AMR Sign - An Arthroscopic S-shaped Fold Signifying Adequate Medial Meniscus Repair

@#Introduction: The preferred management of medial meniscus tears has notably moved from meniscectomies towards repair. With a higher volume of meniscal repairs being done all across the world with every passing day, the lack of an objective and definitive sign suggesting the adequacy of its repair is daunting. The purpose of our study was to introduce a unique and novel arthroscopic sign formed after adequate repair of the medial meniscus, the AMR (Adequacy of Medial meniscus Repair) sign. We hypothesised that it is not only the objective end point for repair, but can also form the indicator for excellent clinical, functional, and radiological outcome even in the long term. Materials and methods: This was a multicentric, prospective study initiated by the corresponding author, and the findings validated subsequently by the other authors. Overall, it included 804 patients of isolated medial meniscus tear operated with arthroscopic all-inside technique between January 2014 and December 2017. Patients were segregated into three groups based on whether an S-shaped curve in the free, inner edge of the medial meniscus sign was formed post-repair, lost after further tightening, or not formed upon subjective completion of repair. All the patients were followed-up and evaluated based of medial joint line tenderness, McMurray’s test for medial meniscus, IKDC score, WOMET score, and radiologically using an MRI at the terminal follow-up. Results: The mean terminal follow-up was 42.34±4.54 months. There was significant (p<0.01) improvement in all patients at the terminal follow-up post-surgery, irrespective of the group. The group in which AMR sign was formed and maintained showed a significantly better functional outcome on terminal follow-up as well as lower failure rates compared to the other two groups. Conclusion: AMR sign is an S-shaped fold at the inner, free edge of medial meniscus, formed after an adequate repair of isolated medial meniscus tear, as viewed on arthroscopy. It is an objective sign denoting regained integrity of the collagen architecture of the medial meniscus following repair. It is also a reliable indicator of excellent long term functional, clinical, and radiological outcome and also lower failure rates in patients after arthroscopic medial meniscus repair.

Delaminated Rotator Cuff Tear: Concurrent Concept and Treatment

Delaminated rotator cuff tear pertains to the horizontal split of the tendon substance. As reported previously, the presence of a delaminated tear and incidence of delaminated rotator cuff tear ranges from 38% to 92%. The different strain intensities applied across the rotator cuff tendon, and the shear stress between the bursal and articular layers seem to play a role in its pathogenesis. In a delaminated rotator cuff tear, the degree and direction of retraction between two layers differ, with accompanying intrasubstance cleavage. A surgeon therefore needs to consider and carefully evaluate the tear characteristics when repairing delaminated rotator cuff tear. Delaminated rotator cuff tear is considered to be a poor prognostic factor after rotator cuff repair, but numerous surgical repair techniques have been introduced and applied to resolve this problem. Recent literature has reported good clinical outcomes after delaminated rotator cuff repair.

Inestabilidad cronica lateral del tobillo: comparacion entre la reparacion de brostrom-gould y una tecnica artroscopica / Chronic Lateral Ankle Instability: Comparison Between Brostrom-Gould Repair And An Arthroscopic Technique

Introducción La inestabilidad crónica lateral del tobillo es una patología frecuente en las personas que sufren esguinces. El tratamiento inicial es conservador y de no funcionar se recomienda el tratamiento quirúrgico; la técnica descrita por Broström y modificada por Gould es la más utilizada, efectiva y reportada en la actualidad. Con el advenimiento de la cirugía artroscópica, uno de los autores (JBGG) ha desarrollado una técnica mínimamente invasiva que se ha utilizado en la unidad de pie desde hace 8 años. Este trabajo evalúa los resultados funcionales, de dolor y cicatrización de los pacientes tratados con la técnica Artroscópica y la técnica de Broström-Gould abierta. Materiales & Métodos Se evaluaron un total de 111 pacientes, 50 con la técnica abierta y 61 con técnica artroscópica, operados por inestabilidad lateral crónica del tobillo entre enero de 2004 y diciembre de 2011. Se utilizo la escala AOFAS de tobillo y retropié para la medición del dolor, función y alineación, y la escala EVA para la medición del dolor. Resultados El promedio de puntuación final de la escala AOFAS fue de 90 puntos y la inestabilidad se revirtió en el 96% de los casos, para ambos grupo de pacientes. El dolor fue aliviado eficientemente por ambas técnicas. No se observaron diferencias estadísticamente significativas entre los grupos del estudio. Discusión La reparación artroscópica de la inestabilidad crónica lateral del tobillo fue tan efectiva para restablecer la función, estabilidad y eliminar el dolor del tobillo como la técnica abierta y puede tener una menor posibilidad de complicaciones relacionadas con las heridas.

