Stress Radiography for Multiligament Knee Injuries: A Standardized, Step-by-Step Technique.

ABSTRACT: Physical examination in the presence of a multiligament knee injury can be complex and challenging. Hence, stress radiography is a useful and inexpensive tool that is widely used in the assessment of this type of injury. It guarantees an objective analysis of the magnitude of knee instability, which may reduce the observer's interpretation bias in relation to the physical examination. However, for the radiographic analysis to be reproducible, it is necessary to standardize the technique to evaluate each of the main knee ligaments. This article aims to describe in detail how to perform stress radiography to assess the sufficiency of the posterior cruciate ligament and collateral ligaments in the context of a multiligament injury.

Project description:All-arthroscopic tibial inlay double-bundle (DB) posterior cruciate ligament (PCL) reconstruction avoids an open dissection and the "killer turn" while maintaining the advantage of an anatomic graft. However, clinical data on the viability of this surgical technique in multiligamentous knee injuries are lacking.At greater than 2 years of followup, we evaluated (1) validated outcomes scores; (2) range of motion; and (3) side-to-side stability on PCL stress radiographs of a small group of patients who underwent all-arthroscopic tibial inlay DB PCL reconstruction in multiligamentous knee injuries, either shortly after injury or late.All patients sustaining an operative multiligamentous knee injury between August 2007 and March 2009 underwent PCL reconstruction with the all-arthroscopic tibial inlay DB PCL reconstruction. Twelve patients sustained such injuries and were reconstructed during the study period and all 12 returned for followup with a minimum of 2 years (mean 3 ± 0.8 years). There were nine males and three females, with a mean age of 30 years; four patients had a subacute reconstruction (? 3 weeks, but < 3 months), and eight patients had chronic reconstructions (> 3 months). Mean time from injury to PCL reconstruction was 7 ± 12 months. Demographics, ROM, outcome scores (Lysholm and International Knee Documentation Committee [IKDC] scores), and PCL stress views were obtained.At final followup, mean Lysholm and IKDC subjective scores were 79 ± 16 and 72 ± 19, respectively. IKDC objective scores included eight nearly normal knees, three abnormal knees, and one severely abnormal knee. Mean flexion and extension losses compared with the contralateral were 10 ± 9 and 1 ± 2, respectively. Mean ± SD final side-to-side difference on PCL stress radiographs was 5 ± 3 mm.The clinical and radiographic results of the all-arthroscopic tibial inlay DB PCL reconstruction appear comparable to the same technique in isolated PCL injuries and, based on similar published case series, comparable to results of multiligamentous knee reconstructions using other PCL reconstruction techniques.Level IV, therapeutic study.

Project description:PurposeThe purpose of this study was to compare clinical outcomes and incidence of concomitant injuries in patients undergoing early vs delayed surgical treatment of single anterior cruciate ligament (ACL) injury and multiligament knee injury (MLKI).MethodsA literature search using PubMed, Embase, the Cochrane Library, the Cumulative Index to Nursing and Allied Health, and Scopus from their inception to April 30, 2020 was conducted. Studies with levels I to IV evidence reporting the incidence of meniscus or cartilage injury according to early vs delayed surgery in single ACL injuries and MLKIs were included. In the meta-analysis, data based on the number of meniscus and cartilage injuries were extracted and pooled. Lysholm and Tegner scores were analyzed using two-sample Z-tests to calculate the non-weighted mean difference (NMD). A meta-regression analysis was also performed to determine the effect of single ACL injury and MLKI/study design.ResultsSixteen studies on single ACL injury and 14 studies on MLKI were included in this analysis. In the analysis, there were significant decreases in Lysholm score (NMD - 5.3 [95% confidence interval (CI) - 7.37 to - 3.23]) and Tegner score (NMD - 0.25 [95% CI - 0.45 to - 0.05]) and increases in risk of meniscus tear (odds ratio [OR] 1.73 [95% CI 1.1-2.73], p = 0.01) and cartilage injury (OR 2.48 [95% CI 1.46-4.2], p = 0.0007) in the delayed surgery group regardless of single ACL injury or MLKI. The result of the meta-regression analysis indicated that single ACL injury and MLKI/study design were not significant moderators of overall heterogeneity (p > 0.05).ConclusionsOur study suggests that delayed ACL surgery significantly resulted in a higher risk of meniscus tear and cartilage injury and decreased Lysholm and Tegner scores compared to early ACL surgery. The Lysholm scores in the delayed MLKI surgery group were significantly decreased, but the risks of meniscus tear and cartilage injury in the delayed MLKI surgery group remained unclear.Level of evidenceLevel III, meta-analysis.
