Functional Outcomes Of Transtibial Pullout Technique Of Meniscal Root Repair

Objectives: This study aimed to evaluate the functional outcomes of the knee in patients undergoing meniscal root repair using transtibial pullout technique. Conducted as a prospective study, this research included 26 patients with meniscal root tears who were treatedMaterials and Methods: through arthroscopic repair. Follow-up assessments were carried out at 6 weeks, 3 months, and 6 months post-surgery. Functional outcomes were measured using the Visual Analog Scale (VAS) and the Lysholm Knee Score. The preoperative VAS score averaged 7.46. PostoperativeResults: VAS scores were 4.23 at 6 weeks, 3.12 at 3 months, and 1.19 at 6 months. These reductions were statistically signi?cant with a p-value < 0.001. Most patients experienced excellent improvements in the range of motion, with the overall enhancement being statistically signi?cant (p-value < 0.001). The Lysholm Knee Scores also showed signi?cant improvement: the preoperative score was 68.52, which increased to 81.72 at 6 weeks, 85.72 at 3 months, and 92.23 at 6 months postoperatively. These improvements were statistically signi?cant with a p-value < 0.001. Conclusion: The study found that sports-related injuries were more common, particularly among young males. Post-meniscus repair, a good range of motion can be restored if an appropriate postoperative physiotherapy rehabilitation protocol is followed, allowing many patients to regain knee function.

Comparison of the effects of two concentrations of adrenaline (0.33 mg/l versus 1 mg/l) in the irrigation serum for arthroscopic shoulder surgery: protocol of a randomized controlled trial

Background: Controlling bleeding during arthroscopic shoulder surgery helps improve the clarity of the arthroscopic visual field. Adrenaline is considered an effective and safe method to reduce bleeding. Two doses of adrenaline (0.33 mg/l and 1 mg/l) have been evaluated in the literature, but never against each other. Methods: This prospective, double-blind, randomized controlled trial will study the clarity of the visual field using a numerical scale (NS) during rotator cuff surgery on 180 patients across 5 centres. The secondary objectives include: the duration of the operation, volume of saline used, increase in baseline pressure, number of arthropump hyperpressures, mean systolic blood pressure and heart rate, as well as sudden variability. Results: Among the 154 patients in the Clinical Trial Group, 70/154 (45%) continued to have proteinuria, while 84/154 (55%) had no proteinuria (remission) compared to 41 (28%) in remission and 104 (72%) with continued proteinuria in the Usual Care group (p<0.001). Conclusions: This study aims to determine which of the two dosages previously studied in the literature (0.33 mg/l versus 1 mg/l) provides better clarity. Trial Registration Number: 2021-A02773-38.

Analysis of the Accuracy of CAM-type Deformity Resection on a Low-cost Arthroscopic Simulator in a Training Scenario / Análise da acurácia da ressecção de deformidades tipo CAME em simulador artroscópico de baixo custo em um cenário de treinamento

Abstract Objective To evaluate surgeons' performance in resecting CAM-type deformities using a realistic arthroscopic surgery simulator. Methods An arthroscopic simulator was created using low-cost materials with the help of a GTMax Core A1 3D printer and the programs Invesalius and Meshmixer 2017, which were used to develop femoral head parts in ABS material, with the presence of a CAM-type deformity, to mimic a femoroacetabular impact situation. After the operations were performed by 16 surgeons, the femurs were compared to a previous model with deformity and another without, using Cloudcompare, and parameters such as the volumetric difference between the operated femurs, with and without deformity, the minimum and maximum distance between them, the percentage of the deformity resected, the estimated time for total resection of the deformity, as well as a qualitative analysis based on the images and graphs provided by the program representing the areas of the parts resected, were evaluated at the end. Results The average resection speed was 34.66 mm3/min (SD = 46 mm3/min, max = 147.33; min = −2.66). The average resection rate was 26.2% (SD = 34.7%, max = 111; min = −2). Qualitative analysis showed hyporesection of deformities and sometimes hyperresection of nondeformed areas. The simulator was highly rated by the surgeons, with a tactile sensation very similar to real surgery, according to them. Conclusion Arthroscopic simulators have proved very useful in training less experienced surgeons.

