Unicortical versus bicortical plate fixation for midshaft clavicular fractures.

BACKGROUND: The aim of this study was to compare the functional and radiological outcomes of unicortical vs bicortical fixation in patients with midshaft clavicular fractures who were treated using pre-contoured locking plates. METHODS: We performed a prospective multicenter study of 45 individuals who underwent open reduction and internal fixation of midshaft clavicular fractures with precontoured locking plates between March 2017 and December 2019. Twenty-five patients were treated with bicortical screws and 20 patients with unicortical screws. Functional outcomes were assessed at 6 months and 12 months after surgery using the Constant score, the 11-item version of the Disabilities of Arm, Shoulder and Hand (Quick- DASH) score and the Single Assessment Numeric Evaluation (SANE) score. Pain was evaluated using a visual analog scale (VAS). The rate of return to work and sports was also recorded. Radiologic evaluation was obtained in the immediate postoperative day, monthly until fracture consolidation, at 6 months and 12 months. All intraoperative and postoperative complications were documented. RESULTS: At both 6 and 12 months, the follow-up rates were 100%, and the mean age was 28.5 years (range, 20 to 45 years). The mean postoperative Constant score, Quick DASH, and SANE score at 12 months were 93.5 (±6), 2.3 (±3), and 92% (±7), respectively. There were no significant differences in the functional scores between the groups neither at 6 months nor at 12 months. Of the 30 active workers, 97% were able to return to their previous working routine and from the 25 patients who practiced sports before the injury,92% returned to sports all at the same level. All the fractures healed in both groups. There were 6 complications (13%). CONCLUSION: In young, active patients with displaced midshaft clavicular fractures, both unicortical and bicortical locked plates achieved 100% bone consolidation, with excellent functional outcomes and a low rate of complications without significant differences between the groups. Therefore, locked plates with unicortical fixation could be a very good alternative for the management of young patients with midshaft clavicular fractures, potentially avoiding severe neurovascular complications. LEVEL OF EVIDENCE: Prospective comparative (Level II).

Substantial Variability in Platelet-Rich Plasma Composition Is Based on Patient Age and Baseline Platelet Count.

Purpose: To evaluate the effect of age, sex, body mass index (BMI), and baseline blood count on the final composition of platelet rich-plasma (PRP) and to evaluate the variability of PRP applied in the same patient at 2 different times. Methods: Potential subjects treated with PRP between January 2019 and December 2021 were identified in an institutional registry. Patient demographics and baseline blood count were prospectively recorded in a consecutive series of patients treated with PRP for a musculoskeletal condition in our Institution. The influence of sex, BMI, age, and baseline blood count on final platelet concentrations in PRP was evaluated. Finally, intrapersonal variability was evaluated. Results: A total of 403 PRP injections from 357 patients were analyzed from an institutional prospective registry of PRP between January 2019 and December 2021. A directly proportional variation in PRP platelet count of 3.8× was observed for each unit increase in baseline blood platelet count. For every decade increase, we observed an approximate decrease of 32,666 platelets. When the first dose of PRP platelet counts was compared with the second dose of PRP platelet counts between the same patients, significant differences were found. A mean of 890,018 platelets in the first PRP and a mean of 1,244,467 in the second PRP with a mean difference of 354,448 was found (P = .008). We did not find differences in the final concentration of platelets regarding sex, BMI, or PRP protocol. Conclusions: Overall the final composition of PRP (platelet count) was significantly influenced by patient's age and baseline platelet count. In contrast, BMI, sex and the rest of the components of the baseline blood count did not have a significant influence on final PRP. Furthermore, in patients who received 2 doses of PRP, the final concentration of platelets varied significantly between the 2 preparations. Level of Evidence: Level IV, prognostic case series.

A 2-Year Follow-up May Not be Enough to Accurately Evaluate Recurrences After Arthroscopic Bankart Repair: A Long-term Assessment of 272 Patients With a Mean Follow-up of 10.5 Years.

