[Patella infera. Apropos of 128 cases].

A low patella is frequently a complication of a lesion of the knee but it can also present secondary symptoms of its own. The authors describe an original method for assessment of the vertical level of the patella. They have tried to establish a relationship between the low situation of the patella and pain of a certain type associated with limited flexion of the knee. Physiopathological and biomechanical evidence is taken into account. In most instances, a low patella is secondary either to a mechanical cause, natural or iatrogenic, or to an inflammatory cause such as algodystrophia. 29 patients out of 128 observed cases have been operated on. 17 of these were due to excessive transplantation of the anterior tibial tubercle. In most of the cases the tibial tubercle was transplanted upwards in association with a joint release. In only 3 cases a patellectomy was done. The results were excellent or good in half of the cases and unsatisfactory in the other half.

[The treatment of genu recurvatum (author's transl)].

50 cases of genu recurvatum were classified into three types: osseous (malunion, epiphysiodesis), capsular and ligamentous (congenital hyper-extension, sequelae of old ligament rupture) and combination of the two types. The author's have analysed the results of 44 surgical procedures. The main procedure practised has been an opening wedge osteotomy of the upper end of the tibia above the level of the tibial tubercle with a graft to fill the gap. It is important to avoid distal displacement of the patella by detachment of the tibial tubercle and reattachment more proximally at the end of the surgical procedure. Osteotomy is always indicated but should be combined with a capsular repair or combined types. The results are satisfactory especially in cases due to premature closure of the growth plate.
