Bankart Repair Using Modern Arthroscopic Technique

Biceps Rerouting Regardless of a Biceps-Labral Lesion During Rotator Cuff Repair Results in Lower Retear Rates and Comparable Clinical Outcomes to Subpectoral Biceps Tenodesis

PURPOSE

To evaluate the radiographic and clinical outcomes when rerouting a pathologic biceps during arthroscopic rotator cuff repair by comparing it with concomitant subpectoral biceps tenodesis (SPBT).

METHODS

This retrospective, historical cohort study was conducted with patients who underwent an arthroscopic repair of a full-thickness rotator cuff tear, with intraoperative confirmation of biceps pathology including partial tears, subluxation, pulley lesions, or type II SLAP lesions. Until May 2018, such patients were treated with concomitant subpectoral tenodesis (group SPBT). Afterward, biceps rerouting (BR) was done regardless of biceps pathology (group BR) without biceps or SLAP repair. Radiographic parameters, including fatty degeneration, acromiohumeral distance, Sugaya classification, and retears, were evaluated using preoperative and 1-year postoperative magnetic resonance imaging results. Clinical evaluation with a minimum 2-year follow-up included pain visual analog scale, American Shoulder and Elbow Surgeons, Simple Shoulder Test, and Constant-Murley scores. Whether individual patients exceeded these scores' minimal clinically important difference also was determined.

RESULTS

A total of 64 patients (group SPBT = 32; group BR = 32) were included in the final analysis. The duration of clinical follow-up was 36.2 ± 9.3 months in group SPBT and 29.4 ± 6.9 months in the BR group (P = .002). Compared with group SPBT, group BR demonstrated a significantly lower retear rate (SPBT vs BR: 34.4% vs 12.5%, P = .039). In the BR group, 8 of 32 (25%) patients demonstrated a postoperative LHBT tear. The 4 cuff retears in group BR only took place within these patients. Other postoperative radiographic and clinical outcomes were comparable between the groups. Within each group, significant postoperative improvements were demonstrated (P < .05 for all clinical scores).

CONCLUSIONS

Even in the presence of a pathologic LHBT and/or a type II SLAP lesion, augmenting the rotator cuff repair with BR significantly reduced retear rates while achieving clinical scores comparable with SPBT in a minimum 2-year follow-up.

Single Working Portal Technique with 70-Degree Arthroscope for Arthroscopic Bankart Repair

The Bankart lesion is a common injury to the labrum in the shoulder joint, usually resulting from anterior shoulder dislocation. Arthroscopic Bankart repair is a surgical technique used to treat recurrent dislocations by reattaching the labrum to the glenoid rim using suture anchors. Typically, 3 portals are created: 1 for visualization and 2 for instrumentation. However, this Technical Note proposes a single working portal approach using a 70° arthroscope from the posterior portal. This technique enhances visualization and prevents portal jamming, particularly in cases with a small rotator interval.

Time of Return to Work (RTW) May Not Correlate with Patient-Reported Outcomes Measurements (PROM) at Minimum One Year Post Arthroscopic Bankart Repair

It is widely recognized that work serves a dual role by not only ensuring financial independence but also functioning as a vital source of psychosocial well-being and contributing significantly to the attribution of meaning in life. The cost of work disability can be a multifactorial problem for both employers and workers; thus the inability to return to work (RTW) may have a destructive effect on mental health and confidence. Shoulder surgery is one of the conditions that inevitably impacts patients' ability to work. As current data focus on restoring range of motion, strength, and the patients' activity, to this day the data about RTW post shoulder surgery remain limited. The purpose of this study was to evaluate the return-to-work time of patients treated with an arthroscopic Bankart repair and to evaluate if patient-reported outcomes (PROM) correlate with the incapacity to work after an arthroscopic Bankart repair. We performed a retrospective review by conducting a questionnaire with patients more than 12 months after surgery and we identified 31 patients who met the criteria for the study and were able to contact 17 of them. In this paper we demonstrated that on average among groups working physically and at the office we may expect patients who underwent arthroscopic Bankart repair to return to work within 7 weeks from the surgery, with office workers tending to return significantly faster with an average of 2.5 weeks (p = 0.0239).

