Physically active patients with chronic lateral ligament instability shows a significant improvement in Foot and Ankle Outcome Score (FAOS) after LARS procedure.
Primary repair combined with
ligament augmentation reconstruction system (LARS) provides higher Tegner
activity scores and better total Foot and Ankle Outcome Score (FAOS) at 5-year
follow-up as compared to the modified Broström-Gould (MBG) procedure, observed
from the findings of a currently published randomized controlled trial in the
American Journal of Sports Medicine. The modified Broström-Gould (MBG) method
remains the gold standard for managing ankle sprain but associated with certain
contraindications, and the longer-term results of this method are still under
investigation. Therefore, alternative treatment was opted by the investigators
of this analysis.
The patients who matched the
inclusion criteria were selected and randomized to either LARS or MBG groups.
Both groups followed a similar postoperative rehabilitation. Foot and Ankle
Outcome Scores (FAOS) were recorded before, and one, two and five years
following the treatments. However, the Tegner activity scores were measured at
five years. Statistical analysis was used to compare both groups' scores.
Out of 50 patients, 47 completed
the analysis. MBG group involved 25 and LARS group included 21 participants.
There were no failures in the LARS group, whereas, MBG group had two failures.
The total FAOS at one, two and five years after the treatment showed better
improvement in the LARS group as compared to the MBG group. The 5-year Tegner
activity scores were also higher in the LARS group. These results indicated
that LARS treatment provides better outcomes as compared to the MBG.
