RESUMO
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.
RESUMO
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.

OBJECTIVE@#To investigate the efficacy and clinical results of total internal protection technique in anterior cruciate ligament reconstruction.@*METHODS@#A total of 56 patients undergoing anterior cruciate ligament reconstruction treated from January 2018 to December 2019 were selected. According to the different surgical methods, they were divided into total internal reconstruction group and standard bone tunnel group. There were 21 patients in the total internal reconstruction group, including 15 males and 6 females, aged from 20 to 48 with an average of (35.6±6.7) years old, and 35 patients in the standard tibial tunnel group, including 26 males and 9 females, aged 22 to 51 years old with an average of (33.7±9.6) years old. Preoperative examination of Lachman test was positive, magnetic resonance indicated anterior cruciate ligament rupture. There were no significant differences between the two groups in age, sex, body mass index, time from injury to ACL reconstruction, combined meniscus injury and operation method, operation time, ligament diameter, ligament length and other general information. Postoperative evaluation included operation duration, length and diameter of transplanted tendon after braid. International Knee Documentation Committee (IKDC) score, Lysholm score, Tegner score and perioperative complications 2 years after surgery.@*RESULTS@#Both groups were followed up, ranging from 24 to 30 months with an average of (26.9±3.4) months. Postoperative incision healing was good, and no failure or joint infection occurred at the last follow-up. There was no statistically significant difference between the two groups in IKDC score, Lysholm score and Tegner score before, 1 year and 2 years after surgery. However, IKDC score, Lysholm score and Tegner score at 1 year and 2 years after surgery.@*CONCLUSION@#The same postoperative function and stability of knee joint can be obtained by both the residual whole technique and the standardized reconstruction technique. In the residual whole group, only the semitendinosus muscle is taken, and the femoral thin muscle is retained, with greater tibial bone mass preserved, which is safe and effective in clinical practice.

Objective To analyze the factors associated with pain after arthroscopic rotator cuff bridge suture.Methods According to the inclusion and exclusion criteria,the data of 112 patients with unilateral rotator cuff injury who received arthroscopic bridge suture in our department were collected and were investigated in the form of telephone follow-up.In this study,SPSS 23.0 was used to input data and conduct statistical analysis.Logistic regression analysis was used to analyze the correlation between the above influencing factors and postoperative pain.Results A total of 112 patients were included for statistical analysis,single factor analysis revealed,including course of disease,smoking history,preoperative University of California,Los Angeles(UCLA)score,Constant score,numeric rating scale(NRS),size of rotator cuff tear,whether it was full-thickness tear and degree of tendon retraction might be related to postoperative pain(P<0.05).The age,gender,body mass index(BMI),drinking history,diabetes and hypertension were not related to postoperative pain(P>0.05).Multiple linear regression analysis concluded that there were four factors related to postoperative pain,and the correlation degree was preoperative NRS,preoperative UCLA score,tear size and smoking history.Conclusion The causes of postoperative pain after arthroscopic rotator cauff repair are complex and diverse.Analyzing the cause of postoperative pain can effectively reduce the pain of patients and promote the recovery of shoulder joint function.
RESUMO
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.
