ABSTRACT
BACKGROUND: The purpose of this study was to determine the short-term outcomes for patients who underwent revision surgery for shoulder instability, including both revision arthroscopic repair and Latarjet. METHODS: This study included patients who underwent revision of a prior arthroscopic labral repair to arthroscopic labral repair or Latarjet at our institution from 2012 to 2017. After collection of preoperative demographic data, preoperative 3-dimensional imaging was reviewed to determine percent glenoid bone loss (%GBL) and to determine whether each shoulder was on-track or off-track. Patients were contacted to obtain postoperative patient-reported outcome metrics including visual analog scale pain, Simple Shoulder Test, American Shoulder and Elbow Surgeons scores, and instability recurrence (full dislocation, subluxation, or subjective apprehension) data at a minimum of 2 years postoperatively. RESULTS: Of 62 patients who met criteria, 45 patients were able to be contacted. Of them, 21 underwent revision arthroscopy and 24 underwent a Latarjet procedure. In the revision arthroscopy group, 5 of 15 had %GBL >20% and 4 of 21 were contact athletes. In the Latarjet group, 11 of 22 had %GBL >20% and 5 of 24 were contact athletes. Of 21 revision arthroscopy patients, 8 underwent concomitant remplissage. Eight of 21 patients in the revision arthroscopy group and 7 of 21 patients in the Latarjet group reported instability postoperatively. Three of 21 patients in the revision arthroscopy group and 2 of 21 patients in the Latarjet group reported full dislocations postoperatively. Zero patients in the revision arthroscopy group and 1 of 21 patients in the Latarjet group underwent reoperation. CONCLUSION: Our results suggest that both revision Latarjet and arthroscopic stabilization can be of benefit in select circumstances. However, in revision settings, postoperative instability symptoms are common with both procedures.
ABSTRACT
BACKGROUND: The purposes of this study were to determine whether acromial morphology (1) could be measured accurately on magnetic resonance images (MRIs) as compared to computed tomographs (CTs) as a gold standard, (2) could be measured reliably on MRIs, (3) differed between patients with rotator cuff tears (RCTs) and those without evidence of RCTs or glenohumeral osteoarthritis, and (4) differed between patients with rotator cuff repairs (RCRs) that healed and those that did not. METHODS: This is a retrospective comparative study. We measured coronal, axial, and sagittal acromial tilt; acromial width, acromial anterior and posterior coverage, and glenoid version and inclination on MRI corrected into the plane of the glenoid. We determined accuracy by comparison with CT via intraclass correlation coefficients (ICCs). To determine reliability, these same measurements were made on MRI by 2 observers and ICCs calculated. We compared these measurements between patients with a full-thickness RCT and patients aged >50 years without evidence of an RCT or glenohumeral osteoarthritis. We then compared these measurements between those patients with healed RCRs and those with a retorn rotator cuff on MRI. In this portion, we only included patients with both a preoperative MRI and a postoperative MRI at least 1 year from RCR. Only those patients without tendon defects on postoperative MRIs were considered to be healed. In these patients, we also radiographically measured the critical shoulder angle. RESULTS: In a validation cohort of 30 patients with MRI and CT, all ICCs were greater than 0.86. In these patients, the inter-rater ICCs of the MRI measurements were >0.53. In our RCT group of 110 patients, there was greater acromial width [mean difference (95% confidence interval) = 0.1 (0, 0.2) mm, P = .012] and significantly less sagittal acromial tilt [9° (5°-12°), P < .001] than in our comparison group of 107 patients. A total of 110 RCRs were included. Postoperative MRI scans were obtained at a mean follow-up of 24.2 ± 15.8 months, showing 84 patients (76%) had healed RCRs. Aside from acromial width, which was 0.2 mm different and thus did not have clinical significance, there was no association between healing and any of the measured morphologic characteristics. Patients with healed repairs had significantly smaller tears in terms of both width (P < .001) and retraction (P < .001). CONCLUSION: Although the acromion is wider in RCTs, the difference of 0.1 mm likely has no clinical significance. The acromion is more steeply sloped from posteroinferior to anterosuperior in those with RCTs. These findings call into question subacromial impingement due to native acromial morphology as a cause of rotator cuff tearing. Acromial morphology, critical shoulder angle, and glenoid inclination were not associated with healing after RCR. This study does not support lateral acromioplasty.

