RESUMEN
BACKGROUND: Cutaneous neuropraxia is the most common complication following distal biceps tendon repair (DBTR). Currently, no patient demographic factors have been implicated in its occurrence, course, or resolution. The purpose of this study is to explore various patient demographics and their association with postoperative neuropraxia. Further it investigates how mental health scores correlate with patient-reported outcomes, and whether occurrence of neuropraxia alters this association. METHODS: This retrospective review evaluates a consecutive series of patients who underwent distal biceps repair with a single-incision cortical button technique. Patients with reported outcome data at a minimum of 1 year (n = 47) were included for analysis. Demographic data including age, sex, body mass index (BMI), diabetes, smoking status, and occurrence of neuropraxia were recorded. Patient-reported outcome measures (PROMs) include the American Shoulder and Elbow Surgeons-Elbow (ASES-E) score, Single Assessment Numeric Evaluation (SANE) score, Visual Analog Scale (VAS) for pain, Disabilities of the Arm, Shoulder, and Hand Score (QuickDASH), and Veterans RAND 12 (VR-12) Mental Component Score (MCS) and Physical Component Score (PCS) quality-of-life assessment. RESULTS: Postoperative neuropraxia of any duration occurred in 45% (21/47) of patients in this cohort following DBTR. Of these, 62% (13/21) reported resolution of symptoms by the latest follow-up. Mean time to resolution of neuropraxia was 148 days. Patient age, BMI, smoking history, time to surgery, tear thickness, and increasing surgeon experience across the study period were not significantly associated with the incidence or time to resolution of postoperative neuropraxia. Scores for patient satisfaction, VAS, ASES, QuickDASH, SANE, VR-12 MCS, VR-12 PCS, and flexion ROM did not differ significantly between patients with and without postoperative neuropraxia. CONCLUSION: Patient satisfaction following DBTR was not significantly associated with postoperative neuropraxia. Patient and surgical characteristics did not influence the occurrence or time to resolution of neuropraxia. The occurrence of postoperative neuropraxia did not result in significant functional limitations.
RESUMEN
Introduction The important factors determining the treatment of extensor tendon injuries include the anatomical zone, type of injury, mode of injury, chronicity, and pathology of the adjacent tissues (principally the skin, bone, and joints). Very few studies have collectively studied the outcomes of all the wrist, forearm, and hand extensors. Hence, the major aim of this study was to evaluate the results of extensor tendon injuries of the hand, wrist, and forearm that were treated surgically. Methodology This was a hospital-based retrospective study done in a tertiary teaching hospital in South India. A total of 30 patients (23 males, seven females) were included in the study. All the cases of extended tendon injuries of the wrist, hand, and forearm were treated surgically, and those willing to participate were included in the study after obtaining institutional ethics committee approval. Results The study included 30 patients, predominantly males (76.66%). The majority were aged 31-40 years (33.33%). Occupational injuries were the most common cause (36.66%), followed by road traffic accidents (RTAs) and glass cuts (26.66%). Right-sided injuries were more frequent (56.66%), with zone VI being the most affected (43.33%). Extensor digitorum communis was the most injured tendon (40%). Various suture techniques were used, including horizontal mattress and modified Kessler's. Complications occurred in four patients, including hematoma and surgical site infections. Functional outcomes, assessed by Miller's Criteria, indicated extension lag and flexion loss as key recovery measures. Conclusion Hand function is essential for daily life activities, and optimal repair and reconstruction of extensor tendon injuries are crucial to avoid functional disability. While the present study demonstrated positive outcomes, further research with larger sample sizes and more rigorous designs is needed to validate these findings and improve treatment strategies for hand injuries.