Background Chronic lateral ankle instability is a common condition in people with inversion sprains. Initial treatment is conservative, and if that does not work a surgical approach is recommended, such as that described by Broström and later modified by Gould, and is the most used and effective. With the advent of arthroscopic surgery, one of the authors (JBGG) has recently developed a minimally invasive technique that has been used in the Surgical Foot and Ankle Unit of Imbanaco Medical Centre for 8 years. Therefore, this work aims to determine functional outcomes of patients treated with the arthroscopic technique compared with the open technique of Broström-Gould. Methods A total of 111 patients were evaluated, including 50 with the open method, and 61 with arthroscopic surgery technique for chronic lateral ankle instability between January 2004 and December 2011. The American orthopaedic foot and ankle score (AOFAS) scale for ankle and hindfoot was used for measuring pain, function, and alignment, and a visual analogue scale (VAS) was used to assess the pain. Results The final AOFAS score was 90 points, and instability was reversed in 96% of cases, for both groups of patients. The pain was relieved efficiently by both techniques. There were no statistically significant differences between the study groups. Discussion Arthroscopic repair of chronic lateral ankle instability is an effective tool to restore the function and stability, as well as eliminate ankle pain, and is comparable in effectiveness with the conventional technique. Additionally, there is a lower chance of complications related to wounds.

Analysis of Results of Arthroscopic Repair of Triangular Fibrocartilage Complex (TFCC) Injury.

Background: Triangular fibrocartilage complex (TFCC) tears are a major source of ulnar-sided wrist pain and may result in patient disability, ranging from activities of daily living to high-level athletics. The purpose of this study is to evaluate the long-term clinical outcomes in patients affected by TFCC lesion and in association with or without distal radio ulnar joint (DRUJ) instability after arthroscopic repair. Methods: Younger patients (50 years of age or younger), presented with mechanical symptoms at least 6 weeks of failed conservative treatment, a positive, fovea! tenderness test, were included in the study. Patients were excluded if they had ulnar impaction syndrome, arthritis of wrist joint or other wrist pathology on arthroscopic examination. Final results were evaluated after 1 year. Results: Forty-nine wrists in 48 patients had arthroscopy for a possibly repairable peripheral TFCC tear during the study period. Thirty four wrists in 34 patients remained after exclusions. The Mayo score from pre-operative value 46.9±10.4 was increased to 91.7±5.0 postoperatively. At final follow-up, 2 patients had fovea! tenderness, and no patients had a piano-key sign or caput ulna. Conclusion: Arthroscopic repair for traumatic TFCC fovea! tear can restore stability to the DRUJ and provide satisfactory subjective and objective results without serious complications after more than 12 months' follow-up.

Arthroscopic Treatment of Isolated Teres Minor Tendon Tear: A Case Report

Arthroscopic repair of an isolated teres minor tendon tear without associated shoulder joint pathology has not been reported in the literature. We report on a case of isolated teres minor tendon tear after trauma. The patient complained of severe shoulder pain and progressive limited range of motion 4 months after the injury. Magnetic resonance imaging showed a full-thickness tear of the teres minor tendon at its musculotendinous junction and arthroscopic repair was performed. At 2 years follow-up, satisfactory clinical and radiological outcomes were observed with return to pre-injury level. Here, the authors report this case and provide a review of literature.

Arthroscopic Medial Meniscus Posterior Root Repair: Techniques and Current Issues / 대한정형외과학회잡지

Posterior root tears of the medial meniscus are radial tears, usually found in patients older than 50 years with degenerative articular cartilage. Partial menisectomy has been the conventional treatment for this condition. However, growing dissatisfaction with partial menisectomy for medial meniscus root tears has led to an increasing interest in meniscal repair. One method for medial meniscus root repairs involves suturing around the region of the tear where the sutures are pulled-out and fixed around the tibia. In another approach, a suture anchor was used for fixation of the medial meniscus root tear. Both methods improved functional outcome scores at least during a short-term follow-up period. However, complete healing of the repaired root seemed to be less predictable. Strict patient selection, good surgical skills and proper postoperative rehabilitation are the key factors for successful repairs of medial meniscus root tears.