¼ Injuries to the posterior root of the lateral meniscus occur frequently in acute knee injuries with concomitant tearing of the anterior cruciate ligament (ACL). ¼ The meniscofemoral ligaments (MFLs), consisting of the anterior MFL (ligament of Humphrey) and the posterior MFL (ligament of Wrisberg), as well as the osseous attachment of the meniscal root, stabilize the lateral meniscus, enabling appropriate load transmission and maintenance of contact forces within the lateral compartment of the knee during loading and range of motion. ¼ In the setting of an ACL injury to the knee with osseous root injury of the posterior root of the lateral meniscus, the MFLs (when present) may stabilize the lateral meniscus against meniscal extrusion, thereby maintaining appropriate contact mechanics within the knee, decreasing the risk of subsequent chondral and meniscal injury and the development of premature osteoarthritis. ¼ Additional study on the indications for posterior meniscal root repair during ACL reconstruction is warranted since the ideal management of lateral root injury in the MFL-intact knee remains unknown.

BACKGROUND: Minimal clinically important differences (MCIDs) for different patient outcome scores have been reported for various shoulder diseases, including shoulder arthroplasty and the nonoperative treatment of rotator cuff disease. The purpose of this study was to assess the MCID for the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score, the Simple Shoulder Test (SST), and a visual analog scale (VAS) measuring pain, after arthroscopic rotator cuff repair. METHODS: A total of 202 patients who underwent arthroscopic rotator cuff repair were retrospectively reviewed. ASES, SST, and VAS pain scores were collected preoperatively and at 1 year postoperatively. The MCID was then calculated via a 4-question anchor-based method. RESULTS: The MCID results for the ASES, SST, and VAS pain scores were 27.1, 4.3, and 2.4, respectively. Age at time of surgery, sex, anteroposterior tear size, and worker's compensation status were not associated with MCID values (P > .05). CONCLUSION: The MCID values determined in the current study are higher than those previously identified for the nonoperative treatment of rotator cuff disease using the same anchor questions. Use of these higher values should be considered when evaluating improvements of individual patients after rotator cuff repair, to determine comparative effectiveness of various rotator cuff repair techniques and to determine sample sizes for prospective comparative trials of rotator cuff repair methods.

BACKGROUND: The optimal surgical treatment of anterior shoulder instability remains controversial. HYPOTHESIS: (1) Implants and facility-related costs are the primary drivers of variation in direct costs between arthroscopic Bankart and Latarjet procedures, and (2) distal tibial allograft (DTA) is more costly than Latarjet as a function of the graft expense. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: Intraoperative cost data were derived for all arthroscopic anterior stabilizations and Latarjet and DTA procedures performed at a single academic institution from January 2012 to September 2017. Cost comparisons were made between those undergoing arthroscopic stabilization and Latarjet and between Latarjet and DTA. Multivariate regressions were performed to determine the difference in direct costs accounting for various patient- and surgery-related factors. RESULTS: A total of 87 arthroscopic stabilizations, 44 Latarjet procedures, and 5 DTA procedures were performed during the study period. Arthroscopic Bankart repair was found to be 17% more costly than Latarjet, with suture anchor implant cost being the primary driver of cost. DTA was 2.9-fold more costly than Latarjet, with greater costs across all domains. Multivariate analysis also found the number of prior arthroscopic procedures performed (P = .007) and whether the procedure was performed in an ambulatory or inpatient setting (P < .0001) to be significantly associated with higher direct costs. CONCLUSION: Latarjet is less costly than arthroscopic Bankart repair, largely because of implant cost. Value-driven strategies to narrow the cost differential could focus on performing these procedures in an outpatient setting in addition to reducing overall implant cost for arthroscopic procedures. Perceived potential benefits of DTA over Latarjet may be outweighed by higher costs.
