Abstract

Introduction

High posterior tibial slope (PTS) has been recognised as a risk factor for anterior cruciate ligament rupture and graft failure. This prospective randomised study looked at intra-operative findings of concomitant intra-articular meniscal and chondral injuries during a planned ACL reconstruction.

Material and Methods

Prospective data was collected as part of a randomised trial for ACL reconstruction techniques. Intra-operative data was collected and these findings were compared with the PTS measured on plain radiograph by a single person twice through a standardised technique and intra-observer analysis was performed.

Results

49 confirmed ACL rupture patients were in the trial. The average age was 34 (23–66) years and 12 patients were female. 17 patients (34%) had PTS of 12 degrees or more. The intra-observer analysis for PTS measurements in a 2-sided paired T test, showed a mean difference of 0.03 degrees with a P value = 0.83.

23 patients had medial meniscal pathology identified, 15 (65%) had a PTS <12 degrees. 16 patients had lateral meniscus pathology and 9 (56%) had a PTS <12 degrees. Chondral damage did not appear significantly different in the two groups (<12 degrees 15% vs >12 degrees 23%).