BACKGROUND: There is a great discrepancy between the rates of recurrent instability reported after arthroscopic Bankart repair in relation to the follow-up time. PURPOSE: To analyze the rate of recurrences after arthroscopic Bankart repair in the long term, emphasizing whether a minimum follow-up of 2 years is adequate to assess this outcome. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Between January 2008 and April 2013, a total of 356 athletes underwent arthroscopic Bankart repair for anterior glenohumeral instability at our institution. Return to sports, the Rowe score, the Subjective Shoulder Value (SSV), and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. We analyzed the proportion of recurrences before and after 4 years of follow-up. Additionally, we performed a Kaplan-Meier analysis to evaluate recurrence-free time in patients with a recurrence. RESULTS: The mean follow-up was 10.5 ± 1.6 years, and the mean age was 20.8 ± 3.9 years. In total, 90% of patients were able to return to sports; of these, 91% returned to their preinjury level of play. The Rowe, SSV, and ASOSS scores showed a statistical improvement after surgery (P < .01). The proportion of patients with a recurrence during the follow-up period was 25% (95% CI, 20%-31%; n = 70), and the mean time until a recurrence was 3.8 ± 2.6 years. Only 39% of the recurrences (95% CI, 30%-48%) occurred in the first 2 years after surgery, while 61% (95% CI, 50%-73%) occurred in the first 4 years after surgery. CONCLUSION: In our study, the effectiveness of Bankart repair to stabilize the shoulder decreased significantly over time. Indeed, less than half of the recurrences occurred after 2 years of follow-up. Therefore, we propose that the recommended minimum follow-up should be 4 years; otherwise, it is very likely that the actual rate of recurrences will be significantly underestimated.

The Short, 5-Item Shoulder Instability-Return to Sport After Injury Score Performs as Well as the Longer Version in Predicting Psychological Readiness to Return to Sport.

PURPOSE: To reduce the length of the Shoulder Instability-Return to Sport After Injury (SIRSI) scale and determine the predictive validity of the short version compared with the original form. METHODS: This study included patients who underwent an arthroscopic Bankart repair or open Latarjet procedure between 2017 and 2019. One group was used for the SIRSI scale-reduction process, and a second group was used to test the predictive validity of the proposed short SIRSI scale. The Cronbach α value was used to evaluate internal consistency. Validity was determined by calculating the Pearson correlation coefficient with the Western Ontario Shoulder Instability Index scale. Predictive validity was assessed using receiver operating characteristic (ROC) curve statistics. RESULTS: A total of 158 patients participated in the scale-reduction process, and 137 patients participated in the predictive-validation process. The SIRSI scale was successfully reduced to a 5-item scale constructed by 1 underlying factor accounting for 60% of the variance. The short version showed good internal consistency (Cronbach α = 0.82) and was highly correlated with the Western Ontario Shoulder Instability Index scale and the long version. The short SIRSI scores were significantly different between patients who returned to sports and those who did not. The SIRSI scale had excellent predictive ability for return-to-sport outcomes (area under ROC curve of 0.84 for short version [95% confidence interval, 0.7-0.9] and 0.83 for long version [95% confidence interval, 0.7-0.9]). CONCLUSIONS: A valid 5-item, short version of the SIRSI scale was successfully developed in our patient population. The short version was found to be as robust as the long scale for discriminating and predicting return-to-sport outcomes. LEVEL OF EVIDENCE: Level II, prospective cohort study.

Similar Clinical, Return to Sports, Recurrence, and Revision Outcomes Between Female and Male Athletes Following Arthroscopic Bankart Repair.