ABSTRACT
BACKGROUND: Few studies have investigated the influence of patient-specific variables or procedure-specific factors on the overall cost of anterior cruciate ligament reconstruction (ACLR) in an ambulatory surgery setting. PURPOSE: To determine patient- and procedure-specific factors influencing the overall direct cost of outpatient arthroscopic ACLR utilizing a unique value-driven outcomes (VDO) tool. STUDY DESIGN: Cohort study (economic and decision analysis); Level of evidence, 3. METHODS: All ACLRs performed by 4 surgeons over 2 years were retrospectively reviewed. Cost data were derived from the VDO tool. Patient-specific variables included age, body mass index, comorbidities, American Society of Anesthesiologists (ASA) classification, smoking status, preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function Computerized Adaptive Testing (PF-CAT) score, and preoperative Single Assessment Numeric Evaluation (SANE) score. Procedure-specific variables included graft type, revision status, associated injuries and procedures, time from injury to ACLR, surgeon, and operating room (OR) time. Multivariate analysis determined patient- and procedure-related predictors of total direct costs. RESULTS: There were 293 autograft reconstructions, 110 allograft reconstructions, and 31 hybrid reconstructions analyzed. Patient-specific factors did not significantly influence the ACLR cost. The mean OR time was shorter for allograft reconstruction (P < .001). Predictors of an increased direct cost included the use of an allograft or hybrid graft (44.5% and 33.1% increase, respectively; P < .001), increased OR time (0.3% increase per minute; P < .001), surgeon 3 or 4 (9.1% or 5.9% increase, respectively; P < .001 or P = .001, respectively), and concomitant meniscus repair (24.4% increase; P < .001). Within the meniscus repair cohort, all-inside, root, and combined repairs correlated with a 15.5%, 31.4%, and 53.2% increased mean direct cost, respectively, compared with inside-out repairs (P < .001). CONCLUSION: This study failed to identify modifiable patient-specific factors influencing direct costs of ACLR. Allografts and hybrid grafts were associated with an increased total direct cost. Meniscus repair independently predicted an increased direct cost, with all-inside, root, and combined repairs being costlier than inside-out repairs. The time-saving potential of all-inside meniscus repair was not realized in this study, making implant use a significant factor in the overall cost of ACLR with meniscus repair.
ABSTRACT
BACKGROUND: Very limited information exists about factors affecting direct clinical costs of rotator cuff repair surgery. The purpose of this study was to determine the direct cost of outpatient arthroscopic rotator cuff repair surgery using a unique value-driven outcomes tool and to identify patient- and treatment-related variables affecting cost. METHODS: Cost data were derived for arthroscopic rotator cuff repairs performed by 3 surgeons from March 2014 to June 2015 using the value-driven outcomes tool. Costs included overall total direct cost, which included facility utilization costs, medication costs, supply costs, and other ancillary costs. Univariate and multivariate regressions were performed to determine the effect of various patient-related and surgical-related factors on costs. RESULTS: There were 170 arthroscopic rotator cuff repairs performed during the study period. Multivariate analysis showed significant correlations between higher total direct cost and the presence of a subscapularis repair being performed (P = .015) and total number of anchors used (P < .0001). Higher body mass index, severe systemic illness, 1 of the 3 surgeons, biceps tenodesis using an anchor, and total sum of anchors were correlated with higher facility utilization costs (P < .04). Severe systemic illness, addition of a subscapularis repair, 1 of the 3 surgeons, and additional subacromial decompression were correlated with higher pharmacy costs (P < .006). The addition of a subscapularis repair, total sum of anchors, and severe muscle changes to the supraspinatus were correlated with higher supply costs (P < .015). CONCLUSIONS: From a direct cost perspective, implementation of strategies to reduce overall costs should focus on reducing overall anchor quantity or price.

BACKGROUND: Recent attention has focused on the optimal surgical treatment for recurrent shoulder instability in young athletes. Collision athletes are at a higher risk for recurrent instability after surgery. PURPOSE: To evaluate variables affecting return-to-play (RTP) rates in Division I intercollegiate football athletes after shoulder instability surgery. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Invitations to participate were made to select sports medicine programs that care for athletes in Division I football conferences (Pac-12 Conference, Southeastern Conference [SEC], Atlantic Coast Conference [ACC]). After gaining institutional review board approval, 7 programs qualified and participated. Data on direction of instability, type of surgery, time to resume participation, and quality and level of play before and after surgery were collected. RESULTS: There were 168 of 177 procedures that were arthroscopic surgery, with a mean 3.3-year follow-up. Overall, 85.4% of players who underwent arthroscopic surgery without concomitant procedures returned to play. Moreover, 15.6% of athletes who returned to play sustained subsequent shoulder injuries, and 10.3% sustained recurrent instability, resulting in reduction/revision surgery. No differences were noted in RTP rates in athletes who underwent anterior labral repair (82.4%), posterior labral repair (92.9%), combined anterior-posterior repair (84.8%; P = .2945), or open repair (88.9%; P = .9362). Also, 93.3% of starters, 95.4% of utilized players, and 75.7% of rarely used players returned to play. The percentage of games played before the injury was 49.9% and rose to 71.5% after surgery ( P < .0001). Athletes who played in a higher percentage of games before the injury were more likely to return to play; 91% of athletes who were starters before the injury returned as starters after surgery. Scholarship status significantly correlated with RTP after surgery ( P = .0003). CONCLUSION: The majority of surgical interventions were isolated arthroscopic stabilization procedures, with no statistically significant difference in RTP rates when concomitant arthroscopic procedures or open stabilization procedures were performed. Athletes who returned to play often played in a higher percentage of games after surgery than before the injury, and many played at the same or a higher level after surgery.

