The effect of virtual rainforest and a white noise mobile application on satisfaction, tolerance, comfort, and vital signs during arthroscopy.

BACKGROUND AND PURPOSE: This study was conducted to investigate the effect of Virtual Rainforest (VRF) and a White Noise (WN) mobile applications on patient satisfaction, tolerance, comfort, and vital signs during arthroscopic knee surgery. METHODS: This is a randomized, controlled, interventional study. The study was completed with a total of 93 participants, 31 in the VRF group, 31 in the WN group, and 31 in the control group. Data were collected using a Patient Information Form and a Visual Analog Scale for satisfaction, tolerance, and comfort. RESULTS: The results of study showed that there were significant increases in tolerance, satisfaction, comfort, respiratory rate, and oxygen saturation levels and significant decreases in heart rate, systolic and diastolic blood pressures in both VRF and WN groups (p < .05). In the control group, no significant difference was found between the means of the variables before and after the procedure (p > .05). CONCLUSION: According to the results of the study, VRF and WN applied during the arthroscopy procedure increased satisfaction, tolerance, and comfort in patients and had a positive effect on vital signs.

A threshold of lower preoperative mental health is associated with decreased achievement of comfort and capability benchmarks following rotator cuff repair: a retrospective cohort study.

BACKGROUND: Preoperative biomedical patient characteristics are known to affect the time to achievement of clinically significant outcomes (CSOs) following arthroscopic rotator cuff repair (RCR). However, less is known about the association between preoperative mental status and the time to achievement of CSOs. We hypothesize that higher preoperative mental status is associated with faster achievement of CSOs following arthroscopic RCR. METHODS: Patient-reported outcome measures (PROMs) were collected preoperatively and at postoperative intervals up to 2 years. PROMs included pain visual analog scale (VAS), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), Single Assessment Numeric Evaluation (SANE), and Veterans RAND 12-Item Health Survey (VR-12) scores. Threshold values for CSOs were obtained from previous literature. Mean time to achievement of CSOs was calculated using a Kaplan-Meier analysis. A Cox proportional hazards regression analysis was performed to identify preoperative variables associated with earlier achievement of CSOs. RESULTS: Sixty-nine patients with an average age of 59 ± 8 years were included. Patients with higher preoperative mental status, as measured by VR-12 mental component summary (MCS), experienced significantly earlier substantial pain improvement postoperatively (P = .0471). Patients with higher preoperative mental status also achieved CSOs for physical health at earlier time points (P = .0187). Preoperative VR-12 MCS scores ≥ 40 were associated with earlier achievement of CSOs for pain (P = .0005) and physical health (P = .0015). Ninety-eight percent of patients with preoperative MCS scores ≥40 achieved acceptable pain relief at 4.5 months vs. 56% of all other patients at 12.3 months (P = .0001). Patients with preoperative MCS scores ≥40 experienced significantly faster improvement in physical health compared to patients with preoperative MCS scores <40 (P = .0006). CONCLUSIONS: Higher preoperative mental status, especially a preoperative MCS score ≥40, is associated with significantly faster improvement in pain and physical function following arthroscopic RCR. Nearly all patients (98%) with preoperative MCS score ≥40 achieved an acceptable state of pain relief compared with only 56% of patients with preoperative MCS score <40. These findings indicate that a holistic approach with equal consideration of preoperative mental health and rotator cuff pathophysiology is vital to the successful management of rotator cuff tendinopathy.

Editorial Commentary: Postoperative Zoledronic Acid Improves Tendon Healing but Does Not Affect Outcomes in Rotator Cuff Repair Patients With Postmenopausal Osteoporosis.

Understanding the preoperative risk factors for successful rotator cuff repair (RCR) and ways to optimize these factors is an evolving area of study. The Rotator Cuff Healing Index and other proxy risk factors for failed rotator cuff healing have implicated significant fatty infiltration, muscular atrophy, advanced chronological age, tear size and retraction, and ultimately, osteoporosis. Although structural (or biological) augmentation and tendon transfer have been proposed as solutions for the alarmingly high rate of failure after primary RCR, other options may preferentially focus on the enthesis and underlying osseous footprint. Currently, bisphosphonates are frequently used in the treatment of osteoporosis and prevention of fragility fractures. However, burgeoning evidence suggests that postoperative zoledronic acid may have clinical utility after rotator cuff and other tendon repairs. In the cost-conscious world of evidence-based medicine, the added economic burden of additional medications and office visits may or may not improve patient outcomes-much less confer added value. Our advice to fellow shoulder surgeons: Wait for further information, but continue to holistically consider and optimize risk factors for poor soft-tissue healing. Although the addition of postoperative bisphosphonates may improve suture anchor fixation and promote a better foundation for healing, it will not immediately transform your RCR success rates.

