We evaluated the risk factors of deep venous thrombosis (DVT) after knee arthroscopic posterior cruciate ligament (PCL) reconstruction in patients with only PCL injury. From August 2014 to December 2020, a total of 172 patients who had accepted knee arthroscopic PCL reconstruction underwent the color Doppler ultrasound of bilateral lower-extremities deep veins on 3 days postoperatively. Based on the inspection results, patients were divided into DVT group (18 males and 8 females, mean age 43.62 years) and non-DVT group (108 males and 38 females, mean age 33.96 years). The potential associations of DVT risk and age, gender, body mass index (BMI), diabetes, hypertension, smoking and other factors were analyzed. An old age (OR = 1.090; 95% CI = 1.025-1.158; P = 0.006), a high BMI (OR = 1.509; 95% CI = 1.181-1.929; P = 0.001) and an increased post-surgery D-dimer (OR = 5.034; 95% CI = 2.091-12,117; P ≤ 0.001) value were significantly associated with an elevated DVT risk after knee arthroscopic PCL reconstruction. Increased age, BMI, and postoperative D-dimer were risk factors of DVT following knee arthroscopic PCL reconstruction in patients with only PCL injury.

Abstract Background To analyse the common risk factors of deep venous thrombosis (DVT) after knee arthroscopic posterior cruciate ligament (PCL) reconstruction in patients with PCL injury. Methods From August 2014 to December 2019, a total of 86 patients who had accepted knee arthroscopic PCL reconstruction underwent the color Doppler ultrasound of bilateral lower-extremities deep veins on 3 days postoperatively. Based on the inspection results, patients were divided into DVT group (9 males and 4 females, mean age 43.62 years) and non-DVT group (54 males and 19 females, mean age 33.96 years). The potential associations of DVT risk and age, gender, body mass index (BMI), diabetes, hypertension, smoking and other factors were analysed. Results High BMI and post-surgery D-dimer values were significantly associated with DVT risk. Conclusions Increased BMI and postoperative D-dimer levels are risk factors of DVT following knee arthroscopic PCL reconstruction in patients with PCL injury.

Objective: The objective of this work is to discuss and analyze the related factors of lower extremity fracture complicated by preoperative deep vein thrombosis (DVT). Methods: A total of 11,891 patients with closed fractures of lower extremities were selected. By analyzing each patient’s gender, age, presence or absence of diabetes and hypertension, preoperative plasma D-dimer level, and color Doppler ultrasound of the lower extremity vein, the pertinent factors of the patients with lower extremity fractures complicated by preoperative DVT were analyzed. Results: A total of 578 with preoperative DVT were detected, displaying a total incidence of 4.86%. All patients were categorized into either the DVT group or non-DVT group. The results demonstrate that there were statistically significant differences between the 2 groups in age, the presence of diabetes and hypertension, the fracture site, and the preoperative plasma D-dimer level ( P < 0.05). Logistic multivariate analysis revealed that age, the presence of diabetes, and the preoperative plasma D-dimer level of patients were independent risk factors for lower extremity fracture complicated by DVT. Conclusion: Age, the presence of diabetes, the fracture site, and increased D-dimer levels were found to be potential risk factors and indicators for preoperative DVT in patients with lower extremity fractures. In addition, the preoperative plasma D-dimer level has certain guiding significance for the prediction of venous thrombosis after lower extremity fracture, which is conducive to the early prediction and diagnosis of DVT, but it often must be followed with good clinic acumen and examinations.

BACKGROUND: Grade 3 posterior cruciate ligament (PCL) injury needs surgical intervention, but there is no consensus on the optimal technique in PCL reconstruction. The old technique always removes the remnant for good visualization of tunnel replacement. Recently, many studies proposed the concept of preservation of PCL remnant with achieve good visualization. AIM: The aim of the study is to evaluate PCL reconstruction with remnant preservation using the standard anterior and posteromedial portal at 2-year follow-up. METHODS: We conducted a cohort retrospective study between January 2013 and December 2015. In this study, 25 patients underwent PCL reconstruction using the standard anterior and posteromedial portal with remnant preservation. We used quadrupled hamstring autograft. The patients were assessed using the International Knee Documentation Committee (IKDC) score, Lysholm Knee Score, Modified Cincinnati Score, and knee society score (KSS) at pre-operative and 2-year post-operative. Range of motion (ROM) and complications were evaluated postoperatively. RESULTS: The mean diameter of the quadruple hamstring graft was 8 mm. Clinical outcomes enhanced significantly (p < 0.05). The average of Lysholm activity scale improved from 65.12 ± 10.48 to 94.96 ± 4.80. The IKDC score improved from 60.50 ± 15.10 to 95.60 ± 3.44. Modified Cincinnati score improved from 62. 28 ± 13.6 to 96.04 ± 1.62. The KSS also improved from 60.12 ± 18.01 to 94.88 ± 6.36. Twenty-two patients had 0–135° full ROM and three patients had 0–110° ROM. Two patients had surgical site infection but recovered with local debridement. CONCLUSION: PCL reconstruction using the standard anterior and posteromedial portal with remnant preservation at 2-year follow-up resulted in satisfactory clinical and functional outcomes.