RESUMO
BACKGROUND:Transposition of the long head of biceps tendon is a commonly surgical method for massive rotator cuff tears.Currently,there are a few reports on the clinical efficacy of the transposition of the long head of biceps tendon and there is no consensus on the influencing factors for retearing. OBJECTIVE:To observe the outcome of arthroscopic long head of the biceps tendon in the treatment of massive rotator cuff tear. METHODS:The clinical data of 28 patients with massive rotator cuff tears,aged(61.79±10.50)years,admitted at Jiangsu Province Hospital of Chinese Medicine from March 2019 to May 2022 were retrospectively analyzed.All patients underwent arthroscopic long head of the biceps tendon.Patients were assessed for visual analog scale scores,University of California at Los Angeles scores,American Shoulder and Elbow Surgeons scores,Constant-Murley scores,and shoulder range of motion before and 1 year after operation.MRI of the shoulder joint was performed for observing the integrity of the repaired structure at 1 year after operation.Twenty-three patients(5 of 28 lost to follow-up)were categorized into the intact tendon group(n=18)and the tendon retear group(n=5)according to the Sugaya typing at 1 year after operation;the patients were divided into the normal group(n=8),the degeneration group(n=9),and the partial tear group(n=6)according to the intraoperative quality of the long head of the biceps tendon.Differences in the above indexes were compared between groups. RESULTS AND CONCLUSION:When followed up at 1 year after surgery,the range of motion,visual analog scale scores,University of California at Los Angeles scores,American Shoulder and Elbow Surgeons scores,Constant-Murley scores of the shoulder were significantly improved compared with preoperative data(P<0.05).There was a significant difference in Goutellier grading between intact tendon and tendon retear groups(P<0.05),while no significant difference was observed in the other influencing factors(P>0.05).There were no significant differences in visual analog scale scores,University of California at Los Angeles scores,American Shoulder and Elbow Surgeons scores,Constant-Murley scores,and shoulder range of motion at 1 year after operation among the normal,degeneration,and partial tear groups(P>0.05).MRI findings indicated that the sutured tendon healed well in 18 patients,with a healing rate of 78%.Arthroscopic long head of the biceps tendon for augmented repair can provide a reliable repair for massive rotator cuff tear that is refractory,significantly alleviate the pain of the shoulder joint,and restore the function of the shoulder joint.

RESUMO
Objective:To compare the clinical outcomes of arthroscopic external tension band fixation versus open reduction and internal fixation in the treatment of greater tubercle fracture of the humerus.Methods:A retrospective cohort study was conducted on 55 patients with greater tubercle fracture of the humerus admitted to Taizhou Hospital of Zhejiang Province from September 2019 to June 2022, including 24 males and 31 females, aged 26-80 years [(61.7±10.5)years]. Out of them, 35 patients treated with open reduction and internal fixation (open reduction group), and 20 patients were treated with external anchor tension band under arthroscopy (arthroscopy group). The operation time, and the Visual Analogue Scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score and shoulder active range of motion (anterior flexion, abduction and posterior extension) before operation, at 1 month after operation and at the last follow-up were compared between the two groups. Bone healing was observed in both groups at the last follow-up. Postoperative complications were compared between the two groups.Results:All the patients were followed up for 12-29 months [(16.9±4.0)months]. There was no significant difference in operation time between the two groups ( P>0.05). 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.
RESUMO
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.
RESUMO
Objective:To investigate the clinical effects of adjustable external fixation traction combined with arthroscopic microfracture in the treatment of osteochondral lesions of the talus (OLT).Methods:A retrospective study was conducted to analyze the data of 27 OLT patients who had been treated at Department of Orthopedics, Beijing Rehabilitation Hospital from May 2017 to March 2022. There were 16 males and 11 females, aged (32.4±7.2) years. Lesion site: 23 medial and 4 lateral cases; Hepple staging: 7 cases at stage Ⅰ, 15 cases at stage Ⅱ, and 5 cases at stage Ⅲ; disease duration: (10.6±3.3) months. All the patients were treated by adjustable external fixation traction combined with arthroscopic microfracture. Recorded were the patients' visual analogue scale (VAS) pain scores and American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores at 6 months and 12 months after surgery, levels of interleukin-1 (IL-1), interleukin-6 (IL-6) and tumour necrosis factor- α (TNF- α) at 1 month after surgery, lesion area at 12 months after surgery, and incidence of complications. Results:The follow-up time for this cohort was (16.2±6.7) months. The AOFAS score was (61.52±6.75) points before surgery, (84.15±5.56) points at 6 months after surgery and (95.67±4.30) points at 12 months after surgery. The VAS score was (5.88±1.02) points before surgery, (2.12±0.48) points at 6 months after surgery and (0.66±0.36) points at 12 months after surgery. The two-by-two comparisons between the 3 time points for the above items were statistically significant ( P<0.05). IL-1 was (32.37±6.64) pg/mL, IL-6 (34.04±7.12) pg/mL, and TNF- α (17.89±4.96) ng/L at 1 month after surgery in the 27 patients, all of which were significantly lower than their preoperative levels [(96.63±14.80) pg/mL, (102.33±20.42) pg/mL, and (54.48±9.33) ng/L] ( P<0.05). The lesion area was (28.66±6.52) mm 2 at 12 months after surgery, significantly smaller than the value before surgery [(128.52±11.32) mm 2] ( P<0.05). Infection at the adjustable external fixation needle track occurred in 1 patient and lower limb thrombosis in 2 patients. Conclusion:In the treatment of OLT, adjustable external fixation and traction combined with arthroscopic microfracture can achieve satisfactory results and improve symptoms for the patients.
