Superior Pain Reduction with Anteromedialization Tibial Tubercle Osteotomy Versus Non-Operative Management for Patellofemoral Osteoarthritis.

PURPOSE: The purpose of this study was to compare the clinical outcomes of patients with patellofemoral osteoar-thritis (PFOA) treated non-operatively with those treated operatively with an unloading anteromedialization tibial tubercle osteotomy (TTO). METHODS: A retrospective chart review was performed to identify patients with isolated PFOA who were either managed non-operatively or surgically with a TTO and who had a minimum follow-up of 2 years. Patients were surveyed with the visual analog scale (VAS) for pain, Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR), Anterior Knee Pain scale (Kujala), and Tegner Activity scale. Statistical analysis included two-sample t-testing, one-way ANOVA, and bivariate analysis. RESULTS: The clinical outcomes of 49 non-operatively managed patients (mean age: 52.7 ± 11.3 years; mean follow-up: 1.7 ± 1.0 years) and 35 operatively managed patients (mean age: 31.8 ± 9.4 years; mean follow-up: 3.5 ± 1.7 years) were assessed. The mean VAS improved sig-nificantly in both groups [6.12 to 4.22 (non-operative), p < 0.0001; 6.94 to 2.45 (TTO); p < 0.0001], with operatively treated patients having significantly lower postoperative pain than non-operatively managed patients at the time of final follow-up [2.45 (TTO) vs. 4.22 (non-operative), p < 0.001]. The mean KOOS-JR score was significantly greater in the operative group at time of final follow-up [78.7 ± 11.6 (TTO) vs. 71.7 ± 17.8 (non-operative), p = 0.035]. There was no significant difference in Kujala or Tegner scores between the treatment groups. Additionally, there was no sig-nificant relationship between the number of intra-articular injections, duration of NSAID use, and number of physical therapy sessions on clinical outcomes in the non-operatively treated group (p > 0.05). CONCLUSIONS: An unloading anteromedialization TTO provides significantly better pain relief and restoration of function compared to non-operative management in the treatment of symptomatic PFOA.

Matrix-Induced Autologous Chondrocyte Implantation Versus Autologous Chondrocyte Implantation of the Knee A Retrospective Comparison.

OBJECTIVE: The purpose of this study was to compare the short-term clinical outcomes of matrix-induced autologous chondrocyte implantation (MACI) to those seen following traditional autologous chondrocyte implantation (ACI) in the management of symptomatic cartilage lesions of the knee. METHODS: This was a retrospective cohort study of patients who underwent either ACI or MACI from January 2011 to March 2018. Patients with a minimum postoperative follow-up of 18 months were contacted. Demographic information, intraoperative findings, and patient-reported functional outcomes scores were collected. Comparisons were made between the two cell-based cartilage repair techniques. RESULTS: Fifty-six patients were included in the study (39 ACI, 17 MACI). Visual analog scale (VAS) for pain scores improved significantly in both groups, with MACI patients demonstrating significantly lower postoperative pain scores compared to those treated with ACI. In the ACI group, there was a decrease in the Tegner Activity score compared to the preoperative baseline, while no significant difference was seen between pre- and postoperative activity levels in the MACI group. Patients were generally satisfied with the outcome of their procedures, and there was no significant difference in satisfaction between groups. No patients re-quired additional surgery during the follow-up period. CONCLUSION: Both ACI and MACI demonstrated good short-term postoperative clinical results with improved pain and activity levels compared to the preoperative baseline. Patients treated with the MACI technique demonstrated greater reductions in pain scores compared to ACI, and while ACI resulted in a decrease in levels of postoperative activity, activity levels for MACI remained stable.

High Rate of Patient Satisfaction with Either Telemedicine or Traditional Office-Based Follow-Up Visit After Arthroscopic Shoulder Surgery.