PURPOSE: To compare return to sports, functional outcomes, and recurrences rates between female and male athletes following arthroscopic Bankart repair (ABR). METHODS: A retrospective comparative study was performed between male and female athletes who underwent an ABR between January 2008 and December 2019. Sports practiced primarily by men in our practice (including rugby, soccer, boxing, and martial arts) were excluded. Functional outcomes included the Rowe score, visual analog scale (VAS) for pain, and shoulder-dependent sports ability measured with the Athletic Shoulder Outcome Scoring System (ASOSS). Return to sport, recurrence, and revisions were evaluated. Additionally, we assessed the period (months) between surgery and recurrence events. RESULTS: A total of 58 female and 106 male patients were available for analysis at a median follow-up of 60 (interquartile range [IQR], 36-84) months. Ninety-one percent of the patients (n = 150) returned to sports and 84% (n = 126) returned to their preinjury level at a median of 6 months (IQR, 5-8) postoperatively. There were no differences in the rate of return to sports between females and males (91 vs 92% respectively, P = .997). There were no differences between the groups regarding postoperative functional outcomes, with most patients achieving the minimal clinically significant difference (Rowe: 98% female and 99% male, P = .584; ASOSS: 100% female and 99% male, P = .646). The overall recurrence rate was 9.7% (n = 16), with a rate of 10.3% (n = 6) in female and 9.4% (n = 10) in male athletes (P = .851). Time to event analysis showed that the median time to recurrence was 48 months in both groups (P = .848). The overall revision rate was 3% (n = 4), without significant differences between groups (P = .556). CONCLUSIONS: When compared within similar sports, there does not appear to be sex-related differences in functional outcomes, recurrence, or return to play following ABR. LEVEL OF EVIDENCE: III, retrospective comparative study.

Classic Versus Congruent-Arc Latarjet Procedures.

Glenohumeral instability remains a frequent pathology, specifically in athletes and active patients. As such, several treatment options have been described. In the setting of significant glenoid bone loss (i.e., >20%), off-track Hill-Sachs lesions, and failed previous soft-tissue-based repairs, glenoid bone-augmentation techniques must be considered. These techniques restore stability by a triple blocking effect of the bony graft, the capsulolabral complex repair, and the dynamic sling effect of the conjoined tendon. The classic Latarjet procedure consists in performing a coracoid osteotomy along with the conjoined tendon attachment followed by transfer and fixation to the anterior glenoid, positioning the lateral surface of the coracoid to be flush with the articular side. Then, a modification of this technique defined as "congruent-arc Latarjet" (CAL) was described. This approach involves rotating the coracoid process 90° along its longitudinal axis using the inferior surface to recreate the native glenoid arc. Biomechanical studies have discussed advantages and disadvantages of these techniques. The CAL allows a greater glenoid surface area, which may be relevant in patients with increased glenoid bone loss. However, the bone contact area is reduced, which increases the technical difficulty of screw positioning with an increased risk of graft fragmentation. The classic Latarjet technique has a greater initial fixation strength between the graft and the glenoid and a greater potential for bone consolidation due to the broader contact bone area. Excellent clinical and sports outcomes with low recurrence rates have been observed in both techniques. Imaging findings have exhibited high bone block healing and no difference in graft placement, but CAL demonstrated a greater incidence of fibrous or nonunion rates and errors in screw fixation. Finally, while similar early complications have been reported, long-term outcomes are still needed in CAL for comparing osteoarthritis progression. These results emphasize that either technique can be considered to manage glenohumeral instability when appropriately indicated.

Effect of Playing Position on Return to Sport, Functional Outcomes, and Recurrence After Arthroscopic Bankart Repair in Soccer Players.

Background: Little attention has been paid to playing position as a risk factor for recurrence after arthroscopic Bankart repair (ABR) in soccer players. Purpose: To compare return to sport, functional outcomes, and recurrence after ABR between goalkeepers and field position players in soccer. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective comparative cohort study was performed in soccer players who underwent ABR between January 2017 and December 2019. The minimum clinical follow-up was 2 years. Functional outcomes included the Rowe score, visual analog scale (VAS) for pain, and shoulder-dependent sports ability measured with the Athletic Shoulder Outcome Scoring System (ASOSS). The difference between the post- and preoperative scores was calculated; rate and level of return to sport, recurrent instability, and revisions were also evaluated according to position played. Results: A total of 70 position players and 11 goalkeepers met the study criteria. Postoperative functional outcomes were significantly improved in both groups as compared with baseline (P < .001 for both), although the position players achieved significantly greater pre- to postoperative improvement (ΔVAS, -2 vs 0 points [P = .029]; ΔRowe, 45 vs 30 points [P = .046]; ΔASOSS, 45 vs 40 points [P = .028]). While all players returned to soccer, only 55% (n = 6) of goalkeepers returned to the same level versus 93% of field players (P = .003). The overall rate of recurrent instability was 8.6% but was significantly higher among goalkeepers (27.2% vs 5.7%; P = .049), and the odds of goalkeepers having a recurrence were significantly higher than field position players (odds ratio, 8.5 [95% CI, 1.2-57.2]; P = .027). Conclusion: Although the results of ABR were generally favorable in all soccer players, goalkeepers had significantly worse functional outcomes, a lower rate of return to the same level of sport, and a higher recurrence rate as compared with field position players.