Gender Affects Early Postoperative Outcomes of Rotator Cuff Repair

BACKGROUND: The literature does not provide consistent information on the impact of patients' gender on recovery after rotator cuff repair. The purpose of this study was to determine whether gender affects pain and functional recovery in the early postoperative period after rotator cuff repair. METHODS: Eighty patients (40 men and 40 women) were prospectively enrolled. Pain intensity and functional recovery were evaluated, using visual analog scale (VAS) pain score and range of motion on each of the first 5 postoperative days, at 2 and 6 weeks and at 3, 6, and 12 months after surgery. Perioperative medication-related adverse effects and postoperative complications were also assessed. RESULTS: The mean VAS pain score was significantly higher for women than men at 2 weeks after surgery (p = 0.035). For all other periods, there was no significant difference between men and women in VAS pain scores, although women had higher scores than men. Mean forward flexion in women was significantly lower than men at 6 weeks after surgery (p = 0.033) and the mean degree of external rotation in women was significantly lower than men at 6 weeks (p = 0.007) and at 3 months (p = 0.017) after surgery. There was no significant difference in medication-related adverse effects or postoperative complications. CONCLUSIONS: Women had more pain and slower recovery of shoulder motion than men during the first 3 months after rotator cuff repair. These findings can serve as guidelines for pain management and rehabilitation after surgery and can help explain postoperative recovery patterns to patients with scheduled rotator cuff repair.

Arthroscopic Treatment of Isolated Teres Minor Tendon Tear: A Case Report

Arthroscopic repair of an isolated teres minor tendon tear without associated shoulder joint pathology has not been reported in the literature. We report on a case of isolated teres minor tendon tear after trauma. The patient complained of severe shoulder pain and progressive limited range of motion 4 months after the injury. Magnetic resonance imaging showed a full-thickness tear of the teres minor tendon at its musculotendinous junction and arthroscopic repair was performed. At 2 years follow-up, satisfactory clinical and radiological outcomes were observed with return to pre-injury level. Here, the authors report this case and provide a review of literature.

Effect of a Sleep Aid in Analgesia after Arthroscopic Rotator Cuff Repair

PURPOSE: The aim of this study was to evaluate the effects and safety of a sleep aid for postoperative analgesia in patients undergoing arthroscopic rotator cuff repair. MATERIALS AND METHODS: Seventy-eight patients were prospectively assigned to either the zolpidem group (multimodal analgesia+zolpidem; 39 patients) or the control group (multimodal analgesia; 39 patients). Self-rated pain levels were assessed twice a day using a visual analog scale (VAS). The need for additional rescue analgesic, duration of functional recovery, and adverse effects were assessed for the first 5 days after surgery. RESULTS: The mean number of times that additional rescue analgesic was required during 5 days after surgery was 2.1+/-2.0 in the zolpidem group and 3.3+/-2.8 in the control group, a significant difference. There were no significant differences between the two groups in mean VAS pain scores during the first 5 days after surgery, although the zolpidem group had lower VAS pain scores than the control group. Additionally, there were no significant differences in duration of functional recovery and adverse effects between the two groups. CONCLUSION: The use of zolpidem for analgesia after arthroscopic rotator cuff repair provided a significant reduction in the need for rescue analgesic without increasing adverse effects. Nevertheless, mean VAS pain scores during the first 5 days after surgery did not differ between the zolpidem group and the control group.

INTRODUCTION: partial-thickness rotator cuff tears (supraspinatus tendon, infraspinatus) are considered twice as frequent as full thickness tears. Studies using arthroscopy as a method of choice for diagnosis and they turn it in the golden rule. Many surgeons consider fully maintain the healthy part of the tendon fibers and repair the rupture area; which is possible to comply with arthroscopic repair techniques. OBJECTIVE: evaluate the results of the application of arthroscopic technique for the diagnosis and repair of partial-thickness rotator cuff ruptures, preserving the healthy part of the tendon. METHODS: partial rotator cuff tears were repaired with arthroscopic suture anchor technique without completing thesupraspinatus and infraspinatus tendon rupture from January 2008 to May 2009. The study included 47shoulders, 34 partial tears of the joint surface, seven partial teras of bursal surface and 6 intratendinous partial tears. An average follow-up of 14.5 months (range 12-17 months) was conducted. Distribution by sex 34 male (72.3 %) and 13 female (27.7 %) and an average age of 47.5 years was performed. The dominant limb was affected in 38 patients (80.9 %). RESULTS: excellent results were obtained in 95.8% of patients and good results in 91.5 %. Results were assessed as excellent, good, regular according to the Constant-Murley scale results. CONCLUSIONS: arthroscopic repair using suture anchor technique without completing rupture offers advantages. Anatomy is conserved, while preserving the healthy part of the tendon and preventing progression to full thickness defects.