Background: The purpose of this study was to determine if any differences exist in patient satisfaction with office-based visits versus telemedicine visits following arthroscopic shoulder surgery. Methods: Patients undergoing shoulder arthroscopy were prospectively enrolled for 1 year. Patient demographic and clinical data (including complication events) and second postoperative visit satisfaction data were recorded and analyzed for statistical significance. Results: Ninety-six (n = 96) patients met inclusion criteria. Fifty-four patients (56.3%) participated in a traditional in-person office visit, and 42 participated in a video visit (43.8%). No significant differences were found between office and video appointments in terms of overall care satisfaction (9.46 ± 0.9 vs. 9.55 ± 1.0, p = 0.67). Females were significantly less satisfied with their second postoperative visit compared with males (8.3 ± 2.3 vs. 9.3 ± 1.5, p = 0.035). Significantly more females would also have preferred a traditional in person office visit compared with males (91% vs. 67%, p = 0.009). Video appointment patients spent significantly more time with their surgeon than office visit patients (57.64 mean rank vs. 41.39 mean rank, p = 0.003). Discussion: Video visit patients required significantly less time overall for their visit and spent significantly more time with their surgeon, although did not demonstrate differences in satisfaction.

Pain-management protocol aimed at reducing opioids following total knee arthroplasty does not negatively impact patient satisfaction.

BACKGROUND: Prior research has demonstrated that the prescription of opioid medications may be associated with the desire to treat pain in order to achieve favorable patient satisfaction. The purpose of the current study was to investigate the effect of decreased opioid prescribing following total knee arthroplasty (TKA) on survey-administered patient satisfaction scores. METHOD: This study is a retrospective review of prospectively collected survey data for patients who underwent primary elective TKA for the treatment of osteoarthritis (OA) between September 2014 and June 2019. All patients included had completed Hospital Consumer Assessment of Healthcare Providers and Systems (HCAPS) survey information. Patients were stratified into two cohorts based on whether their surgery took place prior to or subsequent to the implementation of an institutional-wide opioid-sparing regimen. RESULTS: Of the 613 patients included, 488 (80%) were in the pre-protocol cohort and 125 (20%) in the post-protocol cohort. Rate of opioid refills (33.6% to 11.2%; p < 0.001) as well as length of stay (LOS, 2.40 ± 1.05 to 2.13 ± 1.13 days; p = 0.014) decreased significantly after protocol change while rate of current smokers increased significantly (4.1% to 10.4%; p = 0.011). No significant difference was observed in "top box" percentages for satisfaction with pain control (Pre: 70.5% vs Post: 72.8%; p = 0.775). CONCLUSIONS: Protocols calling for reduced prescription of opioids following TKA resulted in significantly lower rates of opioid refills, and were associated with significantly shorter LOS, while causing no statistically significant deleterious changes in patient satisfaction, as measured by HCAPS survey. LOE: III. CLINICAL RELEVANCE: This study suggests that HCAPS scores are not negatively impacted by a reduction in postoperative opioid analgesics.

Complications of Single-Incision Versus Dual-Incision Distal Biceps Repair A Systematic Review and Meta-Analysis of Comparative Studies.

PURPOSE: The purpose of this study was to systematically review and analyze the current evidence in the literature to determine the relative complication rates of the singleincision versus dual-incision approach to distal biceps tendon repair. METHODS: The literature search was performed based on the PRISMA guidelines. Cohort studies comparing the single-incision or dual-incision approach to biceps tendon repair alone were included. Clinical outcomes were compared, with all statistical analysis performed using Review Manager Version 5.3. A p-value < 0.05 was considered to be statistically significant. RESULTS: Twelve clinical studies with varying levels of evidence (LOE I: 1, LOE II: 1, LOE III: 10) with 2,429 patients were included. Overall, there was a significantly lower rate of total complications with the dual-incision approach (16.1% vs. 23.1%, p < 0.01) and a lower rate of neurological injuries (9.1% vs. 24.1%, p < 0.01). There was a lower rate of lateral antebrachial cutaneous nerve injuries with the dual-incision approach (5.2% vs. 19.5%, p < 0.01), and superficial radial nerve injuries (2.5% vs. 4.8%, p < 0.01), but there was no significant difference in the rate of posterior interosseous nerve injuries (2.2% vs. 1.2%, p = 0.20). There was a significantly lower rate of heterotopic bone formation with the single-incision approach (1.3% vs. 2.7%, p = 0.01). CONCLUSION: The dual-incision approach decreases the risk of total, overall postoperative complications and sensory nerve injuries following distal biceps repair. However, it has a higher risk of heterotopic bone formation.