RESUMEN
Tendons serve as important weight-bearing structures that smoothly transfer forces from muscles to skeletal parts, allowing contracted muscle movements to be translated into corresponding joint movements. For body mechanics, tendon tissue plays an important role. If the tendons are damaged to varying degrees, it can lead to disability or pain in patients. That is to say, tendon injuries havea significant impact on quality of life and deserve our high attention. Compared to other musculoskeletal tissues, tendons are hypovascular and hypo-cellular, and therefore have a greater ability to heal, this will lead to a longer recovery period after injury or even disability, which will significantly affect the quality of life. There are many causes of tendon injury, including trauma, genetic factors, inflammation, aging, and long-term overuse, and the study of related mechanisms is of great significance. Currently, tendon there are different treatment modalities, like injection therapy and surgical interventions. However, they have a high failure rate due to different reasons, among which the formation of adhesions severely weakens the tissue strength, affecting the functional recovery and the patient's quality of life. A large amount of data has shown that non coding RNAs can play a huge role in this field, thus attracting widespread attention from researchers from various countries. This review summarizes the relevant research progress on non-coding RNAs in tendon injuries, providing new ideas for a deeper understanding of tendon injuries and exploring new diagnostic and therapeutic approaches.
RESUMEN
(1) Introduction: Tendinous mallet finger is a frequent deformity that occurs after an extensor tendon injury during sports or daily life activities. Despite the existence of numerous non-operative and operative techniques to address this deformity, there is a controversy on its optimal management. In this study, we aimed to present a direct tendon suture technique using the distal interphalangeal (DIP) joint open approach for treating tendinous mallet finger injury. (2) Methods: Between 2019 and 2021, 19 patients with closed non-fracture tendinous mallet fingers underwent the direct tendon and paratenon repair technique. After skin incision, we opened the paratenon with lazy S shape incision and found the ruptured proximal and distal tendon ends. We reapproximated the tendons using a simple interrupted suture with Prolene #6/0. After that, we meticulously performed paratenon repair using PDS #6/0 for preventing readherence. Temporary trans-articular Kirschner wire fixation was used for 4 weeks. (3) Results: All patients were followed-up for 3-8 months (mean: 4.8 months). The mean final extension lag was 6.5 degrees, and the overall rate of cases with excellent and good outcomes using Crawford's criteria was 85%. (4) Conclusions: In conclusion, this surgical approach could be a reliable alternative for the treatment of tendinous mallet finger injuries.
RESUMEN
OBJECTIVE: Percutaneous repair is an alternative to open surgical repair of the Achilles tendon with comparable, functional results and low re-rupture and infection rates; however, sural nerve injury is a known complication. The purpose of this study is to design a new surgical procedure, the minimally invasive peritendinous submembrane access technique (MIS-PSAT). It offers optimal results, with excellent functional outcomes, and with minimal soft tissue complications and sural nerve injury. METHODS: This retrospective study included 249 patients with acute closed Achilles tendon ruptures treated at our institution between 2009 and 2019. All patients underwent MIS-PSAT at our institution and were followed up for 8-48 months. Functional evaluation was based on the Achilles tendon total rupture score (ATRS) and the American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS-AHS), associated with local complications and isokinetic tests. RESULTS: None of the patients had infection, necrosis, or sural nerve injury. Re-rupture occurred in two cases. The average times to return to work and sports was 10.4 and 31.6 weeks, respectively. The average ATRS and AOFAS-AHS scores were 90.2 and 95.7, respectively, with an excellent rate of 99.5%. Isokinetic tests showed that ankle function on the affected side was comparable with that on the healthy side (p > 0.05). CONCLUSION: The MIS-PSAT for acute Achilles tendon rupture is easy to perform with few complications. Importantly, the surgical technique reduces the risk of sural nerve injuries. Patients have high postoperative satisfaction, low re-rupture rates, and muscle strength, and endurance can be restored to levels similar to those on the healthy side.