PURPOSE: The primary purpose of this study was to determine the effect of the preoperative position of the musculotendinous junction (MTJ) on rotator cuff healing after double-row arthroscopic rotator cuff repair. A secondary purpose was to evaluate how tendon length and MTJ position change when the rotator cuff heals. METHODS: Preoperative and postoperative magnetic resonance imaging (MRI) scans of 42 patients undergoing arthroscopic double-row rotator cuff repair were reviewed. Patients undergoing repairs with other constructs or receiving augmented repairs (platelet-rich fibrin matrix) who had postoperative MRI scans were excluded. Preoperative MRI scans were evaluated for anteroposterior tear size, tendon retraction, tendon length, muscle quality, and MTJ position with respect to the glenoid in the coronal plane. The position of the MTJ was referenced off the glenoid face as either lateral or medial. Postoperative MRI scans were evaluated for healing, tendon length, and MTJ position. RESULTS: Of 42 tears, 36 (86%) healed, with 27 of 31 small to medium tears (87%) and 9 of 11 large to massive tears (82%) healing. Healing occurred in 94% of tears that had a preoperative MTJ lateral to the face of the glenoid but only 56% of tears that had a preoperative MTJ medial to the glenoid face (P = .0135). The measured tendon length increased an average of 14.4 mm in patients whose tears healed compared with shortening by 6.4 mm in patients with tears that did not heal (P < .001). The MTJ lateralized an average of 6.1 mm in patients whose tears healed compared with medializing 1.9 mm in patients whose tears did not heal (P = .026). The overall follow-up period of the study was from April 2005 to September 2014 (113 months). CONCLUSIONS: The preoperative MTJ position is predictive of postoperative healing after double-row rotator cuff repair. The position of the MTJ with respect to the glenoid face is a reliable, identifiable marker on MRI scans that can be predictive of healing. LEVEL OF EVIDENCE: Level IV, retrospective review of case series; therapeutic study.

PURPOSE: To evaluate the convergent validity, precision, and completion times for the Physical Function Computerized Adaptive Test (PF-CAT) in a sports medicine patient population relative to standard measures of knee and shoulder function. METHODS: We reviewed all patient visits from April through September 2014 with either knee or shoulder complaints from a university-based sports medicine clinic, during which PF-CAT, Single Assessment Numerical Evaluation (SANE), Simple Shoulder Test (SST), and American Shoulder and Elbow Surgeons (ASES) outcome scores for shoulder patients and PF-CAT, SANE, and International Knee Documentation Committee (IKDC) scores for knee patients were obtained, with an initial visit or one follow-up visit included in the study. Spearman correlation was used to evaluate pairwise agreement among scores. The McNemar χ2 test was used to evaluate a difference in the number of times floor and ceiling values occurred. Wilcoxon signed rank tests were used to compare differences in completion times. RESULTS: In total, 415 shoulder and 450 knee clinical evaluations qualified for inclusion in the study. A high correlation was found between IKDC and PF-CAT scores (r = 0.75, P < .0001), and a moderately high correlation was found between PF-CAT and both SST (r = 0.68, P < .0001) and ASES (r = 0.63, P < .0001) scores. Maximum differences in the sum of floor-ceiling values versus the PF-CAT were 15% for the SST (P < .0001), 2.5% for the ASES (ceiling only, P = .0133), and 5.8% for the shoulder SANE (floor P = .0012, ceiling P = .0269). The PF-CAT had values of 0.4% for the shoulder and 0.6% for the knee. Zero percent of IKDC scores but 6.9% of knee SANE scores hit floor or ceiling values (floor P = .0019, ceiling P = .0007). The PF-CAT median completion time was lower at 55 seconds versus 268 seconds for the IKDC assessment (P < .0001), whereas shoulder patients' times were 61, 139, and 116 seconds for the PF-CAT, SST, and ASES evaluation, respectively (P < .0001). CONCLUSIONS: The PF-CAT showed a high correlation with IKDC scores and a moderately high correlation with ASES and SST outcomes. The PF-CAT takes significantly less time to complete and exhibits improved or similar floor and ceiling effects in comparison to IKDC, SST, and ASES scores. The PF-CAT can be used in evaluating sports medicine knee and shoulder patients. LEVEL OF EVIDENCE: Level III, cross-sectional study.