INTRODUCTION: les ruptures partielles de la coiffe de rotateurs (tendons du sus-épineux, du sous-épineux) sont considérées deux fois plus fréquentes que les ruptures complètes. Dans les études, l'arthroscopie est utilisée comme méthode de choix pour le diagnostic des ruptures de la coiffe des rotateurs, et dévient alors un gold standard. Plusieurs chirurgiens tendent à laisser intacte la partie saine des fibres tendineuses et à réparer seulement la zone de la rupture, ce qui est tout à fait possible grâce aux techniques de réparation sous arthroscopie. OBJECTIF: le but de cette étude est d'évaluer les résultats de la mise en application d'une technique de diagnostic et de réparation sous arthroscopie dans le traitement des ruptures partielles de la coiffe des rotateurs. MÉTHODES: depuis janvier 2008 jusqu'à mai 2009, on a éprouvé une technique de suture et d'ancrage sous arthroscopie pour la réparation des ruptures partielles de la coiffe des rotateurs. Cette étude a compris 47 épaules (34 ruptures partielles des capsules articulaires, 7 déchirures partielles de la bourse glénoïdale, et 6 ruptures partielles des tendons). On a réalisé un suivi de 14.5 mois en moyenne (12 à 17 mois), avec une distribution par sexes de 34 hommes (72.3 %) et 13 femmes (27.7 %), et une moyenne de 47.5 ans. Le membre supérieur dominant a été affecté chez 38 patients (80.9 %). RÉSULTATS: on a obtenu des résultats excellents et bons chez 91.5% des patients, et les résultats ont été évalués d'excellents, de bons et de moyens chez 95.8% des patients selon l'échelle de Constant-Murley. CONCLUSIONS: cette technique de suture et d'ancrage sous arthroscopie, sans compléter la rupture, montre des bénéfices; on protège l'anatomie en préservant la partie saine du tendon et en évitant l'évolution complète des anomalies au niveau de la coiffe.

Objetivo: Evaluar la evolución posoperatoria de una serie de pacientes mayores de 80 años sometidos a cirugía artroscópica para reparar el manguito rotador. Materiales y Métodos: Entre junio de 2004 y marzo de 2007, se evaluó a 20 pacientes de 80 años o más, a los que se les realizó una reparación artroscópica del manguito rotador. Todos habían recibido tratamiento conservador que no fue eficaz. En el seguimiento, se emplearon los puntajes de UCLA, Constant y Quick-DASH, y la escala analógica visual para el dolor, la función y la calidad de vida. Resultados: El seguimiento promedio fue de 28 meses (rango 24-48). El puntaje de UCLA fue de 10,4 preoperatorio y 28,6 posoperatorio (p < 0,05). El puntaje de Constant mejoró de 31,5 antes de la cirugía a 69,3 después de ella (p < 0,05). El puntaje de Quick-DASH mostró una mejoría de 33 a 16 puntos en el posoperatorio (p < 0,05). La escala analógica visual para el dolor preoperatorio arrojó 8 puntos y, en el posoperatorio, se obtuvo un promedio de 2,2 puntos (p < 0,05). No hubo complicaciones. Conclusiones: En esta serie de reparación del manguito rotador en personas mayores de 80 años, se obtuvieron mejoras significativas en todos los pacientes.

