      error scoring system study.

AB  - CONTEXT: The Landing Error Scoring System (LESS) is a clinical evaluation of 
      jump-landing mechanics and may provide useful information in assisting with 
      return-to-sport decisions in patients after anterior cruciate ligament 
      reconstruction (ACLR). However, it is currently unknown how patients with ACLR 
      perform on the LESS compared with healthy controls. OBJECTIVE: To determine if 
      the total LESS score differed between individuals with ACLR and healthy controls 
      and to determine the types of errors that differ between groups. DESIGN: 
      Cross-sectional study. SETTING: Research laboratory. PATIENTS OR OTHER 
      PARTICIPANTS: A total of 27 individuals with unilateral ACLR (age = 19.8 +/- 1.8 
      years, height = 170 +/- 5.5 cm, mass = 68.8 +/- 11.9 kg) and 27 controls (age = 20.5 
      +/- 1.7 years, height = 169 +/- 8.4 cm, mass = 66.6 +/- 9.0 kg) with no history of 
      ACLR. INTERVENTION(S): Each participant completed 3 trials of a standardized 
      jump-landing task. MAIN OUTCOME MEASURE(S): Each jump landing was assessed for 
      specific postures using standardized LESS criteria by a blinded evaluator. 
      Individual LESS items were summed to create a total LESS score. The dominant limb 
      was assessed in the control group, and the reconstructed limb was assessed in the 
      ACLR group. RESULTS: The ACLR group had higher LESS scores compared with controls 
      (ACLR: 6.7 +/- 2.1 errors, control: 5.6 +/- 1.5 errors, P = .04). Additionally, the 
      ACLR group was more likely to err when landing with lateral trunk flexion (Fisher 
      exact test, P = .002). CONCLUSIONS: Individuals with ACLR had worse landing 
      mechanics as measured by the LESS. Lateral trunk deviation may be related to 
      quadriceps avoidance in the reconstructed limb or poor trunk neuromuscular 
      control. The LESS is useful for evaluating landing errors in patients with ACLR 
      and may help to identify areas of focus during rehabilitation and before return 
      to sport.
