Dynamic Valgus

Individuals with anterior cruciate ligament reconstruction (ACLR) are at a higher risk for subsequent anterior cruciate ligament (ACL) tears. Risk factors for ACL injuries likely involve a combination of anatomical, biomechanical, and neuromuscular factors. Dynamic knee valgus has been indicated as a possible biomechanical factor for future ACL injuries. Given that knee valgus is often accompanied by contralateral pelvic drop during single-leg activities, a dynamic valgus index (DVI) that quantifies combined kinematics of the knee and hip in the frontal plane has recently been developed. As the premise of asymmetrical DVI between limbs in the ACLR population has not been examined, this cross-sectional study was conducted with the aim to compare DVI between individuals with ACLR and healthy controls. Videos were taken for 12 participants with ACLR and 20 healthy controls when they performed single-leg hopping. One-way ANOVA revealed a higher DVI in the injured limb of the ACLR group when compared to their non-injured limb and to the healthy limb of the control group. As our data showed increased DVI in the injured limb of the ACLR group, the DVI approach accounting for hip and knee kinematics may be used to identify frontal plane movement deficits during single-leg hopping in individuals with ACLR.

Kết luận: nội soi tái tạo DCCT với kỹ thuật "tất cả bên trong" là phương pháp ít xâm lấn, an toàn, đạt hiệu quả cao và giúp người bệnh đạt được chức năng khớp gối hoàn hảo, đặc biệt ở những trường hợp có nhu cầu chơi thể thao cao. Abstract Introduction: To evaluate the results and to share the experience of arthroscopic all-inside ACL (Anterior Cruciate Ligament) reconstruction. Material and Methods: 700 patients who had ACL injuries were arthroscopically reconstructed with all-inside techniquein Viet Duc University Hospital from May, 2015. Results: after surgery, the good outcome rates and excellent were 97,6%, average Lysholm scores were 96,2 (91-100 points), compared to pre-operation is 57,2 (47-61 points), most of the patients after surgery had Lachman sign and negative axial shaft movement. Conclusion: The arthroscopic reconstruction of the ACL with all-inside technique was a less invasive technique, safe, highly effective and helps patients achieve the function of perfect knee joint, especially in cases of requirement for high sports.

Meniscal tears are commonly associated with anterior cruciate ligament (ACL) injuries. A deficient medial meniscus results in knee instability and could lead to higher stress forces on the ACL reconstruction.Comparison of results in meniscectomy and meniscal repairs revealed worse clinical outcomes in meniscectomy, but higher re-operation rates in meniscal repairs. Our aim was to review the results of ACL reconstruction associated with meniscectomy or meniscal repair.

Abstract Purpose We modified the hamstring tendon graft into the hamstring-bone composite graft in double-bundle anterior cruciate ligament reconstruction for anterior cruciate ligament (ACL) injuries. Here, we evaluated the technique's effectiveness by investigating the clinical results in restoring the stability and function of the knee joint. Methods We reviewed 42 patients who underwent anterior cruciate ligament reconstruction (ACLR) with the hamstring-bone graft for ACL injuries from January 2013 to April 2015, with an average follow-up of 66.6 months. The objective evaluations (KT-1000, Lachman test and pivot-shift test) and the subjective evaluations (International Knee Documentation Committee (IKDC) scores, Lysholm scores, and Tegner scores) were performed preoperatively and postoperatively. Results Forty-one of 42 patients were negative in the Lachman test and forty of 42 patients were negative in the pivot-shift test after the operation at the final follow-up time. The IKDC, Lysholm, and Tegner scores improved significantly from 56.24±9.28 to 85.33±3.37, from 62.00±11.09 to 90.43±3.71，and from 2.3±0.87 to 6.5±0.67 at the final follow-up. Conclusion Double-bundle anatomic ACLR with a hamstring-bone composite graft can restore the anteroposterior and rotational stability for ACL injuries. The modified technique can provide excellent clinical outcomes with a long-term follow-up.

Background: The limb symmetry index may overestimate the recovery of quadriceps muscle strength after anterior cruciate ligament reconstruction. Comparison of individuals who have had anterior cruciate ligament reconstruction with age-, sex-, and activity-matched individuals might be more appropriate to guide rehabilitation interventions. Purpose: To compare the quadriceps strength between the injured limb of people with anterior cruciate ligament reconstruction and the limb of an age-, sex-, and activity-matched control group. Study Design: Systematic review; Level of evidence, 3. Methods: MEDLINE, CINAHL, EMBASE, SCOPUS, and SPORTDiscus were searched between inception and April 2019. Studies were included if they reported the peak quadriceps strength for persons with anterior cruciate ligament reconstruction and age-, sex-, and activity-matched control groups measured using isometric or isokinetic dynamometry. Risk of bias was assessed, and meta-analyses and metaregression (for effect of time since surgery) were performed. Results: A total of 2759 studies were identified and 21 were included for analyses. Quadriceps strength was lower in the limbs with anterior cruciate ligament reconstruction compared with the limb from matched controls within 6 months of anterior cruciate ligament reconstruction (standardized mean difference [SMD], –1.42; 95% CI, –1.62 to –1.23), 6 to 18 months after anterior cruciate ligament reconstruction (SMD, –0.92; 95% CI, –1.18 to –0.66), and >18 to 48 months after anterior cruciate ligament reconstruction (SMD, –0.38; 95% CI, –0.79 to 0.03). Results of the metaregression were significant, with the difference between anterior cruciate ligament reconstruction and matched controls decreasing with time since surgery ( P < .001). Conclusion: In people with anterior cruciate ligament reconstruction, the injured limb had lower quadriceps strength compared with the limb of age-, sex-, and activity-matched controls up to 4 years after surgery. Clinicians should consider comparison with matched cohorts for return to sports decision making.
