“…However, we found that most of the reports on arthroscopic resection of extra-articular osteochondroma are case reports, and there are few comparatively systematic follow-up and analysis studies, let alone multi-dimensional functional evaluation on patients. The author's department focuses on sports medicine clinical and scientific research and has tried the application of arthroscopy in extra-articular osteochondroma for years [10,29]. Our surgical approach is to create two arthroscopic portals with an interval of 3 cm directly on the surface of the tumor, without entering the joint, avoiding damaging important structures.…”

Objective: The aim of this study was to investigate clinical outcomes of arthroscopic resection of extraarticular knee osteochondroma. Methods: A retrospective analysis was performed in 74 patients with extra-articular knee osteochondroma treated by arthroscopic resection between August 2011 and August 2021, including 43 males and 31 females. Overall, 26 Distal femur cases and 48 proximal tibia cases were involved, with an average age of 31.7 ± 11.3 (11–57) years. Preoperative routine knee X-ray, CT, and MRI were performed before the operation. The Lysholm knee score, International Knee Documentation Committee (IKDC) score, Tegner knee motor function score, and visual analogue scale (VAS) were used to evaluate symptoms and functions before surgery and 3, 6, 12, and ≥24 months after surgery. Results: The average course of disease was (7.9 ± 3.7) months (range, 3–14 months) in 74 patients. The average follow-up was (22.6 ± 6.4) months (range, 10–37 months). There were no cases of vascular or nerve injury or wound infection. Compared with the preoperative function, the average scores of VAS, Lysholm, IKDC, and Tegner joint motor function decreased or increased significantly compared with the last follow-up (3.6 ± 1.1 vs. 0.1 ± 0.02, 44.5 ± 2.3 vs. 91.3 ± 4.9, 53.7 ± 2.6 vs. 94.2 ± 5.1, 4.6 ± 1.2 vs. 9.4 ± 1.4, p < 0.001). There was no recurrence or metastasis during the follow up. Conclusions: With the advantages of less trauma, high precision, less pain, and rapid recovery, arthroscopic resection of extra-articular knee osteochondroma can significantly improve the function of knee. It can be gradually extended to the treatment of other benign bone tumors.

“…These involved muscles may be found with muscle fibers degeneration and necrosis, fibrous connective tissue proliferation, and myofascial and fascia hypertrophy, leading to a sequence of secondary pathological changes, such as the hip muscles out-of-balance, which may cause abduction and external rotation deformities of the hip joint, pelvic tilt, and acetabular dysplasia.

Are “normal hips” being labeled as femoroacetabular impingement due to EE angle?

Gluteal muscle contracture (GMC) is a clinical syndrome characterized by gait abnormality and limb dysfunction, as well as secondary deformities of pelvis and femur. Femoroacetabular impingement (FAI) typically could be diagnosed on the basis of computed tomography (CT) such as the equatorial-edge angle (EE angle), but it did not work well in GMC patients. In this study, we retrospected all image data and found small EE angles in GMCs, which meant retroverted acetabulum; however, none of them showed no symptoms and signs of FAI. Therefore, we had reasons to think that, some normal hips with unbalanced hip myodynamia as same as GMCs, may be incorrectly diagnosed as FAI through measuring EE angle only.In consequence, the paper was designed to assess the use of the EE angle in the assessment of FAI in the diagnosis, as described by Werner.Twenty-three patients (46 hips) were collected and calculated with the “equatorial-edge angle” (EE angle) by CT scans. All of them were excluded from FAI.Review of the hips showed a mean EE angle was 12.93°, with a minimum of -3.42° and a maximum of 24.08°. The mean value for males and females were 13.52° and 12.40°, respectively, without statistical significance, although the mean value of left hips and right sides reached 13.32° and 12.54° individually, not having statistical differences neither. There were not any symptoms or signs of FAI in all patients. Thus, the reduced EE angle could suggest the local excessive coverage of the femoral head by the anterior acetabular edge, but might not be a reasonably good predictor of FAI.GMC patient's acetabular deformity mainly manifests as increased retroversion, which may be the anatomical basis for FAI and lead to high risks of the acetabular impingement. However, all patients in this study showed no symptoms and signs of FAI, suggesting that the measurement of EE angle can only be applied to assessing those people with normal hip myodynamia, and the bone deformity and the muscular disorder should be both considered in the diagnosis of FAI.

“…According to previous studies, GMC mostly occurs in the patients with a history of repeated intramuscular injection in the period of infant and preschool age [3], with an incidence rate of 0.7-10.1% [4][5][6]. Notably, patients with GMC are more common in China compared with other countries [7]. After muscles of buttock contracture, the elasticity and length of the muscle will decrease to form ber contracture band.…”

Objective In the clinic, gluteus muscle contracture (GMC) is found to cause pelvic structural changes, including acetabular retroversion (AR). However, its incidence has not been reported. This study aimed to explore the anteroposterior pelvic radiographs of GMC patients to identify the prevalence of AR. Methods The imaging characteristics of anteroposterior pelvic radiographs on 100 cases of GMC and 100 healthy people were analyzed. GMC was diagnosed by ‘iliac hyperdense line’(IHDL), while ‘prominence of the ischial spine’ (PRIS) or cross-over sign’ (COS) were used to define AR. Results ‘iliac hyperdense line’ was only observed in GMC patients (92%). There were 80 cases that showed PRIS in the GMC group, but only 19 in the control group. Similarly, the incidence of COS was 76% in patients and 5% in normal people. All the differences between the two groups of these indicators were statistically significant (P < 0.001). Furthermore, a statistical correlation was confirmed between PRIS and COS when they were positive in GMC patients. Conclusion AR showed a high incidence in patients with GMC based on PRIS and COS.