Results of arthroscopic treatment for anteroinferior shoulder instability using a single anterior working portal using birdbeak

BACKGROUND

The shoulder joint is the joint with the most dislocations in all joints. The arthroscopic surgery method is considered the gold standard because it creates less soft tissue damage, shorter hospitalization and surgery time, and less restriction of movement after surgery in shoulder instability. Anterior single portal technique has become popular recently. In this study, it was aimed to evaluate the results of the anterior single portal repair technique using "birdbeak". We try to evaluate if this technique is a reliable technique and has the same or more advantages of two portal arthroscopic surgery and make the surgery easier for surgeons.

METHODS

In the total of 40 patients who underwent arthroscopic surgery for traumatic recurrent anterior shoulder dislocation between January 2017 and February 2020, this study included 19 patients with the surgical technique of arthroscopic isolated anterior labrum tear repair using a birdbeak from the anterior single working portal. Clinical results were evaluated with the Simple Shoulder Test (SST), Rowe Score for Instability (RWS) and Oxford Shoulder Instability Score (OSIS) tests before and after surgery. The relationship between the time to surgery after the first dislocation and clinical outcomes was also examined in the study. Kolmogorov-Smirnov and Shapiro-Wilk tests were used to control the assumption of normality. In addition, Pearson correlation and Spearman correlation analyzes were used to test the relationship between the variables.

RESULTS

The mean follow-up period of the 19 patients included in this study was 33.1 months. The mean time to surgery after the first dislocation was 18.4 months. The mean preoperative number of dislocations was 5.3. The mean number of anchors used in the repair was 2.1. No recurrent dislocations were observed after surgery. A significant difference was observed between preoperative and postoperative SST, RWS and OSIS scores (respectively, p = 0.000 < 0.001, p = 0.000 < 0.001, p = 0.000 < 0.001). There was no statistically significant relationship between the time elapsed after the first dislocation and the postoperative SST, RWS, OSIS scores (respectively, p = 0.43 > 0.05, p = 0.39 > 0.05, p = 0.31 > 0.05).

CONCLUSION

It has been observed that the repair technique applied using the "birdbeak" from the anterior single working portal is a successful treatment, and further studies are required due to the limited literature.

The Longitude-Latitude-Loop Used for Complex Bankart Lesion Repair: An All-Arthroscopic Technique

The most frequent operation for anterior shoulder instability is the arthroscopic Bankart repair, which has a positive outcome and a low rate of complications. A variety of restoration procedures have been reported to reconstruct labral height and reproduce a dynamic concavity-compression reaction. The longitude-latitude loop is a knotless high-strength suture method that simultaneously tightens the joint capsule in the warp and weft direction and resists tearing. The suture method is safe and reproducible. This study aimed to present a longitude-latitude loop suture for joint capsule labral complex repair during Bankart arthroscopy surgery.

Outcomes After Arthroscopic Revision Bankart Repair: An Updated Systematic Review of Recent Literature

PURPOSE

To provide an update of recent literature with a specialized focus on clinical outcomes following arthroscopic revision Bankart repair (ARBR) by performing a systematic review of all available literature published between 2013 and 2020.

METHODS

A literature search reporting clinical outcomes after ARBR was performed. Criteria for inclusion consisted of original studies; Level of Evidence of I-IV; studies focusing on clinical outcomes after ARBR published between January 1, 2013, and January 4, 2021; studies reporting recurrent dislocation or instability rate after ARBR; reoperation/revision following ARBR, return to sport rates following ARBR; and patient-reported outcomes. The primary outcomes of interest were failure defined as recurrent instability or dislocation, return to sport rates, and patient-reported outcomes at follow-up.

