Application of multidisciplinary team-based integrated traditional Chinese medicine and Western medicine in rotator cuff injury patients undergoing arthroscopic surgery

BACKGROUND Arthroscopic rotator cuff repair is a common surgical treatment for rotator cuff injuries(RCIs).Although this procedure has certain clinical advantages,it requires rehabilitation management interventions to ensure therapeutic efficacy.AIM To investigate the effect of integrated traditional Chinese medicine and Western medicine(TCM-WM)under the multidisciplinary team(MDT)model on the postoperative recovery of patients undergoing arthroscopic surgery for RCIs.METHODS This study enrolled 100 patients who underwent arthroscopic rotator cuff repair for RCIs at the Seventh People’s Hospital of Shanghai University of Traditional Chinese Medicine between June 2021 and May 2024.They were divided into a control group(n=48)that received routine rehabilitation treatment and an experimental group(n=52)that received TCM-WM under the MDT model(e.g.,acupuncture,TCM traumatology and orthopedics,and rehabilitation).The results of the Constant–Murley Shoulder Score(CMS),Visual Analogue Scale(VAS),Shoulder Pain and Disability Index(SPADI),muscular strength evaluation,and shoulder range of motion(ROM)assessments were analyzed.RESULTS After treatment,the experimental group showed significantly higher CMS scores in terms of pain,functional activity,shoulder joint mobility,and muscular strength than the baseline and those of the control group.The experimental group also exhibited significantly lower VAS and SPADI scores than the baseline and those of the control group.In addition,the experimental group showed significantly enhanced muscular strength(forward flexor and external and internal rotator muscles)and shoulder ROM(forward flexion,abduction,and lateral abduction)after treatment compared with the control group.CONCLUSION TCM-WM under the MDT model improved shoulder joint function,relieved postoperative pain,promoted postoperative functional recovery,and facilitated the recovery of muscular strength and shoulder ROM in patients with RCIs who underwent arthroscopic rotator cuff repair.

Mid-term outcomes of microfragmented adipose tissue plus arthroscopic surgery for knee osteoarthritis:A randomized,activecontrol,multicenter clinical trial

BACKGROUND Osteoarthritis(OA)is the most prevalent form of degenerative whole-joint disease.Before the final option of knee replacement,arthroscopic surgery was the most widely used joint-preserving surgical treatment.Emerging regenerative therapies,such as those involving platelet-rich plasma,mesenchymal stem cells,and microfragmented adipose tissue(MFAT),have been pushed to the forefront of treatment to prevent the progression of OA.Currently,MFAT has been successfully applied to treat different types of orthopedic diseases.AIM To assess the efficacy and safety of MFAT with arthroscopic surgery in patients with knee OA(KOA).METHODS A randomized,multicenter study was conducted between June 2017 and November 2022 in 10 hospitals in Zhejiang,China.Overall,302 patients diagnosed with KOA(Kellgren-Lawrence grades 2-3)were randomized to the MFAT group(n=151,were administered MFAT following arthroscopic surgery),or the control group(n=151,were administered hyaluronic acid following arthroscopic surgery).The study outcomes were changes in the Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)score,the visual analog scale(VAS)score,the Lequesne index score,the Whole-Organ Magnetic Resonance Imaging Score(WORMS),and safety over a 24-mo period from baseline.RESULTS The changes in the WOMAC score(including the three subscale scores),VAS pain score,and Lequesne index score at the 24-mo mark were significantly different in the MFAT and control groups,as well as when comparing values at the posttreatment visit and those at baseline(P<0.001).The MFAT group consistently demonstrated significant decreases in the WOMAC pain scores and VAS scores at all follow-ups compared to the control group(P<0.05).Furthermore,the WOMAC stiffness score,WOMAC function score,and Lequesne index score differed significantly between the groups at 12 and 24 mo(P<0.05).However,no signicant between-group differences were observed in the WORMS at 24 mo(P=0.367).No serious adverse events occurred in both groups.CONCLUSION The MFAT injection combined with arthroscopic surgery treatment group showed better mid-term clinical outcomes compared to the control group,suggesting its efficacy as a therapeutic approach for patients with KOA.

