Background: Endoscopic surgical repair has become a common procedure for treating patients with hip abductor tendon tears. Considering that retear rates are high after the repair of gluteus medius and minimus tendons, exploring alternative strategies to enhance structural healing is important. Purpose/Hypothesis: The purpose of this study was to evaluate the effect of adding microfracture to single-row repair (SR) on outcomes after the surgical repair of gluteus medius and minimus tendons and compare with SR and double-row repair (DR) without microfracture. We hypothesized that microfracture of the trochanteric footprint with SR would lead to superior clinical outcomes and lower clinically evident retear rates compared with SR and DR without the addition of microfracture. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 50 patients who underwent primary arthroscopic repair of hip gluteus medius and minimus tendon tears were investigated. Patients were divided into 3 groups: DR, 16 patients; SR, 14 patients; and SR with microfracture (SRM), 20 patients. Patients were evaluated with a visual analog scale (VAS) for pain as well as the Hip Outcome Score–Activities of Daily Living (HOS-ADL), Hip Outcome Score–Sport Specific (HOS-SS), and modified Harris Hip Score (mHHS) both preoperatively and at a minimum 2-year follow-up (mean, 30 months). Results: Among the SR, SRM, and DR groups, the greatest decrease in VAS scores and increase in mHHS, HOS-ADL, and HOS-SS scores were seen in the SRM group, and all the differences were significant ( P < .001 to P = .006). The abductor tendon retear rates were 31.3%, 35.7%, and 15.0% in the DR, SR, and SRM groups, respectively. Retear rates were lower in the SRM group compared with the SR and DR groups ( P = .042); however, there was no significant difference between the SR and DR groups ( P = .32) in terms of retear rates. Conclusion: Endoscopic SR with microfracture was a safe, practical, and effective technique and had the potential advantage of enhancing biological healing at the footprint. The addition of microfracturing the trochanteric footprint significantly lowered the retear rate and provided better functional outcomes than SR and DR without microfracture.

Background. Abdominal and lumbo-pelvic stability alterations may be the origin of lower limb injuries, such as adductor pathology in soccer players. Imbalance can be caused by both intrinsic and extrinsic factors. Methods: In this randomized controlled trial over 8 weeks, 25 female footballers were randomly allocated to an experimental group (isometric abdominal training and gluteus medius-specific training) or a control group (isometric abdominal training). Evaluations were performed at baseline, at the end of the intervention and after a 4-week follow-up period. The exercise protocol in common for both groups included three exercises: Plank, Lateral plank and Bird dog. Specific exercises for the gluteus medius were: Pelvic drop and Stabilization of the gluteus medius in knee valgus. Outcome measures were lumbar-pelvic stability and adductor strength. Results: After the intervention, there was an increase in lumbo-pelvic stability in both groups, being greater in the control group than in the experimental group (mean differences [MD]: 4.84 vs. MD: 9.58; p < 0.01) with differences in the analysis of repeated measures (p < 0.001), but not in group interaction (p = 0.26). Changes were found in adductor strength in the experimental group (MD: −2.48; p < 0.001 in the left adductor; MD: −1.48; p < 0.01 in right adductor) and control group (MD: −1.68; p < 0.001 in the left adductor; MD: −2.05; p < 0.001 in the right adductor) after the intervention, with differences in the analysis of repeated measures in left (p < 0.001) and right (p < 0.001) adductor strength. Conclusions: An abdominal and gluteal training protocol shows no advantage over a protocol of abdominal training alone for lumbo-pelvic stability and adductor strength, while improvements in both variables are maintained at four weeks follow-up.

Pain Symptoms

Background: CrossFit is one of the fastest growing “high-intensity functional training” methods in recent years. Due to the very demanding motion sequences and high loads, it was initially assumed that there was an extremely high risk of injury. However, studies have shown that injury rates are given between 0.74–3.3 per 1000 h of training, which is not higher than in other individual sports such as weightlifting. The purpose of the study was to estimate the type of pain symptoms that are directly related to CrossFit, to estimate the frequency of injuries that occur within a population of recreational CrossFit athletes, and, finally, to identify the factors influencing the frequency of pain during CrossFit training. Methods: A total of 414 active CrossFit athletes completed an online survey inclusive of 29 items focusing on individual physical characteristics and training behavior, as well as simultaneous or previously practiced sports. Results: There was a significantly higher proportion of knee pain in athletes who had previously or simultaneously played another sport (p = 0.014). The duration, intensity, or type of personal training plan developed, along with personal information such as age, gender, or BMI, had no significant influence on the pain data. We could not find any significant variance between the groups that we formed based on the differently stated one-repetition max (RMs). There were differences in athletes who stated that they did specific accessory exercises for small muscle groups. Above all, athletes performing exercises for the hamstrings and the gluteus medius indicated fewer pain symptoms for the sacro-iliac joint (SIJ)/iliac and lower back locations. Conclusions: It is important not to see CrossFit as a single type of sport. When treating a CrossFit athlete, care should be taken to address inter-individual differences. This underlines the significant differences of this study between the individual athletes with regard to the ability to master certain skills or their previous sporting experience. The mere fact of mastering certain exercises seems to lead to significantly more pain in certain regions. In addition, there seems to be a connection between the previous or simultaneous participation in other sports and the indication of pain in the knee region.

