We describe the technical aspects of an arthroscopy-assisted procedure indicated for the management of acute unstable acromioclavicular joint injuries, consisting of a synthetic augmentation of both the coracoclavicular and acromioclavicular ligaments, that anatomically reproduces the coracoclavicular biomechanics and offers fixation that keeps the torn ends of the ligaments facing one another, thus allowing healing of the native structures without the need for a second surgical procedure for metal hardware removal.
The authors regret that they made a mistake when writing the figure legends of Figs. 3 and 4. Both magnetic resonance images were showing the lateral instead of the medial compartment of the knee.The authors would like to apologise for any inconvenience caused.
Objectives:To evaluate the influence of chondral lesions of the knee in function and appearance on magnetic resonance imaging (MRI) of the meniscal implant Polyurethane (Actifit®).Material and Methods:48 patients were implanted with Actifit® by postmeniscectomía syndrome. The chondral status of their respective compartment was graded at arthroscopy with ICRS scale. Were evaluated functionally Womet, IKDC, Kujala, EVA and satisfaction (0-4). The implant characteristics were evaluated with MRI scale Genovese, assessing its correlation with the degree of chondral damage and functional outcomeResults:Mean follow-up of 38 months (25-75). 16 patients had no chondral lesion, 14 had lesion grade II, 10 grade III and IV grade 9. Womet, Kujala improved IKDC and 36.2 ± 7.6, 32.3 ± 13.5 and 39.2 ± 8.1 to 75.8 ± 12.9 (p = 0.02), 75.5 ± 15.4 (p = 0.03) and 85.6 ± 13.4 (0.042), respectively. No relationship between the degree of chondral damage and functional outcome was observed. The shape and size of the implant in RM was worse with higher levels of chondral lesion (p = 0.023). A post-hoc analysis showed that this was only due to the difference between patients without chondral injury versus those with ICRS II-IV. The satisfaction was 3.6 ± 0.8 points.Conclusion:Implementing a Actifit® led to significant pain and functional improvement after a minimum follow-up of 2 years. The size and morphological MRI appearance of meniscal replacement polyurethane was better in patients without chondral lesions. No relationship between the degree of chondral damage and functional outcome was observed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