(1) Background: The Festival of Sacrifice, commonly known as Eid al-Adha, has a profound religious and cultural impact on nations with a Muslim majority. This festival is celebrated every year in Muslim countries; however, it is a time in which patients present to the emergency department with serious injuries. In our study, we examined current injuries occurring during Eid al-Adha in one of the largest hospitals in Türkiye, providing the largest patient population to date. This included mapping tendon and maxillofacial injuries, a first in the literature. To the best of our knowledge, this is the largest case series of injuries sustained during Eid al-Adha. The significance of this study lies in its potential to significantly benefit patients and healthcare systems by providing reference data. (2) Methods: Patients admitted to Ankara City Hospital during Eid al-Adha between 2019 and 2023 were examined. The demographic characteristics, injury patterns, and injury sites of patients admitted on the four days of Eid al-Adha were collected and analyzed. Maxillofacial traumas during the festival were analyzed. Tendon injuries on the left hand, which is the most commonly injured body part in the literature, were mapped into a figure. To compare the change in the number of patients, a comparison was made with the number of patients in our hospital for four consecutive days 2 weeks before Eid. Statistical analysis was performed using IBM SPSS Statistics for Windows. (3) Results: A total of 610 patients, including 101 female and 509 male patients, were included in this study. A statistically significant increase (p < 0.001 for all years) in hospital admission due to injury was observed. Individuals between the ages of 30 and 40 years were the most frequently admitted patients (n = 182, 29.8%). Knife injuries were significantly more common in all patients (p < 0.001). When the total number of patients was evaluated in terms of injured areas where patients present to the emergency department, left-hand injuries were found to be significantly more common than injuries in other areas (p < 0.001 for all). The extensor pollicus longus tendon was the most commonly injured tendon among all extensor and flexor tendon injuries (n = 104). The most commonly injured tendon was the flexor tendon in zone 2 of the first finger (n = 45). This study showed that injuries to the extensor tendon in zone 1 of the fifth finger, the flexor tendon in zone 4 of the first finger, and the flexor tendon in zone 1 of the fifth finger were never seen. Twenty-five patients with maxillofacial injuries were admitted to the hospital. Orbital floor fractures were the most common type of maxillofacial injury. The anesthesia technique we preferred for all patients was local anesthesia (n = 267). Wide-awake local anesthesia no tourniquet (WALANT) was the second most preferred anesthetic technique. The number of patients who were selected in a random 4-day period for each year were compared with the number of patients who came during Eid al-Adha. The Mann-Whitney U tests revealed a significant increase in injuries on the first day of Eid al-Adha compared to non-festival days (p < 0.001). However, no significant differences were observed on the subsequent days or in the overall injury counts during the festival period (p = 0.841 for day 2, p = 0.151 for day 3, p = 0.310 for day 4). (4) Conclusions: According to this study, which is the largest known case series in the literature, the number of patients admitted to the hospital increased annually. In our study, we observed a significant increase in injuries only on the first day of Eid al-Adha compared to a randomly selected 4-day period of the same year. Left-hand extensor tendon injuries from a knife were the most common injuries in middle-aged men. The extensor pollicis longus tendon was the most commonly injured extensor tendon, with zones 3 and 4 being the most commonly affected. The flexor pollicis longus tendon was the most commonly injured flexor tendon in zone 2. During this period, patients may not only need hand surgery but also maxillofacial plastic surgery. We recommend, in addition to the indications I,n the literature that during Eid al-Adha, the WALANT technique should be widely adopted in patients where local anesthesia will be insufficient. We also recommend utilizing a diagram to manage the patient load during Eid al-Adha and prevent overburdening the healthcare system.

Teaching point: An irreducible anterior glenohumeral joint dislocation associated with a displaced fracture of greater tuberosity, a rotator cuff tear, or a coracoid process fracture should raise the suspicion of posterior long head of biceps tendon (LHBT) dislocation.
RESUMEN
Simultaneous bilateral rupture of the quadricipital tendon is an extremely rare lesion. We report a case of this injury after low-energy trauma in a patient with type-II diabetes mellitus. Both knees were surgically approached in the same surgical procedure. Early rehabilitation is essential for the adequate functional recovery of the knee. The aim of the present report was to describe an atypical case of this type of injury after minimal trauma, as well as to detail the surgical technique used to treat it.