The hue of temporomandibular joint arthroscopy under local versus general anaesthesia.

BACKGROUND: Temporomandibular joint arthroscopy (TMJA) is often performed under general anaesthesia (GA) worldwide on an inpatient basis, whereas local anaesthesia (LA) is not equally considered as the standard procedure. OBJECTIVES: To compare the efficacy between LA and GA when performing TMJA. METHODS: This study retrospectively reviewed a total of 182 patients in LA group and 91 patients in GA group who underwent TMJA for the management of disc displacement. Patients were divided into two groups based on type of anaesthesia used for surgery; LA group and GA group. Comparisons were made based on operative time, intubation and extubation time (for GA only), hospital stay duration, total cost and post-operative clinical and radiological outcomes. RESULTS: The demographics and pre-operative clinical assessments were matched in both groups. No post-operative significant difference was found in outcomes when performing TMJA under LA compared to GA in terms of pain reduction (p = .016) and improvement in mouth opening (p = .866). The median operative time and hospital stay duration for LA group were significantly less compared to GA group (p < .001). GA group required an additional intubation and extubation time, whereas LA group patients were waived from it. TMJA for LA group was performed in the minor procedure setup, which reduced the costs for surgery (p < .001). Post-operative disc position was excellent and good with an overall success rate of 95%. CONCLUSION: The use of LA performing TMJA reduces operating time, costs, hospital stay and recovery room time than GA group. Furthermore, TMJA performed under LA shared similar post-operative clinical and radiological outcomes with those performed under GA.

Diagnostic Accuracy of MRI in Knee Meniscus Tear and ACL Injury.

Objective: Knee injuries are very common and may lead to other secondary injuries if effective treatment is lacking. In addition to standardized physical examination, magnetic resonance imaging (MRI) is sometimes considered an aid in the diagnosis of knee trauma. In order to have a more accurate diagnosis of knee injuries, we compared MRI with arthroscopic findings in this study to evaluate the diagnostic accuracy of MRI for meniscal tears and anterior cruciate ligament injuries of the knee. Methods: One hundred and ten patients with suspected meniscal tears and anterior cruciate ligament injuries of the knee who were admitted to our hospital from June 2020 to June 2022 were selected as study subjects, and the clinical data of the patients were retrospectively analyzed. All patients underwent MRI for preoperative diagnosis, and the sensitivity, specificity, MRI findings, and confirmation of diagnosis were compared and analyzed, and the accuracy of MRI in diagnosing meniscal tears and ACL injuries of the knee was analyzed. Results: The mean ACL angle was (98.0 ± 5.4) in the MRI group and (118.0 ± 6.8) in the arthroscopic group, the difference between the two groups was statistically significant P < .05. The mean L/H value of the ACL was (2.12 ± 0.38) in the MRI group and (1.81 ± 0.19) in the arthroscopic group, which was statistically different between the two groups (P < .05). Among the patients, 68 meniscal injuries were found in the MRI examination, including 45 cases of knee meniscal tears and 23 cases of anterior cruciate ligament injuries. The sensitivity, specificity, positive and negative predictive values, agreement rate, kappa value, and Youden index of MRI in diagnosing meniscal tears and ACL injuries were all high. Conclusions: In terms of sensitivity and accuracy, MRI is an excellent imaging technique for the diagnosis of meniscal tears and anterior cruciate ligament injuries of the knee.

The effectiveness of hydrotherapy on return to play in sports following hip arthroscopic surgery: a comparative study.

