Roturas totais do aparelho extensor do joelho

Abstract

ResumoObjetivoEstudo retrospectivo sobre roturas totais do aparelho extensor do joelho que compara as fraturas da patela com as roturas tendinosas.MétodosAmostra com 190 pacientes e 198 roturas totais do aparelho extensor do joelho. O tempo mínimo de seguimento após a cirurgia foi de um ano e todos os pacientes foram avaliados clínica e radiologicamente pelo mesmo médico.ResultadosAs roturas tendinosas ocorrem mais frequentemente em homens, em pacientes mais novos e estão associadas a níveis clínico‐funcionais superiores em relação às fraturas da patela. No entanto, com atrofia da coxa mais frequente. As fraturas patelares ocorrem mais frequentemente em mulheres com idade mais avançada e provocam mais frequentemente dor residual, déficit de força muscular e limitação das atividades da vida diária. A maior cominuição das fraturas da patela esteve associada a resultados clínico‐funcionais mais desfavoráveis, a níveis mais elevados de dor residual e de desmontagem do material de osteossíntese. A extração precoce do material de osteossíntese esteve associada a melhores resultados. No grupo das roturas tendinosas, mais de metade apresentava doenças consideradas de risco para degeneração tendinosa e um tempo de espera mais prolongado até a cirurgia demonstrou valores de escore de Kujala significativamente inferiores.ConclusãoO tratamento cirúrgico das roturas totais do aparelho extensor do joelho garante bons resultados funcionais, que são superiores para as roturas tendinosas em comparação com as fraturas da patela. No entanto, estão associadas a níveis importantes de dor residual, fraqueza muscular, atrofia muscular e outras complicações.AbstractObjectiveThis was a retrospective case‐control study on total ruptures of the extensor apparatus of the knee, aimed to compare patella fractures with tendinous ruptures.MethodsThe sample included 190 patients and 198 total ruptures of the knee extensor apparatus. All patients were evaluated by the same examiner after a minimum one‐year follow‐up.ResultsTendinous ruptures occurred most frequently in men, in younger patients, and had better clinical and functional outcomes when compared with patella fractures; however, the former presented higher levels of thigh atrophy. Patella fractures occurred most frequently in women and in older patients and caused most frequently caused residual pain, muscle weakness, and limitations in daily activities. Comminuted fractures were related to high‐energy trauma, lower clinical and functional outcomes, and higher levels of residual pain and osteosynthesis failure. Early removal of osteosynthesis material was related to better outcomes. Regarding the tendinous ruptures, over half of the patients presented risk conditions for tendinous degeneration; a longer delay until surgery was related to lower Kujala scores.ConclusionThe surgical repair of bilateral ruptures of the knee extensor apparatus resulted in satisfactory clinical and functional outcomes, which were better for tendinous ruptures when compared with patella fractures. However, these lesions are associated with non‐negligible levels of residual pain, muscle weakness, atrophy, and other complications.