RESULTS

A large proportion of patients undergoing arthroscopic revision Bankart repair were male, ranging between 67.7% and 93.8%. Failure rate and return to sports rate ranged between 6.1% and 46.8% and 25.9% and 88.3%, respectively, when patients with significant or greater than 20% glenoid bone loss was excluded. Patient-reported outcome scores, which included American Shoulder and Elbow Surgeons, Simple Shoulder Test, and visual analog scale, saw significant improvement over mean follow-up of ranging 21.64 to 60 months.

CONCLUSIONS

Both the failure rate and RTS rates after ARBR had a wide range, given the heterogeneity of the studies included, which varied in patient selection criteria pertaining to patients with greater than 20% glenoid bone. Although there have been advancements in arthroscopic techniques and a trend favoring arthroscopic stabilization procedures, there is a lack of consensus in recent literature for careful patient selection criteria that would minimize failure rates and maximize RTS rates after ARBR.

Arthroscopic anatomic glenoid reconstruction has a lower rate of recurrent instability compared to arthroscopic Bankart repair while otherwise maintaining a similar complication and safety profile

OBJECTIVES

The primary purpose of this study was to determine the frequency and type of complications, including subluxation, infection, hardware complication, graft/glenoid fracture, chondrolysis, neurovascular deficits and stiffness following an Arthroscopic Bankart Repair (ABR) or an Arthroscopic Anatomic Glenoid Reconstruction (AAGR) using a distal tibia allograft for recurrent anterior shoulder instability. Secondary purposes were to determine the frank dislocation rate and the associations of post-operative complications with demographic patient factors.

METHODS

Demographic and clinical data were reviewed using means ± standard deviations or frequencies in patients with recurrent anterior shoulder instability who underwent either an ABR or an AAGR. Post-operative patient records were analysed to identify any post-operative complications. The numerical variables of the two groups were compared using the independent t-test or Mann-Whitney U test. Categorical variables and complications were tested using the chi-square test, Fisher's exact test, or the two-sided Monte Carlo test with a significance level of 0.05.

RESULTS

We included 174 patients in this cohort, with 61.5% of patients receiving ABR and 38.5% receiving AAGR. Most of our patients were male (70.1%) with an average age of 23.41 ± 8.26 years in the ABR group and 29.37 ± 13.54 years in the AAGR group (p = 0.001). The two groups were similar with respect to their post-operative complication rates when excluding frank dislocation (ABR: 11%, AAGR: 12%). The AAGR group had statistically significantly higher rates of hardware removal compared to the ABR group (p = 0.004). The ABR group had 25 post-operative frank dislocations, with none reported in the AAGR cohort (p < 0.001). The total complication rate for each procedure was found to be 35% for ABR and 12% for AAGR.

CONCLUSION

AAGR has a comparable safety profile to the ABR when assessing post-operative complications such as subluxation, infection, graft/glenoid fracture, chondrolysis, neurovascular deficits and stiffness. AAGR is superior to ABR with respect to rates of recurrent instability and should be considered as a first-line treatment in certain patients with specific risk factors such as younger age, competitive contact sports participation, and higher number of instability events pre-operatively.

Patients without re-dislocation in the short term after arthroscopic knotless Bankart repair for anterior shoulder instability may show residual apprehension and recurrence in the long term after 5 years

HYPOTHESIS

The aim of this study was to report the long-term results, residual instability, and recurrence rate of arthroscopic Bankart repair surgery without a re-dislocation event in the first 5 years.

METHODS

We performed a retrospective analysis of Bankart repairs performed in a single center, by a single surgeon, with a minimum of 5 years' follow-up. Patients without a re-dislocation in the first 5 years of surgery were included. Patients who underwent open repair, those who underwent revision surgery, and those with critical glenoid bone loss were excluded. A total of 68 shoulders in 66 patients (51 male and 15 female patients) were included. Patients were analyzed in 2 domains: (1) failures defined as re-dislocation and (2) failures defined as apprehension and re-dislocation combined (residual instability). Clinical outcomes were assessed using shoulder range of motion, the American Shoulder and Elbow Surgeons score, and the Western Ontario Shoulder Instability Index (WOSI) score. Pain, residual apprehension, re-dislocations, and additional surgical procedures were recorded.