BACKGROUND: The postoperative management of femoroacetabular impingement (FAI) is variable with favourable surgical outcomes. Yet there is no evidence on the efficacy of hydrotherapy in athletes undergoing hip arthroscopy for FAI. The purpose of this study was to evaluate the role and the impact of hydrotherapy on return to sports following hip arthroscopy for symptomatic FAI. METHODS: 2 cohorts of mixed level of athletes from various sports: a hydrotherapy group that followed land-based exercises in combination with hydrotherapy exercises and a control group that followed solely the same land-based exercises. Pre- and postoperative pain and hip-specific outcome scores were completed, and patient satisfaction was rated. RESULTS: A total of 88 hip arthroscopies were included with a minimum of 2 years follow-up; the hydrotherapy group comprised of 36 hips and the control group, 52 hips. There was a significant improvement in time to return to previous performance (HR 1.91, 95% CI, 1.21-3.01; p = 0.005) in the hydrotherapy group compared with the control. The hip-specific scores and patient satisfaction were considerably improved in the hydrotherapy group. CONCLUSIONS: The analysis of our data indicates that the incorporation of hydrotherapy into postoperative rehabilitation for hip arthroscopy for FAI accelerates the return of athletes to their pre-injury performance, since recovery time decreased significantly.

A scoping review and best evidence synthesis for treatment of partial-thickness rotator cuff tears.

BACKGROUND: Rotator cuff disorders include a broad spectrum of pathological conditions including partial-thickness and full-thickness tears. Studies have shown partial-thickness rotator cuff tear (PTRCT) prevalence to be twice that of full-thickness tears. In the working population, PTRCTs are one of the most common causes of shoulder pain and often result in occupational disability due to pain, stiffness, and loss of shoulder function. Treatment of PTRCTs remains controversial. The purpose of this study was to consolidate the existing high-quality evidence on best management approaches in treating PTRCTs using both nonoperative and operative approaches. METHODS: A scoping review with best evidence synthesis was performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. MEDLINE (OVID), EMBASE (OVID), Cochrane Library (Wiley), SCOPUS, Web of Science Core Collection, CINAHL Plus with Full Text (EBSCOhost), PubMed Central, and Science Direct were searched from 2000 to March 3, 2023. Level 1 studies, and systematic reviews and meta-analyses that included level 1 and 2 studies, were included. RESULTS: The search yielded 8276 articles. A total of 3930 articles were screened after removing 4346 duplicates. Application of inclusion criteria resulted in 662 articles that were selected for full-text review. Twenty-eight level 1 studies, 1 systematic review, 4 meta-analyses, and 1 network meta-analyses were included in the best evidence synthesis. Nonoperative strategies included injections (ie, platelet-rich plasma, corticosteroid, prolotherapy, sodium hyaluronate, anesthetic, and atelocollagen), exercise therapy, and physical agents. Operative interventions consisted of débridement, shaving of the tendon and footprint, transtendon repair, and traditional suture anchor repair techniques with and without tear completion. Both nonoperative and operative strategies demonstrated effectiveness at managing pain and functional outcome for PTRCTs. The evidence supports the effectiveness of surgical intervention in treating PTRCTs regardless of arthroscopic technique. CONCLUSION: The results of this scoping review do not support superiority of operative over nonoperative management and suggest that both strategies can be effective at managing pain and functional outcome for PTRCTs. Surgery, however, is the most invasive and costly approach, with the highest risk of complications such as infection. Other variables such as patient expectation, treating practitioner bias, or preference may change which modalities are offered and in what sequence.

A multi-center, single-blinded, randomized, parallel-group, superiority study to compare the efficacy of manipulation under anesthesia versus intra-articular steroid injection in the treatment of patients with frozen shoulder and a diagnosis of rotator cuff injury or tear by MRI: study protocol for a randomized controlled trial.

