Abstract
Objectives:
This study aims to compare functional outcomes and knee stability in patients undergoing ACLR with PLT versus HT grafts.
Methods:
A cross-sectional study was conducted involving 34 patients who underwent ACLR using either PLT or HT grafts. Participants were assessed for knee stability using a Lachmeter, functional outcomes using the Knee Injury and Osteoarthritis Outcome Score (KOOS) and The American Orthopaedic Foot & Ankle Society (AOFAS) score, and radiographic measurements at six months post-surgery. Statistical analysis included chi-square, independent t-test, and Mann-Whitney U test.
Results:
A total 34 patients (23 patients with stable knee and 11 patients with unstable knee post-surgery). met inclusion criteria. The patients divided into two cohorts: PLT and HT grafts. The knee stability analysis showed no difference between PLT and HT grafts (47.8%vs52.2%, p=1.000). The PLT showed significantly better KOOS score than HT graft (p=0.019). Conversely, the AOFAS score was observed higher in HT graft compared to PLT graft (23.59 vs 11.41, p=<0.001).
Conclusion:
Although no significant difference was found in overall knee stability between PLT and HT grafts, PLT demonstrated superior results in KOOS subscales, suggesting better functional outcomes in terms of pain and sports activities. Conversely, HT grafts showed better ankle function as indicated by AOFAS scores. These findings highlight the need for individualized graft selection based on specific patient needs and activities. Both PLT and HT grafts provide viable options for ACLR, with PLT showing potential advantages in functional outcomes and HT in ankle stability. Further research with larger sample sizes and longer follow-up periods is necessary to substantiate these findings.