RESUMEN
Objective: To evaluate the safety and effectiveness of a modified pull-out suture technique in patients undergoing primary repair surgery for injuries to the flexor tendons of the fingers with Total Active Motion (TAM) as the primary outcome. Method: A total of 29 patients (38 fingers) were chosen from both sexes, aged between 18 and 65 years with clean acute tendon laceration occurring within 15 days, in the Verdan's zone II of flexor tendon in the hand, when only the deep flexor tendon was sutured, either associated or not with digital nerve injury. The patients were operated on using the proposed technique and evaluated at 3, 9 and 24-weeks PO. The primary outcome was the assessment of Total Active Movement (TAM) and 3 classifications were employed: Strickland, IFSSH and Buck-Gramcko. Results: We observed a total active motion (TAM) of 209.3 °at the end of 24 weeks; 83.0% of Good and Excellent results by the Modified Strickland Classification, 93% of Excellent results by the IFSSH Classification, and 97% of Good and Excellent results using the Buck-Gramcko Classification. There were no cases of rupture, but tendon adhesion was observed in 3 fingers. Conclusion: The present suture technique proved to be safe and effective with a low rate of complications, obtaining an excellent functional result in terms of total active mobility, according to the evaluations and classifications used.
RESUMEN
OBJECTIVE: The aim of this study was to evaluate the effectiveness of mirror therapy and to provide a clinical basis for better functional recovery in the rehabilitation of patients with flexor tendon injury. MATERIALS AND METHODS: Thirty patients were included and randomly divided between two groups: mirror therapy and conventional treatment. A physical therapy program consisting of whirlpool, ultrasound and transcutaneous electrical nerve stimulation was applied to both groups. In the mirror therapy group, flexor tendon gliding, blocking exercises, joint range of motion and resistance exercises were performed with the healthy hand via a mirror. In the conventional treatment group, the same exercises were performed with the affected hand without mirror. This treatment was continued for 12 sessions over 4 weeks. Joint range of motion, handgrip strength, pain, functionality, dexterity and kinesiophobia were evaluated before and after treatment. RESULTS: More improvement was observed in the mirror therapy group in terms of pain on visual analog scale, Patient-Rated Wrist Evaluation, Hand Function Index and Disabilities of the Arm, Shoulder and Hand scores (p = 0.025, p = 0.004, p < 0.001 and p < 0.001, respectively). There was no significant difference between groups for the other parameters (Tampa Kinesiophobia Scale, Purdue Pegboard test, total active range movement, or handgrip strength: p > 0.05). CONCLUSION: This study shows that mirror therapy in postoperative rehabilitation of flexor tendon injuries is more effective than conventional in terms of reducing the severity of pain and restoring hand function.