BACKGROUND: Frozen shoulder (FS) is a common condition that can cause severe pain and limited range of motion in the shoulder joint. While intra-articular steroid injection has been shown to be an effective treatment for FS, manipulation under anesthesia (MUA) is an alternative treatment that has gained popularity in recent years. However, there is a lack of evidence regarding the effectiveness of MUA on FS patients with concomitant rotator cuff injury or tear. Though a few studies have shown that MUA is not associated with rotator cuff tears, and will not exacerbate the injury, more high-quality studies with bigger sample sizes are needed. Therefore, the aim of this multi-center, single-blinded, randomized, parallel-group, superiority study is to compare the efficacy of MUA versus intra-articular steroid injection in the treatment of FS patients with a diagnosis of rotator cuff injury or tear by MRI. METHODS: A parallel, single-blinded, multi-center randomized controlled trial of 320 patients will be conducted at three hospitals of China. Eligible patients with frozen shoulder and rotator cuff injury or tear diagnosed by MRI will be randomly assigned to, in equal proportions, the manipulation under anesthesia group and the intra-articular steroid injection group via a central randomization system, undergoing a corresponding operation on day one and a sequent physical exercise for 14 days. The primary outcome is the comprehensive efficacy evaluation (total effective rate) and the change of Constant-Murley Score. Outcome assessors and data analysts will be blinded, and participants will be asked not to reveal their allocation to assessors. DISCUSSION: This study aims to explore the superiority of manipulation under anesthesia in reducing pain and improving shoulder function in frozen shoulder patients accompanied with rotator cuff injury. To provide a scientific basis for the dissemination and application of manipulation under anesthesia, and a better knowledge for the role of MUA in the treatment of frozen shoulder accompanied with rotator cuff injury.

Conservative management of a suspected triangular fibrocartilage complex injury utilizing strength training exercises: A case report.

OBJECTIVE: The purpose of this case report is to describe the conservative chiropractic management of a patient with a suspected triangular fibrocartilage complex (TFCC) injury. CLINICAL PRESENTATION: A 36-year-old Brazilian Jiu-Jitsu black belt athlete sought care for left-sided diffuse ulnar pain (numeric pain scale 5/10) with a notable bump over the ulna and weakness when grappling. A working diagnosis of suspected TFCC injury was made. INTERVENTION AND OUTCOME: The patient was treated with forearm and grip strength exercises to rehabilitate the pain and strength loss. Following 6 visits and a home exercise program for 8 weeks, his numeric pain scale decreased to 0/10. CONCLUSION: In this case, it is evident that Triangular fibrocartilage complex injury was successfully treated conservatively without the need for surgical intervention or passive care modalities.

[Effect of acupuncture exercise therapy synchronizing isokinetic muscle strength training for postoperative rehabilitation of meniscectomy under arthroscopy].

OBJECTIVE: To observe the effect of acupuncture exercise therapy synchronizing isokinetic muscle strength training on the motor function, stability and proprioception of knee joint, as well as the anxiety emotion in patients after meniscectomy under arthroscopy. METHODS: A total of 70 patients after meniscectomy under arthroscopy were randomized into an observation group (35 cases, 2 cases were eliminated， 2 cases dropped off) and a control group (35 cases, 2 cases were eliminated, 1 case dropped off). Acupuncture was applied at Chize (LU 5), Neixiyan (EX-LE 4), Dubi (ST 35),Yanglingquan (GB 34), etc. on the affective side in the two groups. After 30 min, the needles of the knee joint area were withdrew, while the needle at elbow was continuously retained, the observation group was given acupuncture exercise therapy synchronizing isokinetic muscle strength training, and the control group was given conventional acupuncture exercise therapy. The treatment was given once a day, 7-day treatment was taken as one course, and totally 4 courses were required in the two groups. Before and after treatment, the knee joint Lysholm score, the knee joint isokinetic muscle strength flexion/extension ratio (H/Q), joint position sense measurement (JPS) and Hamilton anxiety scale (HAMA) score were compared in the two groups. RESULTS: After treatment, the knee joint Lysholm scores and H/Q were increased compared with those before treatment in the two groups (P<0.001), and the knee joint Lysholm score and H/Q in the observation group were higher than those in the control group (P<0.001); the JPS and HAMA scores were decreased compared with those before treatment in the two groups (P<0.001), the JPS and HAMA score in the observation group were lower than those in the control group (P<0.05). CONCLUSION: Acupuncture exercise therapy synchronizing isokinetic muscle strength training can effectively improve the motor function, stability and proprioception of knee joint, as well as the anxiety emotion in patients after meniscectomy under arthroscopy.

Comparison of Therapeutic Effects Between Arthroscopic Debridement and Olecranon Fossa Augmentation Plasty for Elbow Osteoarthritis.