RESULTS

The mean age of patients was 31.16 (range, 16-60 years), and the mean follow-up duration was 8.42 ± 2.1 years. The median number of dislocations was 3 (range, 1-20), and the median time from first dislocation to surgery was 16 months (interquartile range, 3-100.5 months). Five patients reported re-dislocations (7.4%) with a mean period of 6.54 ± 2.5 years (range, 5-10.8 years). Seven patients without re-dislocations and 2 patients with re-dislocations reported residual apprehension. Mean shoulder elevation and mean external rotation were 161.3° ± 12.4° and 39.2° ± 11°, respectively. The mean visual analog scale, American Shoulder and Elbow Surgeons, and WOSI scores were 0.5 ± 1.4, 91 ± 11.9, and 88 ± 12.1, respectively. Age was similar in patients with stable shoulders and those with shoulders with re-dislocation or residual instability. The WOSI score was lower in patients with re-dislocation and residual instability (P = .030 and P = .049, respectively).

CONCLUSIONS

Arthroscopic Bankart repair is a successful surgical option for anterior shoulder instability. The 7.4% re-dislocation rate after 5 years indicates there may be a deterioration of capsulolabral repair in certain patients. The long-term failure pattern may be underestimated in short- to mid-term projections.

One shoulder (3.0%) had a postoperative subluxation event, and 1 shoulder (3.0%) required revision surgery for issues other than instability; 93.3% of players were able to RTS at the same level or higher for at least 1 season. Mean satisfaction was 8.9 ± 2.3. Mean VAS was 1.0 ± 1.7, and mean ASES and Rowe scores were 90.7 ± 18.5 and 89.7 ± 15.2, respectively.

CONCLUSION

Arthroscopic Bankart repair is an effective surgical intervention for traumatic anterior shoulder instability in NCAA and NFL football players. At a mean 6-year follow-up, surgery restored stability in 97% of cases and 93.3% returned to their preinjury level of sport.

Revision Arthroscopic Bankart Repair for Anterior Shoulder Instability After a Failed Arthroscopic Soft-Tissue Repair Yields Comparable Failure Rates to Primary Bankart Repair: A Systematic Review

BACKGROUND

The management of recurrent instability after arthroscopic Bankart repair remains challenging. Of the various treatment options, arthroscopic revision repairs are of increasing interest due to improved visualization of pathology and advancements in arthroscopic techniques and instrumentation.

PURPOSE

We sought to assess the indications, techniques, outcomes, and complications for patients undergoing revision arthroscopic Bankart repair after a failed index arthroscopic soft-tissue stabilization for anterior shoulder instability.

METHODS

We performed a systematic review of studies identified by a search of Medline, Embase, and PubMed. Our search range was from data inception to April 29, 2020. Outcomes include clinical outcomes and rates of complication and revision. The Methodological Index for Non-randomized Studies (MINORS) was used to assess study quality. Data are presented descriptively.

RESULTS

Twelve studies were identified, comprising 279 patients (281 shoulders) with a mean age of 26.1 ± 3.8 years and a mean follow-up of 55.7 ± 24.3 months. Patients had improvements in postoperative outcomes (eg, pain and function). The overall complication rate was 29.5%, the most common being recurrent instability (19.9%).

CONCLUSION

With significant improvements postoperatively and comparable recurrent instability rates, there exists a potential role in the use of revision arthroscopic Bankart repair where the glenoid bone loss is less than 20%. Clinicians should consider patient history and imaging findings to determine whether a more rigorous stabilization procedure is warranted. Large prospective cohorts with long-term follow-up and improved documentation are required to determine more accurate failure rates.

Comparison of the intraoperative efficacy of the powered rasp and conventional burr in arthroscopic resection of anterior ankle osteophytes

BACKGROUND

The efficacy of the powered rasp, a new reciprocating motion device for arthroscopic resection of osteophytes, has not been verified. The aim of this study was to compare the intraoperative efficacy of the powered rasp in arthroscopic resection of anterior ankle osteophytes to that of the conventional burr.