Knee Osteotomies Can Be Performed Safely In An Ambulatory Setting.

Purpose: The purpose of this study was to assess the rate of hospital admissions, inpatient conversions, reoperations, and complications associated with tibial tubercle osteotomies (TTO), high tibial osteotomies (HTO), and distal femoral osteotomies (DFO) performed at our ambulatory surgery center compared with our inpatient hospital facility. Methods: A retrospective review of patients receiving a TTO, HTO or DFO at our institution between June 2011 and October 2019 was performed. Inclusion criteria consisted of patients undergoing the aforementioned procedures for malalignment, and a minimum of 90-days follow-up. Revision osteotomies, those undergoing an osteotomy for an acute fracture, and those with rule-out criteria for outpatient surgery (ASA > 3, and body mass index >40) were excluded. Complications, including readmission and reoperation, were compared between the two groups using either the Fisher's exact test and independent samples t-test, where applicable, and a P value of <0.05 was considered to be statistically significant. Results: The study included 531 patients undergoing osteotomies (222 ambulatory surgical center [ASC] and 309 hospital) with no patients lost to follow-up in the 90-day postoperative period. No patients operated on at an ASC required transfer to inpatient setting. There were no differences in complication rates, readmission, or reoperation rates among the two groups (4.1% vs 4.9%; P = .8328; 3.1% vs 4.5%, P = .5026; 3.1% vs 4.5%; P = .5026; respectively). Complications, including surgical site infection and arthrofibrosis were not significantly different in the two cohorts, (1.4% vs. 2.6%, P = .341 and 1.4% vs 1%; P = .698, respectively). Conclusions: Osteotomies about the knee performed in an ambulatory setting were safe, with no difference in readmission, reoperation, or postoperative complications compared to those performed at an inpatient hospital. Additionally, no patient required conversion from an outpatient to an inpatient setting. Level of Evidence: Level III, retrospective comparative study.

Synovial Fluid Cytokine Profile at the Time of Arthroscopy Explains Intermediate-Term Functional Outcomes.

BACKGROUND: The intra-articular immune response after ligamentous, meniscal, or focal chondral knee injuries likely plays a role in intra-articular healing and the onset and progression of posttraumatic osteoarthritis. PURPOSE: To evaluate the association of synovial fluid cytokine concentrations measured at the time of knee arthroscopy with intermediate-term functional outcomes after knee arthroscopy based on the Lysholm score. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: This was a prospective cohort study of patients undergoing arthroscopic knee surgery. Synovial fluid was aspirated from the injured knee immediately before surgical incision, and the concentrations of 10 cytokines were analyzed using immunoassay. Principal component regression was used to create a model to predict patient-reported Lysholm score at a minimum of 5 years postoperatively. Hierarchical clustering was performed to identify groups of patients with similar synovial fluid inflammatory phenotypes. Lysholm scores and cytokine concentrations were compared between clusters. RESULTS: A total of 26 patients (mean age, 40.33 ± 16.40 years) were included in the analysis. The mean duration between surgery and follow-up was 6.69 ± 0.72 years. A model consisting of 2 principal components (PC1, PC2) explained 62.48% of the variance in the cytokine data and 52.03% of the variance in intermediate-term Lysholm score. Hierarchical clustering resulted in 3 patient clusters based on the principal components used in the regression model. Despite no baseline differences in Lysholm score, cluster 3 demonstrated significantly greater intermediate-term Lysholm score compared with cluster 2 (94.33 vs 76.09, respectively; 95% CI, 5.96-30.52; P = .006) and cluster 1 (94.33 vs 52.33, respectively; 95% CI, 24.09-59.91; P = .003). Cluster 3, when compared with the overall means, was characterized by greater PC1 value (1.01 vs 0.00, respectively; P = .030) and greater PC2 value (0.86 vs 0.00, respectively; P = .002). CONCLUSION: The concentrations of select synovial fluid cytokines assessed at the time of knee arthroscopy can be used to explain more than half of the variance in intermediate-term functional outcomes.