Aim: To compare the efficacy of arthroscopic debridement and olecranon fossa augmentation plasty in patients with elbow osteoarthritis. Methods: Eighty-four patients with elbow osteoarthritis admitted to our hospital were randomly divided into two groups with 42 cases in each group. Patients in the control group received expanded olecranon fossa plasty, while those in the observation group underwent arthroscopic debridement. Then the elbow joint function, VAS score, stress level, and incidence of complications were compared between the two groups. Results: The MEPS score, ROM level, and VAS score, as well as the expression of TNF-α, IL-6, and ACTH between the two groups, were significantly different before and after surgery (P < .05). Moreover, compared to patients in the control group, the MEPS score and ROM level of patients in the observation group were higher than those in the control group after six months since surgery, while VAS score, the levels of TNF-α, IL-6, and ACTH were lower on the second day after surgery (P < .05). Conclusion: Arthroscopic cleaning is more helpful in improving elbow joint function and alleviating pain in patients with osteoarthritis of the elbow compared to olecranon fossa augmentation and reconstruction surgery.

Preoperative vitamin D supplementation is a cost-effective intervention in arthroscopic rotator cuff repair.

BACKGROUND: This study investigates the potential role of preoperative 25(OH)D supplementation as a cost-effective strategy to decrease revision rotator cuff repair (RCR) rates and lower the total health care burden from patients undergoing primary arthroscopic RCR. Previous literature has emphasized the importance of vitamin D on bone health maintenance, soft tissue healing, and outcomes in RCR. Inadequate preoperative vitamin D levels may increase revision RCR rates following primary arthroscopic RCR. Although 25(OH)D deficiency is common in RCR patients, serum screening is not routinely performed. METHODS: A cost-estimation model was developed to determine the cost-effectiveness of both preoperative selective and nonselective 25(OH)D supplementation in RCR patients in order to reduce revision RCR rates. Prevalence and surgical cost data were obtained from published literature through systematic reviews. Cost of serum 25(OH)D assay and supplementation were obtained from public-use data. Mean and lower and upper bounds of 1-year cost savings were calculated for both the selective and nonselective supplementation scenarios. RESULTS: Preoperative 25(OH)D screening and subsequent selective 25(OH)D supplementation was calculated to result in a mean cost savings of $6,099,341 (range: -$2,993,000 to $15,191,683) per 250,000 primary arthroscopic RCR cases. Nonselective 25(OH)D supplementation of all arthroscopic RCR patients was calculated to result in a mean cost savings of $11,584,742 (range: $2,492,401-$20,677,085) per 250,000 primary arthroscopic RCR cases. Univariate adjustment projects that selective supplementation is a cost-effective strategy in clinical contexts where the cost of revision RCR exceeds $14,824.69 and prevalence of 25(OH)D deficiency exceeds 6.67%. Additionally, nonselective supplementation is a cost-effective strategy in clinical scenarios where revision RCR cost is ≥$4216.06 and prevalence of 25(OH)D deficiency is ≥1.93%. CONCLUSIONS: This cost-predictive model promotes the role of preoperative 25(OH)D supplementation as a cost-effective mechanism to reduce revision RCR rates and lower the overall health care burden from arthroscopic RCR. Nonselective supplementation appears to be more cost-effective than selective supplementation, likely due to the lower cost of 25(OH)D supplementation compared to serum assays.

Analysis of Isokinetic Strength Test in Arthroscopic Meniscus Suture to Improve Knee Joint Strength and Function.

Objective: This study is aimed to examine the correlation between the transitions in the muscular strength pre and post arthroscopic meniscus suture surgery. Methods: A total of 87 patients records were collected from the electronic medical records of the Second Affiliated Hospital of Soochow University from 2020 to 2021. Patients in the operative group underwent arthroscopic meniscus sutures. The isokinetic muscular strength test system (ISOMED2000) tool was utilized to examine the isokinetic intensity of the knee joins on both sides and the balance was marked and adjusted to the training methods before the test. The HSS score was used to assess the transitions in the knee activity. Results: There was a significant variation in the extensor muscle strength found on the affected portion where F value was observed at 3747.845 (P < .01). The extensor knee joint strength of the affected side was less than the healthy side when compared with pre-operation, one month, three months, and six months post-surgery where F values were found to be 5287.41, 5510.517, and 1947.91 respectively (P < .001). After six months of the surgery, there was an improvement in the isokinetic muscular strength of patients, where the measurement of the damaged side and the healthier side was observed as 89.11 ± 6.78 and 93.45 ± 5.59, respectively. Conclusion: Arthroscopic meniscus suture surgery is observed to have a superior influence on the treatments. After 6 months of surgery, the muscular force of the knee extensor on the affected joint portion enhanced remarkably in contrast to the other durations.

