Single-leg assessment of postural stability and knee functional outcome two years after anterior cruciate ligament reconstruction

Abstract

After ACLR (mean time postoperatively: 24+/-1 months), single-leg hop for distance score was normal, when compared with the contralateral limb. Our results indicate that 2 years after surgery, single-limb postural stability in the ACLR group differed significantly from that in the control group. The persistence of poor stability control may be correlated to an impairment in proprioception.

Static and dynamic postural control in competitive athletes after anterior cruciate ligament reconstruction and controls

“…The same pattern of findings was obtained in other studies with different samples and different postsurgery intervals, such as the studies of Bonfim et al [10], Ben Moussa et al [5], and Dauty et al [12], which showed that ACL-reconstructed subjects had greater displacement, velocity, area and total distance in the ACL-reconstructed lower limb in comparison with the contralateral limb and matched limb of controls. We found similar differences in the athletes.…”

Lower Limb Kinematics and Dynamic Postural Stability in Anterior Cruciate Ligament-Reconstructed Female Athletes

“…Our results support our original hypothesis that ACL-R female athletes would demonstrate decreased postural stability on specific directional components of the SEBT when compared with an age-, sex-, and activity-matched uninjured control group and are in agreement with previous findings that competitive athletes who have returned to full sport participation after ACL reconstruction still exhibit postural-control deficits. 50,51 In the present study, ACL-R participants' reach distances on the posterior-medial and posterior-lateral directions of the SEBT were decreased. These observations are in agreement with those of Herrington et al, 23 who reported similar deficits in reach distances in ACL-deficient athletes.…”

“…Further, the hop may not discriminate at all once the athlete is 2 years or longer after surgery. In two long-term follow-up studies examining participants with ACLR, the hop test was unable to discriminate between the operative and non-operative knee41 or between competitive and non-competitive athletes with ACLR 31…”
