of guideplate 82.  Cutting guide 80 is then removed and the rough cut is
