RESUMO
PURPOSE: To systematically review the literature to compare the efficacy and safety of platelet-rich plasma (PRP), bone marrow aspirate concentrate (BMAC), and hyaluronic acid (HA) injections for the treatment of knee osteoarthritis (OA). METHODS: A systematic review was performed by searching PubMed, the Cochrane Library, and Embase to identify Level I studies that compared the clinical efficacy of at least 2 of the following 3 injection therapies: PRP, BMAC, and HA for knee OA. The search phrase used was knee AND osteoarthritis AND randomized AND ("platelet rich plasma" OR "bone marrow aspirate" OR "hyaluronic acid"). Patients were primarily assessed based on patient-reported outcome scores (PROs) including the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analog scale (VAS) for pain, and Subjective International Knee Documentation Committee (IKDC) score. RESULTS: Twenty-seven studies (all Level I) met inclusion criteria, including 1,042 patients undergoing intra-articular injection(s) with PRP (mean age 57.7 years, mean follow-up 13.5 months), 226 patients with BMAC (mean age 57.0 years, mean follow-up 17.5 months), and 1,128 patients with HA (mean age 59.0 years, mean follow-up 14.4 months). Nonnetwork meta-analyses demonstrated significantly better postinjection WOMAC (P < .001), VAS (P < .01), and Subjective IKDC scores (P < .001) in patients who received PRP compared with patients who received HA. Similarly, network meta-analyses demonstrated significantly better postinjection WOMAC (P < .001), VAS (P = .03), and Subjective IKDC (P < .001) scores in patients who received BMAC compared with patients who received HA. There were no significant differences in postinjection outcome scores when comparing PRP with BMAC. CONCLUSIONS: Patients undergoing treatment for knee OA with PRP or BMAC can be expected to experience improved clinical outcomes when compared with patients who receive HA. LEVEL OF EVIDENCE: Level I, meta-analysis of Level I studies.

BACKGROUND: Multiple studies have compared redislocation rates after stabilization and immobilization for patients experiencing a traumatic, first-time anterior shoulder dislocation (ASD). PURPOSE: To systematically review the literature to compare rates of recurrent instability and subsequent instability surgery in patients undergoing treatment for a first-time ASD with surgical stabilization versus shoulder immobilization. STUDY DESIGN: Systematic review and meta-analysis; Level of evidence, 1. METHODS: A systematic review was performed by searching PubMed, the Cochrane Library, and Embase to identify level 1 randomized studies that compared outcomes of surgical stabilization versus immobilization for treatment of primary ASD. The following search phrase was used: (glenohumeral OR anterior shoulder) AND (conservative OR nonoperative OR nonsurgical OR physiotherapy) AND (Bankart OR repair OR stabilization OR surgical OR surgery OR arthroscopic OR arthroscopy) AND (instability OR dislocation). Patients with soft tissue disruption alone as well as those with additional minor bony lesions (Hill-Sachs, Bankart) were included. Recurrent instability and subsequent instability surgery rates, the Western Ontario Shoulder Instability Index (WOSI), and range of motion were evaluated. RESULTS: A total of 5 studies met inclusion criteria, including 126 patients undergoing surgical stabilization (mean age, 23.6 years; range, 15.0-39.0 years) and 133 patients undergoing treatment with sling immobilization only (mean age, 23.1 years; range, 15.0-31.0 years). Mean follow-up was 59.7 months. Overall, 6.3% of operative patients experienced recurrent instability at latest follow-up compared with 46.6% of nonoperative patients (P < .00001). Similarly, 4.0% of operative patients underwent a subsequent instability surgery compared with 30.8% of nonoperative patients (P < .00001). These same trends were demonstrated when data were isolated to nonoperative patients immobilized in internal rotation. When comparing the operative and nonoperative groups at latest follow-up, 1 study found significantly improved WOSI scores among operative patients (P = .035) and 1 study found significantly improved abducted external rotation in nonoperative patients (P = .02). CONCLUSION: Patients, particularly active men in their 20s and 30s, undergoing treatment for a first-time ASD with a surgical stabilization procedure can be expected to experience significantly lower rates of recurrent instability and a significantly decreased need for a future stabilization procedure when compared with patients treated nonoperatively.