Olympic fencer with femoroacetabular impingement syndrome uses active rehabilitation to avoid surgery: A case report.

INTRODUCTION: Femoroacetabular impingement (FAI) syndrome is a musculoskeletal condition characterized by hip symptoms. Conservative therapy is indicated prior to surgical intervention. However, no literature has described conservative management of FAI in detail. This report provides a detailed active rehabilitation plan for an elite athlete with FAI to guide future research and clinicians. CASE PRESENTATION: A 30-year-old male Olympic fencing athlete presented with unilateral hip pain less than 1 year prior to the Olympic Games. Radiographic imaging demonstrated bilateral cam morphology. Hip mobilizations and stretching did not provide a meaningful pain reduction. Cortisone injection was then suggested prior to the Games where surgery was suggested following the Games. MANAGEMENT AND OUTCOME: Active rehabilitative exercises targeted motor control of the lumbo-pelvic-hip complex, which led to significant pain reduction and full return to sport. Surgical intervention and cortisone injections were deemed unnecessary due to resolution of symptoms. CONCLUSION: Athletes with FAI syndrome may benefit from specific active rehabilitation exercises. Future clinical trials should explore rehabilitative exercises that address improved motor control to manage individuals with FAI syndrome.

Editorial Commentary: Social Determinants of Health Influence the Success of Shoulder Rotator Cuff Repair Outcomes: When You Do Everything Right, Yet Things Still Go Wrong.

Our ability to perform a technically sound surgery is not sufficient to ensure patients have an excellent clinical outcome. Social determinants of health disparities (SDHDs) profoundly impact health equality. Health disparities that exist in the United States are risk factors for inferior patient-reported outcomes and result in greater complication rates following rotator cuff repair surgery. The presence of SDHDs was associated with an increased risk of revision, stiffness, emergency department visits, medical complications, and costs. Economic and educational SDHDs were associated with the greatest risk of 1-year revision surgery. Improved understanding of these social variables can help with risk identification preoperatively. Surgeons may employ additional, holistic, bio-psycho-social, perioperative resources to provide high-quality, value-based care to at-risk patients who might be marginalized by our health care system.

Effectiveness of Exercises With Electromyographic Biofeedback in Conservative Treatment of Massive Rotator Cuff Tears: A Randomized Controlled Study.

OBJECTIVE: The aim of the study is to investigate the effectiveness of a rehabilitation program with electromyographic biofeedback compared with the control group on patients with massive rotator cuff tear. DESIGN: Forty-six adults with massive rotator cuff tears, randomly assigned to 2 groups (23 electromyographic biofeedback group vs. 23 control group). The electromyographic biofeedback group (experimental group) performed the exercises under the guidance of electromyographic biofeedback, unlike the control group. All patients underwent a 45-minute training session a day, 3 times a week over a 6-wk duration, and followed up until 1-year. The outcome measures were American Shoulder and Elbow score, shoulder flexion strength, shoulder range of motion, Numeric Pain Rating Scale, and Global Rating of Change Scale. RESULTS: Compared with the control group, the electromyographic biofeedback group demonstrated a significant change in shoulder flexion strength and patient satisfaction from baseline to 6 wks (posttraining) and from baseline to 12-mo follow-up ( F = 4.671, P = 0.005). There were significant improvements in within groups statistics for American Shoulder and Elbow score, shoulder flexion strength, shoulder range of motion, and Numeric Pain Rating Scale in both groups ( P < 0.05). CONCLUSIONS: The results demonstrate that deltoid-focused structured rehabilitation program combined with electromyographic biofeedback can be used to increase shoulder flexion strength and patient satisfaction in conservative treatment of massive rotator cuff tear.