Objective:To evaluate the outcomes of reconstruction with half of peroneous longus tendon autograft for the treatment of chronic Achilles tendon rupture combined with tendon defects.Methods:A retrospective case series study was conducted on the clinical data of 14 patients with chronic tendon rupture combined with defects admitted to Orthopedic Sports Medicine Center, West China Hospital, Sichuan University from November 2017 to August 2020, including 11 males and 3 females, aged 26-62 years [(42.8±10.7)years]. All the patients underwent Achilles tendon reconstruction with half of peroneus longus tendon autograft. American Orthopedic Foot and Ankle Society (AOFAS) score, Achilles tendon total rupture score (ATRS) and Visual Analogue Scale (VAS) were compared before surgery, at 12 months after surgery and at the last follow-up. At the last follow-up, MRI of the injured ankle was prescribed to evaluate tendon healing; Thomspon test was performed and the patients were asked to do single-leg heel raise; the patients were asked about their conditions in returning to daily life activities and sports. Postoperative complications were observed.Results:All the patients were followed up for 24-47 months [(35±9)months]. AOFAS score, ATRS and VAS at 12 months after surgery were (87.9±6.6)points, (80.9±2.4)points and (2.0±0.3)points respectively, superior to those before surgery [(52.7±16.9)points, (42.0±4.4)points and (4.1±0.4)points respectively] ( P<0.05). The afore-mentioned results at the last follow-up were (95.2±7.2)points, (85.9±2.5)points and (0.8±0.3)points respectively, superior to those at 12 months after surgery ( P<0.05). MRI images of the affected ankle joints showed satisfactory healing of the reconstructed Achilles tendon at the last follow-up. All the patients, being negative in Thompson test at the last follow-up, were able to complete the heel lift on the affected side. All the patients resumed activities of daily living at the last follow-up, among whom 5 resumed to moderate- to high-intensity sports activities, such as basketball sport, and moderate-to high-intensity physical training, 5 resumed light-intensity sports activities such as jogging and swimming, and the other 4 did not resume sports due to fear of re-injury or aging. One patient had delayed wound healing, which was considered gout-related. One patient complained about mild pain at the Achilles tendon in cold weather or after long walks. No re-rupture of the Achilles tendon occurred. No patient complained about discomfort at the graft harvest site, calcaneal valgus or restricted ankle plantar flexion. Conclusions:For patients with chronic Achilles tendon rupture combined with tendon defects, reconstruction with half of peroneous longus tendon autograft facilitates postoperative spinal function recovery and pain alleviation, achieves satisfaction with the returning to daily activity and sports, and has few complications.

BACKGROUND: The forearm/wrist squeeze/compression test has been used to examine digital flexor tendon injuries with varied names. Furthermore, the test has not been minutely described and its mechanism remains unclear. We renamed the test the "distal forearm squeeze test". The purpose of this study was to elaborate on the test and elucidate the mechanism. METHODS: Two patients with digital flexor tendons ruptured in zone 3 and zone 1 respectively and 50 outpatients with intact digital tendons underwent the test. Then the test was performed on 3 chickens under 4 conditions. First, when the digital flexor and extensor tendons were all intact. Second, after the flexor tendons of the third toe were transected. Third, after the flexor tendons of all toes of the foot were transected. Finally, after the flexor and extensor tendons of all toes of the foot were transected. RESULTS: In the patient with digital flexor tendons ruptured in zone 3, the test showed that the injured digit was flexed slightly while the uninjured digits were flexed obviously. In the patient with digital flexor tendon ruptured in zone 1, after separate stabilization of the proximal interphalangeal (PIP) joints of the injured and uninjured fingers in extension, the test showed that the distal interphalangeal joint of the patient's injured finger had no response, while those of the uninjured fingers were flexed. All 50 subjects showed clenched or half-clenched hands in response to the test. The test showed that all toes were flexed when the digital tendons of the chicken were intact. All toes were flexed except the third toe after the flexor tendons of the third toe were transected. All toes were extended after all the digital flexor tendons were transected. All toes had no response after all the digital flexor and extensor tendons were transected. CONCLUSIONS: The distal forearm squeeze test is valuable in examining digital flexor tendon injuries. If only the flexor digitorum profundus tendon is examined, the PIP joint of the finger should be stabilized in extension during the test.

Background: In Flexor Pollicis Longus (FPL) injuries, primary repair with end-to-end suture is the treatment of choice. In cases where primary repair is not possible, tendon transfer or tendon grafting is used, each of which has its strengths and weaknesses. We aimed to investigate the effectiveness of each of the above two methods in patients. Methods: Patients with FPL injury who referred to Hazrat Fatemeh Hospital, Tehran, Iran late in 2020 to 2021, if primary tendon repair was not possible, were randomly repaired with tendon transfer or tendon graft. After the appropriate time, the splint was opened and physiotherapy was performed for the patients. Then, at least three months after the repair, the range of motion of the IP and MP joints of the patients thumb was measured and compared in two groups. Results: Ten patients in the tendon transfer group and 10 patients in the tendon graft group were studied. In the secondary repair of FPL with tendon grafting, the range of motion of both IP and MP joints of the thumb was not significantly different compared to repair with tendon transfer. Conclusion: The findings of this research confirm controversies in this field. In order to obtain more accurate results, it is suggested to carry out a research with a larger number of patients and with strict control over the surgical technique and post-operative care, as well as taking into account the morbidities caused by donor tendon removal and examining the overall satisfaction of the patients.
