Background: Medical cannabis use is an emerging topic of interest in orthopedics. Although there is a large amount of literature on medical cannabis use for managing various types of pain, few studies have focused on orthopedic conditions. There is little high-quality evidence in core orthopedic areas. The objective of this study was to summarize the literature on the efficacy of cannabis use for pain related to orthopedic conditions. Methods: We conducted a systematic review of the literature on the use of cannabinoids for pain management in core orthopedic conditions. Two independent reviewers extracted information on reporting quality, risk of bias, drugs, population, control, duration of study, pain outcomes and the authors' conclusions regarding efficacy for pain outcomes. Results: We identified 33 orthopedic studies, including 21 primary studies and 12 reviews. Study quality was generally low to moderate. Six of the included studies had a control group and 15 were noncontrolled studies. Methodologies, drugs and protocols of administration varied greatly across studies. Study conclusions were generally positive in noncontrolled studies and mixed in controlled studies. Studies using higher doses tended to conclude that cannabis use was effective, but the potential for harmful effects may also be increased with higher doses. Conclusion: Variability in the methodologies used in cannabis research makes it challenging to draw conclusions about dosing, routes and frequency of administration. Most of the existing evidence suggests that medical cannabis use is effective, but this efficacy has been demonstrated only when either there is no comparator or cannabis is compared with placebo. Studies using an active comparator have not demonstrated efficacy. Future research should focus on improving study reporting and methodologic quality so that protocols that optimize pain control while minimizing harmful effects can be determined. Contexte : La consommation de cannabis à des fins médicales est un sujet d'intérêt émergent en orthopédie. Malgré l'existence d'un important corpus de littérature médicale sur l'utilisation du cannabis pour traiter divers types de douleurs, peu d'études ont porté sur les problèmes orthopédiques. On dispose de peu de données probantes de grande qualité relatives aux principaux domaines de l'orthopédie. L'objectif de cette étude était de résumer la littérature sur l'efficacité du cannabis à soulager les douleurs orthopédiques. Méthodes : Nous avons réalisé une revue systématique de la littérature sur l'utilisation des cannabinoïdes pour la prise en charge de la douleur associée aux principaux problèmes orthopédiques. Deux examinateurs indépendants ont extrait l'information sur la qualité des rapports, le risque de biais, les médicaments, les populations et groupes témoins, la durée des études, les scores de douleur et les conclusions des auteurs quant à l'efficacité au plan des scores de douleur. Résultats : Nous avons recensé 33 études orthopédiques, dont 21 études primaires et 12 revues. La ...
Purpose Multiple studies have shown higher failure rate and patient-reported outcomes to be significantly worse following revision anterior cruciate ligament reconstructive (ACLR) surgery, especially using allografts. One of the reasons being rotational instability. Because of this, augmentation with lateral extra-articular tenodesis (LET) is often considered. Good short-term results in regards to functional and perceived scores and low complication rate can be expected in revision ACLR using allografts in combination with LET. Methods Between 2014 and 2021, 46 patients were registered for revision ACLR using allografts and extra-articular augmentation (modified Lemaire) and included in this prospective study. Patients’ demographic and clinical data were collected preoperatively, postoperatively, and during the follow-up period of 12 months. Results Patient-reported functional outcomes were statistically significant for IKDC, Lysholm, and SF-12 physical scale (p < 0.05). Tegner score showed a decreased number of patients who were able to return to sport at their previous level (p = 0.001). Stability examination tests (Lachman and pivot-shift) showed significant improvements. Concomitant lesions were present in 76.1% of patients. Ten patients (21.7%) presented major complications, including six cases of anteroposterior instability, three cases of knee pain and one graft re-rupture. Conclusion Revision procedures are inherently challenging with a high number of associated chondral and meniscus lesions. However, good short-term functional outcomes and enhanced rotational stability with an acceptable complication rate can be expected in most cases where revision ACLR using allografts is augmented with LET. Study design Prospective; Case series; Level of evidence IV.
