Abstract

After the treatment of patella fractures the only way to evaluate healing at the articular surface before implant removal is through arthroscopy. The purpose of this study was to examine the healing potential of the cartilage. Arthroscopy was performed in 18 patients at the time of implant removal. The mean age of the patients was 42.1 years. The time elapsed from the index surgery to the arthroscopy and implant removal surgery was 12.9 months. During the arthroscopy, we inspected articular step-off, cartilage loss, and joint surface irregularities. Cartilage irregularities were observed in 13 of the 18 patients. Five patients had well-healed cartilage at the patellar surface. Although none of the patients had displacement at final follow-up X-rays, step-off was detected in two patients during arthroscopy. Our observation showed that cartilage lesions did not correlate with clinical and radiological evaluation. Despite good knee scores, we observed surface irregularities, chondral lesions, and fibrillation in most of the cases implicating subsequent patellofemoral arthritis.

Résumé

La seule façon d'évaluer la cicatrisation de la surface articulaire après traitement de la fracture de la rotule est l'arthroscopie. Le propos de cette étude est d'examiner le potentiel de cicatrisation du cartilage. une arthroscopie a été réalisée chez 18 patients après fracture de la rotule au moment de l'ablation de matériel. L'âge moyen de ces patients était de 42,1 ans. Le temps écoulé entre la chirurgie et l'arthroscopie au moment de l'ablation de matériel a été de 12,9 mois. Durant l'arthroscopie, le cartilage a été analysé surtout en terme d'irrégularités et de pertes de substances. des irrégularités cartilagineuses ont été observées chez 13 patients sur 18. 5 patients sur 18 ont un cartilage qui a parfaitement cicatrisé en surface. Cependant, aucun de ces patients n'avait de déplacement. A la fin du suivi radiologique, une marche d'escalier a été observée chez 2 patients sur les 18 ayant bénéficié de l'arthroscopie. nos observations permettent de montrer que la lésion cartilagineuse n'est pas corrélée à la symptomatologie clinique et radiologique. Cependant, des patients ayant un bon score au genou, peuvent présenter des irrégularités de surface cartilagineuse avec lésions chondrales de fibrillation dans la plupart des cas et peuvent à terme évoluer vers une athrose fémoro-patellaire.