RESUMEN
Objective The aim of this study is to analyze various rehabilitation protocol and determine which methods will yield a better outcome. Methods The database reports were searched within 1990 until 2020, using PubMed, Cochrane library database, Ovid, Medline, and the other several published trials. A statistical analysis was made from Review Manager and Trial Sequential Analysis (TSA). Result The mean of re-rupture rate is 3.3% ( n = 8) in the combination protocol until 8% ( n = 48) in CAM protocol. Meta-analyses found no significant difference between Kleinert vs CAM in re-rupture rate. Also no significant difference in Duran vs CAM in rerupture rate. In Trial Sequential Analysis (TSA), the z-curve does not cross both of the trial sequential boundaries, a further trial with larger sample will be required. The TSA of flexion contracture CAM vs Kleinert was indicated that CAM protocol may be superior than Kleinert to reduce the incidence of flexion contracture. For the range of mean flexion contracture 6.6% ( n = 18) in CAM to 23.6% ( n = 76) in Kleinert protocol. Conclusion Current meta-analysis proposed that the combination technique will result less re-rupture incidence and better functional outcome in flexor zone II injuries than other techniques. The CAM method also results less flexion contracture than others. However, a further meta-analyses with larger sample trials will be required to confirm this review's conclusion.
RESUMEN
Acute distal biceps injuries clinically present with sudden pain and acute loss of flexion and supination strength. The main injury mechanism occurs during the eccentric load of the biceps. The hook test is the most significant examination test, presenting the highest sensibility and specificity for this lesion. Magnetic resonance imaging, the gold standard imaging test, can provide information regarding integrity and identify partial and/or complete tears. The surgical treatment uses an anterior or double approach and several reattachment techniques. Although there is no clinical evidence to recommend one fixation method over the other, biomechanical studies show that the cortical button resists better to failure. Although surgical treatment led to an 89% rate of return to work in 14 weeks, the recovery of high sports performance occurred in 1 year, with unsustainable outcomes.
RESUMEN
BACKGROUND: Diabetic foot ulcers often affect tendon tissue. Consequently, the infection may spread proximally along the tendon, leading to amputation or even the death of patients. Exposed, degenerated, and necrotic tendons are key factors affecting the healing of diabetic foot ulcers. The effective treatment of the tendon involvement may positively affect the prognosis. In clinical practice, treatment with Shengji ointment and bromelain induces islands of granulation tissue on the denatured tendon surface, which gradually grows and merges. Ideally, the exposed tendon is covered entirely by granulation tissue. This trial aims to assess the effect of a combined treatment regime of Shengji ointment, which has been shown to regenerate muscle tissue and pineapple protease in preventing the loss of function and amputation caused by tendon necrosis. This trial will provide high-quality evidence for the effectiveness of this combination in healing diabetic ulcers with tendon necrosis. METHODS: The sample size will be 180 patients who will be randomly assigned 1:1 to a treatment group (90 patients) using Shengji ointment combined with bromelain and a control group (90 patients) using hydrocolloid dressing. Both groups will continue their conventional treatments, such as blood glucose and blood pressure medication, lipid regulation, antiplatelets, and others. The primary outcome will be the wound coverage with granulation tissue. Secondary outcomes will be the wound healing rate, amputation extent (where needed), time to granulation, and the Maryland Foot Score. Other efficacy outcomes will be the time to debridement of necrotic tendon tissue and granulation tissue score. DISCUSSION: This study will treat patients with diabetic foot ulcers with exposed, degenerated, and necrotic tendons with Shengji ointment and bromelain. The trial aims to promote regeneration and healing, to preserve the limb and its function, and to develop a comprehensive and effective protocol that can be applied to promote the healing of exposed tendons in diabetic foot wounds. TRIAL REGISTRATION: ChiCTR2000039327 ; date of registration: 2020-10-23.