Resumo Objetivo Avaliar o desempenho de cirurgiões na ressecção de deformidades tipo CAME fazendo uso de um simulador realista de cirurgia artroscópica. Métodos Um simulador artroscópico foi criado a partir de materiais de baixo custo com auxílio de uma impressora 3D GTMax Core A1 e dos programas Invesalius e Meshmixer 2017, que foram utilizados para criar peças de cabeça de fêmur em material ABS, com a presença de uma deformidade tipo CAME, a fim de mimetizar uma situação de impacto femoroacetabular. Após as operações serem realizadas por 16 cirurgiões, os fêmures foram comparados a um modelo prévio com e outro sem deformidade pelo programa Cloudcompare, sendo avaliados ao final parâmetros como diferença volumétrica entre os fêmures operados, com e sem deformidade, distância mínima e máxima entre eles, porcentagem da deformidade ressecada, tempo estimado para ressecção total da deformidade, além de uma análise qualitativa feita com base nas imagens e gráficos fornecidos pelo programa representando as áreas das peças efetivamente ressecadas. Resultados A velocidade média de resseção foi de 34,66mm3/minuto (DP = 46 mm3/min, max = 147,33 mm3/min; min = −2,66 mm3/min). A média de ressecção obtida foi de 26,2% (DP = 34,7%, max = 111%; min = −2%). A análise qualitativa demonstrou uma hiporresecção das deformidades e, por vezes, hiperresecção de áreas não deformadas. O simulador foi muito bem avaliado pelos cirurgiões, tendo uma sensação tátil bem semelhante à cirurgia real segundo os mesmos. Conclusão Simuladores artroscópicos se mostraram muito úteis no treinamento de cirurgiões menos experientes.

Updates in the Treatment of Knee Osteoarthritis / Atualizações no tratamento da osteoartrite de joelho

Abstract Knee osteoarthritis (OA) is an inflammatory and degenerative condition resulting in articular cartilage destruction and functional loss. Its prevalence has grown considerably due to increased life expectancy and obesity, and its diagnosis relies on evaluation, medical examination, and confirmation by supplementary radiographic images. Knee OA is multifactorial and influenced by several local, systemic, and external aspects. In addition, its progress and therapeutic responses highly depend on the characteristics of each subject. The initial recommendation is drug treatment and alternative therapies to improve quality of life. However, if these treatments are unsuccessful, one must consider surgical treatment. Surgical options include arthroscopies, osteotomies, and partial and total arthroplasties, while non-surgical treatments include medications and alternative therapies such as infiltrations, acupuncture, and physical exercise. It is worth highlighting that biomarkers can be a significant strategy for early disease detection, assessment of disease activity, prediction of prognosis, and monitoring a better response to therapy. Nevertheless, this topic must be the focus of further research to confirm its findings.

Resumo A osteoartrite (OA) do joelho é uma doença inflamatória e degenerativa que ocasiona a destruição da cartilagem articular e leva à perda de funções. Sua prevalência vem crescendo consideravelmente devido ao aumento da expectativa de vida e da obesidade, e o diagnóstico pode ser feito por meio de avaliação e exames médicos, e é confirmado em imagens radiográficas complementares. Uma condição multifatorial, a OA do joelho pode ser influenciada por diversos aspectos locais, sistêmicos e externos; além disso, a sua evolução e as respostas aos tratamentos dependem muito das características de cada indivíduo. Inicialmente, recomenda-se proceder a um tratamento medicamentoso e a terapias alternativas que melhorem a qualidade de vida do paciente; mas, a partir do momento em que se verifica que tais terapias não estão proporcionando resultados satisfatórios, um tratamento cirúrgico deve ser considerado. Entre os tratamentos cirúrgicos, as artroscopias, as osteotomias e as artroplastias parciais e totais são destacadas; os métodos não cirúrgicos incluem o uso de medicamentos e de terapias alternativas, como infiltrações, acupuntura e prática de exercícios físicos. Vale ressaltar ainda que a utilização de biomarcadores pode ser uma importante estratégia para detectar precocemente a doença, avaliar sua atividade, prever um prognóstico e monitorar uma melhor resposta à terapia; porém, esse tema ainda deve ser foco de mais estudos para que os seus resultados sejam comprovados.