Arthroscopic surgery for synovial chondroma of the subacromial bursa with non-traumatic shoulder subluxation complications:Two case reports

BACKGROUND Synovial chondromatosis is a disease originating from the synovium and characterized by the presence of metaplastic cartilaginous nodules in synovial cavities.The exact prevalence of synovial chondromatosis remains unknown,and the involvement of the shoulder joint is very rare.Synovial chondromatosis accompanied by subluxation of the humeral head without a history of trauma is rarely encountered,and to our knowledge,no published reports describe this condition.CASE SUMMARY We present two cases of synovial chondromatosis in the shoulder joint,accompanied by subluxation of the humeral head,in two arthroscopically managed adult patients.We performed arthroscopic labrum fixation and removal of the loose body from the shoulder joint.To identify primary and secondary categories,pathological analysis was arranged.Clinical and radiographic evaluations at the 1-mo follow-up were satisfactory.CONCLUSION The biomechanical function of the shoulder joint requires attention,especially following the detection of loose bodies,as observed with synovial chondroma occurring in rare sites.Arthroscopic management is successful in patients with synovial chondromatosis combined with shoulder subluxation.

Application of Tranexamic Acid in Shoulder Arthroscopic Surgery:A Randomised Controlled Trial

Objective To explore the optimal administration route of tranexamic acid(TXA)in shoulder arthroscopic surgery.Methods Patients undergoing arthroscopic rotator cuff repair were randomly divided into four groups:control group(without TXA treatment),intravenous group(TXA was intravenously administered 10 minutes before surgery),irrigation group(TXA was added to the irrigation fluid during subacromial decompression and acromioplasty),and intravenous plus irrigation group(TXA was applied both intravenously and via intra-articular irrigation).The primary outcome was visual clarity assessed with visual analog scale(VAS)score,and the secondary outcomes included irrigation fluid consumption and time to subacromial decompression and acromioplasty procedure.Results There were 134 patients enrolled in the study,including 33 in the control group,35 in the intravenous group,32 in the irrigation group,and 34 in the intravenous plus irrigation group.The median and interquartile range of VAS scores for the intravenous,irrigation,and intravenous plus irrigation groups were 2.70(2.50,2.86)(Z=-3.677,P=0.002),2.67(2.50,2.77)(Z=-3.058,P<0.001),and 2.91(2.75,3.00)(Z=-6.634,P<0.001),respectively,significantly higher than that of the control group[2.44(2.37,2.53)].Moreover,the control group consumed more irrigation fluid than the intravenous group,irrigation group,and intravenous plus irrigation group(all P<0.05).The intravenous plus irrigation group consumed less irrigation fluid than either the intravenous group or the irrigation group(both P<0.001).There was no difference in subacromial decompression and acromioplasty operative time among the four groups.Conclusion TXA applied both topically and systematically can improve intraoperative visual clarity,and the combined application is more effective.

Absorbable implants in sport medicine and arthroscopic surgery:A narrative review of recent development

Over the past two decades,advances in arthroscopic and minimally invasive surgical techniques have led to significant growth in sports medicine surgery.Implants such as suture anchors,interference screws,and endo-buttons are commonly used in these procedures.However,traditional implants made of metal or inert materials are not absorbable,leading to complications that affect treatment outcomes.To address this issue,absorbable materials with excellent mechanical properties,good biocompatibility,and controlled degradation rates have been developed and applied in clinical practice.These materials include absorbable polymers,absorbable bioceramics,and absorbable metals.In this paper,we will provide a comprehensive summary of these absorbable materials from the perspective of clinicians,and discuss their clinical applications and related research in sport medicine.

Effects of different positions on rehabilitation after rotator cuff repair under shoulder arthroscopy

Objective Shoulder arthroscopic rotator cuff tear repair is currently the main treatment for full-thickness rotator cuff tears,and postoperative rehabilitation training is essential.However,pain and limitation of activity during the rehabilitation process will lead to poor results.Hence,identifying rehabilitation approaches is crucial.This study aimed to compare patient's rehabilitation outcomes and experience between rehabilitation in the supine position and in the standing position.Methods This prospective study included patients diagnosed with full-thickness rotator cuff tears who underwent shoulder arthroscopic double-row rivet repair at Sir Run Run Shaw Hospital,Zhejiang University School of Medicine from March 2019 to September 2021.The patients were randomly assigned to the standing rehabilitation exercise group(group A)and the supine rehabilitation exercise group(group B).All patients were followed up for 6 months to record and compare the visual analog scale(VAS)scores,shoulder range of motion,and rehabilitation compliance.Results Altogether,86 patients participated in the study,of whom 79 patients completed the 6-month follow-up.Groups A and B had 39 and 40 patients,respectively.Before operation,the VAS score,forward flexion and extension angle,and abduction angle were comparable between groups A and B.After operation,the patients in groups A and B all experienced a significant improvement in the VAS score,forward flexion and extension angle,and abduction angle(p<0.05).In addition,patients in group B had better VAS score(4.58±0.87 vs.5.21±1.13,p=0.0068;2.15±0.66 vs.2.51±0.51,p=0.0078;0.78±0.86 vs.1.33±0.81,p=0.0015),forward flexion and extension angle(109.30±2.87°vs.102.33±3.74°,p=0.0001;109.53±3.39°vs.104.18±2.76°,p=0.0001;125.22±6.05°vs.117.59±2.27°,p=0.0001),and abduction angle(91.78±2.77°vs.82.92±2.12°,p=0.0001;91.62±2.78°vs.82.82±1.45°,p=0.0001;109.48±3.37°vs.100.10±2.94°,p=0.0001)at 2 wk,6 wk and 6 m postoperatively.Conclusion After 6 months of follow-up,the patients who performed rehabilitation exercises in the supine position achieved better rehabilitation outcomes than those who performed rehabilitation exercises while standing.

