The unstable patella in children.

The authors reviewed 102 unstable patellas which had been observed and treated from 1964 to 1990. They were divided according to whether they suffered from traumatic dislocations, recurrent dislocations or malformative instability. The clinical findings were the major stage of the check up. In the field of imaging, standard X-rays had to be performed in all cases. MRI was of interest in the congenital dislocations, in order to thoroughly investigate the soft tissue anomalies. Two types were described: Type 1 was observed in children with joint laxity, but without major X-ray anomalies; Type 2, a major femoropatellar dysplasia could be formed with some bone deformity. The latter was observed in the malformative instability. Four different surgical procedures have been used, from the release of the retinacula of patella to the medial displacement of the patellar tendon or the tibial tuberosity. This study emphasises the concept of a true development dysplasia of patella (DDP) which can gather the different varieties of the instability of patella.

Classification of clubfoot.

Clubfeet must be classified according to severity to obtain reference points, assess the efficacy of orthopaedic treatment, and analyze the operative results objectively. A scale of 0-20 was established on the basis of four essential parameters: equinus in the sagittal plane, varus deviation in the frontal plane and derotation around the talus of the calcaneo-forefoot (CFF) block and adduction of forefoot on hindfoot in the horizontal plane. Four grades of clubfeet can be individualized: (a) Benign feet so-called "soft-soft feet," grade I, similar to postural feet, with a score of 5 to 1 (these mild feet must be excluded from any statistics as they tend to increase good results); (b) moderate feet, so-called "soft > stiff feet," grade II (reducible but partly resistant, with a score of 5-10); (c) severe feet, so-called "stiff > soft feet," grade III (resistant but partly reducible, with a score of 10-15); and (d) very severe, pseudoarthrogryposic feet, so-called "stiff-stiff feet," grade IV (score of 15-20 points). To avoid risks of errors, our method is based on a very complete checklist and on diagrams. Our training material inculdes an audiovisual package.

Final evaluation of clubfoot.

After analyzing the multiple evaluations described in the literature, we propose an evaluation that can be used during growth. The global score is based on 50 points. The normal foot is scored 0. The functional evaluation (passive motion, muscle function, and gait analysis) is based on 28 points. The morphology is based on 12 points. The radiographic analysis is scored on 10 points. The final evaluation score is linked to the initial classification at birth. The gain during the treatment is the difference between the score at birth and the score of the final evaluation. It is noted as a percentage.

[Patellar instability in children].

Current work on disease states involving the patella has led to increased interest in patellar instability. We reviewed a series of patellar luxations. True trauma-induced luxations are rare. Most cases are recurrent luxations in subjects with a morphological anomaly of the knee extensor system. Because of the growth cartilages, selective therapeutic techniques are needed to stabilize the patella. Recurrent or permanent luxations of the patella result from congenital malformations of the muscles or skeleton. A complete MRI study is highly indicated. The patella can be correctly realigned by surgical release. In cases with femoropatellar dysplasia, which is not specific for children, well conducted rehabilitation therapy often leads to favourable outcome.