Background: Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) is an advanced imaging technique that is purported to quantify cartilage damage in acute and chronic joint disease and predict periacetabular osteotomy (PAO) outcomes. There is a paucity of literature relating dGEMRIC values to arthroscopic findings before PAO and postoperative outcomes after PAO. Purpose: To assess the utility and validity of dGEMRIC as a preoperative and prognostic assessment tool of cartilage status and integrity as it relates to intraoperative findings and midterm postoperative outcomes after PAO. Study Design: Case series; Level of evidence, 4. Methods: We analyzed a cohort of 58 patients (70 hips) with a median age of 30.1 years (range, 15-50) with hip dysplasia who underwent hip arthroscopy, followed by a PAO with preoperative dGEMRIC. The primary outcome measures were intraoperative assessment and correlation with cartilage damage (presence of cartilage flap, Outerbridge grade of the acetabulum and femoral head). Secondary outcome measures were postoperative patient-reported outcome (PRO) scores, including the International Hip Outcome Tool and Non-arthritic Hip Score. Correlation analyses were performed to determine the relationship between dGEMRIC values and (1) PROs and (2) intraoperative assessment of cartilage damage. Results: There were significant negative linear relationships between dGEMRIC values and the primary outcome measures: presence of a cartilage flap (coronal, P = .004; sagittal, P < .001), Outerbridge grade of acetabular articular cartilage lesion (coronal, P = .002; sagittal, P = .003), and Outerbridge grade of femoral head articular cartilage lesion (coronal, P = .001; sagittal, P < .001). Despite significant overall improvement in all patients, there was no significant correlation between preoperative dGEMRIC values and improvement in PROs from presurgery to latest postoperative follow-up (median, 2.2 years; range, 1.0-5.0 years). Conclusion: Although dGEMRIC values (sagittal and coronal) were significant predictors of the intraoperative presence of cartilage flaps and overall cartilage integrity, they were not associated with midterm outcomes after PAO.
RESUMO
PURPOSE: To systematically review the literature to compare the efficacy of platelet-rich plasma (PRP) and hyaluronic acid (HA) injections for the treatment of hip osteoarthritis (OA). METHODS: A systematic review was performed by searching PubMed, the Cochrane Library, and Embase to identify randomized controlled trials that compared the clinical efficacy of PRP and HA injections for hip OA. The search phrase used was hip, osteoarthritis, platelet-rich plasma, hyaluronic acid, randomized. Patients were assessed based on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the Visual Analog Scale (VAS) for pain, and the Harris Hip Score (HHS). Subanalyses were performed for any outcome score in which ≥3 studies reported results. RESULTS: Six studies (5 level I, 1 level II) met inclusion criteria, including 211 patients undergoing intra-articular injection with PRP (mean age 60.0 years, mean follow-up 12.2 months) and 197 patients with HA (mean age 62.3 years, mean follow-up 11.9 months). No significant differences were found in the weighted improvement of any outcome score (WOMAC, VAS, or HHS) from preinjection to postinjection between groups. When excluding a study with the highest risk of bias to eliminate heterogeneity, pooled subanalysis demonstrated no significant differences in WOMAC subscores between PRP and HA groups. Similarly, in a pooled subanalysis that isolated patients treated with leukocyte-poor PRP, no significant differences in WOMAC subscores were found between PRP and HA groups. CONCLUSION: Patients undergoing treatment for hip OA with either PRP or HA injections can expect to experience similarly beneficial short-term clinical outcomes. LEVEL OF EVIDENCE: II, systematic review of level I and II studies.

PURPOSE: The purpose of this study was to introduce a native labral variant, the everted acetabular labrum, and to describe the patho-anatomy, magnetic resonance imaging and magnetic resonance arthrogram (MRI/MRA) characteristics and the arthroscopic findings in this condition. METHODS: All primary hip arthroscopy procedures performed by the senior author between June 2013 and January 2020 were reviewed retrospectively. An everted acetabular labrum was identified as a segment of labrum that lacked apposition to the femoral head with the hip off traction. All everted labra were treated with labral advancement and repair with or without augmentation or reconstruction. The labrum-to-femoral head distance was measured in 3T MRI/MRA at the 1-2 o'clock position. A random selection of 38 hips without an everted labrum served as controls to compare radiographic parameters. RESULTS: A total of 68 hips were identified as having an everted labrum during the study period (mean age, 29.1 years), and 55 hips had advanced imaging available for review. MRI/MRA scans revealed the everted labrum to have a triangular shape in 17 hips (31%) and a blunted/round shape in 38 hips (69%), which differed significantly from controls (triangular 25/38 [66%], blunted 13/38 [34%], P < 0.001). The average labrum-to-femoral head distance was 1.4 mm for everted labra versus 0.0 mm for controls (P < 0.0001) and the mean labral lengths and widths were significantly shorter than those of controls (both P < 0.01). Of the hips, 8 underwent labral reconstruction or augmentation, and 61 underwent labral advancement/repair. CONCLUSION: The everted acetabular labrum is a native variant that is identifiable during hip arthroscopy by assessing the labral seal off traction. Preoperative MRI/MRA findings can be highly predictive of an everted labrum. Surgical treatment includes labral advancement and repair or reconstruction to restore contact between the labrum and the femoral head. LEVEL OF EVIDENCE: III, retrospective comparative study.