Efficacy of mild moxibustion combined with surgery for meniscal injury and its effect on TGF-β1 and PDGF levels in the fluid of knee joint

Objective To observe the efficacy of mild moxibustion combined with arthroscopic meniscal repair in the treatment of meniscal injury and to explore its action mechanism.Methods Ninety-eight patients with meniscal injury were divided into a surgery group and a moxibustion plus surgery group by the random number table method,with 49 cases in each group.Both groups received arthroscopic meniscal repair,and the moxibustion plus surgery group was treated with add-on mild moxibustion.The Lysholm score,visual analog scale(VAS)score,and mobility of the affected knee were measured before and after treatment,and transforming growth factor(TGF)-β1 and platelet-derived growth factor(PDGF)levels were measured in the fluid of the affected knee joint.The healing of the meniscus was recorded at a follow-up visit 3 months after the surgery.Results After treatment,the Lysholm score increased,the VAS score decreased in both groups,and the intra-group differences in both groups were statistically significant(P<0.05).The Lysholm score was higher in the moxibustion plus surgery group than in the surgery group,and the VAS score was lower in the moxibustion plus surgery group than in the surgery group.The differences between groups in both scores were statistically significant(P<0.05).The mobility of the affected knee joint increased in both groups(P<0.05),and it was greater in the moxibustion plus surgery group than in the surgery group(P<0.05).When compared with pretreatment,the levels of TGF-β1 and PDGF in the fluid of the knee joint increased in both groups(P<0.05),and the levels of TGF-β1 and PDGF in the fluid of the affected knee joint were higher in the moxibustion plus surgery group than in the surgery group(P<0.05).The healing of the meniscus in the moxibustion plus surgery group was significantly better than that in the surgery group at the follow-up visit 3 months after the surgery(P<0.05).Conclusion The effect of mild moxibustion combined with arthroscopic meniscal repair is better than the surgery alone in improving knee function,relieving pain,increasing mobility of the affected knee,and promoting meniscal healing,which may be related to the up-regulation of TGF-β1 and PDGF levels in the fluid of knee joint.

Anatomic double-bundle anterior cruciate ligament reconstruction

Objective： To retrospectively evaluate the early results of anatomic double-bundle anterior cruci- ate ligament （ACL） reconstruction and compare with the results of native ACL of the contralateral knee. Methods： The results of a consecutive series of 118 patients receiving arthroscopic ACL reconstruction were evaluated. Eight patients were lost to the latest follow-up, leaving a total of 110 patients available for study within at least 3 years＇ clinical follow-up. Among them, 63 patients underwent postoperative MRI and CT scan, as well as clini- cal evaluation. Results： After reconstruction, the knees were stable and pain-free. Mean postoperative Lysholm score was 95.54 in 110 patients after 3 years. CT and MRI assessment showed that the reconstruction centered in the femoral footprint of ACL （n=63）. The sagittal ACL angle in the reconstructed ACL （52.16°±2.45°） was much close to that in the contralat- eral intact ACL （51.31 °±2.18°, P〉0.05）. By ACL-Blumensaat line angle analysis, there was no difference between doublebundle reconstructed knees and their contralateral normal knees （4.67°±0.43° vs. 4.62°±＊0.60°, P〉0.05）. Conclusion： Anatomic double-bundle ACL reconstruction can place grafts more precisely in the anatomic foot- print of the ACL and better restore knee kinematics.