METHODS

A total of 49 consecutive patients who underwent arthroscopic resection of anterior ankle osteophytes (26 patients with the conventional burr and 23 patients with the powered rasp) were retrospectively reviewed. The preoperative volume of each osteophyte was measured using computerized tomography scan and three-dimensional software. The resection time was measured by review of the individual arthroscopy video, and the estimated resection rate was calculated as the volume of osteophytes/resection time.

RESULTS

The preoperative volume of osteophytes was not different between the two groups (847.8 ± 685.3 mm³ in the conventional burr and 913.3 ± 605.8 mm³ in the powered rasp, p = 0.726). The resection time was 442.4 ± 216.6 s (seconds) in the conventional burr and 386.4 ± 186.3 s in the powered rasp, and the estimated resection rate was 1.8 ± 1.0 mm³/s with the conventional burr and 2.4 ± 1.3 mm³/s with the powered rasp. These measurements were not significantly different between the two groups (p = 0.340 and 0.083, respectively).

CONCLUSION

The intraoperative efficacy of the powered rasp did not show superiority to that of the conventional burr in arthroscopic resection of anterior ankle osteophytes.

Does the immediate repair of Bankart lesion following first dislocation reduce the chances of recurrence after arthroscopic repair in soldiers?

PURPOSE

The study attempted to compare the effects of immediate and delayed arthroscopic Bankart repair on the shoulder dislocation recurrence.

METHODS

In total, 465 soldiers with first-time anterior shoulder dislocation were included in the study. Of the total, 285 soldiers underwent a quick arthroscopic Bankart repair procedure, whether 180 soldiers underwent a delayed repair procedure. The initial dislocation was traumatic in both groups and operated using the standard arthroscopic suture anchor repair technique. Patient's age, repair time since the first dislocation, number of dislocations before surgery, number of suture anchors used during the repair, duration of surgical procedure, duration from surgery to return to work, and recurrence of dislocation after surgery were recorded. Rowe score, Constant score, and American Shoulder and Elbow Surgeons score were used for clinical assessment.

RESULTS

The operating time and recurrence rate were higher in the group subjected to delayed repair procedure than in the group subjected to immediate repair procedure. Repair timing was found to be crucial for a successful outcome.

CONCLUSIONS

The findings suggest that Bankart repair must be performed immediately to minimize recurrence and other degenerative changes, which may require an additional surgical procedure for satisfactory repair. More studies are required to reach a definitive conclusion.

Comparison of efficacy between montgomery and Jobe technique and arthroscopic bankart repair in treating traumatic recurrent anterior shoulder dislocation

OBJECTIVE

To compare the clinical efficacy of Montgomery and Jobe technique versus arthroscopic Bankart repair in treating traumatic recurrent anterior shoulder dislocation (ASD).

METHODS

A total of 113 patients with traumatic recurrent ASD admitted to our hospital from June 2016 to January 2019 were selected as study subjects, and were divided into Group A and B in accordance with surgical options. The clinical data of the subjects were collected retrospectively. Group A was treated by the Montgomery and Jobe technique, while Group B was treated with arthroscopic Bankart repair. The arthroscopic manifestations were analyzed before and after arthroscopic Bankart repair. Scores of visual analogue scale (VAS) for shoulder joint and American Shoulder and Elbow Surgeons (ASES), Constant-Murley Score (CMS), Rowe Score, and complications were compared between the two groups before and after surgery.

RESULTS

Compared with Group A, Group B had a lower score of VAS for the shoulder joint, and higher scores of the range of motion (ROM), functional activities, myodynamia, pain, CMS, vital functions, ASES, and shoulder joint function, and a higher Rowe score after surgery (P < 0.05). The incidence rate (1.75%) of complications in Group B was lower than that (14.29%) in Group A (P < 0.05).

CONCLUSION

Arthroscopic Bankart repair is superior to the Montgomery and Jobe technique in treating traumatic recurrent ASD. Arthroscopic Bankart repair, exhibiting a high safety profile, is conducive to improving shoulder joint function and pain.