Morphometry of the Suprascapular Notch and the Incidence of Ossification of Superior Transverse Scapular Ligament in an Adult Human Scapulae Bone of South Indian Population

Introduction: The scapulae of human bone bears suprascapular notch and the ligament in it undergoes ossification causing compression of the suprascapular nerve. The degree of ossification of transverse ligament of scapula helps to differentiate it from rotator cuff tear as to prevent muscle wasting and atrophy. Materials and Methods: A sample of 50 dry scapulae bone in the Anatomy department, Annapoorana Medical College & Hospitals, Salem was utilized. Based upon suprascapular notch shape, the scapulae were categorized into six varieties. The parameters such as Superior, Middle and Inferior transverse length, Notch depth was determined thrice by taking measurements with vernier caliper. The results were analysed by software SPSS (IBM) 25 version. Results: The findings revealed, the predominant type was Type III and Type I (24%) and least was Type VI (4%) with complete ossification of STSL. The mean MD in Type IV notch is 6.32±1.19mm where the depth was ultimately reduced compared to Type II, III, V notches. So, the depth of Type IV notch should be kept in mind to predict neuropathy as it may cause nerve compression. Conclusion: The current study helps clinicians be aware about variations in the morphometry of SSN while categorising the notch type causing neuropathy before performing any surgical intervention.

OBJECTIVE@#To investigate short-term effectiveness of arthroscopic repair via modified subacromial viewing portal (hereinafter referred to as modified viewing portal) in treatment of LafosseⅠsubscapularis tendon tears.@*METHODS@#A clinical data of 52 patients with LafosseⅠsubscapularis tendon tears, who underwent the arthroscopic repair via modified viewing portal between October 2020 and November 2022 and met the selective criteria, was retrospectively analyzed. There were 15 males and 37 females with an average age of 63.4 years (range, 41-76 years). Twelve patients had trauma history and the other 40 patients had no obvious inducement. The main clinical symptom was shoulder pain and the hug resistance tests were positive in all patients. The interval between symptom onset and admission ranged from 3 to 26 months (mean, 7.2 months). The shoulder pain and function were evaluated by visual analogue scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, and University of California Los Angeles (UCLA) score before operation and at 12 months after operation. The shoulder range of motion (ROM) of forward flexion, abduction, and external rotation and the internal rotation strength were measured before operation and at 3 and 12 months after operation. MRI was performed at 3-6 months after operation to assess the tendon healing and the structural integrity and tension of reattached tendon. Patient's satisfactions were calculated at last follow-up.@*RESULTS@#All incisions healed by first intention, no complication such as incision infection or nerve injury occurred. All patients were followed up 12-37 months (mean, 18.5 months). The VAS, UCLA, and ASES scores at 12 months after operation significantly improved when compared with those before operation ( P<0.05). The ROMs of abduction and forward flexion and the internal rotation strength at 3 and 12 months significantly improved when compared with those before operation ( P<0.05); and the ROMs at 12 months significantly improved compared to that at 3 months ( P<0.05). However, there was no significant difference ( P>0.05) in the ROM of external rotation at 3 months compared to that before operation; but the ROM at 12 months significantly improved compared to that before operation and at 3 months after operation ( P<0.05). Thirty-one patients underwent MRI at 3-6 months, of which 28 patients possessed intact structural integrity, good tendon tension and tendon healing; 3 patients underwent tendon re-tear. At last follow-up, 41 patients (78.8%) were very satisfied with the effectiveness, 7 were satisfied (13.5%), and 4 were dissatisfied (7.7%).@*CONCLUSION@#Arthroscopic repair via modified viewing portal for Lafosse Ⅰsubscapularis tendon tears, which can achieve the satisfactory visualization and working space, can obtain good short-term effectiveness with low overall re-tear risk.