RESUMO
Objective:To assess the clinical outcomes of hip arthroscopy in patients with concurrent femoroacetabular impingement (FAI) and subspine impingement (SSI).Methods:Data were retrospectively reviewed for patients with both FAI and SSI who underwent hip arthroscopy surgery from August 2021 to May 2022. A total of 23 patients (23 hips) followed up for more than 1 year, including 10 males and 13 females, 9 left hips and 14 right hips, with an average age of 31.3±4.6 years (range, 25-45 years). Subspine decompression by anterior inferior spine (AIIS) shaping for SSI was performed during hip arthroscopy in addition to labral repair and bony correction for FAI in the patients with concurrent FAI and SSI. Clinical outcomes were evaluated using preoperative and 1-year postoperative measures: lateral center-edge (LCE) angle, α angle on 45° Dunn view X-rays, maximum hip flexion angle, hip flexion and knee extension strength, visual analogue scale (VAS) for pain, modified Harris Hip Scores (mHHS), and International Hip Outcome Tool-12 (iHOT-12).Results:Of the 23 patients, 20 had type 2 AIIS and 3 had type 3 AIIS. At 1-year follow-up after surgery, there were significant improvements: LCE angle decreased (33.3°±6.1° to 31.7°±4.1°, t=1.076, P=0.288), α angle reduced (63.7°±8.5° to 50.0°±6.6°, t=6.116, P<0.001), hip flexion angle increased (107.4°±6.0° to 120.2°±4.4°, t=8.269, P<0.001), VAS scores decreased (4.0±1.1 to 1.0±1.1, t=9.591, P<0.001), mHHS improved (62.6±4.9 to 87.5±8.1, t=12.700, P<0.001), and iHOT-12 scores rose (51.4±4.9 to 75.7±7.7, t=12.593, P<0.001). There was no significant difference in the strength of hip flexion and knee extension between preoperative and follow-up ( t=0.930, P=0.357 and t=0.050, P=0.960, respectively). There were no reports of traction-related complications (such as skin necrosis and nerve paralysis), severe adverse events (such as femoral neck fractures, deep vein thrombosis in the lower limbs, intra-articular infections, ectopic ossification and hip instability), or the need for revision surgery. Conclusion:Subspine decompression by anterior inferior spine (AIIS) shaping for SSI during conventional hip arthroscopy is safe and effective, enhancing hip function and alleviating pain at 1-year follow-up without significant complications.