Suspension fixation of iliac bone grafts under arthroscopy is an effective method for the treatment of unstable bony Bankart disease of the shoulder joint in patients with joint relaxation.

PURPOSE: To evaluate the results of arthroscopic autologous iliac bone graft suspension fixation combined with the Remplissage procedure in the treatment of recurrent shoulder dislocation with bony Bankart lesions and joint hyperlaxity. METHODS: From 2018 to 2020, 22 patients with joint laxity underwent arthroscopic autologous iliac bone graft suspension fixation and Bankart repair combined with the Remplissage procedure due to recurrent shoulder dislocation. Clinical assessment included range of motion (forward flexion, abduction, 90° external rotation, conventional external rotation, adduction, and internal rotation), visual analog scale (VAS) score, Rowe score, University of California Los Angeles (UCLA) score, and Western Ontario Shoulder Instability Index (WOSI) score. Post-operatively, the healing of the bone graft was evaluated with computed tomography (CT) scanning. RESULTS: All 22 patients were followed up for a mean of 19.3 ± 4.1 months. CT imaging showed that the healing time of the bone graft was 6-8 weeks. The patient satisfaction rate was 100%, there were no cases of redislocation, all patients returned to their preinjury training state, and the fear test was negative. At the final follow-up, the UCLA, VAS, Rowe, and WOSI scores were 29.8 ± 2.1, 2.2 ± 0.8, 89.4 ± 4.2, and 482.3 ± 46.2, respectively (p < 0.001). CONCLUSION: Arthroscopic autologous iliac bone graft suspension fixation and Bankart repair combined with the Remplissage procedure are effective in preventing recurrent instability with joint hyperlaxity. Furthermore, no patient had redislocation. LEVEL OF EVIDENCE: IV.

Effects of Modified Duhuo Jisheng Decoction Combined with Arthroscopic Surgery on Bone Metabolism, Oxidative Stress, and Serum TLR4 and TGF-ß1 in Patients with Knee Osteoarthritis.

Objective: To analyze the effects of modified Duhuo Jisheng Decoction combined with arthroscopic surgery on bone metabolism, oxidative stress, and serum TLR4 and TGF-ß1 in patients with knee osteoarthritis (KOA). Methods: Prospectively select 82 patients with KOA from January 2020 to January 2022 in our hospital and divide them into the control group and observation group according to the random number table method, with 41 patients in each group. The control group was treated with arthroscopic surgery alone and routine anti-infection after operation. The observation group was treated with Duhuo Jisheng Decoction on the basis of the treatment of the control group. The patients in the two groups were treated continuously for 4 weeks. The improvement of patients' symptoms was evaluated by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Before treatment and 4 weeks after treatment, the scores of traditional Chinese medicine (TCM) symptoms, bone metabolism indicators (cartilage oligomeric matrix protein (COMP), collagen type II carboxy terminal peptide (ctx-II), and matrix metalloproteinase-3 (MMP-3)), oxidative stress indicators (superoxide dismutase (SOD), glutathione peroxidase (GSHPx), malondialdehyde (MDA), nitric oxide (NO)), serum Toll-like receptor 4 (TLR4), and transforming growth factor ß (TGF-ß) level were compared between the two groups. Results: After treatment, the WOMAC score of the two groups decreased (42.45 ± 10.83) in the observation group and (67.81 ± 14.63) in the control group. The WOMAC score of the observation group was lower than that of the control group (P < 0.05). After treatment, the levels of COMP, CTX-II, and MMP-3 in the two groups decreased, and the levels of COMP, CTX-II, and MMP-3 in the observation group were lower than those in the control group (P < 0.05). After treatment, the levels of SOD and GSHPx increased, while the levels of MDA and NO decreased in the two groups. The levels of SOD and GSHPx in the observation group were higher than those in the control group, while the levels of MDA and NO were lower than those in the control group (P < 0.05). After treatment, the TLR4 level in the observation group was lower than that of the control group, and the level of TGF-ß in the observation group was higher than that of the control group (P < 0.05). Conclusion: Compared with arthroscopic surgery alone, combined with modified Duhuo Jisheng Decoction can better alleviate the clinical symptoms of patients with KOA, improve their bone metabolism, oxidative stress indicators, and serum TLR4 and TGF-ß 1 level, and reduce the inflammatory injury of knee joint.