Relationship of the SIRSI Score to Return to Sports After Surgical Stabilization of Glenohumeral Instability.

BACKGROUND: Literature is scarce regarding the influence of psychological readiness on return to sports after shoulder instability surgery. PURPOSE: To evaluate the predictive ability of the Shoulder Instability-Return to Sport after Injury (SIRSI) score in measuring the effect of psychological readiness on return to sports and to compare it between athletes who returned to sports and athletes who did not return to sports. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: A prospective analysis was performed of patients who underwent an arthroscopic Bankart repair or a Latarjet procedure between January 2019 and September 2020. Psychological readiness to return to play was evaluated using the SIRSI instrument. Preoperative and postoperative functional outcomes were measured by the Rowe, Athletic Shoulder Outcome Scoring System, and Western Ontario Shoulder Instability Index scores. The predictive validity of the SIRSI was assessed by the use of receiver operating characteristic (ROC) curve statistics. The Youden index was calculated and used to determine a SIRSI score cutoff point that best discriminated psychological readiness to return to sports. A logistic regression analysis was performed to evaluate the effect of psychological readiness on return to sports and return to preinjury sports level. RESULTS: A total of 104 patients were included in this study. Overall, 79% returned to sports. The SIRSI had excellent predictive ability for return-to-sport outcomes (return to sports: area under ROC curve, 0.87 [95% CI, 0.80-0.93]; return to preinjury sports level: area under ROC curve, 0.96; [95% CI, 0.8-0.9]). A cutoff level of ≥55 was used to determine whether an athlete was psychologically ready to return to sports and to return to preinjury sports level (Youden index, 0.7 and 0.9, respectively). Of those who returned to sports, 76.8% were psychologically ready to return to play, with a median SIRSI score of 65 (interquartile range, 57-80). In comparison, in the group that did not return to sports, only 4.5% achieved psychological readiness with a median SIRSI score of 38.5 (interquartile range, 35-41) (P < .001). Regression analysis for the effect of SIRSI score on return to sports was performed. For every 10-point increase in the SIRSI score, the odds of returning to sports increased by 2.9 times. Moreover, those who did not achieve their preinjury sports level showed poorer psychological readiness to return to play and SIRSI score results. CONCLUSION: The SIRSI was a useful tool for predicting whether patients were psychologically ready to return to sports after glenohumeral stabilization surgery. Patients who returned to sports and those who returned to their preinjury sports level were significantly more psychologically ready than those who did not return. Therefore, we believe that the SIRSI score should be considered along with other criteria that are used to decide whether the patient is ready to return to sports.

Return to sports, functional outcomes, and recurrences after arthroscopic Bankart repair in soccer players.

Background: There is a shortage of relevant reports about the results obtained after shoulder stabilization in soccer players. Therefore, this retrospective study aims to report return to sports, functional outcomes, and recurrences after arthroscopic Bankart repair in soccer players. Methods: A total of 156 soccer players were treated for anterior shoulder instability at a single institution between 2008 and 2017. The Rowe score and Athletic Shoulder Outcome Scoring System were used to assess functional outcomes. Return to sport and recurrence rates were also evaluated. Results: The Rowe and Athletic Shoulder Outcome Scoring System scores showed statistical improvement after surgery (P < .001). Overall, 148 soccer players (94.8%) returned to sports, and 122 (78.2%) returned to the same level. The mean time to return to sport was 4.8 months. The recurrence rate was 5.2%. Discussion: Soccer players who underwent an arthroscopic isolated Bankart repair for anterior glenohumeral instability have shown remarkable outcomes, with most of the patients returning to sports, and at the same level they had before surgery with a low rate of recurrence.

The playing position significantly influences return to sports and recurrences after an arthroscopic Bankart repair in competitive rugby players.