BACKGROUND: Freestyle skiers must optimize their aerial performance by maintaining the strength and coordination to propel themselves in the air and adapt to landings and take-offs on uneven surfaces. The purpose of this study was to investigate the differences in areal bone mineral density (aBMD) and body composition in freestyle skiers and non-freestyle skiing controls. We hypothesized that the unique demands and summation of forces experienced by freestyle athletes would manifest as greater femoral neck aBMD, lower percent body fat, and lower Body Mass Index (BMI) than non-freestyle skiing controls. This is a retrospective cohort study. METHODS: Eighteen freestyle skiers (14 M 4 F, [27.56±5.22 years]) and 15 controls (7 M 8 F, [26.93±3.54 years]) were measured with dual energy X-ray absorptiometry (DXA) to determine total body composition, hip and lumbar spine aBMD, and bone mineral composition (BMC). Height and weight were measured with an in-office stadiometer and scale. Questionnaires were used to determine physical activity and pertinent medical history. Between-group variations were analyzed with an analysis of variance (ANOVA) and stratified by sex. RESULTS: Percent body fat, hip and lumbar spine aBMD, BMC, and area were all similar between freeski and non-freeski athletes (P<0.05 for all). BMI was significantly lower in male freeski athletes (23.97 kg/m2, 95% CI: 22.75-25.18) compared to non-freestyle skiing controls (26.64 kg/m2, 95% CI: 24.43-28.86) (P=0.03). CONCLUSIONS: Freestyle skiers have a lower BMI than non-freestyle skiers. All skiers in this study have similar percent body fat, aBMD, and BMC. This pilot study supports that there are unique musculoskeletal adaptations based on type of skiing. Skiers endure a variety of intense physical forces yet remain understudied despite high orthopedic injury rates. This study serves to broaden the current sports health literature and explore the physical demands and subsequent physiology of freestyle skiers.

PURPOSE: The purpose of this systematic review is to evaluate the current literature in an effort to investigate sleep quality and disturbances and the association with clinical outcomes of patients undergoing shoulder surgery. METHODS: A systematic review of the PubMed, Embase, and Cochrane Library databases was performed according to PRISMA guidelines. All English-language literature reporting clinical outcomes and sleep quality and disturbance after shoulder surgery was reviewed by 2 independent reviewers. Outcomes assessed included patient-reported outcomes (PROs) and sleep quality. Specific PROs included the Pittsburgh Sleep Quality Index (PSQI), Visual Analog Scale (VAS) for pain, Simple Shoulder Test (SST), University of California Los Angeles (UCLA) Shoulder Rating Scale, and American Shoulder and Elbow Surgeons Score (ASES). Study methodology was assessed using the Modified Coleman Methodology Score. Descriptive statistics are presented. RESULTS: Sixteen studies (11 level IV, 2 level III, 3 level II) with a total of 2748 shoulders were included (age, 12-91 years; follow-up, 0.25-132 months). In total, 2198 shoulders underwent arthroscopic rotator cuff repair (RCR), 131 shoulders underwent arthroscopic capsular release, 372 shoulders underwent total shoulder arthroplasty (TSA), 18 shoulders underwent comprehensive arthroscopic management, and 29 shoulders underwent sternoclavicular joint procedures. All shoulder surgeries improved self-reported sleep and PROs from before to after surgery. In RCR patients, PSQI scores were significantly associated with VAS scores, SST scores (r = 0.453, r = -0.490, P < .05, respectively), but not significantly associated with UCLA Shoulder rating scale or the ASES scores (r = 0.04, r = 0.001, P > .05, respectively). In TSA patients, PSQI scores were significantly associated with ASES scores (r = -0.08, P < .05). All 4 RCR studies and 1 TSA study using PSQI found significant improvements in mean PSQI scores within 6 to 24 months (P < .05). CONCLUSIONS: Surgical intervention for rotator cuff tear and glenohumeral osteoarthritis significantly improves self-reported sleep in patients with shoulder pain. However, there remains a dearth of available studies assessing the effects of surgical intervention for adhesive capsulitis, sternoclavicular joint instability, and sternoclavicular osteoarthritis on sleep. Future studies should use sleep-specific PROs and quantitative measures of sleep to further elucidate the relationship between sleep and the effect of shoulder surgery. LEVEL OF EVIDENCE: Level IV, systematic review of Level II-IV studies.

PURPOSE: To evaluate the quality and content of internet-based information available for some of the most common orthopaedic sports medicine terms. METHODS: A search of the PubMed, Embase, and Cochrane databases following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines was performed. All English-language literature published from 2010 to 2020 discussing information quality pertaining to orthopaedic sports medicine terms was included. Outcomes included the search engines used, number and type of websites evaluated, platform, and quality scoring metrics. Descriptive statistics are presented. RESULTS: This review includes 21 studies. Of these, 3 evaluated both the upper and lower extremity. Twelve focused on either the upper or lower extremity, most commonly rotator cuff tears (3 of 12) and/or anterior cruciate ligament pathologies (7 of 12). The most common engines were Google (18 of 21), Bing (16 of 21), Yahoo (16 of 21), YouTube (3 of 21), Ask (3 of 21), and AOL (2 of 21). The average number of media files assessed per study was 87 ± 55. Website quality was assessed with DISCERN (7 of 21), Flesch-Kincaid (9 of 21), Health on the Net (7 of 21), and/or Journal of the American Medical Association Benchmark (7 of 21) scores. YouTube was evaluated with Journal of the American Medical Association Benchmark scores (1.74 ± 1.00). Image quality was reported in 2 studies and varied with search terminology. CONCLUSIONS: The results of this systematic review suggest that physicians should improve the quality of online information and encourage patients to access credible sources when conducting their own research. CLINICAL RELEVANCE: Doctors can and should play an active role in closing the gap between the level of health literacy of their patients and that of most common online resources.
