- Abstract
- The aim of this study was to compare the results of two different methods of posterolateral corner reconstruction (fibular head tunnel versus tibial tunnel), performed at the same time as a posterior cruciate ligament reconstruction. Between January 1999 and October 2003, 47 patients underwent tensioning of a remnant posterior cruciate ligament and anterolateral bundle reconstruction along with a posterolateral corner reconstruction using a fibular head bone or tibial bone tunnel. Thirty-nine patients determined to be eligible were enrolled in this retrospective study after a minimum follow-up duration of 2 years. The average duration of follow-up was 35.3 months (range 24-70 months). Satisfactory results were achieved in 32 patients (82%) according to the International Knee Documentation Committee(IKDC) scores, and 29 patients (74%) had restored external rotational stability. The fibular head tunnel was superior to the tibial tunnel method in terms of operation time (43.0 +/- 15.7 vs. 66.6 +/- 9.4 min, respectively, P < 0.001) and improved rotational stability (85 vs. 65%, respectively, P = 0.007). However, there were no significant differences seen in anteroposterior stability and clinical assessments [Orthopadische Arbeitsgruppe Knie (OAK) P = 0.277 and IKDC scores P = 0.564]. In grade 2 chronic posterolateral rotatory instability with little or no varus instability associated with injury to the posterior cruciate ligament, a posterolateral reconstructive procedure with a single sling through the fibular tunnel offers advantages of less surgical morbidity and operation time, as well as better rotational stability, over reconstruction through the tibial tunnel.
