RESUMO
PURPOSE: Suspensory devices are extensively used in the management of anterior cruciate ligament (ACL) tear. They include fixed- and adjustable-loop devices. There are only a few studies comparing the efficacy of these two devices in the available literature. Therefore, the aim of this study is to compare clinical outcomes between the adjustable-loop device (group I) and fixed-loop device (group II). MATERIALS AND METHODS: This was a prospective randomized study. Both groups were equivalent in demographic, preoperative, and intraoperative variables. Twenty-three patients underwent femoral side graft fixation with adjustable-loop and 20 with fixed-loop devices. Four patients were lost to follow-up. Assessment of clinical outcome was done with International Knee Documentation Committee (IKDC) score, Lysholm score, and knee stability tests (Lachman test and pivot shift test). Patient evaluation was performed preoperatively and finally postoperatively 2 years after surgery. RESULTS: Postoperative IKDC scores of group I and II were 91.9 ± 3.6 and 91.5 ± 3.6, respectively, and Lysholm scores were 91.0 ± 3.6 and 91.4 ± 3.5, respectively, after 2 years; however, the difference in the outcomes was statistically insignificant (p > 0.05). Twenty patients (87%) in group I and 17 patients (85%) in group II had a negative Lachman test (p = 0.8). Twenty-two patients (95.7%) in group I and 19 patients (95%) in group II had a negative pivot shift test (p = 0.9). CONCLUSION: ACL reconstruction with fixed- and adjustable-loop suspensory devices for graft fixation gives equivalent and satisfactory clinical results. LEVEL OF EVIDENCE: 1.
RESUMO
BACKGROUND: The literature is gradually drifting towards a graft of larger diameter for successful ACL reconstruction. There is no published literature regarding the anthropometric predictors for the diameter of the peroneus longus tendon (PLT) graft obtained in ACL reconstruction through the inframalleolar approach. METHODS: Fifty-two patients were finally evaluated for anthropometric parameters to predict quadrupled PLT graft diameter in ACL reconstruction using the inframalleolar technique. Intraoperative quadrupled PLT graft diameter was correlated to the patient's anthropometric data such as age, height, weight, duration of injury, and BMI. We used regression analysis in a stepwise manner to ascertain anthropometric indices associated with the graft diameter. RESULTS: This study included 46 males and six females. Mean age was 28.2 ± 7.4 years, mean height was 172.7 ± 2.8 cm, mean weight was 75.6 ± 3.4 kg, mean BMI was 25.3 ± 0.9 kg/m2, mean duration of injury was 9.2 ± 3.9 months, and mean graft diameter was 9.3 ± 0.4 mm. Positive correlation with graft diameter was found only with height (r = 0.6, P < 0.01) and weight (r = 0.4, P < 0.01). On analysing through linear regression, height and weight had significant association with graft diameter, and we formulated the following prediction equation: PLT graft diameter (mm) = 0.083 × height (cm) + 0.011 × weight (kg) -5.854. CONCLUSION: Patients' characteristics, including height and weight, have a significant correlation with quadrupled PLT graft diameter and the average diameter of graft is > 9 mm through this approach.