Outcomes of the arthroscopic Bankart procedure in Irish collision sport athletes

BACKGROUND

While there is an abundance of research examining the outcomes of the arthroscopic Bankart repair in collision athletes, very few studies have involved the unique Irish collision sport athlete population. The previously held belief that collision athletes need to be treated with open surgery, due to the high traumatic forces the shoulder is subjected to in these sports, may no longer be true in the context of modern arthroscopic techniques and implants.

AIMS

To report the outcomes of the arthroscopic Bankart procedure in the unique Irish collision athlete population.

METHOD

Retrospective review conducted in 2018. Data was obtained from collision sport athletes using customised questionnaires and validated, standardised outcome measure tools. Participants were selected using inclusion and exclusion criteria.

RESULTS

Fifty-four patients were included in the study. The average age at primary injury was 19.9 years (range 13-35 years). The rate of recurrent dislocation was 21% (12/57) with a mean follow up time of 24 months (range 7 to 48 months). The mean patient reported outcome measure (PROM) scores were as follows: ASES = 90.8, WOSI = 316.4, SSV = 79%. Six patients failed to return to their sport. Eighty-seven percent of the cohort returned to their sport, with a mean time to return of 7.25 months. Patients who experienced recurrent instability after arthroscopic Bankart had a younger age at primary dislocation (P = 0.0005) and lower ASES (P = 0.0056) and WOSI scores (0.00132) at latest follow-up, compared to those who remained stable postsurgery.

CONCLUSION

The arthroscopic Bankart procedure has a high rate of recurrence of dislocation in Irish collision sport athletes. The current international literature suggests that the arthroscopic Bankart has similar rates of recurrence to the open procedure in collision athletes; however, this may not hold true for Irish collision sport athletes. Further research is required to determine the optimum surgical procedure for anterior shoulder instability in this population, particularly those patients with subcritical bone loss.

Perceived vs. true glenoid anchor placement: a cadaveric comparison of the beach chair and lateral position

Purpose

To explore whether patient position influences a surgeon’s ability to accurately judge anchor position on the glenoid.

Materials and Methods

Two anchors were inserted into the glenoid of 8 shoulders. Arthroscopic videos were taken from 3 views (posterior beach chair [pBC], posterior lateral decubitus [pLD], and anterosuperolateral decubitus [asLD]). The shoulders were disarticulated to identify “true” anchor position. Seventeen shoulder surgeons reviewed the videos and indicated anchor positions using the “clock face” method. Accuracy was measured within tolerances, ranging from zero (exact), 0.5 (half-hour), 1.0, and 1.5 hours of “true” position. Intra- and inter-rater agreement was calculated. Post hoc analyses explored for bias dependent on surgical side.

Results

The overall accuracy was 34.0%. At tolerances of 0.5, 1.0, and 1.5 hours, accuracy increased to 82.4%, 95.4%, and 98.0%. With a 30° scope, identification of exact position was more accurate in pBC than pLD (odds ratio [OR] = 1.397; P = .029) but not asLD (OR =1.341; P = .197). At a tolerance of 0.5 hour, the 30° scope was more accurate in pBC than both pLD (OR = 1.444; P = .011) and asLD (OR = 1.728; P = .009). In left shoulders, anchors were perceived as more inferior than true position in asLD and pLD. In right shoulders, anchors were perceived as more superior than true position from pBC and pLD. Inter- and intrarater agreement were highest in pBC with a 30° scope (30° scope weighted kappa = 0.783 and 70° scope weighted kappa = 0.853, respectively).

Conclusion

Judgment of anchor position on video is most accurate in a pBC view. Inter- and intrarater reliability were also highest from a pBC view.

