Arthroscopic ACL Reconstruction, All Inside Technique, Complete Tibial Tunnel Technique, Patient-Reported Outcomes (PROs)
Background: Anterior cruciate ligament (ACL) injuries are a common occurrence in the field of orthopedics and sports medicine, often requiring surgical intervention to restore knee stability as well as activity.
Objective: This study's objective was to compare the results of a large patient cohort undergoing ACL restoration utilizing the Complete Tibial Tunnel (CTT) approach with the All Inside Technique (AIT).
Methodology: A research conducted at many medical facilities from January 2021 to July 2023 included 80 patients, ages 18 to 45, who had MRI-confirmed ACL injuries. Two groups of patients had All Inside Group (AIG) and Complete Tibial Tunnel Group (CTTG) ACL restoration, with different surgical procedures used according to the surgeon's discretion. Standard procedures were followed throughout postoperative rehabilitation, and statistical analysis was used to evaluate results using t-tests, chi-square tests, descriptive statistics, hypothesis testing, and Kaplan-Meier survival analysis. Significance was defined as p<0.05.
Results: The research assessed the baseline characteristics, injuries, surgeries, and complications of the two groups, which consisted of 38 persons in the AI group (mean ± SD age: 24.7 ± 10.3 years) and 42 individuals in the CTTG group (mean ± SD age: 20.2 ± 6.9 years).Comparable results were seen for the Patient-Reported Outcomes (PRO) in the most frequent follow-up: Tegner activity score (6.3 vs. 5.7, with a p-value of 0.042), IKDC score (92.7 vs. 89.2, with a p-value of 0.387), and Lysholm score (92.6 vs. 90.8, with a p-value of 0.593). In general 13 of 42 participants (30.95%) in the CTTG and 4 of 38 participants (10.52%) in the AIG failed before the end of follow-up (P= 0.300). While the CTTG and AIG had a mean return to sport of 9.9 months and 11.5 months (P=0.038), respectively.
Conclusion: In conclusion, the study compared ACL reconstruction techniques, favoring the All Inside Technique (AIG) due to its slightly higher Tegner score, lower failure rate, and a slightly longer return to sport time, highlighting its potential as a promising surgical approach for improved patient outcomes.