RESUMO
BACKGROUND: The purpose of this study was to describe the clinical outcomes following bilateral total shoulder arthroplasty (TSA). METHODS: A systematic search of the PubMed, Embase, and Cochrane Library databases following PRISMA guidelines was performed. English-language literature published from 2010 to 2018 analyzing bilateral TSA (anatomic and/or reverse) with a minimum one-year follow-up was reviewed by two independent reviewers. Study quality was evaluated with the Modified Coleman Methodology Score and the methodological index for non-randomized studies score. RESULTS: Eleven studies (1 Level II, 3 Level III, 7 Level IV) with 292 patients were included. Two studies reported on bilateral anatomic TSA (n = 54), six reported on bilateral reverse TSA (RTSA; n = 168), two reported on anatomic TSA with contralateral RTSA (TSA/RTSA; n = 31), and one compared bilateral anatomic TSA (n = 26) and bilateral RTSA (n = 13). Among studies, mean revision rate ranged from 0% to 10.53% and mean complication rate ranged from 4.9% to 31.3%. At final follow-up, patients experienced significant overall improvements in range of motion and patient-reported outcome score measurements. However, bilateral anatomic TSA resulted in greater improvements in external rotation compared to bilateral RTSA. Overall patient satisfaction was 91.0%. CONCLUSION: The available data indicate that bilateral TSA allows for functional and pain improvements and result in high patient satisfaction. LEVEL OF EVIDENCE: IV.
RESUMO
BACKGROUND: The impact of preoperative opioid use on outcomes after shoulder surgery is unknown. PURPOSE/HYPOTHESIS: To examine the role of preoperative opioid use on outcomes in patients after shoulder surgery. We hypothesized that preoperative opioid use in shoulder surgery will result in increased postoperative pain and functional deficits when compared with nonuse. STUDY DESIGN: Systematic review; Level of evidence, 3. METHODS: A systematic review was performed using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Included were all English-language studies comparing clinical outcomes of shoulder surgery in patients who used opioids preoperatively (opioid group) as well as patients who did not (nonopioid group) with a minimum follow-up of 1 year. Outcomes included range of motion, American Shoulder and Elbow Surgeons score, Constant-Murley score, and visual analog scale for pain. Study quality was evaluated with the Modified Coleman Methodology Score and the MINORS score (Methodological Index for Non-randomized Studies). RESULTS: Included were 5 studies (level 2, n = 1; level 3, n = 4): Two studies were on total shoulder arthroplasty, 2 on reverse total shoulder arthroplasty, 1 on both, and 1 on arthroscopic rotator cuff repair. There were 827 patients overall: 290 in the opioid group (age, 63.2 ± 4.0 years [mean ± SD]; follow-up, 38.9 ± 7.5 months) and 537 in the nonopioid group (age, 66.0 ± 4.7 years; follow-up, 39.5 ± 8.1 months). The opioid group demonstrated significantly worse pre- and postoperative visual analog scale and Constant-Murley score pain scores as compared with the nonopioid group. Mean American Shoulder and Elbow Surgeons scores were significantly lower in the opioid group at pre- and postoperative time points as compared with the nonopioid group (P < .05 for all). However, both groups experienced similar improvement in outcomes pre- to postoperatively. One study showed that the opioid group consumed significantly more opioids postoperatively than the nonopioid group and for a longer duration (P < .05). The overall mean Modified Coleman Methodology Score and MINORS score were 64.2 ± 14 and 15.8 ± 1.0, respectively. CONCLUSION: Opioid use prior to various shoulder surgical procedures negatively affected postoperative pain and functionality. Although the opioid group showed significantly worse scores postoperatively, the groups experienced similar improvements.