Background: The purpose of the study was to evaluate the functional postoperative outcome in patients aged 80 years or over undergoing arthroscopic rotator cuff repair. Methods: From June 2004 to March 2007, 20 patients aged 80 years or over underwent arthroscopic rotator cuff repair. All patients included had a history of unsatisfactory conservative treatment. Patients were evaluated in the preoperative and postoperative period using the UCLA score, Constant score, Quick-DASH score and visual analogue scale for pain, function, and quality of life. Results: The mean follow-up period was 28 months (range 24-48 months). The mean UCLA score improved from 10.4 points preoperatively to 28.6 postoperatively (p < 0.05). The Constant score improve 31.5 points preoperatively to 69.3 postoperatively (p < 0.05). The mean Quick-DASH score improved from 33 points preoperatively to 16 postoperatively (p < 0.05). The visual analogue scale for pain improved from 8 (range 5-9 points) to 2.2 (p < 0.05). There were not postoperative complications. Conclusions: In this series arthroscopic rotator cuff repair in patients aged 80 years or over demonstrates significant improvement in clinical outcomes and pain relief.

Does the Frequency of Passive Motion Exercises during the Early Period after Arthroscopic Rotator Cuff Repair Affect the Range of Motion at 3 Months Postoperatively? / The Japanese Journal of Rehabilitation Medicine

Objective : To investigate whether the frequency of passive motion exercises during the early period after arthroscopic rotator cuff repair affects the range of motion at three months postoperatively. Methods : We retrospectively evaluated 64 patients with rotator cuff tears who underwent arthroscopic repair. Range of motion (ROM) in forward flexion, abduction, external rotation, and internal rotation were assessed preoperatively and at three months postoperatively. Patients were supervised to wear an axillar pillow for six weeks and to commence passive ROM exercise at seven days postoperatively. Passive ROM exercises for 9 hours per week or more were performed in 41 patients (group A), and 3 hours or less of exercises were performed in 23 patients (group B). Results : There were no statistical differences between the two groups in age or gender proportion. The mean differences from preoperative ROM to postoperative ROM were 4° and 17° (group A and B, respectively) in flexion, 5° and 18° in abduction, -14° and -12° in external rotation, and -3 and -2 spinous processes in internal rotation, and there were no differences in all directions between the two groups. Even when subjects were limited to the patients without shoulder contractures preoperatively, there was no difference between the two groups. Conclusion : Early passive motion exercise for long hours after arthroscopic rotator cuff repair did not give a positive effect on early improvement in ROM. Scar formation and adhesion at the subacromial space may influence this outcome.

Choice of Initial Operation and Functional Outcome in Rotator Cuff Repair on Both Shoulder / 대한정형외과학회잡지

PURPOSE: We evaluated the influencing factors in selection of initial operation and outcomes after operative treatment of symptomatic rotator cuff tear including both sides. MATERIALS AND METHODS: From December 2000 to March 2011, 60 shoulders of 30 patients underwent arthroscopic rotator cuff repair by a single experienced shoulder surgeon in our clinic. We retrospectively compared outcome by operation order according to hand dominance, tear size and by operation timing, operation method, and tear size. Symptom period was 10 months until the first operation and 19 months until the second operation. Interval between first and second operation was nine months. RESULTS: In comparison by operation order according to hand dominance and tear size, the functional scores did not differ significantly between the initial repair and delayed repair group (p>0.05). In comparison in a total of 60 cases, the functional outcome according to the operation timing and method of operation was not significantly different (p>0.05). The smaller sized tear group showed significantly better functional outcome, compared to the larger sized tear group (p<0.05). CONCLUSION: In cases of both-side symptomatic rotator cuff tear, most operations were performed on the more symptomatic side and the dominant arm first. The functional outcome showed improvement, regardless of operation order according to hand dominance and tear size, and regardless of operation timing and operation method as well. Tear size was the only significant factor influencing functional outcome.

The Short Term Results of All-inside Arthroscopic Repair of the Triangular Fibrocartilage Complex Type 1B Tear by Knotless Suture Anchor

PURPOSE: We studied the short term results of the arthroscopic repair of 1B type triangular fibrocartilage complex (TFCC) tear using a knotless suture anchor. METHODS: We evaluated 23 patients who underwent all-inside arthroscopic TFCC repair using a knotless suture anchor. The average follow-up duration was 6.6 months (range, 3-10 months). Mean duration of symptom was 10.9 months (range, 1 week-7 years). The arthroscopic finding documented 15 type 1B, 2 1B with 1D, and 6 1B with 2C lesions. All showed the positive hook test. The concomitant pathologies were 16 scapholunate injuries and 10 lunotriquetral injuries. TFCC tears were repaired by the knotless suture anchor. The Wafer procedure was done for 2C lesions. RESULTS: According to Mayo modified wrist score, the result was excellent in 4, good in 14 and fair in 5. Nineteen patients (82.6%) could return to his job or hobby. CONCLUSION: The all-inside arthroscopic repair using knotless suture anchor for TFCC 1B tear can provide good results. The appropriate management should be done for the concomitant pathologies for the better results.