Background: The purpose of our study was to investigate the influence of the different rugby playing positions on return to sports, functional outcomes, and recurrences after an arthroscopic Bankart repair. Methods: A total of 88 rugby players were treated for anterior shoulder instability in our institution between 2010 and 2018. Functional outcomes, return to sports, recurrences, complications, and revisions rates were evaluated according to the playing position. Results: Overall, 73.8% of the patients returned to rugby and 60% returned at the same level as before the injury. The tight forwards and outside backs experienced a significant decrease in their competitive level after surgery, and showed the lowest functional outcomes. The tight forwards and outside backs showed a statistically significant increase in recurrence and revision rates, and an OR for recurrence of 12.8 and 9.6, respectively. Discussion: The playing position significantly influenced return to sports and recurrences after an arthroscopic Bankart repair in competitive rugby players. Specifically, the tight forwards and outside backs have returned to a lower level than they had before surgery, showed the lowest functional outcomes, and a significant increase in recurrences and revisions rates than the other groups.

The Latarjet procedure in competitive athletes younger than 20 years old with a significant glenoid bone loss.

Purpose: To analyze return to sports, functional outcomes, and complications following the Latarjet procedure in competitive athletes younger than 20 years old with a significant glenoid bone loss. Methods: Between 2010 and 2017, 60 competitive athletes younger than 20 years old with a significant glenoid bone loss were operated with the Latarjet procedure. Return to sports, range of motion, and the Rowe and the Athletic Shoulder Outcome Scoring System score were used to assess functional outcomes. Complications and bone consolidation were also evaluated. Results: The mean follow-up was 58 months and the mean age was 16.3 years. Overall, 93% were able to return to sports and 84% returned at the same level. The Rowe and Athletic Shoulder Outcome Scoring System scores showed statistical improvement after operation (P < .001). The total complication rate was 22% and the revision rate was 1.6%. The recurrence rate was 3.3%. The bone block healed in 93% of the cases. Conclusions: In competitive athletes younger than 20 years old with a significant glenoid bone loss, the Latarjet procedure resulted in excellent functional outcomes, with most of the patients returning to sports and at the same level they had before injury with a low rate of recurrences. However, this procedure is associated with a significant rate of complications and should preferably be performed by experienced surgeons.

Factors That Influence the Return to Sport After Arthroscopic Bankart Repair for Glenohumeral Instability.

Numerous studies have reported high rates of return to sports following arthroscopic Bankart repair (ABR) However, there is enormous controversy regarding the optimal management of these patients in the postoperative period. Controversy issues include rehabilitation, criteria for returning to sports, and the specific management of each athlete according to the sport they practice. Even though there are several rehabilitation protocols published in the literature, wide variability exists concerning the key elements of rehabilitation after an ABR. Regarding criteria for return to sports, there is a wide variation across the different published studies. The type of sports has been shown to affect an athlete's decision to return to sports. Nevertheless, most research is evaluated by classifications that cluster different sports into categories that may have other influences in return to sports when analyzed separately. Finally, in addition to physical readiness, the athlete's psychological state is crucial for returning to sports. However, the contribution of psychological readiness to an athlete's return to sports after shoulder instability surgery remains uncertain and unexplored.

Reasons Why Athletes Do Not Return to Sports After Arthroscopic Bankart Repair: A Comparative Study of 208 Athletes With Minimum 2-Year Follow-up.