RESUMO
BACKGROUND: Hyaluronic acid (HA) and leukocyte-poor platelet-rich plasma (LP-PRP) are 2 nonoperative treatment options that have been studied in patients with hip osteoarthritis (OA). PURPOSE: To compare the efficacy of intra-articular injections of low-molecular weight (LMW) HA and LP-PRP in patients with hip OA. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: A total of 34 patients (36 hips) presenting with signs of hip OA were randomized to receive 3 blinded, weekly intra-articular injections of either LP-PRP or LMW-HA. Patients were prospectively evaluated before injections and at 6 weeks and then at 3, 6, 12, and 24 months. The primary outcome, conversion to total hip arthroplasty (THA) or a hip resurfacing procedure, was analyzed along with secondary outcomes including the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and hip range of motion. RESULTS: The final analysis included 33 hips (mean Kellgren-Lawrence grade, 2.73) (LMW-HA: n = 14; LP-PRP: n = 19) in 31 patients (18 male; mean age, 53.8 years). Significantly more patients converted to THA or a hip resurfacing procedure in the LMW-HA group (7/14; 50.0%) (mean, 1.3 years after first injection) than the LP-PRP group (3/19; 15.8%) (mean, 0.73 years after first injection) (P = .035). There was no significant improvement or decline in any outcome scores within the LMW-HA group from before injections to 6 weeks or 3, 6, and 12 months. For the LP-PRP group, WOMAC overall (P = .032), joint (P = .030), and function scores (P = .025) significantly improved from before injections to 6 weeks, and WOMAC joint scores significantly improved from before injections to 6 months (P = .036). When comparing the difference between groups in internal rotation at 90° of hip flexion from before injections to 6 months, the LP-PRP group demonstrated a mean 5.0° improvement, while the LMW-HA group showed a mean 1.5° decrease (P = .028). CONCLUSION: Intra-articular hip injections of LP-PRP in patients with hip OA resulted in an improvement in WOMAC scores and hip internal rotation at 6 months and delayed the need for THA or a hip resurfacing procedure compared with treatment with LMW-HA. A longer follow-up is necessary to further compare the effects of LP-PRP and LMW-HA injections in patients with hip OA. REGISTRATION: NCT01920152 (ClinicalTrials.gov identifier).
RESUMO
BACKGROUND: Medial ulnar collateral ligament (UCL) injuries are common among baseball players. There is sparse literature on long-term results after nonoperative treatment of UCL injuries in professional baseball players. PURPOSE: The primary purpose was to assess long-term follow-up on reinjury rates, performance metrics, rate of return to the same level of play or higher (RTP), and ability to advance to the next level of play in professional baseball players after nonoperative treatment of incomplete UCL injuries. The secondary aim was to perform a matched-pair comparison between pitchers treated nonoperatively and a control group without a history of UCL injuries. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Twenty-eight professional baseball players (18 pitchers, 10 position players) treated nonoperatively were identified from a previous retrospective review of a single professional baseball organization between 2006 and 2011. UCL reinjury rates and player performance metrics were evaluated at long-term (minimum, 9 years) follow-up. Rates of RTP were calculated. A matched-pair comparison was made between the pitchers treated nonoperatively and pitchers without a history of UCL injuries. RESULTS: Overall, 27 players (17 pitchers, 10 position players) were available for long-term follow-up at a mean follow-up of 12 years (SD, 2 years). The overall rate of RTP was 85% (23/27), with the rate of RTP being 82% (14/17) in pitchers and 90% (9/10) in position players. Of the 23 players who did RTP, 18 (78%) reached a higher level of play and 5 (21.7%) stayed at the same level. Of the 9 position players who did RTP, the median number of seasons played after injury was 4.5 (interquartile range, 3.3). Of the 14 pitchers who did RTP, the mean number of seasons played after injury was 5.8 (SD, 3.8). In the matched-pair analysis, no significant differences were observed in any performance metrics (P > .05). The overall reinjury rate was 11.1% (3/27), with no players requiring UCL reconstruction. CONCLUSION: There was a high rate of RTP for professional baseball players treated nonoperatively for incomplete UCL injuries. Compared with a matched cohort with no history of UCL injury, professional baseball pitchers treated nonoperatively had similar performance metrics. Reinjury rates were low, and no player had reinjury requiring UCL reconstruction. Nonoperative treatment of incomplete UCL injuries in professional baseball players, specifically pitchers, is a viable treatment option in the long term.

BACKGROUND: A paucity of literature exists on the outcomes after Latarjet for anterior shoulder instability in patients with seizure disorders (SDs). The purpose of this study was to determine the effectiveness of the Latarjet procedure for anterior shoulder instability in patients with SDs. METHODS: A retrospective review of patients undergoing Latarjet from 2013 to 2017 for anterior shoulder instability with minimum 2 years of clinical follow-up was performed. Patients were divided into two groups: patients diagnosed with SD, and patients without a history of seizure (control). Demographics, indications, SD details, and postoperative outcomes were collected. The incidence of complications, recurrent instability, revision surgery, and repeat seizure(s) were also examined. RESULTS: A total of 53 patients were identified, including 10 shoulders in 9 patients with an SD (88.9% male; mean age, 29.2 years [range, 20-37]), and 44 shoulders in 44 non-SD patients (86.4% male; mean age, 30.3 years [range, 18-52]). The mean follow-up time was 3.4 (range, 2.2-4.8) and 3.8 (range, 2.1-5.6) years in the SD and control group, respectively. During the follow-up period, 4 of 9 (44.4%) patients with an SD (50% shoulders) had a recurrent seizure postoperatively. Of those 4 patients, three sustained a recurrent dislocation of the operative shoulder(s) resulting from a postoperative seizure, including one who dislocated bilateral shoulders from a single seizure event after bilateral Latarjet procedures. There was no recurrent instability in patients who did not sustain a seizure in the postoperative period. Having a seizure in the postoperative period significantly increased the risk of recurrent dislocation (OR = 39.9, P = 0.04). CONCLUSIONS: Latarjet is a successful operation for recurrent anterior shoulder instability in patients without an SD. While it can still be successful in patients with SD, adequate control of seizures postoperatively is paramount to prevent recurrent instability episodes. Patients with an SD can be advised that if their seizures can remain controlled, they have a high likelihood of clinical success equal to that of patients without an SD.
