Impact of knee recurvatum on machine-assessed muscle recovery from isokinetic after anterior cruciate ligament surgery
Résumé
BackgroundRecurvatum is generally considered to be a risk factor for graft tendon failure and a probable risk factor for native anterior cruciate ligament failure.PurposeTo evaluate the impact of recurvatum and the type of anterior cruciate ligament repair on the hamstring/quadriceps ratio 4 months after surgery.Materiels and methodsOne hundred and three patients having undergone anterior cruciate ligament surgery were included between July 1st, 2017, and July 1st, 2018. A clinical check-up and an isokinetic test were performed 4 months after surgery. The hamstring/quadriceps ratio was calculated and then assessed as a function of the type of surgery and the presence or absence of recurvatum.ResultsThe mean hamstring/quadriceps ratio on the operated side did not differ significantly (P = 0.87) when comparing patients with recurvatum (1.2) and those without (also 1.2). The interaction between the type of surgery and recurvatum was statistically significant (P = 0.019). In patients with recurvatum, the mean hamstring/quadriceps ratio was 1.49 in the patellar tendon group and 1.04 in the hamstring ligament group