Reported rates of venous thromboembolism (VTE) after shoulder arthroplasty (SA) range from 0.2% to 13%. Few studies have evaluated the incidence of VTE in a large patient population from a single institution. We conducted a study to determine the incidence of VTE (deep venous thrombosis [DVT] and pulmonary embolism [PE]) in a large series of SAs. Cases of SAs performed at our institution between January 1999 and May 2012 were retrospectively reviewed for development of symptomatic VTE within the first 90 days after surgery. During the study period, 533 SAs (245 anatomical total SAs [TSAs], 112 reverse TSAs, 92 hemiarthroplasties, 84 revision SAs) were performed. Logistic regression analyses were used to evaluate the association of various risk factors with VTE. For the 533 SAs, the symptomatic VTE rate was 2.6% (14 patients), the DVT rate was 0.9% (5), and the PE rate was 2.3% (12). Risk factors significantly correlated with a thrombotic event included raised Charlson Comorbidity Index, preoperative thrombotic event, lower preoperative hemoglobin and hematocrit levels, diabetes, lower postoperative hemoglobin level, use of general endotracheal anesthesia without interscalene nerve block, higher body mass index, and revision SA (P < .05). Our rates of symptomatic VTE events (DVT, PE) after SA are relatively low, though they are higher than the rates in studies that have used large state or national databases. Risk factors associated with thrombosis can be useful in identifying patients at risk for clotting after SA.

BACKGROUND: Patients with shoulder and rotator cuff pathology who exhibit greater levels of psychological distress report inferior preoperative self-assessments of pain and function. In several other areas of orthopaedics, higher levels of distress correlate with a higher likelihood of persistent pain and disability after recovery from surgery. To our knowledge, the relationship between psychological distress and outcomes after arthroscopic rotator cuff repair has not been similarly investigated. QUESTIONS/PURPOSES: (1) Are higher levels of preoperative psychological distress associated with differences in outcome scores (visual analog scale [VAS] for pain, Simple Shoulder Test, and American Shoulder and Elbow Surgeons score) 1 year after arthroscopic rotator cuff repair? (2) Are higher levels of preoperative psychological distress associated with less improvement in outcome scores (VAS for pain, Simple Shoulder Test, and American Shoulder and Elbow Surgeons score) 1 year after arthroscopic rotator cuff repair? (3) Does the prevalence of psychological distress in a population with full-thickness rotator cuff tears change when assessed preoperatively and 1 year after arthroscopic rotator cuff repair? METHODS: Eighty-five patients with full-thickness rotator cuff tears were prospectively enrolled; 70 patients (82%) were assessed at 1-year followup. During the study period, the three participating surgeons performed 269 rotator cuff repairs; in large part, the low overall rate of enrollment was related to two surgeons enrolling only two patients total in the initial 14 months of the study. Psychological distress was quantified using the Distress Risk Assessment Method questionnaire, and patients completed self-assessments including the VAS for pain, the Simple Shoulder Test, and the American Shoulder and Elbow Surgeons score preoperatively and 1 year after arthroscopic rotator cuff repair. Fifty of 85 patients (59%) had normal levels of distress, 26 of 85 (31%) had moderate levels of distress, and nine of 85 (11%) had severe levels of distress. Statistical models were used to assess the effect of psychological distress on patient self-assessment of shoulder pain and function at 1 year after surgery. RESULTS: With the numbers available, distressed patients were not different from nondistressed patients in terms of postoperative VAS for pain (1.9 [95% confidence interval {CI}, 1.0-2.8] versus 1.0 [95% CI, 0.5-1.4], p = 0.10), Simple Shoulder Test (9 [95% CI, 8.1-10.4] versus 11 [95% CI, 10.0-11.0], p = 0.06), or American Shoulder and Elbow Surgeons scores (80 [95% CI, 72-88] versus 88 [95% CI, 84-92], p = 0.08) 1 year after arthroscopic rotator cuff repair. With the numbers available, distressed patients also were not different from nondistressed patients in terms of the amount of improvement in scores between preoperative assessment and 1-year followup on the VAS for pain (3 [95% CI, 2.2-4.1] versus 2 [95% CI, 1.4-2.9], p = 0.10), Simple Shoulder Test (5.2 [95% CI, 3.7-6.6] versus 5.0 [95% CI, 4.2-5.8], p = 0.86), or American Shoulder and Elbow Surgeons scale (38 [95% CI, 29-47] versus 30 [95% CI, 25-36], p = 0.16). The prevalence of psychological distress in our patient population was lower at 1 year after surgery 14 of 70 (20%) versus 35 of 85 (41%) preoperatively (odds ratio, 0.36; 95% CI, 0.17-0.74; p = 0.005). CONCLUSIONS: Mild to moderate levels of distress did not diminish patient-reported outcomes to a clinically important degree in this small series of patients with rotator cuff tears. This contrasts with reports from other areas of orthopaedic surgery and may be related to a more self-limited course of symptoms in patients with rotator cuff disease or possibly to a beneficial effect of rotator cuff repair on sleep quality or other unrecognized determinants of psychosocial status. LEVEL OF EVIDENCE: Level I, prognostic study.

