膝关节X线对外侧髌股挤压综合征的评估

目的评估外侧髌股挤压综合征患者膝关节X线片,明确其诊断意义。方法对实验组和对照组摄膝关节X线片,观察膝关节骨质结构情况,测量滑车角、吻合角及髌股指数,两组间进行比较。结果实验组滑车角（132.44±10.21）°,吻合角（7.67±5.81）°,髌股指数（2.49±1.40）,对照组滑车角（136.8±4.87）°,吻合角（-2.2±-2.71）°,髌股指数（1.25±0.15）。两组间滑车角差异无统计学意义（t=0.887,P〉0.05）;两组间吻合角和髌股指数差异均有统计学意义（吻合角t=4.318,P〈0.05;髌股指数t=2.633,P〈0.05）。两组间髌股关节软骨下骨质硬化,实验组9膝,对照组2膝,差异有统计学意义（2=12.169,P〈0.01）;两组间髌股关节外侧边缘骨赘增生,实验组13膝,对照组3膝,差异有统计学意义（2=12.60,P〈0.01）。结论膝关节X线片是诊断外侧髌股挤压综合征最基本的手段,其中髌股指数应用方便。

In‐vivo patellar tracking in individuals with patellofemoral pain and healthy individuals

Understanding of the exact cause of patellofemoral pain has been limited by methodological challenges to evaluate in‐vivo joint motion. This study compared six degree‐of‐freedom patellar motion during a dynamic lunge task between individuals with patellofemoral pain and healthy individuals. Knee joints of eight females with patellofemoral pain and ten healthy females were imaged using a CT scanner in supine lying position, then by a dual‐orthogonal fluoroscope while they performed a lunge. To quantify patellar motion, the three‐dimensional models of the knee bones, reconstructed from CT scans, were registered on the fluoroscopy images using the Fluomotion registration software. At full knee extension, the patella was in a significantly laterally tilted (PFP: 11.77° ± 7.58° vs. healthy: 0.86° ± 4.90°; p = 0.002) and superiorly shifted (PFP: 17.49 ± 8.44 mm vs. healthy: 9.47 ± 6.16 mm, p = 0. 033) position in the patellofemoral pain group compared with the healthy group. There were also significant differences between the groups for patellar tilt at 45°, 60°, and 75° of knee flexion, and for superior‐inferior shift of the patella at 30° flexion (p ≤ 0.031). In the non‐weight‐bearing knee extended position, the patella was in a significantly laterally tilted position in the patellofemoral pain group (7.44° ± 6.53°) compared with the healthy group (0.71° ± 4.99°). These findings suggest the critical role of passive and active patellar stabilizers as potential causative factors for patellar malalignment/maltracking. Future studies should investigate the associations between patellar kinematics with joint morphology, muscle activity, and tendon function in a same sample for a thorough understanding of the causes of patellofemoral pain. © 2018 Orthopaedic Research Society.

The effect of femoral component rotation on the extensor retinaculum of the knee

Malrotation of the femoral component may cause patellofemoral complications after total knee replacement (TKR). We hypothesized that femoral component malrotation would cause excessive lengthening of the retinacula. Retinacular length changes were measured by threading fine sutures along them and attaching these to the patella and to displacement transducers. The knee post‐TKR was flexed‐extended while the quadriceps were tensed, then the measurements repeated after rotating the femoral component 5° internally and then 5° externally. Internal rotation shortened the medial patellofemoral ligament (MPFL) significantly from 100° to 0° extension. External rotation lengthened the MPFL significantly from 90° to 0° extension. The transverse fibers of the lateral retinaculum showed no significant differences. The MPFL attaches directly from bone to bone, so it was lengthened directly by movement of the trochlea and patella, whereas the deep transverse fibers of the lateral retinaculum attach to the mobile iliotibial tract, so they were not lengthened directly. © 2010 Orthopaedic Research Society.