The average age was 32.5±8.2 years (range, 17-51 years). At the same time, 30 patients who underwent arthroscopic external release of the iliotibial band through the external surface of the iliotibial band (external iliotibial band group) were selected as control group, including 13 males and 17 females, aged 29.5±6.8 years (range, 11-45 years). The visual analogue scale (VAS), modified Harris hip score (mHHS), and gluteal muscle contracture disability scale (GDS) were compared between the two groups at preoperative, 6 months postoperative, and final follow-up.Results:All patients successfully completed the operation and were followed up for 17.5±3.3 months (range, 12-25 months). The VAS scores of the two groups at the last follow-up were lower than those before operation ( P<0.05). The mHHS scores before operation, 6 months after operation and at the last follow-up in the peritrochanteric space group were 76.5 (67.0, 85.5), 98.5 (94.8, 100.0) and 100.0 (97.0, 100.0), respectively, and those in the external iliotibial band group were 80.5 (70.0, 86.0), 100.0 (96.0, 100.0) and 100.0 (99.5, 100.0). The differences in mHHS scores between the two groups were statistically significant for intragroup comparisons ( P<0.05); of these, 6 months postoperatively and at the last follow-up were greater than preoperatively, with statistically significant differences ( P<0.05); the differences at 6 months postoperatively and at the last follow-up were not statistically significant ( P>0.05). There was no significant difference in mHHS scores between groups at different time points ( P>0.05). The GDS before operation, at 6 months after operation and at the last follow-up were 47.0 (35.8, 64.5), 90.0 (81.0, 94.0) and 93.5 (89.8, 98.0) in the peritrochanteric space group, and 51.0 (38.0, 64.5), 50.0 (81.0, 94.0) and 93.5 (89.8, 98.0) in the external iliotibial band group, respectively. The differences in GDS between the two groups were statistically significant for intragroup comparisons ( P< 0.05); of these, 6 months postoperatively and at the last follow-up were greater than preoperatively, with statistically significant differences ( P<0.05); the differences at 6 months postoperatively and at the last follow-up were not statistically significant ( P>0.05). There was no significant difference in GDS between groups at different time points ( P>0.05). Conclusion:Arthroscopic transverse release of the iliotibial band through peritrochanteric space for the treatment of external snapping hip can effectively reduce hip pain and improve hip function, with satisfactory clinical results, and can be used as an alternative treatment to transverse release through the external surface of the iliotibial band.
RESUMO
Objective:To analyze the clinic effects of arthroscopic partial trapeziectomy and suture button suspensionplasty in the treatment of first carpometacarpal joint (CMCJ) Eaton stage II/III arthrosis.Methods:A retrospective study was conducted on a total of 15 cases (16 hands) of patients including 5 males (1 bilateral) and 10 females with CMCJ stage II/III arthrosis who underwent surgical treatment at the first affiliated hospital of Shenzhen university from January 2020 to June 2022, with mean age of 56.7±6.4 years (range, 46-75 years). The duration from pain to treatment was 7.8±3.2 months (range, 4-14 months). X-ray showed narrowing of CMCJ with osteophytes and distal radial subluxation. All the patients were treated with arthroscopic partial trapeziectomy and suture button suspensionplasty. The preoperative and last postoperative follow-up radiographs, visual analogue scale (VAS), thumb's Kapandji scores, disabilies of the arm, shoulder, and hand (DASH) scores, grip and pinch strength and time to return to work were compared.Results:All cases were followed up for 19.6±6.3 months (range, 11-36 months). The postoperative X-ray showed all the CMCJs were reduced with a normal height of first metacarpal. The mean time for patients to return to their daily activities was 18.69±3.70 d and the mean time to return to work was 24.63±4.91 d. The average VAS score decreased from 6.56±1.15 preoperatively to 1.00 (0.75, 1.25). The preoperative Kapandji's score was 8.00±0.82 and the postoperative Kapandji's score was 8.00 (7.25, 9.00). The average DASH values improved from 24.06±3.19 to 4.00 (3.00, 5.00). The were significant differences except for Kapandji score ( Z=-4.905, P<0.001; Z=-0.121, P=0.905; Z=-4.846, P<0.001). The mean grip and pinch strength showed improvement from an average of 16.4 (14.13, 18.68) kg and 1.70±0.35 kg to 26.14±3.27 kg and 3.58±0.91 kg with significant difference ( Z=-4.617, P<0.001; t=-7.669, P<0.001). Conclusion:Arthroscopic partial trapeziectomy and suture button suspensionplasty is a minimally invasive surgery for the treatment of first CMCJ Eaton stage II/III arthrosis. By this technique, the patients' existing instability and pain problems can be solved.
