RESUMEN
Objetivo. Valorar la potencia de aparato extensor en la revisión de artroplastia total de rodilla (ATR) entre el abordaje parapatelar medial y el abordaje con osteotomía rotuliana. Material y método. Se realiza un estudio retrospectivo sobre 22 pacientes. El seguimiento medio fue 24,6 meses y edad media 70,2 años. Resultados. Existe un déficit mayor en la potencia extensora con la vía transrotuliana (22,3%) frente a la vía parapatelar medial (12,3%). Con la vía parapatelar aparecieron dos casos de avulsión parcial del tendón rotuliano y un caso de necrosis cutánea. Presentaron molestias femoropatelares 4 pacientes en el abordaje parapatelar medial y 4 casos con la vía transrotuliana. Existió falta de unión de la osteotomía en dos casos y seudoartrosis fibrosa en 3 pacientes. Conclusiones. Existe una disminución de la potencia extensora en el abordaje transrotuliano con menores complicaciones sobre el aparato extensor. Este abordaje podría considerarse en casos especialmente complejos de revisión protésica de rodilla
ABSTRACT
Purpose. To compare the repercussion of total knee arthroplasty (TKR) on knee extensor strength when performed through a medial parapatellar approach vs. a patellar osteotomy. Materials and methods. This is a retrospective study that included 22 patients. Mean follow-up was 24.6 months and mean age 70.2 years. Results. There is a greater deficit in the knee extensor mechanism when the transpatellar approach is performed (22.3%) vs. the medial parapatellar approach (12.3%). With the parapatellar approach, there were two cases of a partial avulsion of the patellar tendon and one case of skin necrosis. Four patients had patellofemoral discomfort with the medial parapatellar approach and another four with the transpatellar one. There were two cases of non-union of the osteotomy and three cases of fibrous pseudoarthrosis. Conclusions. There is a reduction in knee extensor strength with the transpatellar approach with fewer complications for the extensor mechanism. This approach could be considered in specially complex cases of TKR
