Correlation of Femoral Tunnel Length with Body Height, Limb Length, and Thigh Length in Indian Patients Undergoing Anterior Cruciate Ligament Reconstruction

Abstract

Purpose. To measure the femoral tunnel length created through a far medial portal and determine its correlation with body height, limb length, and thigh length in 404 Indian patients undergoing anterior cruciate ligament (ACL) reconstruction. Methods. 364 male and 40 female Indian patients aged 18 to 51 (mean, 26.8) years underwent ACL reconstruction by a single surgeon using the hamstrings tendon autograft. Their body height, limb length, and thigh length were measured by a single assessor, as was the femoral tunnel length. Results. The mean femoral tunnel length was 34.5 mm. It was <30 mm in 28 patients and <25 mm in 2 patients. The correlation coefficients of the femoral tunnel length with body height, limb length, and thigh length were 0.485 (p<0.0001), 0.426 (p<0.0001), and 0.304 (p<0.0001). No patient had posterior wall blowout fracture. Conclusion. The femoral tunnel length positively correlated with body height, limb length, and thigh length in 404 Indian patients.

Femoral Tunnel Length in Anatomical Double-Bundle Anterior Cruciate Ligament Reconstruction Is Correlated with Body Size and Knee Morphology

“…Several authors have reported on femoral tunnel length, a summary of which can be found in table 2 (Table 2) [27,28,29,30,31,32,33,34]. Regarding femoral tunnel length, the results of the present study do not differ significantly from those of previous reports.…”

“…Being able to determine the appropriate femoral tunnel length prior to surgery can reduce the risk of creating an insufficient femoral tunnel. Several authors have reported on femoral tunnel length [27,28,29,30,31,32,33,34]. However, to our knowledge, no studies have addressed the correlation between femoral tunnel length and body size and knee morphology in anatomical double-bundle ACL reconstruction.…”

“…In previous studies involving a double-bundle procedure, some report longer AM and some report longer PL tunnel length. [27], and Iriuchishima et al reported a positive correlation between tunnel length and height, body weight, and Blumensaat's line length [29]. However, correlations such as these have only been reported in studies involving single-bundle reconstruction; no correlation-related body size or knee morphology reports have involved double-bundle reconstruction.…”

Outcome of hamstring graft with preserved insertion: Prospective Study with 5 year Follow-up

“…Transportal technique was used to make femoral tunnel in all cases in both the groups [22]. Group 1 had patients who got operated with hamstring free graft [23] (Technique 2) and groups 2 patients got operated with hamstring graft with preserved insertion [16] (Technique 1).…”