BACKGROUND: There is a lack of information regarding the reasons why patients do not return to sports after an arthroscopic Bankart repair and whether there is a relationship between return to sports and functional outcomes. PURPOSE: To evaluate the reasons why competitive athletes who underwent arthroscopic Bankart repair did not return to sports and whether there was a relationship between returning to sports and postoperative outcome scores and complications. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Of 217 competitive athletes who underwent arthroscopic Bankart repair for isolated anterior glenohumeral instability between June 2014 and December 2017, a total of 208 athletes (96%) were evaluated at minimum 2-year follow-up. Return to sports, the level of sports achieved, and the time between surgery and return to competition were assessed, and patients who did not return to sports were asked to provide the reasons for cessation. The Rowe score and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. Recurrences, reoperations, and complications were also evaluated. RESULTS: The mean patient age was 24 years (range, 18-30 years), and the mean follow-up was 44 months (range, 24-90 months). Of the 208 athletes, 73% were able to return to sports (65% returned to their preinjury level), and 27% did not return to sports. Of those who did not return, the most frequent reasons were fear of reinjury (44%), lack of confidence in their shoulder (12%), and concern about a new rehabilitation process in case of recurrence (10%). The Rowe and ASOSS scores showed significant postoperative improvement in all patients (P < .001), with no significant differences between the 2 study groups at the final follow-up. There were 21 recurrences (10%) and 5 complications (2.4%), and 11 patients (5.3%) underwent revision surgery, with no significant differences in these rates between the groups. CONCLUSION: Of patients who did not return to sports, 74% left for a reason independent of shoulder function, with the most frequent causes being fear of reinjury and a concern about new rehabilitation process. Neither outcome scores nor complications varied significantly between patients who returned and those who did not return to sports.

Recurrence and Revision Rates With Arthroscopic Bankart Repair Compared With the Latarjet Procedure in Competitive Rugby Players With Glenohumeral Instability and a Glenoid Bone Loss <20.

BACKGROUND: There is a lack of evidence in the literature comparing outcomes between the arthroscopic Bankart repair and the Latarjet procedure in competitive rugby players with glenohumeral instability and a glenoid bone loss <20%. PURPOSE: To compare return to sport, functional outcomes, and complications between the arthroscopic Bankart repair and the Latarjet procedure in competitive rugby players with glenohumeral instability and a glenoid bone loss <20%. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Between June 2010 and February 2018, 130 competitive rugby players with anterior shoulder instability were operated on in our institution. The first 80 patients were operated on with the arthroscopic Bankart procedure and the other 50 with the open Latarjet procedure. Return to sport, range of motion (ROM), the Rowe score, and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. Recurrences, reoperations, and complications were also evaluated. RESULTS: In the total population, the mean follow-up was 40 months (range, 24-90 months) and the mean age was 24.2 years (range, 16-33 years). Ninety-two percent of patients were able to return to rugby, 88% at their preinjury level of play. Eighty-nine percent of patients in the Bankart group and 87% in the Latarjet group returned to compete at the same level (P = .788). No significant difference in shoulder ROM was found between preoperative and postoperative results. The Rowe and ASOSS scores showed statistical improvement after operation (P < .01). No significant difference in functional scores was found between the groups The Rowe score in the Bankart group increased from a preoperative mean (± SD) of 41 ± 13 points to 89.7 points postoperatively, and in the Latarjet group, from a preoperative mean of 42.5 ± 14 points to 88.4 points postoperatively (P = .95). The ASOSS score in the Bankart group increased from a preoperative mean of 53.3 ± 3 points to 93.3 ± 6 points postoperatively, and in the Latarjet group, from a preoperative mean of 53.1 ± 3 points to 93.7 ± 4 points postoperatively (P = .95). There were 18 recurrences (14%). The rate of recurrence was 20% in the Bankart group and 4% in the Latarjet group (P = .01). There were 15 reoperations (12%). The rate of reoperation was 16% in the Bankart group and 4% in the Latarjet group (P = .03). There were 6 complications (5%). The rate of complications was 4% in the Bankart group and 6% in the Latarjet group (P = .55). The proportion of postoperative osteoarthritis was 10% in the Bankart group (8/80 patients) and 12% (6/50 patients) in the Latarjet group (P = .55). CONCLUSION: In competitive rugby players with glenohumeral instability and a glenoid bone loss <20%, both the arthroscopic Bankart repair and the Latarjet procedure produced excellent functional outcomes, with most athletes returning to sport at the same level they had before the injury. However, the Bankart procedure was associated with a significantly higher rate of recurrence (20% vs 4%) and reoperation (16% vs 4%) than the Latarjet procedure.