High Tibial Osteotomies for the Treatment of Osteoarthritis of the Knee.

¼: A high tibial osteotomy (HTO) is a joint-preserving procedure that can be used to treat symptomatic unicompartmental cartilage disorders in the presence of limb malalignment. ¼: Appropriate patient selection and careful preoperative planning are vital for optimizing outcomes. ¼: Based on past literature, correction of varus malalignment to 3° to 8° of valgus appears to lead to favorable results. Recently, there has been growing awareness that it is important to consider soft-tissue laxity during preoperative planning. ¼: Although there has been a recent trend toward performing opening-wedge rather than closing-wedge or dome HTOs for unicompartmental osteoarthritis, current data suggest that all 3 are acceptable techniques with varying complication profiles. ¼: Based on current evidence, an HTO provides pain relief, functional improvement, and a high rate of return to sport, with reported survivorship ranging from 74.7% to 97.6% and 66.0% to 90.4% at 10 and 15 years, respectively.

Reducing Postoperative Opioid-prescribing Following Posterior Lumbar Fusion Does Not Significantly Change Patient Satisfaction.

STUDY DESIGN: Retrospective comparative; LOE-3. OBJECTIVE: The purpose of this study was to investigate what effect, if any, an institutional opioid reduction prescribing policy following one- or two-level lumbar fusion has on Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey results. SUMMARY OF BACKGROUND DATA: Previous research has demonstrated that high levels of opioid-prescribing may be related, in part, to a desire to produce superior patient satisfaction. METHODS: A retrospective review of prospectively collected data was conducted on patients who underwent one- or two-level lumbar fusions L3-S1 between October 2014 and October 2019 at a single institution. Patients with complete survey information were included in the analysis. Patients with a history of trauma, fracture, spinal deformity, fusions more than two levels, or prior lumbar fusion surgery L3-S1 were excluded. Cohorts were based on date of surgery relative to implementation of an institutional opioid reduction policy, which commenced in October 1, 2018. To better compare groups, opioid prescriptions were converted into milligram morphine equivalents (MME). RESULTS: A total of 330 patients met inclusion criteria: 259 pre-protocol, 71 post-protocol. There were 256 one-level fusions and 74 two-level fusions included. There were few statistically significant differences between groups with respect to patient demographics (P > 0.05) with the exception of number of patients who saw the pain management service, which increased from 36.7% (95) pre-protocol to 59.2% (42) post-protocol; P < 0.001. Estimated blood loss (EBL) decreased from 533 ±â€Š571 mL to 346 ±â€Š328 mL (P = 0.003). Percentage of patients who underwent concomitant laminectomy decreased from 71.8% to 49.3% (P < 0.001). Average opioids prescribed on discharge in the pre-protocol period was 534 ±â€Š425 MME, compared to after initiation of the protocol, that is 320 ±â€Š174 MME (P < 0.001). There was no statistically significant difference with respect to satisfaction with pain control, 4.49 ±â€Š0.85 pre-protocol versus 4.51 ±â€Š0.82 post-protocol (P = 0.986). CONCLUSION: A reduction in opioids prescribed at discharge after one- or two-level lumbar fusion is not associated with any statistically significant change in patient satisfaction with pain management, as measured by the HCAHPS survey.Level of Evidence: 3.

The efficacy of intra-articular injections in the treatment of knee osteoarthritis: A network meta-analysis of randomized controlled trials.