RESUMO
PURPOSE: To systematically review the literature to evaluate the biomechanical properties of the suture anchor (SA) versus transosseous tunnel (TO) techniques for quadriceps tendon (QT) repair. METHODS: A systematic review was performed by searching PubMed, the Cochrane Library, and Embase using PRISMA guidelines to identify studies that evaluated the biomechanical properties of SA and TO techniques for repair of a ruptured QT. The search phrase used was "quadriceps tendon repair biomechanics". Evaluated properties included ultimate load to failure (N), displacement (mm), stiffness (N/mm), and mode of failure. RESULTS: Five studies met inclusion criteria, including a total of 72 specimens undergoing QT repair via the SA technique and 42 via the TO technique. Three of 4 studies found QTs repaired with SA to have significantly less elongation upon initial cyclic loading when compared to QTs repaired with the TO technique (P < .05). Three of 5 studies found QTs repaired with SA to have significantly less elongation upon final cyclic loading when compared to QTs repaired with the TO technique (P < .05). The pooled analysis from 4 studies reporting on initial displacement showed a statistically significant difference in favor of the SA group compared to the TO group (P = .03). The pooled analysis from studies reporting on secondary displacement and ultimate load to failure showed no significant difference between the SA and TO groups (P > .05). The most common mode of failure in both groups was suture slippage. CONCLUSION: On the basis of the included cadaveric studies, QTs repaired via the SA technique have less initial displacement upon cyclic testing when compared to QTs repaired via the TO technique. However, final displacement and ultimate load to failure outcomes did not reveal differences between the two fixation strategies. Knot slippage remains a common failure method for both strategies.
RESUMO
BACKGROUND: Platelet-rich plasma (PRP) and hyaluronic acid (HA) are 2 nonoperative treatment options for knee osteoarthritis (OA) that are supposed to provide symptomatic relief and help delay surgical intervention. PURPOSE: To systematically review the literature to compare the efficacy and safety of PRP and HA injections for the treatment of knee OA. STUDY DESIGN: Meta-analysis of level 1 studies. METHODS: A systematic review was performed by searching PubMed, the Cochrane Library, and Embase to identify level 1 studies that compared the clinical efficacy of PRP and HA injections for knee OA. The search phrase used was platelet-rich plasma hyaluronic acid knee osteoarthritis randomized. Patients were assessed via the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analog scale (VAS) for pain, and Subjective International Knee Documentation Committee (IKDC) scale. A subanalysis was also performed to isolate results from patients who received leukocyte-poor and leukocyte-rich PRP. RESULTS: A total of 18 studies (all level 1) met inclusion criteria, including 811 patients undergoing intra-articular injection with PRP (mean age, 57.6 years) and 797 patients with HA (mean age, 59.3 years). The mean follow-up was 11.1 months for both groups. Mean improvement was significantly higher in the PRP group (44.7%) than the HA group (12.6%) for WOMAC total scores (P < .01). Of 11 studies based on the VAS, 6 reported PRP patients to have significantly less pain at latest follow-up when compared with HA patients (P < .05). Of 6 studies based on the Subjective IKDC outcome score, 3 reported PRP patients to have significantly better scores at latest follow-up when compared with HA patients (P < .05). Finally, leukocyte-poor PRP was associated with significantly better Subjective IKDC scores versus leukocyte-rich PRP (P < .05). CONCLUSION: Patients undergoing treatment for knee OA with PRP can be expected to experience improved clinical outcomes when compared with HA. Additionally, leukocyte-poor PRP may be a superior line of treatment for knee OA over leukocyte-rich PRP, although further studies are needed that directly compare leukocyte content in PRP injections for treatment of knee OA.

