Abstract Speed skating is a cyclic sport which involves the hip abductor muscles, impelling the participant forwards, and adductor muscles, in the recovery phase and decelerating the abduction movement eccentrically. This paper has the objective of describing and comparing the abduction/adduction torque-angle curves of speed skating athletes (N=10) with a group of non-practitioners young participants (N=10). Both groups presented similar peak torques and electromyography patterns for tensor fascia lata, gluteus medius, long adductor and adductor magnus. However, athletes showed higher torque-angle curve integral and abduction and adduction peak torques at different hip angles than the control group. These findings suggest an adaptation of their musculotendon actuators and a better capacity to generate mechanical work and power during a propulsion-recovery cycle.

Background: Hip abductor tendon repair has demonstrated encouraging outcomes. The influence of fatty infiltration (FI) on outcome has not been explored. Purpose: To investigate the association between preoperative hip abductor FI and clinical outcome after hip abductor tendon repair. Study Design: Case series; Level of evidence, 4. Methods: A total of 84 women underwent hip abductor tendon repair. The mean age was 64.6 years (range, 43-84 years); body mass index, 27.7 (range, 20.0-40.2); and duration of symptoms, 3.4 years (range, 6 months–20 years). The 6-minute walk test, isometric hip abduction strength assessment, and patient-reported outcome measures, including the Harris Hip Score and Oxford Hip Score, were completed presurgery and 2 years after surgery. Patient satisfaction and perceived improvement were assessed 2 years after surgery. All patients underwent preoperative magnetic resonance imaging on the affected hip, and the Goutallier system was used to grade the degree of FI in the anterior, middle, and posterior thirds of the gluteus medius and minimus on a 0-4 ordinal scale. A single FI score for the gluteus medius and minimus was calculated, as was a combined FI score. Results: All clinical scores significantly improved over time ( P < .001). Preoperatively, FI was more severe in the gluteus minimus, with the most severe FI (grades 2-4) demonstrated in the middle (n = 56, 66.7%) and anterior (n = 17, 20.2%) portions of the gluteus minimus and the middle (n = 27, 32.1%) and anterior (n = 12, 14.3%) portions of the gluteus medius. Older age was associated with greater FI (combined FI score: r = 0.529, P < .001), although duration of symptoms ( r = 0.035, P = .753) and body mass index ( r = 0.089, P = .464) were not. Greater FI was associated with less improvement in hip strength of the unaffected leg (coefficient, –1.6, 95% CI: −2.8 to −0.4), although no other significant associations were observed between FI and pre- or postoperative clinical scores. Conclusion: Preoperative FI was not associated with pertinent parameters of patient outcome after hip abductor tendon repair, including pain, symptoms, functional capacity, perceived improvement, and satisfaction. Based on these outcomes, surgical repair may be considered in the presence of more severe FI.

ABSTRACT Hip abductor tendon tears of the gluteus medius and minimus are becoming a well-recognized source of pain and dysfunction, primarily in middle-age females. Like the rotator cuff, fatty infiltration (FI) can occur after tearing of these tendons. While the association of TFL hypertrophy after abductor tendon tears has been established, its association with FI has not been well studied. Our hypothesis is that hypertrophy of the TFL will be associated with FI of the abductors. All patients &gt;18 years old undergoing primary surgical repair for a confirmed tears on MRI, without a history of prior hip surgery or osteoarthritis, were included. The following measurements were obtained from MRI: TFL cross-sectional area, TFL:sartorius volume ratio, and modified Goutallier grade of gluteus medius and minimus. Seventy patients met inclusion criteria and were divided in two groups, those with (n = 28) and those without FI (n = 42) of the abductors. The FI group was on average older (65 versus 58 years, P &lt; 0.00016). TFL hypertrophy and TFL:sartorius volume ratio were significantly associated with FI (P= 0.00069). Following abductor tendon tear and subsequent FI, there exists significant TFL hypertrophy in patients without a prior history of hip surgery in our patient cohort.

Abstract BackgroundThe hip abductors are crucial in maintaining pelvic stability. Tears in these tendons are common and often debilitating. There is uncertainty regarding both the histological and macroscopic features of hip abductor tears. This study aims to clarify both the macroscopic and microscopic features of the tendon and enthesis in hip abductor tendon tears.MethodsThirty-six cadavers with an average age of 81 were dissected, and the hip abductor mechanisms removed en-bloc. The presence, location and size of the tears were recorded and analysed. The samples were processed into histological blocks and viewed using both transmitted and polarised light. Tendon histology was graded using the modified Movin’s score in three sections (deep, middle and superficial layers) and the enthesis graded separately using 5-point criteria. Analysis of variance was used to confirm histological features associated with tears.ResultsTears were found in 24 of 36 samples (67%). The most common finding was an isolated tear in the gluteus minimus (46%), followed by concurrent gluteus medius and gluteus minimus tears (33%). Histology revealed significantly more degeneration in both the tendon (p = 0.0005) and enthesis (p = 0.0011) when tears were present. Furthermore, these changes were concentrated in the deeper layers of the tendon (p = 0.0002) and enthesis (p = 0.003).ConclusionThis study demonstrated degeneration as the primary pathology underlying hip abductor tendon tears. Degenerative changes occur in both the tendon and enthesis, with the deeper layers predominantly affected. These findings are important for guiding surgical repair techniques and to aid the development of novel materials and biologics.
