Isokinetic and neuromuscular testing of the knee, return-to-sport following reconstruction of the anterior cruciate ligament. Prospective study in a cohort of 234 athletes - 15/07/18
Résumé |
Introduction/Background |
After an anterior cruciate ligament (ACL) reconstruction, a complete functional recovery of the knee is required before returning to sport. According to the latest recommendations, a deficit<10% on isokinetic and functional tests of the operated side versus the healthy side means a satisfactory functional recovery. The main objective was to assess the objective postoperative functional recovery of the knee in a large cohort.
Material and method |
A prospective study has included a series of athletes operated in 2013–2016 for a primary total isolated ACL tear, with healthy contralateral knee and having complete postoperative evaluation. Isokinetic tests measured the strength of the quadriceps and hamstrings. Functional tests consisted of hop tests. The primary judgement criterion was postoperative functional recovery (yes/no) defined by a differential<10% on the strength measurement of quadriceps in concentric at 60°/s (Q60°/s) and on single-leg hop test for distance (SLH), at a minimum of 4-months postoperative follow-up.
Results |
One hundred and seventy-three men and 61 women were included, mean age 28.4±8.6 years. At 6.5±1.7 (4–12) months mean follow-up, 44 (18.5%) had satisfactory functional recovery of the knee whose 52 (21.8%) at Q60°/s and 125 (54.3%) at SS. There was no significant difference in the return-to-sport depending on the level of functional recovery. During follow-up, 2 patients showed transplant rupture and 2 controlateral ACL rupture, all classified with insufficient functional recovery.
Conclusion |
At 6-months mean follow-up after ACL reconstruction, the objective functional recovery of the knee is mostly unsatisfactory and appears to be a risk factor for further rupture.