BACKGROUND: Biceps tenodesis and tenotomy are 2 surgical treatment options for relief of long head of the biceps tendon (LHBT) pathology and superior labrum anterior-to-posterior (SLAP) tears. The purpose of this systematic review was to compare the clinical outcomes and complications of biceps tenodesis and tenotomy for the treatment of LHBT or SLAP pathology during shoulder arthroscopy. METHODS: We performed a systematic review by searching PubMed, the Cochrane Library, and Embase to identify level I randomized controlled trials that compared the clinical outcomes of biceps tenodesis vs. tenotomy. The search phrase used was as follows: biceps tenodesis tenotomy randomized. Patients were assessed based on the American Shoulder and Elbow Surgeons score, visual analog scale score for pain, and Constant-Murley score, as well as postoperative range of motion, strength, and cosmetic deformity. RESULTS: Five studies (all level I) met the inclusion criteria, including 236 patients undergoing biceps tenodesis (mean age, 60.3 years) and 232 patients undergoing biceps tenotomy (mean age, 59.7 years). The mean follow-up period was 23.0 months. Overall, 6.8% of tenodesis patients experienced cosmetic deformity at latest follow-up compared with 23.3% of tenotomy patients (P < .001). No differences in Constant-Murley, visual analog scale, or American Shoulder and Elbow Surgeons scores were found between groups in any study, and of all the studies evaluating strength and range of motion at latest follow-up, only 1 found a significant difference between groups, in which tenodesis patients demonstrated significantly increased forearm supination strength (P = .02). One study found tenodesis patients to experience significantly more biceps cramping at 6-month follow-up compared with tenotomy patients (P = .043), although no differences in complication rates at latest follow-up were found in any study. CONCLUSION: Patients undergoing treatment for LHBT or SLAP pathology with either biceps tenodesis or tenotomy can be expected to experience similar improvements in patient-reported and functional outcomes. There is an increased rate of cosmetic deformity in patients undergoing biceps tenotomy compared with tenodesis.

PURPOSE: To perform an updated systematic review of the anatomy, biomechanics, function of the anterolateral ligament (ALL), and the clinical outcomes of anterolateral ligament reconstruction (ALLR) when performed in conjunction with anterior cruciate ligament reconstruction (ACLR). METHODS: A systematic search of the literature was performed by searching PubMed, the Cochrane Library, and Embase with the search phrase anterolateral ligament for articles published from February 2017 to May 2020. Inclusion criteria included studies that evaluated the anatomy, function, or biomechanics of the ALL; surgical technique articles on ALLR; clinical articles reporting outcomes of ALLR; studies published in English; and full-text articles. Exclusion criteria included studies published before February 2017. A subjective synthesis was performed, in which ranges were reported, and individual study data were presented in forest plots. RESULTS: Overall, 40 articles were included in this systematic review, with 11 articles describing ALL anatomy, 14 articles analyzing ALL function and biomechanics, 7 articles discussing the surgical technique of combined ACLR and ALLR (ACLR/ALLR), and 8 articles describing the clinical outcomes of ACLR/ALLR. The addition of ALLR in combination with ACLR (ACLR+) results in lower graft failure rates for ACLR/ALLR (0.0%-15.7%) when compared with isolated ACLR (I-ACLR) patients (7.4%-21.7%). Three of 5 studies using the Subjective International Knee Documentation Committee score, 2 of 5 studies using the Lysholm score, and 1 of 2 studies using the Tegner score reported significantly better scores at latest follow-up among ACLR+ patients compared with I-ACLR (P < .05). CONCLUSIONS: The ALL acts as a secondary stabilizer to the anterior cruciate ligament and helps resist internal knee rotation and anterior tibial translation. Based on the current literature, combined ACLR with ALLR may result in lower graft failure rates and improved patient-reported outcomes when compared with I-ACLR in patients with specific indications, although several studies have shown equivalent outcomes between these 2 cohorts. CLINICAL RELEVANCE: The contents of this review provide great insight for orthopaedic surgeons who are performing ACLR and considering additional procedures to increase overall knee stability and decrease likeliness for re-rupture. The postoperative functional and clinical outcomes shown in patients undergoing ACLR+ compared with I-ACLR should be given proper consideration when evaluating available treatment courses.

