[Patelloplasty for extensive lesions of the patellar cartilage].

We have been able to review 100 cases of patelloplasty for extensive lesion of the patellar cartilage with an average follow up of 5 years. The technic for the procedure is described. The study of the results (64% of good and very good results) allow us the emphasize the criteria for best indications and technic.

[Reconstruction of loss of bony substance in limbs by free vascularized fibula transplant].

The authors present their experience of bone-loss reconstruction by a free vasculized fibular transfer. 62 cases were operated, with an average follow-up of 6 years (between 24 to 13 years). Studied were 15 upper limbs (10 humerus, 3 ulna, 2 radius), 28 femurs and 19 tibias.

[Late results of Mac Murray's osteotomy].

From a total of 817 cases, 133 cases were reviewed where a Mc Murray osteotomy had been carried out more than 10 years previously. Operative results were favourable, but the authors stress the very precise indications for this procedure. Deterioration occurred in one case where the indication appeared dubious.

[Stiffness of the knee of joint origin].

The knee usually loses its mobility following trauma, such as fracture of the femur, fracture of the upper extremity of the tibia, or fracture of the patella. We are concerned here only with joint stiffness, exclusive of any case presenting limited mobility of the knee articulation associated with retraction and/or adhesions of the entire quadriceps muscle of the femur. Forceful mobilization is strongly discouraged.