There were no significant differences in the VAS score, ASES score, Constant-Murley score and shoulder active range of motion between the two groups before operation ( P>0.05). The VAS score of the arthroscopy group was 3(2, 3)points at 1 month after operation, which was significantly lower than that of the open reduction group [4(3, 4) points] ( P<0.01). No significant difference was found in the VAS score at the last follow-up between the two groups ( P>0.05).The ASES scores of the arthroscopy group were (70.6±4.2)points and (90.2±3.7)points at 1 month after operation and at the last follow-up respectively, which were significantly higher than those of the open reduction group [(64.7±6.4)points and (87.5±4.9)points respectively] ( P<0.05 or 0.01). There was no significant difference in the Constant-Murley score between the arthroscopy group [(71.8±4.3)points] and the open reduction group [(70.9±5.3)points] at 1 month after operation ( P>0.05), while the Constant-Murley score of the arthroscopy group was (94.1±3.1)points at the last follow-up, which was significantly higher than that of the open reduction group [(89.2±4.7)points] ( P<0.01). At 1 month after operation and at the last follow-up, ranges of motion of the anterior flexion, abduction and posterior extension were (52.7±12.3)° and (140.0±16.9)°, (57.4±8.6)° and (125.0±14.3)°, and 16(15, 19)° and 25(20, 30)° in the arthroscopy group respectively, which were significantly higher than those in the open reduction group [(42.2±5.2)° and (110.9±14.0)°, (52.8±6.0)° and (103.7±11.7)°, and 10(10, 20)° and 16(15, 25)° respectively] ( P<0.05 or 0.01). At the last follow-up, it was found that bony union was achieved in both groups. There were no obvious complications such as incision infection or joint stiffnessin both groups. In the open reduction group, 2 patients had internal fixation failure within 1-3 months after operation but was treated with revision operation; 6 patients developed shoulder stiffness at 3-6 months after operation but had outpatient rehabilitation. The incidence rate of postoperative complications in the arthroscopy group [0%(0/20)] was significantly lower than that in the open reduction group [23%(8/35)] ( P<0.05). Conclusion:Compared with open reduction and internal fixation with plates and screws, arthroscopic external anchor tension band fixation in the treatment of greater tuberosity fracture of the humerus has the advantages of earlier pain relief, better shoulder functional improvement, better recovery of shoulder mobility, and fewer complications.

Objective:To investigate the efficacy of arthroscopic superior capsular reconstruction using composite autologous patch graft combined with tenodesis of the long head of the biceps tendon in the treatment of irreparable massive rotator cuff tears (IMRCT).Methods:A retrospective case series study was performed on 11 IMRCT patients who were admitted to Affiliated Fuyang Hospital of Bengbu Medical University (Fuyang People′s Hospital) from May 2020 to June 2022, including 7 males and 4 females, aged 54-74 years [(62.6±7.3)years]. All the patients were treated with arthroscopic superior capsular reconstruction using composite patch graft combined with tenodesis of the long head of the biceps tendon. The Visual Analogue Scale (VAS), Acromiohumeral Distance (AHD), Constant-Murley score and University of California Los Angeles (UCLA) score and active range of motion of the shoulder joint before, at 6 months after surgery and at the last follow-up were compared. At the last follow-up, the integrity of reconstructed superior capsule and the long head of the biceps tendon was evaluated using MRI of the shoulder joint. Postoperative complications were observed.Results:All the patients were followed up for 13-39 months [16(13, 36)months]. The VAS score, AHD, Constant-Murley score, and UCLA score were 2(2, 3)points, (9.1±1.1)mm, (56.1±5.4)points, and (19.7±2.8)points respectively at 6 months after surgery, which were all significantly improved from those before surgery [6(5, 7)points, (5.1±1.2)mm, (37.9±2.2)points, and (11.8±1.2)points] ( P<0.05). The VAS score, AHD, Constant-Murley score, and UCLA score were 0(0, 1)points, (8.4±0.9)mm, (83.6±3.8)points, and (28.2±2.3)points respectively at the last follow-up, which were all significantly improved from those before surgery ( P<0.05). At the last follow-up, the VAS score or AHD were not significantly improved from those at 6 months after surgery ( P>0.05); Constant-Murley score and UCLA score were both significantly improved from those at 6 months after surgery ( P<0.05). At 6 months after surgery, shoulder active ranges of motion in forward flexion, abduction and external rotation were (134.6±13.5)°, (124.6±18.6)° and 45(40, 50)° respectively, which were all significantly improved compared with those before surgery [(63.2±36.1)°, (65.0±23.1)°, and [30(20, 40)°] ( P<0.05). At the last follow-up, shoulder active ranges of motion in forward flexion, abduction and external rotation were (144.1±12.6)°, (139.6±15.4)° and 60(45, 65)° respectively, which were all significantly improved compared with those before surgery ( P<0.05). There were no significant differences in active range of motion of the shoulder in forward flexion, abduction and external rotation between 6 months after surgery and the last follow-up ( P>0.05). At the last follow-up, MRI revealed integrity of the reconstructed superior joint capsule and the long head of the biceps tendon in 10 patients. One patient developed resorption of the greater tuberosity and 1 showed a partial tear of the supraspinatus tendon at 1 year after surgery. Conclusion:Arthroscopic superior capsular reconstruction using composite autologous patch graft combined with tenodesis of the long head of the biceps tendon can relieve shoulder pain, decrease upward displacement of the humerus head, improve the function and range of motion of the shoulder joint, and reduce complications in the treatment of IMRCT.