PURPOSE: To systematically review the literature to compare the efficacy and safety of tranexamic acid (TXA) as a means to minimize hemarthrosis-related complications after arthroscopic procedures of the knee, hip, and shoulder. METHODS: A systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed by searching PubMed, Cochrane Library, and Embase databases to locate randomized controlled trials comparing the clinical outcomes and postoperative complications of patients undergoing arthroscopy with and without TXA. Search terms used were "tranexamic acid," "arthroscopy," "knee," "hip," and "shoulder." Patients were evaluated based on early (<6 weeks) postoperative signs of hemarthrosis using the Coupens and Yates classification, postoperative complications (myocardial infarction, stroke, venous thromboembolism events), range of motion (ROM), and patient-reported outcome scores (Visual analog scale, Subjective International Knee Documentation Committee, Lysholm, and Tegner activity scores). RESULTS: Five studies (2 level I and 3 level II) met inclusion criteria, including a total of 299 patients undergoing arthroscopy with TXA and 299 patients without TXA. The average follow-up duration for all patients was 43.9 days. Procedures performed were partial meniscectomy, anterior cruciate ligament reconstruction, and rotator cuff repair. No studies evaluating TXA use in hip arthroscopy were identified. Coupens-Yates hemarthrosis grades significantly improved in the TXA groups across all studies. Three studies found TXA patients to experience significantly less postoperative pain at latest follow-up, 1 study found TXA patients to have significantly better postoperative Lysholm scores, and 1 study found TXA patients to have significantly more ROM at latest follow-up compared with non-TXA patients (P < .05). CONCLUSION: Patients undergoing arthroscopy, particularly arthroscopic meniscectomy, arthroscopic-assisted anterior cruciate ligament reconstruction, and arthroscopic rotator cuff repair, with TXA can be expected to experience improved outcomes and less hemarthrosis-related complications in the early postoperative period compared with non-TXA patients. LEVEL OF EVIDENCE: II, systematic review of level I and II studies.

PURPOSE: To determine whether range of motion (ROM) varies with the location and extent of labral tear seen in patients undergoing arthroscopic anterior shoulder stabilization. METHODS: Consecutive patients undergoing arthroscopic anterior shoulder stabilization who were enrolled in the Multicenter Orthopaedic Outcomes Network Shoulder Instability database underwent a preoperative physical examination and intraoperative examination under anesthesia in which ROM was recorded. Intraoperatively, the location and extent of the labral tear was recorded using conventional clock-face coordinates. Patients were grouped by combinations of quadrants involved in the labral tear (G1-G7): G1 = anterior only, G2 = anterior + inferior, G3 = anterior + inferior + posterior, G4 = all quadrants, G5 = superior + anterior, G6 = superior + anterior + inferior, and G7 = posterior + superior + anterior. Statistical analyses were performed with the Kruskal-Wallis rank-sum test. When P < .05, a post-hoc Dunn's test was performed. For categorical variables, the χ2 test was performed. We performed a series of bivariate negative binomial regression models testing pairwise combinations of ROM parameters predicting the count of labral tear locations (possible: 0-5) within each quadrant. RESULTS: A total of 467 patients were included, with 13 (2.8%) in G1, 221 (47.3%) in G2, 40 (8.6%) in G3, 51 (10.9%) in G4, 18 (3.9%) in G5, 121 (25.9%) in G6, and 3 (0.6%) in G7. Multiple statistically significant differences were noted in ROM, specifically active internal rotation at side (IRS) (P = .005), active abduction (P = .02), passive IRS (P = .02), and passive external rotation in abduction (P = .0007). Regression modeling revealed a positive correlation between passive abduction and predicted count of labral tear locations in the superior quadrant and between passive IRS and predicted count of labral tear location in the inferior quadrant. CONCLUSIONS: In patients undergoing arthroscopic shoulder stabilization for anterior instability, ROM varies with location and extent of labral tear. However, the clinical relevance of such small ROM differences remains undetermined. LEVEL OF EVIDENCE: II, prospective comparative study.
RESUMO
PURPOSE: The purpose of this systematic review was to examine the effect that sex has on recurrence of anterior shoulder instability following primary arthroscopic anterior shoulder stabilization. METHODS: A systematic review using PRISMA guidelines was performed by searching PubMed, Embase and Cochrane Library databases to identify studies reporting recurrence rates following arthroscopic anterior shoulder stabilization with a minimum follow-up period of 2 years. Patient demographics as well as preoperative, intraoperative and postoperative findings, including patient-reported outcomes and recurrence rates, were analyzed by 2 independent reviewers. Recurrence was defined as an episode of dislocation, subluxation or instability following primary arthroscopic anterior shoulder stabilization. Study methodological quality was evaluated with the Modified Coleman Methodology Score (MCMS). Risk bias was evaluated using the Methodological Index for Non-randomized Studies (MINORS score). Descriptive statistics are presented. RESULTS: Ten studies (1 Level I, 1 Level II, 5 Level III, and 3 Level IV), including a total of 7,102 patients with primary traumatic and/or recurrent traumatic shoulder instability without previous procedures who underwent primary arthroscopic anterior shoulder stabilization, were included (mean follow-up, 34.6 months; mean age, 25.4 years). There was a total of 5,097 males (71.8%) and 2,005 females (28.2%). There was a higher recurrence rate in males (6%-37%) compared to females (0-32%). Clinical outcomes were inconsistently reported, so no quantitative analysis of clinical outcomes or return-to-sport between sexes was possible. The average MCMS of all 10 studies was 76.8 ± 8.0, indicating good methodology. CONCLUSIONS: Males may have higher recurrence rates than females following primary arthroscopic anterior shoulder stabilization; however, the heterogeneity of the included studies precludes any definitive conclusions. LEVEL OF EVIDENCE: IV, Systematic Review of Level I-IV.