RESUMO
This study reports a case of pachydermoperiostosis combined with posterior cruciate ligament femoral insertion avulsion fracture. The avulsion fracture was treated by arthroscopic surgery of suspension fixation. The symptom of the pachydermoperiostosis was relieved by non-steroidal anti-inflammatory drugs. Literature search and review were carried out by searching the key words of ("pachydermoperiostosis" OR "primary hypertrophic osteoarthropathy" OR "Touraine-solente-gole syndrome") OR ("posterior cruciate ligament" AND "avulsion fracture"). This patient was confirmed to be the first case reported suffering both diseases mentioned above. For the search results, there were 14 articles on posterior cruciate ligament femoral insertion avulsion fracture and 7 articles on pachydermoperiostosis. This study focused on the impact of pachydermoperiostosis on bone quality, possible factors for the avulsion fracture, and the advantages of arthroscopic surgery. Pachydermoperiostosis is a rare autosomal recessive disease. The incidence of posterior cruciate ligament femoral insertion avulsion fracture is extremely low. It is a seriously sports injury affecting the stability of the knee joint. Standardized surgical treatment can help patients obtain a satisfactory clinical outcome.
RESUMO
Objective:To explore the feasibility and effect of applying spherical fitting technology in CT three-dimensional reconstruction in preoperative planning of the resection range of Cam-type femoral acetabular impingement (FAI).Methods:46 Cam-type FAI patients who underwent arthroscopic femoroplasty in the Department of Sports Medicine in the Third Affiliated Hospital of Southern Medical University from July 2020 to June 2022 were enrolled in the spherical fitting group, including 26 females and 20 males, with an average age of 38.4±15.2 years (range of 24-53 years). The preoperative planning was performed using spherical fitting technology in CT three-dimensional reconstruction. Another 42 Cam-type FAI patients who underwent arthroscopic femoroplasty from July 2018 to June 2020 were enrolled in the observation group, including 25 females and 17 males, with an average age of 43.6±18.4 years (range 24-61 years). The preoperative planning was performed using CT three-dimensional reconstruction observation method. This study evaluated the impact of femoroplasty planned by spherical fitting technique on patients' prognosis though comparing the differences of postoperative α angle, femoral head-neck offset ratio, modified Harris hip score (mHHS), and visual analog score (VAS) at 3, 6, 9, and 12 months between two groups.Results:The average follow-up time was 11.8±0.6 months in spherical fitting group and 11.3±0.8 months in observation group. There was no significant difference regarding α angle, femoral head-neck offset ratio, mHHS, and VAS between two groups preoperatively ( P>0.05). The mHHS in two groups increased gradually, while VAS decreased sequentially at 3, 6, 9, and 12 months postoperatively. The postoperative mHHS and VAS were significantly better than those before surgery ( P<0.05). The mHHS was 83.2±14.8 vs. 70.5±11.2 in spherical fitting group and observation group at the followup of 9 months with significant difference ( t=4.471, P=0.007). It was 85.7±13.3 vs. 73.2±12.5 at the followup of 12 months with significant difference ( t=4.596, P=0.008). No significant difference was found in α angle, femoral head-neck offset ratio or mHHS at 3 and 6 months postoperatively ( P>0.05), and no significant difference was found in VAS at 3, 6, 9, and 12 months postoperatively between two groups. Conclusion:The spherical fitting technology in CT three-dimensional reconstruction could assist surgeons with planning of the resection range of Cam deformity preoperatively, and achieve a smooth progress of arthroscopic femoroplasty intraoperatively; after short term follow-up, we found that patients who underwent femoroplasty using this technology achieved satisfactory outcomes.