The therapeutic role of tendon stem cells (TSCs) in tendon-related injuries has been well documented. Small extracellular vesicles (sEVs) are being increasingly used as new biotherapeutic agents for various diseases. Therefore, the potential function of TSC-sEVs in tendon injury repair warrants further investigation. In this study, we explored the effects of TSC-sEVs on TSC proliferation, migration, and differentiation in vitro in an autocrine manner. We further used a novel exosomal topical treatment with TSC-sEVs loaded with gelatin methacryloyl (GelMA) hydrogel in vivo; we mixed sufficient amounts of TSC-sEVs with GelMA hydrogel to cover the damaged molded Achilles tendon tissue and then exposed them to UV irradiation for coagulation. GelMA loading ensured that TSC-sEVs were slowly released at the injury site over a long period, thereby achieving their full local therapeutic effects. Treatment with TSC-sEVs loaded with GelMA significantly improved the histological score of the regenerated tendon by increasing the tendon expression while inhibiting the formation of excessive ossification and improving the mechanical properties of the tissue. Moreover, miRNA sequencing in TSC-sEVs, TSCs, and TSCs receiving sEVs revealed that TSC-sEVs altered the miRNA expression profile of TSCs, with increased expression of miR-145-3p. In conclusion, our study demonstrates that TSC-sEVs can play a key role in treating tendon injuries and that loading them with GelMA can enhance their effect in vivo. Moreover, miR-145-3p has a major functional role in the effect of TSC-sEVs. This study offers new therapeutic ideas for the local treatment of Achilles tendon injuries using sEVs. STATEMENT OF SIGNIFICANCE: In this study, we demonstrated that TSC-sEVs play a key role in treating tendon injuries and that loading them with GelMA hydrogel can act as a fixation and slow release in vivo. Moreover, it identifies the major functional role of miR-145-3p in the effect of TSCs that were identified and validated by miRNA sequencing. Our study provides a basis for further research on GelMA slow-release assays that have potential clinical applications. It offers new therapeutic ideas for the local treatment of Achilles tendon injuries using TSC-sEVs.

Objectives: The study aimed to evaluate the clinical and radiological results after endoscopic repair of gluteus medius muscle injuries and proposed an anatomical classification for the different injury classes. Methods: A retrospective case series, including patients who had undergone endoscopic repair of the hip abductor tendon. The surgical procedure was standardized. Magnetic resonance imaging (MRI) studies were analyzed, and the injuries were classified into three types: nontransfixing partial-extension (nTPE) tear, transfixing partial-extension (TPE) tear, and transfixing full-extension (TFE) tear. TPE and TFE were considered high-grade tears. The postoperative outcomes were as follows: duration of walking aid requirement, duration of physical therapy, time to return to daily activities, modified Harris Hip score (mHHS) and Nonarthritic Hip Score (NAHS) functional scores, pain visual analog scale (VAS), satisfaction, claudication, Trendelenburg test, and reoperation. Results: Sixteen patients were included (94% women; mean age 65 years), with a mean follow-up of 42 months (12-131, range). Out of the cases with preoperative exams available for analysis, four cases (31%) were nTPE, three (23%) TPE, and six (46%) TFE tears. Thus, 69% of the patients had high-grade injuries. These patients had a higher degree of fat infiltration (P = 0.034), but this was not correlated with inferior postoperative clinical or radiological results. One patient required reoperation due to a recurrent injury. Conclusion: Isolated extra-articular injuries to the tendons of the gluteus medius and minimus evolved satisfactorily after endoscopic repair. Due to the small number of cases, it was not possible to observe differences in outcomes between high-and low-grade injuries.