Arthroscopic Anatomic Glenoid Repair Using Distal Tibial Allograft and an Inferior-to-Superior Capsular Shift

Traumatic anterior dislocation of the shoulder accounts for the vast majority of shoulder dislocations. Recurrence following initial traumatic dislocation is common, and the risk is increased by the presence of both bony and soft-tissue damage. Arthroscopic procedures have been described to address each of these etiologies individually but have not provided a technique to address bony and soft tissue pathology concurrently. This paper describes an all-arthroscopic, anatomic glenoid repair using distal tibial allograft with an inferior-to-superior capsular shift, addressing significant glenoid bone loss and capsular laxity with a single operation.

Mid-term to long-term results of primary arthroscopic Bankart repair for traumatic anterior shoulder instability: a retrospective study

Background

The arthroscopic method offers a less invasive technique of Bankart repair for traumatic anterior shoulder instability. The aim of the study is to determine the mid−/long-term functional outcome, failure rates and predictors of failure after primary arthroscopic Bankart repair for traumatic anterior shoulder instability.

Methods

A total of 100 patients were primarily operated using arthroscopic Bankart repair after traumatic anterior shoulder instability. Medical records were retrospectively reviewed, and patients were assessed using postal questionnaire after a mean follow-up of 8.3 years [3–14]. Clinical assessment was performed using Constant score, Rowe score, and American Shoulder and Elbow Surgeons score.

Results

The overall recurrence rate was 22%. The Kaplan-Meier failure-free survival estimates.

were 80% at 5 years and 70% at 10 years. Nearly half (54.5%) of recurrences occurred at 2 years postoperative. Compared with normal shoulder, there were statistical differences in all 3 scores. Failure rate was significantly affected by age at the time of surgery with 86% of recurrence cases observed in patients aged 30 years or younger. Nevertheless, Younger age at the time of surgery (P = 0.007) as well age at the time of initial instability (P = 0.03) was found to correlate negatively with early recurrence within 2 years of surgery. Among those with recurrent instability, recurrence rate was found to be higher if there had been more than 5 instability episodes preoperatively (P = 0.01). Return to the preinjury sport and occupational level was possible in 41 and 78%, respectively.

Conclusion

Failure-free survival rates dropped dramatically over time. Alternative reconstruction techniques should be considered in those aged ≤30 years due to the high recurrence rate.

Prospective study on effectiveness and safety of arthroscopic Bankart using a single anterior portal for patients with anterior shoulder instability

OBJECTIVE

To evaluate the effectiveness and safety of the arthroscopic Bankart repair technique using a single anterior portal in patients with anterior shoulder instability.

PATIENTS AND METHODS

Prospective study of 82 patients who underwent arthroscopic Bankart repair using a single anterior portal. Comparison with a historical series of 69 patients treated with two anterior portals. The patients were evaluated by the Rowe scale, and DASH (Disability of the Arm, Shoulder and Hand) and OIS (Oxford Instability Shoulder) questionnaires, range of motion and visual analogue scales for pain and patient satisfaction.

RESULTS

After a mean follow-up of 36 months, there were no significant differences between groups regarding clinical or functional scores, quality of life or patient satisfaction. Surgical time was significantly shorter in the 1-portal group. In group 1-portal there were 2 patients with neurapraxias and 2 re-dislocations, while in group 2-portals were 1 and 2, respectively. The worst functional results were associated with the presence of a type III SLAP lesion.

CONCLUSIONS

Both techniques were satisfactory regarding functional outcomes and complications, except for type III SLAP lesions. Using only one anterior portal, the surgical time was shorter, and the costs were lower when dispensing with a second cannula and a suture passing instrument.

Anterior Shoulder Stabilization Using a Single Portal Technique With Suture Lasso

Open Bankart repair was the standard technique used in the past, but the request for less invasiveness, always pursued by every surgeon, pushed the development of the arthroscopic procedure. Nowadays the stabilization of the anteroinferior labrum is usually performed with an arthroscopic technique that uses the classic posterior portal and 2 anterior working portals. Because arthroscopy is progressing steadily under every aspect, there is now the chance to use only one working portal with the aid of a suture passer. One less portal not only means less invasiveness but also less postoperative pain and possible shorter operative time. This Technical Note is focalized in the description of a Bankart repair technique with a single working portal and the aid of a suture lasso.
