前交叉韧带重建术止点定位的临床研究   总被引:2,自引:0,他引:2  
[目的]通过比较不同临床结果下前交叉韧带重建术骨隧道止点位置的差异,探讨理想骨隧道的影像学位置。[方法]选择55例关节镜下前交叉韧带重建术病例,对过伸位X线侧位片测量并分别计算股骨、胫骨止点及Blumensaat线的胫骨平台投影点相对位置。根据临床结果不同分两组对上述资料分析影像表现差别。[结果]股骨侧止点位置在不同临床结果的两组间有显著性差异,胫骨止点位置和Blumensaat线投影点位置组间无差异性。胫骨止点均位于Blumensaat线投影点之后。[结论]股骨侧止点位置偏前临床效果较差,大致位于Blumensaat线距股骨外侧髁前缘交点的65%-69%之间。胫骨侧止点在伸直位Blumensaat线胫骨投影点之后,大致位于胫骨平台前后直径距前缘38%-41%之间。术前进行患膝关节的过伸位X线片检查,并测量Blumensaat线的胫骨投影位置,有助于为术前胫骨止点定位提供参考。  相似文献

Purpose

The aim of this study was to compare the outcomes between anteromedial (AM) and transtibial (TT) femoral tunnel positioning techniques for the reconstruction of chronic anterior cruciate ligament (ACL) rupture.

Materials and methods

It is a randomized prospective study of 106 patients who underwent ACL reconstruction because of a chronic ACL rupture (55 AMT, 51 TT). Minimum follow-up was 2 years. Demographic, clinical and radiological data, including MRI grafts’ anatomy and biomechanics intraoperative navigation system evaluation, were analyzed. Also, International Knee Documentation Committee score, Tegner Knee score, Lysholm Knee Score, Short-Form Health Survey and 4-point Likert Scale were evaluated.

Results

The AM technique achieves a more anatomic graft than TT technique in both sagittal and coronal plane (6° approximately). Immediate postoperative biomechanical evaluation of the graft showed both techniques significantly improved translational and rotational laxity (p = 0.000). AMT showed superiority only in controlling internal rotation (p = 0.016). Both techniques reported significant improvement in all evaluated score scales, without differences between techniques. Independently of the femoral tunnel positioning technique, patients with cartilage lesion had worse clinical outcomes.

Conclusions

Our findings suggest that AMT achieves a more anatomical and biomechanically accurate graft allowing better control over internal rotation laxity; however, this does not lead to better clinical outcomes if we compare with TT in the reconstruction of chronic ACL rupture. Patients with chronic ACL rupture and cartilage lesion had worse clinical outcomes, independently the femoral tunnel positioning technique.

Background

Several studies have recently shown better restoration of normal knee kinematics and improvement of rotator knee stability after reconstruction with higher femoral tunnel obliquity. The aim of this study is to evaluate tunnel obliquity, length, and posterior wall blowout in single-bundle anterior cruciate ligament (ACL) reconstruction, comparing the transtibial (TT) technique and the out–in (OI) technique.

Materials and methods

Forty consecutive patients operated on for ACL reconstruction with hamstrings were randomly divided into two groups: group A underwent a TT technique, while group B underwent an OI technique. At mean follow-up of 10 months, clinical results and obliquity, length, and posterior wall blowout of femoral tunnels in sagittal and coronal planes using computed tomography (CT) scan were assessed.

Results

In sagittal plane, femoral tunnel obliquity was 38.6 ± 10.2° in group A and 36.6 ± 11.8° in group B (p = 0.63). In coronal plane, femoral tunnel obliquity was 57.8 ± 5.8° in group A and 35.8 ± 8.2° in group B (p = 0.009). Mean tunnel length was 40.3 ± 1.2 mm in group A and 32.9 ± 2.3 mm in group B (p = 0.01). No cases of posterior wall compromise were observed in any patient of either group. Clinical results were not significantly different between the two groups.

Conclusions

The OI technique provides greater obliquity of the femoral tunnel in coronal plane, along with satisfactory length of the tunnel and lack of posterior wall compromise.

BackgroundProper positioning of osseous tunnels during single bundle arthroscopic ACL reconstruction, which gives reproducibly good clinical outcome, is a matter of concern. Little evidence is there correlating tunnel position in arthroscopic ACL reconstruction with their clinical outcome in Indian population. Our aim in this study was to examine if the radiological tunnel-positions were significantly associated to the clinical outcomes.MethodsACL reconstruction was performed in 147 young patients with an isolated ACL tear. They were followed up prospectively for the next two years. Clinical assessment of each patient was done using the International Knee Documentation Committee (IKDC) evaluation form before surgery and at two years later the surgery. At the same time, the radiological assessment was done on standard digital radiographs.ResultsConsidering the anterior and posterior-most points on the Blumensaat's line as 0% and 100% respectively the average position of the femoral tunnel was at 84.8%. Similarly, the tibial tunnel was at 46.8% along the tibial plateau. On the coronal plane the average position of the tibial tunnel was at 45.6% point along the tibial plateau (measured from the medial-most point towards laterally). The mean position of the femoral tunnel in the coronal plane was at 43.2% along the broadest part of the distal femur (measured from the lateral extent). The average inclination angle of the graft measured 19.6° (along the coronal plane).ConclusionIdeal clinical outcome was significantly associated with the placement of the femoral tunnel along the sagittal plane. Placement of the femoral tunnel should not be beyond the 85% mark along the Blumensaat's line from the anterior-most point. No correlation was established between clinical results and any of the remaining radiological parameters described above.  相似文献