PURPOSE: Osteoarthritis (OA) is a debilitating joint disease characterized by progressive loss of articular cartilage. Intra-articular injections are a mainstay of nonoperative treatment, however, there is controversy as to the optimal injectable for these patients. The purpose of the current study is to perform a network meta-analysis of the randomized control trials in the literature to ascertain whether there is a superior injectable nonoperative treatment for knee OA. METHODS: The literature search was conducted based on the PRISMA guidelines. Randomized control trials (RCTs) evaluating intra-articular injectables in osteoarthritic knees were included. Data was extracted and Visual Analogue Scale (VAS) scores and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, where available were analyzed at 1, 3, 6 and 12 months. Clinical outcomes were compared using a frequentist approach to network meta-analysis, with statistical analysis performed using R. The treatment options were ranked using the P-Score. RESULTS: Seventy-nine RCTs with 8761 patients were included in this review. Intra-articular injectables evaluated included autologous conditioned serum (ACS), bone marrow aspirate concentrate (BMAC), botulinum toxin, corticosteroids (CS), hyaluronic acid (HA), mesenchymal stem cells (MSC), ozone, saline placebo, platelet-rich plasma (PRP), plasma rich in growth factor (PRGF), and stromal vascular fraction (SVF). At 4-6 weeks and 3 months of follow-up, the treatment with the highest P-Score for WOMAC score was high molecular weight (HMW) HA + CS [P-Score = 0.9500 and 8503, respectively]. At 6-months follow-up, the treatment with the highest P-Score for WOMAC score was PRP [P-Score = 0.7676]. At all post-injection time points, the treatment with the highest P-Score for VAS score [P-Score Range = 0.8631-9927] and Womac score at 12 Months [P-Score = 0.9044] was SVF. CONCLUSIONS: The current evidence shows that SVF injections result in the greatest improvement in pain and functional outcomes in patients with knee OA at up to 1 year of follow-up.

High Return to Sport in Patients Over 45 Years of Age Undergoing Osteochondral Allograft Transplantation for Isolated Chondral Defects in the Knee.

OBJECTIVE: The purpose of this study was to evaluate the efficacy of osteochondral allograft (OCA) in patients older than 45 years of age, particularly with respect to return to sport. DESIGN: A retrospective review was performed to evaluate patients greater than 45 who underwent an OCA for a symptomatic osteochondral defect of the knee between June 2011 and January 2019. RESULTS: Overall, there were 18 patients (76% male) that met our inclusion and exclusion criteria. Follow-up was attained in 14 of these patients (78%). The mean age of patients included was 52.6 years (48-57) with a mean of 37 months of follow-up (18-60). Visual Analogue Scale scores decreased significantly from the preoperative baseline to final follow-up (7.7 ± 1.7 vs. 2.0 ± 2.0, P < 0.01). Furthermore, the mean Visual Analogue Scale while playing sport was 3.4 ± 3.2, and the mean Knee Injury and Osteoarthritis Outcome Score was 77.5 ± 12.7 at final follow-up. Overall, 11 patients (78.6%) were able to return to their desired sport. No clinical failures were identified during the follow-up period. CONCLUSION: In our series of patients 45 years and older who were treated with OCA for focal osteochondral injuries of the knee, we found a significant improvement in clinical outcome scores at a midterm follow-up of 37 months with no revision OCA procedures or conversion to any form of knee arthroplasty. In addition, a high percentage of patients were able to return to their preferred level of athletic activity.

Institutional Reductions in Opioid Prescribing Following Hip Arthroscopy Do Not Change Patient Satisfaction Scores.