Comparison between acupotomy and corticosteroid injection for patients diagnosed with different classifications of tennis elbow: a randomized control trial.

BACKGROUND: Tennis elbow has long been one of the most controversial subjects in orthopaedics. Many scholars thought the use of open or arthroscopic surgery was reserved for patients with refractory symptoms. Therapy with percutaneous acupotomy performed under local anaesthesia also removes degenerated tissue, releases strain, and therefore provides an alternative treatment option to surgical excision. METHODS: The aim of this single-blinded randomized control trial was to examine the long-term clinical effectiveness of a nonsurgical percutaneous release technique (acupotomy) and the current recommended treatment (steroid injection) in people diagnosed with a refractory tennis elbow. Ninety patients with refractory symptoms were included. The intervention period was 6 weeks. According to the classification, 38 patients had extra-articular tennis elbow, 36 patients had intraarticular tennis elbow, and 16 patients had mixed type tennis elbow. Forty-five patients were randomly assigned to treatment with percutaneous release by acupotomy according to their classified condition, and 45 patients were randomly assigned to treatment with steroid injection alone. The visual analogue scale (VAS), a tenderness assessment, a grip assessment, and the Nirschl staging system were used for outcome evaluation at pretreatment and the posttreatment timepoints from 12 to 48 weeks. RESULTS: During the first weeks, there were no differences observed between the groups. By 6, 24 and 48 weeks, significant differences were observed between the two groups. The acupotomy group scored significantly better in visual analogue scale score (VAS) of pain, tenderness during palpation, pain-free grip strength (PFGS) and Nirschl staging than the corticosteroid group. CONCLUSIONS: For patients with lateral epicondylitis, acupotomy is just as effective as corticosteroid injections in the short term (< 6 weeks). In the long term, acupotomy has greater efficacy and is associated with a lower rate of recurrence than corticosteroid injections in the management of lateral epicondylitis. TRIAL REGISTRATION: The National Health Commission announced the "ethical review measures for biomedical research involving people" in 2019, which was not mandatory in previous studies.

Are psychosocial variables, sleep characteristics or central pain processing prognostic factors for outcome following rotator cuff repair? A protocol for a prospective longitudinal cohort study.

INTRODUCTION: Prognosis following surgical rotator cuff repair (RCR) is often established through the assessment of non-modifiable biomedical factors such as tear size. This understates the complex nature of recovery following RCR. There is a need to identify modifiable psychosocial and sleep-related variables, and to find out whether changes in central pain processing influence prognosis after RCR. This will improve our knowledge on how to optimise recovery, using a holistic rehabilitation approach. METHODS AND ANALYSIS: This longitudinal study will analyse 141 participants undergoing usual care for first time RCR. Data will be collected 1-21 days preoperatively (T1), then 11-14 weeks (T2) and 12-14 months (T3) postoperatively. We will use mixed-effects linear regression to assess relationships between potential prognostic factors and our primary and secondary outcome measures-the Western Ontario Rotator Cuff Index; the Constant-Murley Score; the Subjective Shoulder Value; Maximal Pain (Numeric Rating Scale); and Quality of Life (European Quality of Life, 5 dimensions, 5 levels). Potential prognostic factors include: four psychosocial variables; pain catastrophising, perceived stress, injury perceptions and patients' expectations for RCR; sleep; and four factors related to central pain processing (central sensitisation inventory, temporal summation, cold hyperalgesia and pressure pain threshold). Intercorrelations will be assessed to determine the strength of relationships between all potential prognostic indicators.Our aim is to explore whether modifiable psychosocial factors, sleep-related variables and altered central pain processing are associated with outcomes pre-RCR and post-RCR and to identify them as potential prognostic factors. ETHICS AND DISSEMINATION: The results of the study will be disseminated at conferences such as the European Pain Congress. One or more manuscripts will be published in a peer-reviewed SCI-ranked journal. Findings will be reported in accordance with the STROBE statement and PROGRESS framework. Ethical approval is granted by the Ethical commission of Canton of Zurich, Switzerland, No: ID_2018-02089 TRIAL REGISTRATION NUMBER: NCT04946149.