Computational approach to correcting joint instability in patients with recurrent patellar dislocation

Patellar dislocation is a debilitating injury common in active adolescents and young adults. Conservative treatment after initial dislocation is often recommended, but almost half of these patients continue to suffer from recurrent dislocation. The objective of this study was to compare preoperative patellofemoral joint stability with stability after a series of simulated procedures, including restorative surgery to correct to pre-injury state, generic tibial tubercle osteotomy, patient-specific reconstructive surgery to correct anatomic abnormality, less invasive patient-specific surgery, and equivalent healthy controls. Three-dimensional, subject-specific finite element models of the patellofemoral joint were developed for 28 patients with recurrent patellar dislocation. A 50 N lateral load was applied to the patella to assess the lateral stability of the patellofemoral joint at 10° intervals from 0° to 40° flexion. Medial patellofemoral ligament reconstruction, along with reconstructive procedures to correct anatomic abnormality were simulated. Of all the simulations performed, the healthy equivalent control models showed the least patellar internal–external rotation, medial–lateral translation, and medial patellofemoral ligament restraining load during lateral loading tests. Isolated restorative medial patellofemoral ligament reconstruction was the surgery that resulted in the most patellar internal–external rotation, medial–lateral translation, and medial patellofemoral ligament reaction force across all flexion angles. Patient-specific reconstruction to correct anatomic abnormality was the only surgical group to have non-significantly different results compared with the healthy equivalent control group across all joint stability metrics evaluated. Statement of clinical significance: This study suggests patient-specific reconstructive surgery that corrects underlying anatomic abnormalities best reproduces the joint stability of an equivalent healthy control when compared with the pre-injury state, generic tibial tubercle osteotomy, and less invasive patient-specific surgery. © 2019 Orthopaedic Research Society.

Femoroacetabular impingement and risk factors: a study of 50 cases

Objective: To study the asphericity of the femoral head in femoroacetabular impingement using the radiological indices alpha angle and triangular index, and correlation with risk factors. Methods: The study was conducted retrospectively from January 2008 to June 2010 on 50 consecutive patients with suspected cam type femoroacetabular impingement of the hip who reported to the orthopaedics outpatients department of the Postgraduate Institute of Medical Education and Research. Ten controls were also used in the study. Radiographs of the affected hip were taken and then the alpha angle and triangular index were measured and correlated with various risk factors. Results: In the anteroposterior view the alpha angle range was from 55° to 106° for the cases and from 54° to 70° for the controls. In the lateral view the range was from 62° to 104° for the cases and from 54° to 62° for the controls. The mean alpha angle in the anteroposterior view was measured as 75°± 10° in the cases and 61°± 6° in the controls, and the mean in the lateral view was 74°± 8° in the cases and 58°± 6° for the controls. The triangular index range in the radiographs was from 1 to 7 in the cases and from 0 to 1 for the controls. The mean triangular index in the radiographs was 2.9 ± 1.2 for the cases and 0.2 ± 0.4 for the controls. Conclusion: There was no significant correlation between the age and gender of the patient and the femoroacetabular impingement. However, there was significant correlation between the body mass index of the patient and the femoroacetabular impingement.

An investigation into the effect of number of trials during proprioceptive testing in patients with patellofemoral pain syndrome

The purpose of this study was to investigate the effect of increasing the number of test trials in the assessment of knee joint position sense, in a group of patellofemoral patients, and second, to investigate the effects of joint angle and type of test. Thirty‐two patients with a diagnosis of patellofemoral pain syndrome were admitted to this study. Knee joint position sense was measured by performing an ipsilateral matching activity at target angles of 20° and 60° using two techniques; Passive Angle Reproduction (PAR), and Active Angle Reproduction (AAR). The results show that five repetitions are required for AAR and six for PAR. A two‐way repeated‐measures ANOVA showed that there was no significant difference (p = 0.559) in the accuracy of angle reproduction for the two angles (60° and 20°); however, there was a significant difference (p = 0.001) between the two types of test (AAR and PAR). The results of this study have implications for clinicians and researchers who examine knee joint proprioception as part of functional assessment in a variety of knee joint pathologies including PFPS. A “quick” one‐off assessment of knee joint position sense may give erroneous data; subjects need to have several trials before a true picture of their proprioceptive status emerges. Type of testing performed, active or passive, is also important, although the angle of testing may not be relevant. © 2006 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.