Comparison between portals for placement of anchors in shoulder instability / Comparação entre portais para colocação de âncoras na instabilidade do ombro

ABSTRACT Objective: to radiographically compare the effects of anchor positioning in the arthroscopic treatment of shoulder instability, in the 3- and 5-o'clock portals. Methods: retrospective study of 36 patients, operated by two shoulder surgeons at the Unimed BH hospital, between January 2013 and January 2018. Each surgeon used only one of either the 3- or the 5-o'clock portal. After postoperative radiographs we performed angle comparisons between the greatest glenoidal axis, the angle of anchor insertion and distance from the inferior pole. Results: the 5-o'clock portal provided better placement than its 3-o'clock counterpart, which allowed for greater orthogonality in relation to the glenoid rim (p < 0.05). Conclusion: the 5-o'clock portal allowed for better anchor placement than the 3 o'clock one. Level of Evidence II, Clinical Trial.

RESUMO Objetivo: Comparar radiograficamente o posicionamento das âncoras utilizadas no tratamento artroscópico da instabilidade do ombro, através dos portais de 3 ou 5 horas. Métodos: Avaliação retrospectivae de 36 pacientes, operados por dois cirurgiões de ombro do Hospital Unimed BH, entre janeiro de 2013 e janeiro de 2018. Cada cirurgião utilizou apenas uma das técnicas - portal de 3 ou 5 horas. As radiografias pós-operatórias foram avaliadas e comparadas a angulações entre o maior eixo da glenoide, o ângulo de inserção da âncora e a distância em relação ao polo inferior. Resultados: A utilização do portal de 5 horas propiciou a colocação mais adequada das âncoras em relação ao portal de 3 horas, permitindo o posicionamento mais ortogonal em relação à borda da glenoide (p < 0,05). Conclusão: A utilização do portal de 5 horas apresenta melhor posicionamento das âncoras quando comparado ao portal de 3 horas. Nível de evidência II, Ensaio Clínico.

Treatment of high ankle sprains with Suture-button elastic fixation assisted by arthroscopy / 中国组织工程研究

BACKGROUND:High ankle sprain is easily missed and leads to ankle dysfunction.Arthroscopy can detect hidden high ankle sprain.Suture-button elastic fixation can restore the biomechanical stability of the distal tibiofibular syndesmosis. OBJECTIVE:To explore the clinical efficacy of Suture-button elastic fixation for high ankle sprain under ankle arthroscopy. METHODS:A retrospective analysis was performed on 40 cases of high ankle sprain patients treated with Suture-button elastic fixation under ankle arthroscopy from August 2019 to August 2021 in the Department of Foot and Ankle Surgery,Wuhan Fourth Hospital.All patients underwent Suture-button elastic fixation.The American Orthopedic Foot and Ankle Society function score,Visual Analog Scale pain score,ankle range of motion,preoperative imaging data,and arthroscopic tibiofibular syndesmosis separation degree were recorded.Meislin criteria were used to evaluate the curative effect and postoperative complications were recorded. RESULTS AND CONCLUSION:(1)40 patients were followed up for 16-48 months after operation.(2)At the last follow-up,American Orthopedic Foot and Ankle Society score was(88.95±6.64 points).Visual Analog Scale score was(1.78±1.23 points).Ankle dorsiflexion range of motion was(33.50±5.79 degrees).Ankle plantarflexion range of motion was(34.50±5.97 degrees).There were statistically significant differences before and after surgery(P<0.05).(3)There was a low positive correlation between the radiographic separation index and the degree of arthroscopic separation(r=0.612,P<0.01).(4)The curative effect was evaluated by Meislin standard,with an excellent and good rate of 95%(38/40).Postoperative ankle joint pain was relieved,and ankle joint activities were significantly improved.(5)During the follow-up period,all patients had no nerve injury or incision infection.In 1 patient,the internal fixation was removed due to skin irritation and squatting sensation after operation.(6)It is concluded that Suture-button elastic fixation for high ankle sprain is effective under ankle arthroscopy in restoring ankle function and maintaining joint stability without the need for secondary removal,and it is worth clinical application.
