Five-Strand Hamstring Autograft in Primary Anterior Cruciate Ligament Reconstruction

J Knee Surg DOI: 10.1055/s-0038-1641175The purpose of this study was to describe our surgical technique of using five-strand hamstring autograft with interference screw fixation in primary anterior cruciate ligament (ACL) reconstruction and to report the early postoperative outcomes of this technique. Patients who underwent primary ACL reconstruction using five-strand hamstring autografts with interference screw fixation between December 2014 and June 2016 were included in this study. The five-strand configuration was used in these patients because the four-strand configuration produced a graft diameter of less than 8 mm. Subjective questionnaires, including the Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Lysholm Score, were administered preoperatively, as well as at 1- and 2-year follow-ups. Paired t-test was used to compare the pre- and postoperative outcome scores. The study group comprised 25 patients. There were no intraoperative complications. The mean follow-up period was 17.8 months (12–24). There were 19 males and 6 females. The median age was 24 years (16–41), and median body mass index was 23.9 (18.5–30.2). The median diameter of the five-strand graft was 9 mm (8–10 mm), with a mean of 9.06 ± 0.60 mm. This was associated with a median graft length of 90 mm (80–100 mm). The postoperative Lysholm, KOOS symptoms, KOOS Pain, KOOS daily function, KOOS sports function, KOOS quality of life, ...

ConclusionsThe findings of this study showed that anterior knee laxity is restored with revision BPTB autograft ACLR after failed primary HT autograft ACLR, in the same cohort of patients. However, revision ACLR showed a significantly inferior functional knee outcome compared with primary ACLR. It is important for clinicians to inform and set realistic expectations for patients undergoing revision ACLR. Patients must be aware of the fact that having revision ACLR their knee function will not improve as much as with primary ACLR and the final postoperative functional outcome is inferior.Level of evidenceRetrospective cohort study, Level III.

AbstractPurposeTo compare anterior knee laxity and patient-reported outcome measures (PROMs) between anterior cruciate ligament reconstruction (ACLR) performed with bone –patellar tendon–bone (BPTB) and hamstring tendon (HT) autografts and, moreover, to study any correlation between postoperative anterior knee laxity and PROMs.MethodsPatients who underwent primary ACLR at Capio Artro Clinic, Stockholm, Sweden, from January 2000 to October 2015, were identified in our local database. Instrumented laxity measurements and PROMs were reviewed. The KT-1000 arthrometer, with an anterior tibial load of 134-N, was used...

This study aimed to compare the outcomes of isolated ACL reconstruction using the patellar tendon (PT) autograft and the hamstring (HT) autograft in 180 patients over 20 years. Study Design: Cohort study; Level of evidence, 2. Methods: A total of 180 participants undergoing isolated ACL reconstruction between 1993 and 1994 were prospectively recruited. Evaluation was performed at 1, 2, 5, 7, 10, 15, and 20 years after surgery and included the International Knee Documentation Committee (IKDC) knee ligament evaluation with radiographic evaluation, KT-1000 arthrometer side-to-side difference, and subjective scores. Results...

Background: The administration of nonsteroidal anti-inflammatory drugs (NSAIDs) to patients undergoing anterior cruciate ligament reconstruction (ACLR) is controversial because it may impair tissue healing and clinical outcomes. Purpose: To assess the effect of NSAID administration on patients undergoing ACLR. Study Design: Cohort study; Level of evidence, 3. Methods: Included patients were aged>15 years and were registered in the Norwegian Knee Ligament Registry from 2008 until 2013 after the primary ACLR. Patients with insufficient data regarding administration of NSAIDs and those with associated knee ligament inju...

Authors: Witoński D, Kęska R, Cyranowski R, Paradowski PT Abstract INTRODUCTION: Several studies have suggested that anterior cruciate ligament reconstruction (ACLR) without wound drainage has no impact on long-term follow-up. AIM: To investigate a prospective patient series as measured by the patient-administered disease-specific questionnaire Knee injury and Osteoarthritis Outcome Score (KOOS). MATERIAL AND METHODS: The study included 101 consecutive patients (71 men and 30 women) with a mean age of 30 years (SD 10, range: 15-62 years), who had undergone primary single incision arthroscopic bone-patella...

Background: The "initial graft tension" applied at the time of graft fixation during anterior cruciate ligament (ACL) reconstruction surgery modulates joint contact mechanics, which in turn may promote posttraumatic osteoarthritis (OA). Purpose/Hypotheses: The study objectives were to compare clinical, functional, patient-reported, and OA imaging outcomes between 2 different initial laxity-based graft tension cohorts and a matched uninjured control group as well as to evaluate the effects of laxity-based graft tension on OA development at 84-month follow-up. The 2 laxity-based tension protocols were (1) to resto...

J Knee SurgDOI: 10.1055/s-0036-1584538Femoral nerve block (FNB) has been proposed for pain control following anterior cruciate ligament (ACL) reconstruction. Although numerous studies have assessed the efficacy of FNBs, there has been little to no research into the effect of such blocks on postoperative strength and patient-reported outcomes. We hypothesized that performance of an FNB would result in decreased quadriceps strength and poorer patient-reported outcome scores within the first 6 months following ACL reconstruction. A total of 30 patients scheduled to undergo hamstring autograft ACL reconstruction following an a...

Background: Long-term prospective follow-up studies of single-incision endoscopic anterior cruciate ligament (ACL) reconstruction are limited and may include confounding factors. Purpose: This longitudinal prospective study reports the outcomes of isolated ACL reconstruction using middle-third patellar tendon autografts in 90 patients over 20 years. Study Design: Case series; Level of evidence, 4. Methods: Between January 1993 and April 1994, a total of 90 patients met study inclusion criteria: evaluation at 1, 2, 3, 4, 5, 7, 10, 15, and 20 years after surgery. Exclusion criteria were associated ligamentous injuries req...

Conclusion ACL reconstruction significantly improves clinical results and stability of the knee. Difference in Lysholm score and stability between groups was not significant. Neither group showed higher tendency to graft failure within two years. Graft choice for reconstruction in female patients should be surgeon specific and individualised, as both grafts studied achieved comparable results.