STUDY OBJECTIVE: The femoral, lateral femoral cutaneous, and obturator nerves (ONs) can reportedly be blocked using a single-injection deep to the fascia iliaca (FI) at the level of the inguinal ligament. Two commonly used methods (the FI compartment and 3-in-1 blocks) have produced inconsistent results with respect to local anesthetic distribution and effect on the ON. To date, no study of either method has been performed using advanced imaging techniques to document both needle placement and local anesthetic distribution. We report the outcome of a series of 3-in-1 and FI blocks performed using ultrasound to guide needle position and magnetic resonance imaging (MRI) to define local anesthetic distribution. DESIGN: Patients were prospectively studied, and images were interpreted using a randomized and blinded protocol. SETTING: The study was performed in the perioperative area of an academic orthopedic specialty hospital. PATIENTS: Ten patients (ASA 1-2) having anterior cruciate ligament reconstruction received either 3-in-1 or FI compartment blocks for postoperative analgesia using the surface landmarks described for these techniques. INTERVENTIONS: Ultrasound was used to position the injecting needle immediately deep to the FI. Local anesthetic distribution was studied using MRI. MEASUREMENTS: Patients were examined for motor and/or sensory function of the femoral, obturator, and lateral femoral cutaneous nerves. Magnetic resonance imaging was used to document the limits of injectate distribution. MAIN RESULTS: Magnetic resonance imaging showed distribution of injectate over the surface of the iliacus and psoas muscles to the level of the retroperitoneum. No patient showed medial extension of injectate to the ON. At the level of the inguinal ligament, injectate extended laterally toward the anterior superior iliac spine and medially to the femoral vein. All patients had significant weakness with extension of the knee and sensory loss over the anterior, lateral, and medial thigh. No patient demonstrated decreased hip adductor strength. CONCLUSIONS: Ultrasound and MRI show consistent superior extension of local anesthetic to the level of the retroperitoneum for both techniques. There was reliable clinical effect on the femoral and lateral femoral cutaneous nerves. However, none of the injections produced evidence of ON block either at the level of the retroperitoneum or the inguinal ligament.

BACKGROUND: In many areas of orthopaedics, patients with greater levels of psychological distress report inferior self-assessments of pain and function. This effect can lead to lower-than-expected baseline scores on common patient-reported outcome scales, even those not traditionally considered to have a psychological component. QUESTIONS/PURPOSES: This study attempts to answer the following questions: (1) Are higher levels of psychological distress associated with clinically important differences in baseline scores on the VAS for pain, the Simple Shoulder Test, and the American Shoulder and Elbow Surgeons score in patients undergoing arthroscopic rotator cuff repair? (2) Does psychological distress remain a negative predictor of baseline shoulder scores when other clinical variables are controlled? METHODS: Eighty-five patients with full-thickness rotator cuff tears were prospectively enrolled. Psychological distress was quantified using the Distress Risk Assessment Method questionnaire. Patients completed baseline self-assessments including the VAS for pain, the Simple Shoulder Test, and the American Shoulder and Elbow Surgeons score. Age, sex, BMI, smoking status, American Society of Anesthesiologists classification, tear size, and tear retraction were recorded for each patient. Bivariate correlations and multivariate regression models were used to assess the effect of psychological distress on patient self-assessment of shoulder pain and function. RESULTS: Distressed patients reported higher baseline VAS scores (6.7 [95% CI, 4.4-9.0] versus 2.9 [95% CI, 2.3-3.6], p = 0.001) and lower baseline Simple Shoulder Test (3.7 [95% CI, 2.9-4.5] versus 5.7 [95% CI 5.0-6.4], p = 0.001) and American Shoulder and Elbow Surgeons scores (39 [95% CI, 34-45] versus 58 [95% CI, 53-63], p < 0.001). Distress remained associated with higher VAS scores (p = 0.001) and lower Simple Shoulder Test (p < 0.001) and American Shoulder and Elbow Surgeons scores (p < 0.001) when age, sex, BMI, American Society of Anesthesiologists classification, smoking status, tear size, and tear retraction were controlled. CONCLUSIONS: Higher levels of psychological distress are associated with inferior baseline patient self-assessment of shoulder pain and function using the VAS, the Simple Shoulder Test, and the American Shoulder and Elbow Surgeons score. Longitudinal followup is warranted to clarify the relationship between distress and self-perceived disability and the effect of distress on postoperative outcomes after arthroscopic rotator cuff repair. LEVEL OF EVIDENCE: Level I, prognostic