Introduction: the rupture of rotator cuff (tendons of the subscapularis, supraspinatus, infraspinatus and teres minor muscles) is a disease affecting the shoulder with a high incidence. It is more frequent present in persons practicing repetitive exercises and there is a background of trauma. Arthroscopic diagnosis with its advantages is definite and exact and the appropriate interpretation of it guarantees the success of repair. Objective: to assess the results of the arthroscopic repairs with the method of suture and anchorage in the total ruptures of rotator cuff applied in the Orthopedics service from October, 2007 to April, 2009. Methods: authors analyzed the results from 42 patients with total ruptures of rotator cuff, assessed using the Constant-Muley scale. A mean follow-up of 15.5 months was carried out with predominance of male sex (69 percent) and an average age of 56 years at surgery. Results: in the patients included surgery was carried out in the dominant limb in the 66.6 percente. The first general assessment of results at 6 postoperative months showed an 83.3 percent of excellent, goods and fair results. With time the results improved, at 12 months it was obtained the 97.6 percent of excellent, good and fair results in the series. Conclusions: the results of arthroscopic repairs of present series of cases are comparable with reports available in literature

Arthroscopic Percutaneous Repair of Anterosuperior Rotator Cuff Tear Including Biceps Long Head: A 2-Year Follow-up

BACKGROUND: To report the results of an arthroscopic percutaneous repair technique for partial-thickness tears of the anterosuperior cuff combined with a biceps lesion. METHODS: The inclusion criteria were evidence of the upper subscapularis tendon tear and an articular side partial-thickness tear of the supraspinatus tendon, degeneration of the biceps long head or degenerative superior labrum anterior-posterior, above lesions treated by arthroscopic percutaneous repair, and follow-up duration > 24 months after the operation. American Shoulder and Elbow Surgeons (ASES) score, constant score, the pain level on a visual analogue scale, ranges of motion and strength were assessed. RESULTS: The mean (+/- standard deviation) age of the 20 enrolled patients was 56.0 +/- 7.7 years. The forward flexion strength increased from 26.3 +/- 6.7 Nm preoperatively to 38.9 +/- 5.1 Nm at final follow-up. External and internal rotation strength was also significantly increased (14.2 +/- 1.7 to 19.1 +/- 3.03 Nm, 12.3 +/- 3.2 to 18.1 +/- 2.8 Nm, respectively). Significant improvement was observed in ASES and constant scores at 3 months, 1 year and the time of final follow-up when compared with preoperative scores (p < 0.001). The mean subjective shoulder value was 86% (range, 78% to 97%). CONCLUSIONS: The implementation of complete rotator cuff repair with concomitant tenodesis of the biceps long head using arthroscopic percutaneous repair achieved full recovery of normal rotator cuff function, maximum therapeutic efficacy, and patient satisfaction.

Modified Mason-Allen Suture Bridge Technique: A New Suture Bridge Technique with Improved Tissue Holding by the Modified Mason-Allen Stitch

We present a new method of suture bridge technique for medial row fixation using a modified Mason-Allen stitch instead of a horizontal mattress. Medial row configuration of the technique is composed of the simple stitch limb and the modified Mason-Allen stitch limb. The limbs are passed through the tendon by a shuttle relay. The simple stitch limb passes the cuff once and the modified Mason-Allen stitch limb passes three times which creates a rip stop that prevents tendon pull-out. In addition, the Mason-Allen suture bridge configuration is basically a knotless technique which has an advantage of reducing a possibility of strangulation of the rotator cuff tendon, impingement or irritation that may be caused by knot.

