[Surgery of retrospinal disinsertion of the posterior cruciate ligament of the knee (author's transl)].

Thus in all cases of an isolated tear of the posterior cruciate ligament, with an interglenoid fragment, whe fixation by a screw or clip was carried out, we obtained good results by simple surgical treatment. In spite of the small size of this series, the results were in perfect harmony with those of other authors, which justifies surgery. In three other cases of a tear of the posterior cruciate ligament, orthopedic treatment was adopted for various reasons; comparison of the results was definitely in favour of surgery owing to the duration of plaster immobilisation and physiotherapy in the first group and the functional sequelae with chronic invaliding laxity in the cases treated conservatively.