Retorno al deporte luego de una cirugía de Latarjet: revisión sistemática de la bibliografía / Return to sports after Latarjet surgery: Systematic literature review

Introducción: El objetivo de este estudio fue describir las tasas de retorno al deporte y el nivel alcanzado por los pacientes con inestabilidad de hombro luego del procedimiento abierto y artroscópico de Latarjet. materiales y métodos:Seguimos un protocolo prespecificado y registrado en PROSPERO. Evaluamos la calidad de los estudios y utilizamos el sistema GRADE para evaluar la calidad general de la evidencia obtenida en los resultados. Incluimos estudios que evalúan el retorno al deporte de los pacientes luego de una cirugía de Latarjet con un seguimiento mínimo de 2 años. Resultados: Se incluyeron 24 estudios, con 1436 atletas, todos con cirugía y un seguimiento promedio de 57 meses (rango 24-240). La tasa general de retorno al deporte varió del 65% al 100% de los pacientes, de ellos, el 23-100% retornó al mismo nivel. El tiempo promedio de retorno al deporte fue de 6 meses (rango 1-36). El nivel de evidencia fue bajo debido a las características de los estudios incluidos (nivel de evidencia IV), las limitaciones de los estudios y sus inconsistencias. Conclusiones: La mayoría de los atletas con luxación recidivante de hombro sometidos a una cirugía de Latarjet retoman la práctica deportiva; sin embargo, el nivel alcanzado varía sustancialmente. El tiempo promedio de retorno al deporte fue de 6 meses, y no hubo diferencias significativas entre los deportistas competitivos y recreacionales. Nivel de Evidencia: IV

background: The purpose of this study was to describe rates of return to sports and the level achieved by patients after a Latarjet procedure.methods: We followed a protocol registered in PROSPERO (registration number CRD42018107606). A literature search was performed in May 2019 in MEDLINE, EMBASE, CENTRAL and clinical trials records. We used the GRADE approach for the assessment of the overall quality of the evidence per outcome. We included studies (evidence level I to IV) evaluating return to sports following shoulder stabilization with the Latarjet procedure with a minimum of 2-year follow-up. Results: We included 24 studies, including 1436 athletes, all treated surgically after an average follow-up of 57 months (range 24 to 240). The overall rate of return to sport ranged from 65% to 100%, including 23% to 100% at an equivalent level of play. The average time for return to sport was 6 months (range, 1 - 36 months). Competitive athletes appeared to return to the same level of competition and this difference was not statistically significant (p = 0.32). The quality of the evidence was very low due to study design (evidence level IV), study limitations and inconsistency. Conclusion: Most athletes with glenohumeral instability returned to sport, however the level maintained after shoulder stabilization with the Latarjet procedure varied substantially. The average time to return to sports was 6 months and results were equally favorable in competitive and recreational athletes

High Rate of Return to Sports and Low Recurrences With the Latarjet Procedure in High-Risk Competitive Athletes With Glenohumeral Instability and a Glenoid Bone Loss <20.

PURPOSE: To analyze return to sports, functional outcomes, and complications following the Latarjet procedure in competitive athletes with anterior glenohumeral instability and glenoid bone loss <20%. METHODS: All the included patients were operated between 2010 and 2016. The inclusion criteria were competitive athletes with anterior glenohumeral instability, a glenoid bone defect <20% who participated in contact sports, forced overhead sports, or had a previous failed Bankart repair and had a minimum 2 years' follow-up. Return to sports, range of motion (ROM), the Rowe score, and the Athletic Shoulder Outcome Scoring System score were used to assess functional outcomes. Complications and bone consolidation were also evaluated. RESULTS: A total of 65 athletes were included in the study. The mean follow-up was 53 months (±13), and the mean age was 23.9 years (range, 16-31 years). Overall, 94% were able to return to sports and 84% returned at the same level. No significant difference in shoulder ROM was found between preoperative and postoperative results. The Rowe and Athletic Shoulder Outcome Scoring System scores showed statistical improvement after operation (P < .001). No significant difference in shoulder ROM and functional scores was found between primary and revision cases. The total complication rate was 11% and the revision rate was 1.5% The recurrence rate was 4.6%. The bone block healed in 95% of the cases. CONCLUSIONS: In high-risk competitive athletes with anterior glenohumeral instability and glenoid bone loss <20%, the Latarjet procedure resulted in excellent functional outcomes, with most of the patients returning to sports and at the same level they had before injury with a low rate of recurrences. LEVEL OF EVIDENCE: Therapeutic case series; Level of evidence, IV.