One Anchor Double Fixation (OADF) Technique for Arthroscopic Bony Bankart Repair

PURPOSE: The aim of this study was to evaluate the usefulness of arthroscopic Bony Bankart repair using a One Anchor Double Fixation Technique. MATERIALS AND METHODS: Seventeen patients with a Bony Bankart lesion were treated using the One Anchor Double Fixation Technique (OADF Technique). There were 13 males and 4 females. The average age was 24 years (range 17-42). The average follow-up period was 22.3 months. One 3.0 mm suture anchor with doubly loaded sutures was inserted into the glenoid rim. One suture strand was passed the around the small bony fragment and tied first. Another suture strand was passed through the capsule and tied over the bony fragment. The result was measured using Rowe's evaluation index & KSS score. The glenoid defect & bony fragment were measured by 3D-CT scan. RESULTS: Rowe's evaluation index on the final follow-up showed an overall improvement from an average of 54 (range, 23-71) to 83.4 (range 71-90). Of the 17 cases, 13 were excellent, 3 were good, and 1 was fair. KSS scores showed improvement from an average of 71 (range 49-82) to 92.5 (range 82-94). There were no cases where pain continued to the final follow-up, and no cases being re-dislocated during the follow-up period. For six cases, we confirmed the bony healing of the bony Bankart lesion by CT. CONCLUSION: Bony Bankart lesion repair using this new method achieves excellent clinical results with low recurrence rates and is considered another choice for bony Bankart lesions.

Arthroscopic Repair of Combined Rotator Cuff Tears Involving the Subscapularis Tendon / 대한정형외과학회잡지

PURPOSE: Subscapularis tendon tears associated with supraspinatus tendon tears are often found during rotator cuff repair. However, there have been only a few reports about both subscapularis and rotator cuff repair. The authors conducted arthroscopic repair for cuff tear associated with subscapularis tendon tear and assessed its outcomes. MATERIALS AND METHODS: We evaluated 320 cases of arthroscopic repair following rotator cuff tear between June 2006 and January 2009 at Gil Medical Center. Out of 66 cases (21%) associated with subscapularis tear, forty cases of bone to tendon repair using suture anchor were selected except for 26 cases of tendon to tendon repair. Clinical outcomes of 25 cases followed up for over a year were finally assessed. Clinical outcomes were evaluated using the following measures: range of shoulder motion, muscle strength, belly press test, Visual Analogue Scale (VAS) on pain, and University of California Los Angeles (UCLA) score. RESULTS: The average VAS pain scale improved from 5.3 preoperatively to 1.4 postoperatively. Internal rotation strength increased from its preoperative level, 4.1 to 4.2 in postoperative 6 months and to 4.6 at last follow-up. Range of internal rotation increased from the second lumbar level at postoperative 6 months to the 11th thoracic level at last follow-up. UCLA score had significantly improved from 17.4 to 30.8 (p<0.05). CONCLUSION: It is recommended that concurrent repair of the subscapularis tendon during rotator cuff repair for a satisfactory treatment result.

Correlación clínico-ecográfica en pacientes operados de reparación artroscópica del manguito rotator / Clinical and echographic correlationship between patients with rotator cuff tear arthroscopic repair

Rotator cuff (RC) is crucial in shoulder’s movement. Lesions due to degenerative changes because of aging and activity are frequent. Surgery is an adequate approach when conservative measures have failed. The aim of this study is to evaluate the clinical and echographic evolution of patients with RC surgical repair. Methods: patients with arthroscopic RC repair underwent pre and postsurgical clinical–echographic evaluation. Results: From 24 evaluated shoulders, 8 were found to have RC tear and 24 were found to not have tear. Clinical evaluation improve substantially in both groups, with no statistical differences among them. Conclusion: There is a significant amount of patients without RC tear after surgical repair. Although there are patients with RC tear on the echographic evaluation, therte are no clinical differences compared with patients with no RC tear. Older has higher risk of retear.

El manguito rotador (MR), es fundamental para el movimiento del hombro. Su lesión es frecuente debido a los cambios degenerativos que ocurren con la edad y la actividad. La cirugía es la alternativa cuando fracasan los tratamientos conservadores. Se plantea un estudio que permita evaluar la evolución clínica y ecográfica de pacientes a los que se le reparó el MR. Metodología: A pacientes operados mediante reparación artroscópica del MR se les realizó ecografías de control y evaluación clínica del dolor pre y postquirúrgico. Resultados: De 24 hombros evaluados se encontró 16 sin rotura y 8 con rotura. La evaluación clínica mejoró sustancialmente en ambos grupos, no encontrándose diferencias estadísticamente significativas entre ellos. Conclusiones: Existe un porcentaje importante de pacientes con MR sin lesión completa posterior a reparación. A pesar de haber pacientes con rotura de MR en la evaluación ecográfica, no hay diferencias clínicas con respecto a los sin rotura. A mayor edad existe una mayor posibilidad de re-rotura.