study. See the Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: For competitive athletes, return to play (RTP) and return to preinjury levels of performance after anterior cruciate ligament (ACL) reconstruction are the main goals of surgery. Although outcomes of ACL surgery are well studied, details on factors influencing RTP in elite college football players have not been evaluated thoroughly. PURPOSE: To determine the rate of RTP following ACL surgery among National Collegiate Athletic Association (NCAA) Division 1 collegiate football athletes and to examine variables that may affect these rates. The hypothesis was that the RTP rate in this cohort will be influenced by factors reflecting skill and accomplishment; that is, athletes higher on the depth chart, those on scholarship, and those later in their careers will have higher RTP rates. It was also predicted that graft type and concomitant procedures may have an effect on RTP rates. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Using athlete- and surgery-specific data from participating institutions in 3 major Division 1 college football conferences, information on athletes who had ACL reconstruction from 2004 through 2010 was collected. Statistical analyses were performed to determine the RTP rate as a function of the variables, such as depth chart position, in the data collected. RESULTS: Of the 184-player cohort, 82% of the athletes, including 94% of starters, were able to RTP. Rates were greater among athletes higher on the depth chart (P = .004) and on scholarship (P = .008). Year of eligibility also affected RTP rates (P = .047), which increased from the redshirt and freshman year to the sophomore and junior years, but then decreased slightly into the senior and fifth-year senior seasons. The use of an autograft versus allograft was associated with increased RTP (P = .045). There was no significant difference (P = .18) between players who underwent an isolated ACL reconstruction versus those who underwent additional procedures. CONCLUSION: More than 80% of football players at the Division 1 level were able to RTP following ACL reconstruction. Factors representative of a player's skill were associated with higher rates of RTP. Surgery-specific variables, in general, had no effect on RTP, except for the use of autograft, which was associated with a greater RTP rate.
ABSTRACT
PURPOSE: The purpose of this study was to evaluate the correlation of rotator cuff musculotendinous junction (MTJ) retraction with healing after rotator cuff repair and with preoperative sagittal tear size. METHODS: We reviewed preoperative and postoperative magnetic resonance imaging (MRI) studies of 51 patients undergoing arthroscopic single-row rotator cuff repair between March 1, 2005, and February 20, 2010. Preoperative MRI studies were evaluated for anteroposterior tear size, tendon retraction, tendon length, muscle quality, and MTJ position with respect to the glenoid. The position of the MTJ was referenced off the glenoid face as either lateral or medial. Postoperative MRI studies obtained at a minimum of 1 year postoperatively (mean, 25 ± 13.9 months) were evaluated for healing, tendon length, and MTJ position. RESULTS: We found that 39 of 51 tears (76%) healed, with 26 of 30 small/medium tears (87%) and 13 of 21 large/massive tears (62%) healing. Greater tendon retraction, worse preoperative muscle quality, and a more medialized MTJ were all associated with worse tendon healing (P < .05). Of tears that had a preoperative MTJ lateral to the face of the glenoid, 93% healed, whereas only 55% of tears that had a preoperative MTJ medial to the face of the glenoid healed (P < .05). Healed repairs that had limited tendon lengthening (<1 cm) and limited MTJ position change (<1 cm) from preoperative were found to be smaller, had less preoperative tendon retraction, had less preoperative MTJ medialization, and had less preoperative rotator cuff fatty infiltration (P < .05). CONCLUSIONS: Preoperative MTJ medialization, tendon retraction, and muscle quality are all predictive of tendon healing postoperatively when using a single-row rotator cuff repair technique. The position of the MTJ with respect to the glenoid face can be predictive of healing, with over 90% healing if lateral and 50% if medial to the face. Lengthening of the tendon accounts for a significant percentage of the musculotendinous unit lengthening that occurs in healed tears as opposed to muscle elongation. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

A patient who manifested signs of serotonin syndrome during an intravenous anesthetic with remifentanil and propofol is presented. The patient displayed lower extremity clonus, nystagmus, and diaphoresis. At the time of surgery, the patient was being treated with fluoxetine (a selective serotonin reuptake inhibitor). A presumptive diagnosis of serotonin syndrome was made intraoperatively and all opioids were discontinued. His symptoms resolved in the Postanesthesia Care Unit without incident.