High Variability in Functional Outcomes and Recurrences Between Contact Sports After Arthroscopic Bankart Repair: A Comparative Study of 351 Patients With a Minimum 3-Year Follow-Up.

PURPOSE: To compare return to sports, functional outcomes, and complications of a consecutive series of contact athletes with anterior glenohumeral instability treated with isolated arthroscopic Bankart repair for isolated anterior instability. METHODS: Between January 2008 and December 2016, 351 competitive athletes who participated in contact or collision sports underwent isolated arthroscopic Bankart repair at our institution (rugby n = 105, soccer n = 90, martial arts n = 36 boxing n = 28, field hockey n = 30, handball n = 31, and basketball n = 31). Return to sports, the Rowe score, and the Athletic Shoulder Outcome Scoring System (ASOSS) score were used to assess functional outcomes. Complications also were evaluated. RESULTS: The mean follow-up period was 66.7 months (range, 36-148 months) and the mean age of the 351 patients was 21.3 years (range, 17-30 years).Overall, 309 patients (88%) were able to return to sports, and 284 (81%) returned at the same level as before the injury. The mean time to return to sports was 5.3 months. The rate of return to sports, the level achieved by the patients, and time to return to sports varied significantly between sports. The Rowe and ASOSS scores showed statistical improvement after operation (P < .001). The ASOSS score varied significantly between sports (P < .001). There were 40 recurrences (11.3%), 7 complications (2%) and 21 patients (6%) underwent revision surgery. There was a significant difference in the rate of recurrences and revisions between the different contact sports. CONCLUSIONS: In athletes with glenohumeral instability who undergo isolated arthroscopic Bankart repair for isolated anterior instability, there is great variability in the rate of return to sport at the same level, in shoulder performance after returning to competition, and in the postoperative recurrence rates. Due to the high variability found in our study, results after arthroscopic Bankart repair in contact athletes should not be reported globally by including the different sports under the "collision or contact sports" label. LEVEL OF EVIDENCE: Retrospective Case Series; Level of evidence, 4.

Are the Classic and the Congruent Arc Latarjet Procedures Equally Effective for the Treatment of Recurrent Shoulder Instability in Athletes?

BACKGROUND: There is a lack of evidence in the literature comparing outcomes between the classic and the congruent arc Latarjet procedures in athletes. PURPOSE: To compare return to sports, functional outcomes, and complications between the classic and the congruent arc Latarjet procedures in athletes with recurrent glenohumeral instability. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Between June 2009 and June 2017, 145 athletes with recurrent anterior glenohumeral instability underwent surgery with the Latarjet as a primary procedure in our institution. The classic procedure was used in 66 patients, and the congruent arc method was used in 79 patients. Return to sports, range of motion (ROM), the Rowe score, a visual analog scale (VAS) for pain in sports activity, and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. Recurrences were also evaluated. The postoperative bone block position and consolidation were assessed with computed tomography. RESULTS: In the total population, the mean follow-up was 41.3 months (range, 24-90 months) and the mean age was 25.3 years (range, 18-45 years). In total, 90% of patients were able to return to sports; of these, 91% returned at their preinjury level of play. No significant difference in shoulder ROM was found between preoperative and postoperative results. The Rowe, VAS, and ASOSS scores showed statistical improvement after operation (P < .001). The Rowe score increased from a preoperative mean of 42.8 points to a postoperative mean of 95.2 points (P < .01). Subjective pain during sports improved from 3.2 points preoperatively to 0.7 points at last follow-up (P < .01). The ASOSS score improved significantly from a preoperative mean of 46.4 points to a postoperative mean of 88.4 points (P < .01). No significant differences in shoulder ROM and functional scores were found between patients who received the classic vs congruent arc procedures. There were 5 recurrences (3.5%): 3 dislocations (2%) and 2 subluxations (1%). No significant difference in the recurrence rate was noted between groups. The bone block healed in 134 cases (92%). CONCLUSION: In athletes with recurrent anterior glenohumeral instability, the Latarjet procedure produced excellent functional outcomes. Most athletes returned to sports at their preinjury level, and the rate of recurrence was very low, regardless of whether the patients received surgery with the classic or congruent arc technique.