Abstract Background: The factors leading to venous thromboembolism (VTE) have been known for a long time. Previous data has suggested a potential link between erythrocyte aggregation (EA) and deep vein thrombosis (DVT). Considering a relatively large number of patients who need total knee arthroplasty (TKA) surgery due to primary knee osteoarthritis (KOA), this study is tried to verify whether preoperative EA may have an effect on postoperative DVT after TKA in these patients.Methods: A total of 750 KOA patients accepted unilateral TKA were enrolled from March 2010 to May 2020. On the third day after surgery, they all accepted the color Doppler ultrasound examination of both legs for deep veins and were subsequently divided into DVT and non-DVT groups. We made a thorough analysis to demonstrate the specific association of EA exponent before TKA and DVT risk after TKA.Results: Low EA exponent was a significant risk factor for DVT in patients with primary KOA (p<0.05), especially in females after stratifying by gender (p<0.05). Conclusions: Our results suggested that low EA before TKA was substantially associated with a high post-surgery DVT risk in primary KOA patients. Timely and effective anticoagulant therapy for such patients was required.

Abstract Isolated and combined posterior cruciate ligament (PCL) injuries are associated with severe limitations in daily, professional, and sports activities as well as with devastating long-term effects for the knee joint. As the number of primary and recurrent PCL injuries increases, so does the body of literature, with high-quality evidence evolving in recent years. However, the debate about the ideal treatment approach such as; operative vs. non-operative; single-bundle vs. double-bundle reconstruction; transtibial vs. tibial inlay technique, continues. Ultimately, the goal in the treatment of PCL injuries is restoring native knee kinematics and preventing residual posterior and combined rotatory knee laxity through an individualized approach. Certain demographic, anatomical, and surgical risk factors for failures in operative treatment have been identified. Failures after PCL reconstruction are increasing, confronting the treating surgeon with challenges including the need for revision PCL reconstruction. Part 2 of the evidence-based update on the management of primary and recurrent PCL injuries will summarize the outcomes of operative and non-operative treatment including indications, surgical techniques, complications, and risk factors for recurrent PCL deficiency. This paper aims to support surgeons in decision-making for the treatment of PCL injuries by systematically evaluating underlying risk factors, thus preventing postoperative complications and recurrent knee laxity.

BackgroundAnatomic studies of the paediatric posterior cruciate ligament (PCL) demonstrate that the tibial attachment spans the epiphysis, physis and metaphysis. To better reproduce the anatomy of the PCL and avoid direct physeal injury, a double-bundle PCL reconstruction technique that includes both an all-epiphysial and an all-metaphyseal tibial tunnel has been proposed. The purpose of this study was to evaluate tibial tunnel placement in a paediatric double-bundle PCL reconstruction technique that avoids direct physeal injury using a 3-D computer model.MethodsTen skeletally immature cadaveric knee specimens (ages 5–11) were used to create 3-D model reconstructions from CT scans. All-metaphyseal and all-epiphysial tibial tunnels were simulated with the goal of maintaining adequate spacing (≥2 mm) between the tibial physis and tunnels to avoid injury. The all-metaphyseal tunnel, simulated at sizes of 5, 6 and 7 mm, entered anteriorly, below the tibial tubercle (apophysis) and exited posteriorly in the metaphyseal PCL footprint, distal to the proximal tibial physis. Four-millimetre all-epiphysial proximal tibial tunnels were simulated to enter the epiphysis anteromedially and exit posteriorly at the central epiphysial region of the PCL footprint, proximal to the physis. The distance was measured from the all-metaphyseal tunnels to the physis posteriorly and from the all-epiphysial tunnels to the physis, both anteriorly and posteriorly.ResultsIn all specimens, the 4 mm all-epiphysial tunnel and the 5, 6 and 7 mm all-metaphyseal tunnels maintained adequate spacing, ≥2 mm from the physis. In the specimens aged 5–7 years, the 5, 6 and 7 mm all-metaphyseal tunnels measured a mean distance of 3.5, 2.8 and 2.5 mm from the physis, respectively. In the specimens aged 8–11 years, the 5, 6 and 7 mm all-metaphyseal tunnels measured a mean distance of 3.4, 2.9 and 2.6 mm from the physis. In the specimens aged 5–7 years, the all-epiphysial tunnel measured a mean of 2.1 mm to the physis anteriorly and a mean of 2.8 mm posteriorly. In the specimens aged 8–11 years, the all-epiphysial tunnel measured a mean of 2.2 mm to the physis anteriorly and 2.4 mm posteriorly.ConclusionThese computer-aided 3-D models of paediatric knees illustrate that 5, 6 and 7 mm all-metaphyseal tunnels as well as 4 mm all-epiphysial tunnels can be placed without direct injury to the proximal tibial physis. The margin of error for direct physeal injury is small, especially for the all-epiphysial tunnel. Further, the all-epiphysial tunnel, while reproducing the anatomy of the PCL epiphysial attachment, may also produce a more extreme ‘killer turn’ of the graft. Modifications to the all-epiphysial tunnel may be considered to reduce the impact of the high ‘killer turn’ angle on the tibia.Level of evidenceIV.