Many stroke patients rely on cane or ankle-foot orthosis during gait rehabilitation. The purpose of this study was to investigate the immediate effect of functional electrical stimulation (FES) to the gluteus medius (GMed) and tibialis anterior (TA) on gait performance in stroke patients, including those who needed assistive devices. Fourteen stroke patients were enrolled in this study (mean poststroke duration: 194.9 ± 189.6   d ; mean age: 72.8 ± 10.7   y ). Participants walked 14 m at a comfortable velocity with and without FES to the GMed and TA. After an adaptation period, lower-limb motion was measured using magnetic inertial measurement units attached to the pelvis and the lower limb of the affected side. Motion range of angle of the affected thigh and shank segments in the sagittal plane, motion range of the affected hip and knee extension-flexion angle, step time, and stride time were calculated from inertial measurement units during the middle ten walking strides. Gait velocity, cadence, and stride length were also calculated. These gait indicators, both with and without FES, were compared. Gait velocity was significantly faster with FES ( p = 0.035 ). Similarly, stride length and motion range of the shank of the affected side were significantly greater with FES (stride length: p = 0.018 ; motion range of the shank: p = 0.02 6). Meanwhile, cadence showed no significant difference ( p = 0.238 ) in gait with or without FES. Similarly, range of motion of the affected hip joint, knee joint, and thigh did not differ significantly depending on FES condition ( p = 0.115 ‐ 0.529 ). FES to the GMed and TA during gait produced an improvement in gait velocity, stride length, and motion range of the shank. Our results will allow therapists to use FES on stroke patients with varying conditions.

Background: Open repair for gluteus medius and minimus tears is a common surgical treatment for patients with lateral hip pain associated with abductor tears; however, clinically meaningful outcomes have not been described after open surgical treatment. Purpose: To define the minimal clinically important difference (MCID) in patient-reported outcome measures (PROMs) in patients undergoing open gluteus medius or minimus repair, and to identify preoperative patient characteristics predictive of achieving MCID postoperatively. Study Design: Case series; Level of evidence, 4. Methods: A retrospective review of prospectively collected data from a consecutive series of patients undergoing open abductor repair between July 2010 and April 2019 was conducted. Perioperative patient data collected included patient characteristics and preoperative and postoperative modified Harris Hip Score (mHHS) and International Hip Outcome Tool (iHOT-33) score. Paired t tests were utilized to compare preoperative and postoperative PROMs and MCID was calculated for both PROMs. Multivariate logistical regression analysis was used to assess the association between preoperative variables and the likelihood for achieving MCID. Results: A total of 47 patients were included in the study. The majority of patients were female (78.7%), with an average age of 63 ± 10.7 years. The average follow-up for both the mHHS and the iHOT-33 surveys was 37.8 ± 27.9 months (range, 10-102 months). Patients demonstrated statistically significant improvements on the mHHS and iHOT-33 postoperatively ( P < .001 for both). The MCIDs of mHHS and iHOT-33 were calculated to be 9.9 and 14.3, respectively. Overall, 82.9% of patients achieved MCID for mHHS and 84.1% of patients achieved MCID for iHOT-33 postoperatively. Multivariate logistical analysis demonstrated younger patients were less likely to achieve MCID for both outcome measures. Four patients (8.5%) suffered postoperative complications after open repair. Conclusion: This study defined MCID for mHHS and iHOT-33 for patients undergoing open repair of hip abductor tears, with a large percentage of patients (>80%) achieving meaningful outcomes for both outcome measures. There was a low complication rate. Younger patients were less likely to achieve MCID compared with older patients.

Introduction Periarticular muscles have a significant role in keeping the mobility and integrity of the hip joint. The aim of this article was to investigate the effects of the total hip arthroplasty and early rehabilitation on the muscle strength. Patients Three groups of examined persons (matched in relation to musculosceletal conditions, sex, age and occupation) were included in the investigation. The first group (40 of the involved hip) and the second group (with 33 involved hips) were groups of patients with late-stage of osteoarthritis of the hip. The first group of patients was managed conservatively and the second group operatively (total cemented hip endoprosthesis was performed). The third group was control group with 123 healthy hips. Material and methods The maximal voluntary isometric strength was measured with dynamometer. The muscle strength was tested in all three groups: in the first group of patients at the beginning and at the end of the therapy and in patients of the second group 6?3 months postoperatively. Results A significant improvement of the muscle strength was noted for the flexors (t=2.45, p<0.05), musculus tensor fasciae latae (t=2.35, p<0.05), extensors (t=2.85, p<0.01), adductors (t=3.02, p<0.01), external rotators (t=3.1, p<0.01), m. gluteus medius (t=5.28, p<0.001) and internal rotators (t=5.77, p<0.001) after total hip arthroplasty and early rehabilitation in comparison to the conservatively treated group. Conclusion The muscle strength in the patients with osteoarthritis of the hip after arthroplasty was significantly higher than after rehabilitation for all hip muscles but did not reach values of the strength of the muscles in the corresponding control group.