BACKGROUND: Interscalene brachial plexus block (ISBPB) provides excellent analgesia after rotator cuff surgery but is associated with diaphragm dysfunction. In this study, ISBPB with 20 mL of 0.125% or 0.25% bupivacaine were compared to assess the effect on diaphragm function, oxygen saturation, pain control, opioid requirements, and patient satisfaction. MATERIALS AND METHODS: In this prospective, randomized, double-blind study, 30 adults undergoing outpatient arthroscopic rotator cuff repair were enrolled to receive ultrasound-guided interscalene brachial plexus catheter placement with 20 mL of 0.125% (n = 15) or 0.25% bupivacaine (n = 15). Diaphragm function and oxygen saturation were assessed before ISBPB placement and on discharge from the postanesthesia care unit. Postoperative pain scores, opioid requirements, and patient satisfaction were compared. RESULTS: Diaphragm function and oxygen saturation were superior in the low concentration group. Absent or paradoxic motion of the diaphragm was present in 78% of the 0.25% group compared with 21% of patients in the 0.125% group (P = .008). Oxygen saturation decreased 4.3% in the 0.25% group compared with a decrease of 2.6% in the 0.125% group (P = .04). Pain scores averaged 1 of 10 in the 0.25% group and 0 of 10 in the 0.125% group (P = .02). Opioid requirements and patient satisfaction were not different between the two groups. CONCLUSIONS: In this randomized, double-blind comparison of ISBPB performed with 20 mL of 0.125% or 0.25% bupivacaine, diaphragm function and oxygen saturation were superior in patients treated with more dilute bupivacaine. Furthermore, there were no clinically significant differences in pain scores, and no statistically significant differences in opioid requirements and patient satisfaction.

BACKGROUND: Studies have reported high rates of transfusion in shoulder arthroplasty. This study was conducted to evaluate the rate of transfusion at our institution, to confirm reported risk factors for transfusion, and to look for changes over time.We hypothesized that transfusion rates associated with shoulder arthroplasty at our institution are lower than those recently reported and that the incidence of transfusion is higher in individuals with low preoperative hemoglobin, with revision arthroplasty, and in older individuals. MATERIALS AND METHODS: A retrospective review of 366 shoulder arthroplasties (323 patients) was performed. This included total shoulder arthroplasties, hemiarthroplasties, revision arthroplasties, and reverse total shoulder arthroplasties. Logistic regression analysis evaluated the association of clinical variables with transfusion. Early (1996-2005) and late (2006-2009) groups were compared to evaluate changes in demographics and transfusion rates over time. RESULTS: The overall transfusion rate was 7.4% (27 of 339). Predictors of transfusion were higher intraoperative blood loss, low preoperative hemoglobin level, and humeral cement fixation. Procedure type was not predictive of transfusion. There was no difference in transfusion rates between the early and late groups, but the late group had an increased use of general anesthesia combined with a regional block, increased intraoperative blood loss, and increased use of sequential compression devices for venous thromboembolism prophylaxis. CONCLUSIONS: Lower preoperative hemoglobin, higher intraoperative blood loss, and humeral cement fixation were predictors of transfusion, but not female sex, increasing age, type of procedure, or comorbidities.

PURPOSE: To analyze and compare the direct costs, reimbursement rates, gross contribution margins, and operating room and recovery room times for anterior cruciate ligament (ACL) reconstructions with the use of soft-tissue allografts and autografts. We aimed to determine the financial impact of using allograft tissue for ACL reconstruction in a hospital-based outpatient setting. METHODS: Financial data from the facility billing database and operating room (OR) reports from the electronic medical record were queried to identify all patients undergoing arthroscopic ACL reconstruction during a 12-month period. A subset of patients who had isolated ACL reconstruction with or without simple meniscectomy or chondral debridement was identified as the study group. We compared 46 ACL reconstructions using tibialis anterior or posterior allografts and 50 ACL reconstructions using hamstring autografts. Facility direct cost, reimbursement rates, gross contribution margin, OR times, and other variables were compared. RESULTS: The facility mean direct cost for ACL reconstruction using allografts was $4,587, with a mean OR time of 92 minutes. The mean direct cost and OR time for ACL reconstruction using autografts were $3,849 and 125 minutes, respectively. Allograft ACL reconstructions were $738 more costly, and reimbursement was also higher. Allograft ACL reconstruction produced a 41.5% margin with a gross contribution margin of $3,248, whereas autografts had a reimbursement rate with a 45% margin with a gross contribution margin of $3,156. CONCLUSIONS: In this study the cost of allograft tissue used in ACL reconstruction was not offset by the savings realized from shorter OR and recovery room times. However, in a hospital-based outpatient setting, reimbursement covered the cost of the allograft, offsetting the additional expense. LEVEL OF EVIDENCE: Level III, retrospective comparative study for economic analysis.