RESUMO
Objective:To investigate the clinical efficacy of arthroscopic surgery for the treatment of femoral acetabular impingement (FAI) in athletes.Methods:A total of 18 FAI athletes (athlete group) who underwent hip arthroscopy in the Department of Sports Medicine, Peking University Third Hospital from April 2014 to June 2021 were retrospectively analyzed, including 12 males and 6 females, aged 20.44±3.45 years (range, 15-27 years). According to gender, age, body mass index and follow-up time, 36 non-athlete FAI patients (non-athlete group) were matched at a ratio of 1∶2 by propensity score matching method. There were 18 males and 18 females, aged 20.81±4.68 years (range 14-31 years). The hip pain visual analogue scale (VAS), modified Harris hip score (mHHS), hip outcome score-activity of daily living scale (HOS-ADL) and hip outcome score-sports scale (HOS-SS) scores were compared between the two groups before and after surgery. The minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS) were also compared between the two groups.Results:All patients successfully completed the surgery and were followed up for 33.56±19.20 months (range, 24-77 months). The VAS score at the last follow-up decreased from 6.22±1.52 points before surgery to 1.28±1.67 points in the athletes group, and decreased from 6.28±1.37 points before surgery to 1.67±1.69 points in the non-athletes group. There was no significant difference between the two groups ( P>0.05). The mHHS score at the last follow-up increased from 65.53±12.90 points before surgery to 92.28±13.59 points in the athletes group, and increased from 61.01±11.96 points before surgery to 86.82±11.98 points in the non-athletes group. There was no significant difference between the two groups ( P>0.05). The HOS-ADL score at the last follow-up increased from 72.77±18.86 points before surgery to 94.00±11.36 points in the athletes group, and increased from 70.35±13.12 points before surgery to 90.78±9.36 points in non-athletes group. There was no significant difference between the two groups ( P>0.05). The HOS-SS score at the last follow-up increased from 49.77±22.93 points before surgery to 87.28±17.62 points in the athletes group, and increased from 44.08±19.66 before surgery to 72.57±20.16 in the non-athletes group. The HOS-SS scores in the athletes group at the last follow-up were higher than those in the non-athletes group ( P<0.05). Furthermore, 61% (11/18) in the athletes group achieved MCID in HOS-ADL after surgery, which was lower than the non-athletes group's 81% (31/36), with a statistically significant difference (χ 2=4.339, P=0.037). Conclusion:Hip arthroscopy in the treatment of FAI in athletes can achieve satisfactory pain relief and motor function.
RESUMO
Objective:To compare the short-term effect of the arthroscopic reconstruction of anterior cruciate ligament (ACL) by femoral tunnel positioning through the tendon incision (TI) technique and anteromedial (AM) technique.Methods:Between December 2015 and March 2017, 176 patients with ACL injuries underwent arthroscopic ACL reconstruction at the First Affiliated Hospital of USTC were analyzed. According to the method of localization of femoral tunnel, they were divided into two groups: TI group (localization of femoral tunnel by TI for reconstruction of ACL) and AM group (localization of femoral tunnel by AM for reconstruction of ACL). There were 87 patients in the TI group (63 males and 24 females) with an age of 32.8±9.4 years (range, 19-51 years) and a body mass index (BMI) of 24.8±6.3 kg/m 2 (range, 18.1-31.7 kg/m 2), including 9 obese patients (BMI>28 kg/m 2). There were 89 patients in the AM group (59 males and 30 females) with an age of 36.7±13.0 years (range, 17-56 years) and a BMI of 25.7±5.8 kg/m 2 (range, 18.9-31.6 kg/m 2), including 11 obese patients. To evaluate whether the drill was in contact with the articular surface of the medial condyle of the femur, whether the anterior angle of the medial meniscus was damaged, the sagittal and coronal angles of the femoral tunnel and the total length of the femoral tunnel. The anterior drawer test, Lachmann test, pivot shift test, knee flexion angle (KFA), Lysholm score, International Knee Documentation Committee (IKDC) score and the incidence of postoperative complications were compared between the two groups. At the same time, the time of taking out tendon, operation time, hospital stay and recovery time were compared between two groups of obese people. Results:In the TI group, the guide pin could reach all areas of the medial wall of the lateral