Background: Deep venous thrombosis (DVT) and pulmonary embolism are serious potential complications after anterior cruciate ligament reconstruction (ACLR). Little is known about the influence of tourniquet use on the incidence of DVT after ACLR. Purpose: To compare the incidence of DVT after ACLR with and without the use of a tourniquet. Study Design: Cohort study; Level of evidence, 3. Methods: Between November 2018 and May 2020, a total of 60 consecutive ACLRs in 60 patients, including 7 revision surgeries, were performed without tourniquet use at our hospital and were enrolled in this study (T– group). In addition, 55 consecutive ACLRs in 55 patients, including 10 revision surgeries, were performed with tourniquet use between April 2017 and September 2018 and were enrolled as the control group (T+ group). DVT was diagnosed using ultrasonography of both legs performed preoperatively and at postoperative week 1. The incidence of postoperative DVT was compared between the T– and T+ groups. Logistic regression analysis was performed to evaluate the effect of older age (≥40 vs <40 years) and tourniquet use on the occurrence of DVT. Results: No DVTs were detected preoperatively. The incidence of postoperative DVT was significantly lower in the T– group compared with the T+ group (1 patient [1.7%] vs 9 patients [16.4%]; P = .005). All patients with DVT were asymptomatic. Although the mean operative time was not significantly different (80.8 minutes in the T+ group vs 78.5 minutes in the T– group; P = .461), the mean blood loss from the drain was significantly lower in the T– group than in the T+ group (149.9 vs 201.9 mL; P < .001). Age ≥40 years and tourniquet use were significantly related to the occurrence of DVT (odds ratio, 8.3 [95% CI, 1.9-36.8]; P = .005; and odds ratio, 8.8 [95% CI, 1.0-75.3]; P = .047, respectively). Conclusion: ACLRs performed without tourniquet resulted in a significantly lower incidence of DVT after ACLR and significantly less bleeding from drains. If adequate visibility of the surgical field is obtained, ACLR without tourniquet use may reduce the incidence of DVT.

Background: Anterior cruciate ligament reconstruction (ACLR) with hamstring autograft has gained popularity. However, an unpredictably small graft diameter has been a drawback of this technique. Smaller graft diameter has been associated with increased risk of revision, and increasing the number of strands has been reported as a successful technique to increase the graft diameter. Purpose: To compare failure rates of 5-strand (5HS) and 6-strand (6HS) hamstring autograft compared with conventional 4-strand (4HS) hamstring autograft. We describe the technique in detail, supplemented by photographs and illustrations, to provide a reproducible technique to avoid the variable and often insufficient 4HS graft diameter reported in the literature. Study Design: Cohort study; Level of evidence, 3. Methods: We retrospectively reviewed prospectively collected data of all primary hamstring autograft ACLRs performed at our institution with a minimum 2-year follow-up and 8.0-mm graft diameter. A total of 413 consecutive knees met the study inclusion and exclusion criteria. The study population was divided into 5HS and 6HS groups as well as a 4HS control group. The primary outcome was failure of ACLR, defined as persistent or recurrent instability and/or revision ACLR. Results: The analysis included 224, 156, and 33 knees in the 5HS, 6HS, and 4HS groups, respectively. The overall ACLR failure rate in this study was 11 cases (8%): 5 cases for 5HS, 3 cases for 6HS, and 3 cases for 4HS. No statistically significant differences were found among groups ( P = .06). The mean graft diameter was 9 mm, and the mean follow-up was 44.27 months. Conclusion: The 5HS and 6HS constructs have similar failure rates to the conventional 4HS construct of 8.0-mm diameter and are therefore safe and reliable to increase the diameter of relatively smaller hamstring autografts. We strongly recommend using this technique when the length of the tendons permits to avoid failures reportedly associated with inadequate graft size.

ABSTRACT Aim To evaluate whether a daily full-dose aspirin regimen after anterior cruciate ligament (ACL) reconstruction reduces the risk of postoperative symptomatic deep-venous thrombosis (DVT). Materials and Methods Single-center retrospective cohort study of patients who underwent ACL reconstruction from 2007 to 2016. One thousand two hundred thirty-three patients met inclusion criteria: 821 patients received no chemoprophylaxis and 412 patients received daily full-dose aspirin. Results A total of 10 patients, seven receiving no chemoprophylaxis and three using aspirin, sustained a postoperative symptomatic DVT. Calculated adjusted odds ratio for symptomatic postoperative DVT for aspirin versus no chemoprophylaxis was 0.928 (95% CI 0.237-3.629, P value = 0.91). Odds ratio for symptomatic postoperative DVT occurrence among tobacco users versus non-tobacco users was 3.76 (95% CI 1.077-13.124, P = 0.04). Conclusions No statistically significant difference was observed in postoperative symptomatic DVT after ACL reconstruction in those who received full-dose aspirin chemoprophylaxis versus those with no chemoprophylaxis. Additionally, there was a significantly increased risk of postoperative symptomatic DVT with tobacco use.