BackgroundThe femoral anterior tangent (FAT) line refers to a line parallel to the anterior surface of the distal femur in the axial plane. This study aimed to evaluate the effectiveness of a new operation support system which uses the FAT line to set the femoral component rotational alignment in total knee arthroplasty (TKA).MethodsA total of 170 consecutive knees in 139 patients undergoing primary TKA with the JIGEN (Jig Engaged Three-dimensional (3D) Pre-Operative Planning Software for TKA) operation support system was examined. The JIGEN system creates 3D models of bones using computed tomography data, allowing for surgical simulations such as positioning of implants while calculating positions of the intramedullary alignment rod (IM rod) and surgical jig. We retrospectively analyzed the FAT line angle relative to the surgical epicondylar axis (SEA) on the axis plane perpendicular to the IM rod and evaluated the accuracy of the femoral component alignment after TKA with the 3D measurement system.ResultsThe FAT line was 9.6° ± 3.7° (range, 1.4°–20.4°) internally rotated relative to the SEA. The average absolute error was 1.4° ± 1.1° in the coronal plane, 2.0° ± 1.5° in the sagittal plane, and 1.6° ± 1.3° in the axial plane. The femoral component outliers (i.e., >3° away from the goal alignment) were 7.7% in the coronal plane, 20.6% in the sagittal plane, and 10.3% in the axial plane.ConclusionsOur findings suggest that the FAT line is a reliable and reproducibly identifiable axis for the accurate determination of proper rotational alignment in TKA. An operation support system which uses the FAT line for determining intraoperative femoral component rotation can effectively achieve highly accurate positioning of the femoral component in TKA.  相似文献

Background

Total knee arthroplasty (TKA) in patients with post-traumatic extra-articular deformity (EAD) is difficult to manage using conventional instrumentation techniques. In this study, we evaluate whether accelerometer navigation system can be a valuable option to make accurate bone resections and restore the neutral mechanical axis in complex TKA patients with EAD.

Methods

From May 2015 to June 2017, 18 consecutive TKA were performed in 18 patients with knee osteoarthritis with associated EAD. An accelerometer-based navigation system was used to guide tibial and femoral resection in the coronal and sagittal plane. Postoperative lower limb alignment in coronal plane and component position in coronal and sagittal plane was measured through full-leg weight-bearing X-ray. Clinical score were recorded using the Knee Society Score at the final follow-up.

Results

The mean hip-knee-ankle angle was 0.9° ± 1.4° varus alignment. The coronal alignment of the femoral component was 89.2° ± 1.9°, and the coronal alignment of the tibial component was 89.4° ± 2.1°. The sagittal alignment of the femoral component was 93.2°± 1.9°, and the sagittal alignment of the tibial component was 84.4° ± 3.1°. At the final follow-up, the Knee Society Score was 89 points (range, 82-100), and the functional score was 86.7 points (range, 60-100). No intraoperative and postoperative surgical complications were reported using this technology.

Conclusion

Accelerometer-based navigation is accurate in achieving neutral mechanical alignment and optimal implant position after TKA in patients with EAD. This system should be considered a valuable option to the more complex technique of computer navigation or robotic surgery.  相似文献

IntroductionBicondylar tibial plateau fractures with meta-diaphyseal comminution commonly have a compromised soft tissue envelope. Combined plate-nail fixation is an emerging technique that utilizes a limited anterolateral approach for plate application and percutaneous incisions for placement of an intramedullary nail. This technique alleviates the need for a separate medial approach to the proximal tibia. We report a series of patients treated with this approach and outline the steps for implementation.MethodsWe performed a retrospective review of 18 consecutive patients treated with combination lateral locked plating and intramedullary nailing at a single academic institution from 2016 to 2019. Of these, 16 patients met inclusion criteria and were included in this study. All patients had AO/OTA type 41C2/C3 fractures. Primary outcomes included coronal plane and sagittal plane alignment at latest follow up, rate of articular subsidence at latest follow up, and rate of postoperative infection.ResultsOf the 16 patients included, average followup was 8.2 months (range 0.1-29.7 months). At latest follow-up, average coronal alignment ranged from 0.8±1.2 degrees of varus (maximum 4.0 degrees) to 1.4±1.7 degrees of valgus (maximum 4.0 degrees). Average sagittal alignment ranged from 0.8±1.1 degrees of procurvatum (maximum 3.0 degrees) to 0.6±1.2 degrees of recurvatum (maximum 4.0 degrees). There was no radiographic evidence of articular subsidence at latest follow up for any patient. One patient (5.9%) presented at 141 days postoperatively with a draining wound and infection.ConclusionsCombination plate-nail fixation is a viable option for treating patients with select bicondylar tibial plateau fractures with meta-diaphyseal comminution. This case series with short-term followup demonstrates acceptable radiographic and clinical outcomes, as well as rates of postoperative infection and implant removal similar to those currently reported in the literature for other techniques used to treat these fractures.  相似文献