femoral condyle from the inferior cartilage edge to the top of the intercondylar fossa, the drill bit had no contact with the medial femoral condyle (MFC), and the anterior angle of the medial meniscus was not damaged. In AM Group, 3 cases of MFC and 1 case of anterior horn of medial meniscus were injured in order to get the best position of femoral tunnel. The angle of femoral tunnel in sagittal plane (50.2°±3.2°) and coronal plane (46.1°±5.8°) in experimental group was notably larger than that in control group (45.6°±5.4°, 38.3°±4.7°), the difference was statistically significant ( P<0.05). However, there was no significant difference in the length of femoral tunnel between the two groups (38.2±3.2 mm and 37.7±2.5 mm, P>0.05). All patients were followed up for an average of 8.3±2.1 (range, 3-12) months. The positive rates of anterior drawer test, Lachmann test and pivot shift test were not significantly different between the two groups at 3, 6, 9 and 12 months after operation ( P>0.05). The KFA, Lysholm and IKDC scores in both groups were significantly increased after operation ( P<0.05), but there was no significant difference of above indexes between the two groups ( P>0.05). The overall complication rate in AM group (14.6%, 13/89) was significantly higher than that in TI group (6.9%, 6/87), the difference was statistically significant ( P<0.05). Additionally, the tendon harvesting (15.0±0.2 min vs. 26.0±0.2 min, P<0.05) and operation time (2.0±0.3 h vs. 3.0±0.4 h, P<0.05) were significantly shortened among obese patients in experimental group compared with those in control group. Conclusion:The TI technique demonstrates comparable effectiveness to the AM technique in ACL reconstruction through femoral tunnel positioning, with the added advantage of safer femoral tunnel localization. This approach minimizes the risk of iatrogenic injuries to the articular cartilage of the medial condyle of the femur and the anterior horn of the medial meniscus. Furthermore, the TI technique reduces tendon removal time, particularly beneficial for obese patients.
RESUMO
Objective:To investigate the indications and effects of arthroscopic all-inside reconstruction in the treatment of isolated posterior cruciate ligament (PCL) injury.Methods:A retrospective analysis was performed on 47 patients with isolated PCL injury, who underwent arthroscopic all-inside reconstruction in the Third Medical Center of the PLA General Hospital from January 2016 to January 2020. There were 39 males and 8 females, aged 27.14±7.70 years old (range 16-40 years old). The preoperative kneeling-position stress X-ray showed that the degree of tibial posterior displacement was 8-10 mm, which was a complete and isolated Grade II PCL injury. The tibial and femoral tunnels were created through posterior-medial, anteromedial, and anterolateral portals, while the lateral portal to the medial femoral condyle was enlarged to position the tibial tunnel and protect the anterior cruciate ligament. The autologous graft tendon was pulled through the femoral and tibial tunnels secured with an adjustable loop plate. The efficacy was evaluated by evaluating and comparing preoperative and postoperative Lachman test, posterior drawer test, knee range of motion and relaxation, pain visual analogue scale (VAS) and Lysholm score.Results:43 patients were followed up for 35.21±3.88 months (range 12-40 months). The symptoms of knee instability all improved after surgery. At the follow-up of 1 year after surgery, 41 (95%) and 40 (93%) patients showed normal or I-degree laxity in Lachman test and posterior drawer test, respectively. The active range of motion and passive flexion of the knee joint were increased to 90°-110° and 110°-130°, respectively. The Lysholm score was 86.44±4.08 at the first year of follow-up and 90.12±3.33 at the last follow-up with significant difference compared with pre-operations ( P<0.05). The VAS score was 2.07±0.94 at the first year of follow-up and 1.28±0.83 at the last follow-up with significant difference compared with pre-operations ( P<0.05). The Lysholm score and VAS were 90.12±3.33 and 1.28±0.83, which were significantly improved compared to 1-year-follow-up ( P<0.05). Conclusion:Routine kneeling stress X-rays can evaluate the degree of tibial posterior displacement in isolated PCL injuries. With tibial posterior displacement equal to or greater than 10 mm, surgical reconstruction was required. All-inside reconstruction of isolated PCL injury was a safe and minimally invasive surgery to improve symptoms and restore knee functions.
