The role of the anterolateral ligament in knee ’s biomechanics: a case–control retrospective study

AbstractPurposeThe aim of this study was to assess the functional and clinical results of patients who underwent ACL reconstruction surgery and were divided into subpopulations related to ACL-associated lesions and focused on ALL-associated lesion.MethodsOur retrospective analysis included 62 patients who underwent standard ACL reconstruction surgery in our hospital from 2014 to 2016. The mean follow-up period was 21  months (range 11–35). We divided the sample into two subpopulations due to the presence or absence of ALL tear at the preoperative MRI. In 42 patients out of 62 (68%), ALL lesion was evident. We evaluated in both subpopulations the ACL failure rate, the functional outcomes rated with IKDC, KOOS, Lysholm scores and the clinical assessment of anteroposterior and rotatory instability with the Lachman test and pivot-shift test.ResultsThe overall re-injury rate in our cohort of patients was 4.8% with a smaller but not a significant difference between the two groups. A statistically significant difference was observed for the three functional scores, favoring the isolated ACL-lesion group (p

The objective and subjective outcomes at 2  years are presented.MethodsPaediatric patients, less than 16  years of age, presenting acutely with complete proximal ACL ruptures underwent direct arthroscopic ACL repair, reinforced by a temporary internal brace, which was subsequently removed after 3 months. Patient-reported outcome measures including the Lysholm, Tegner and KOOS scores were collected at 6 months, 1 year and 2 years post-operatively.ResultsTwenty patients (age 6 –16) completed data at 2 years post-operatively. There were no failures, no complications and no growth distu...

We describe a technique combining the advantages of both techniques with an autograft using the semitendinosus and repair of the remnant. This combined technique allows protection and redirection of the remnant, improves graft incorporation, and covers more graft by suturing the remnant around an autologous graft.

Authors: Spang RC, Getgood A, Strickland SM, Amendola AN, Gomoll AH Abstract This review focuses on the management of anterior cruciate ligament (ACL) reconstruction patients when other concomitant pathology may need to be addressed at the time of surgery. Given the role of the posterior horn of the medial meniscus in preventing osteoarthritis progression and contributing to knee stability, medial meniscus repair should always be considered when performing ACL reconstruction. Meniscal transplant may also be appropriate in select patients with normal knee alignment and absent of cartilage abnormalities in the compar...

J Knee Surg DOI: 10.1055/s-0040-1701220Lateral extraarticular procedures (LEAPs) in the anterior cruciate ligament (ACL)-injured knee were widely abandoned in the 1990s but have seen a recent resurgence. The aim of this review was to demonstrate that anterolateral ligament reconstruction (ALLR) is associated with evidence of significant advantages and no evidence of historical concerns. A narrative review of the literature was performed. Combined ACL + ALLR is associated with improved outcomes when compared against isolated ACL reconstruction, including a significantly lower risk of ACL graft rupture (hazard ...

ConclusionThe progression of post-traumatic chondral damage may occur at a faster rate in patients who require ACL reconstruction and meniscal repair than in patients with intact menisci.

ConclusionThe minimum 5  years survival rate after primary ACL repair using this technique was 70%. This value dropped to 56% in highly active patients performing competitive sports. Patients not suffering failure of repair demonstrated adequate restoration of knee laxity and high satisfaction. This study not only underli nes the potential of ACL repair, but also highlights the danger of the procedure if strict patient selection is not appreciated.Level of evidenceLevel IV.

CONCLUSION: A well-designed database and user-friendly interface have greater potential for research utility, clinical efficiency, and, thus, cost-effectiveness when compared with standard voice-dictated operative notes. Widespread utilization of such tools can accelerate the pace and improve the quality of orthopaedic clinical research. LEVEL OF EVIDENCE: Level IV. PMID: 31977610 [PubMed - in process]

Medical technology is revolutionizing healthcare for patients worldwide and is now more than ever becoming crucial in the prevention, diagnosis, treatment, and management of numerous diseases. We are increasingly seeing the ability of medical technology to personalize treatments and target patients’ individual needs. However, to ensure we are enabling access to these treatments, regulatory agencies need to consider new approaches to the approval process. Historically, product approvals have focused on the standardization of a drug or a therapy to treat a large population of people with the same disease, s...

CONCLUSIONS Anterior cruciate ligament suture with the InternalBrace ligament augmentation judging from the results achieved by our group of patients brings very good clinical outcomes already at 6 months postoperatively. This method allows the athletes to return to full load soon. It maintains the kinematics and knee joint proprioception, and thus can potentially contribute to the prevention of post-traumatic arthritis. Strict application of indication criteria is a precondition to success. A longer follow up and evaluation of a larger number of patients will, however, be necessary to definitely confirm the success of thi...