SummaryA dimorphism in the 3’-untranslated region of the prothrombin gene (G to A transition at position 20210) has recently been reported to be associated with increases in plasma prothrombin levels and in the risk of venous thrombosis (1). We have examined the prothrombin dimorphism among 99 unselected outpatients with phlebography verified deep venous thrombosis, and in 282 healthy controls. The prevalence of the 20210 A allele was 7.1% (7/99) in the patient group, and 1.8% (5/282) in the healthy control group (p = 0.0095). The relative risk of venous thrombosis was calculated to be 4.2 (95% Cl, 1.3 to 13.6), and was still significant when adjustment was made for age, sex and the factor V:R506Q mutation causing APC resistance [odds ratio 3.8 (95% Cl, 1.1 13.2)]. As previously reported, 28% of the patients were carriers of the factor V:R506Q mutation. Thus, 34% (one patient carried both traits) of unselected patients with deep venous thrombosis were carriers of an inherited prothrombotic disorder. To sum up, our results confirm the 20210 A allele of the prothrombin gene to be an important risk factor for venous thrombosis.

BACKGROUND: Anterior Cruciate Ligament (ACL) remnants have important biomechanical, vascular and proprioceptive function.AIM: To determine the influence of the ACL residual remnants after partial and complete ACL ruptures on postoperative clinical results in patients with remnant preserving ACL reconstruction.PATIENTS AND METHODS: The study included 66 patients divided into two groups. In patients from the investigation group remnant preserving ACL reconstruction was performed, in patients from the control group single bundle ACL reconstruction was performed. The results were assessed by Rolimeter measurements, Lysholm and Tegner scores and proprioception evaluation.RESULTS: The mean side-to-side difference of anterior tibia displacement (mm) was improved from 4.4 ± 1.06 to 0.4 ± 0.7 in the investigation group, and from 4.6 ± 0.68 to 1.9 ± 0.64 in the control group (p < 0.001). Difference in the angles in which the knee was placed by the device and the patient has improved from 1.5 ± 0.96° to 0.5 ± 0.53° in the investigation group and from 1.8 ± 0.78° to 1.3 ± 0.97° in the control group (p < 0.05).  Tegner and Lysholm scores showed no difference between the groups.CONCLUSION: Preservation of the ACL residual bundle provides a better knee stability and proprioceptive function.

ABSTRACT Introduction In long-term sports, especially in explosive sports such as accelerated starting, athletes are prone to rupture the anterior cruciate ligament (ACL). It is the ultimate goal of ACL reconstruction for athletes to restore the stability (static and dynamic) and mechanical structure of the knee joint through reconstruction surgery. Object This article uses ACL reconstruction to repair patients’ ACL and explores the effect of athletes’ nerve recovery after sports. Methods We collected 35 ACL reconstruction athletes and randomly divided them into two groups (experimental group, 18; control group, 17). After reconstruction, the athletes in the experimental group were treated with sports rehabilitation. Results The experimental and control groups had great differences in knee joint exercise indexes and nerve function recovery. Conclusion Sports rehabilitation training can effectively improve the nerve function of the knee joint after ACL reconstruction. Level of evidence II; Therapeutic studies - investigation of treatment results.

Bony morphologic characteristics have been demonstrated to increase the risk of anterior cruciate ligament (ACL) injury. The purpose of the study was to examine distal femoral morphology relative to ACL injury, reconstruction failure, and contralateral ACL injury. It was hypothesized that an increased posterior femoral condylar depth, quantified as the tomahawk ratio, would correlate with increased risk of primary ACL ruptures, ACL reconstruction failures, and contralateral ACL injuries. Consecutive patients undergoing arthroscopic knee surgery at an academic medical center from 2012-2016 with minimum 24-month follow-up were retrospectively reviewed. Subjects were stratified into four groups: a control group consisting of patients with no ACL injuries and three groups of patients with a primary ACL injury, failed ACL reconstruction, or previous ACL injury with subsequent contralateral ACL injury. Using lateral radiographs, the ratio of posterior condylar depth over total condylar distance was defined as the tomahawk ratio. Analysis-of-variance (ANOVA) and post-hoc testing were used to test for differences in the mean tomahawk ratio between study groups (p<0.05). Receiver Operating Characteristic (ROC) analysis was performed to determine the optimal tomahawk ratio cut-off for detecting increased risk for ACL injury 175 patients met inclusion criteria. The mean tomahawk ratios in the control group, primary ACL injury group, failed ACL reconstruction group, and contralateral ACL injury group were 61.1% (± 2.1), 64.2% (± 3.8), 64.4% (± 3.6), and 66.9% (± 4.0), respectively. Patients with a primary ACL injury, failed ACL reconstruction, or contralateral ACL injury had a significantly higher tomahawk ratio compared to the control group (p<0.008). ROC analysis demonstrated a tomahawk ratio of 63% or greater to be associated with an increased risk for ACL injury with a sensitivity of 83% and a specificity of 71%. The data from this study show that an increased posterior femoral condylar depth, or tomahawk ratio, is associated with increased risk of ACL injury, including primary ACL injury, failed ACL reconstruction, and contralateral ACL injury. Readily identifiable risk factors, such as an increased tomahawk ratio, could assist clinicians in identifying at-risk individuals who may experience greater benefit from targeted ACL injury prevention counseling and intervention. The presence of the tomahawk-shaped femur could also be used to guide treatment decisions and identify ACL reconstruction patients who may benefit from additional surgical procedures such as extra articular tenodesis.