PURPOSE: To investigate what effect decreased opioid prescribing following hip arthroscopy had on Press-Ganey satisfaction survey scores. METHODS: A retrospective review of prospectively collected data was conducted on patients who underwent primary hip arthroscopy for femoroacetabular impingement between October 2014 and October 2019. Inclusion criteria consisted of complete Press-Ganey survey information, no history of trauma, fracture, connective tissue disease, developmental hip dysplasia, autoimmune disease, or previous hip arthroscopy. Groups were separated based on date of surgery relative to implementation of an institutional opioid reduction policy that occurred in October 2018. Prescriptions were converted to milligram morphine equivalents (MME) for direct comparison between different opioids. RESULTS: A total of 113 patients met inclusion criteria, 88 preprotocol and 25 postprotocol. There were no statistically significant differences between groups with respect to patient demographics or intraoperative pathologies (P > .05). Average opioid prescription dropped from 249.6 ± 152 MME (equivalent to 33.3 tablets of oxycodone 5 mg) preprotocol to 108.6 ± 84.7 MME (equivalent to 14.5 tablets of oxycodone 5 mg) postprotocol; P = .0002. There were no statistically significant differences in Press-Ganey survey scores between pre- and postprotocol groups (P > .05). CONCLUSIONS: A reduction in opioids prescribed after a hip arthroscopy is not associated with any statistically significant difference in patient satisfaction with pain management, as measured by the Press-Ganey survey. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Patient Satisfaction After Total Hip Arthroplasty Is Not Influenced by Reductions in Opioid Prescribing.

BACKGROUND: Opioids have played an important part in post-operative analgesia, but concerns with associated morbidity and the fate of leftover pills have prompted the creation of opioid-sparing protocols. The purpose of this study is to investigate the impact of the implementation of an opioid-sparing protocol on survey-based patient satisfaction scores following total hip arthroplasty (THA). METHODS: This study is a retrospective review of prospectively collected data on patients who underwent primary THA between November 2014 and July 2019. Inclusion criteria consisted of primary elective THA with complete Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey information. Cohorts were separated based on their date of surgery relative to the start of an institutional opioid-sparing-protocol in October 2018. Discharge prescriptions and refills were recorded on chart review and converted to milligram morphine equivalents (MME) for comparison between different opioids. HCAHPS results were analyzed for percentage of "top box" ratings for comparison between the 2 groups. RESULTS: In total, 1003 patients met inclusion criteria: 804 pre-protocol and 199 post-protocol. Mean length of stay decreased from 1.74 ± 1.03 to 1.50 ± 1.11 days (P < .001). Pre-operative Visual Analog Scale pain decreased from 7.00 ± 2.30 to 6.41 ± 2.66 (P = .011) as did the rate of opioid refills (15.6%-9.1%; P = .019). Quantity of opioid medication prescribed upon discharge also decreased from 432 ± 298 to 114 ± 156 MME (P < .001). There was no change in "top box percentages" for satisfaction with pain control (79.7% pre-protocol, 82.1% post-protocol; P = .767). There was a significant increase in proportion of patients reporting top box satisfaction with their overall surgical experience after protocol implementation (88.2%-94.0%; P = .018). CONCLUSION: A reduction in opioids prescribed after THA is not associated with a decrease in patient satisfaction with regard to pain control, as measured by the HCAHPS survey, nor is it associated with an increase in post-operative opioid refills. LOE: III. CLINICAL RELEVANCE: This study suggests that HCAHP scores are not negatively impacted by a reduction in post-operative opioid analgesics.

Reduced opioid prescribing following arthroscopic meniscectomy does not negatively impact patient satisfaction.

BACKGROUND: Prior research has demonstrated that physician desire to optimize patient satisfaction is a cause of over-prescription of opioid medications in the healthcare setting. The purpose of this study was to investigate what effect, if any, decreased opioid prescribing following arthroscopic meniscectomy had on Press-Ganey (PG) satisfaction survey scores. METHODS: A retrospective review of prospectively-collected data was conducted on patients who underwent arthroscopic meniscectomy between October2014-October2019. Inclusion criteria consisted of complete PG information, no history of trauma, connective tissue disease, or prior knee surgery. Groups were separated based on date of surgery relative to implementation of an institutional opioid reduction policy which occurred on October 1, 2018. Prescriptions were converted to milligram-morphine-equivalents (MME) for direct comparison between opioids. Minimal-Detectable-Change (MDC) was calculated to evaluate clinical significance of any statistically significant findings. RESULTS: 554 patients were included in this analysis (452pre-protocol, 102post-protocol). The groups did not differ statistically (p > 0.05) with respect to any patient demographics (age, BMI, sex, prior opioid use, opioid naivete) with the exception of smoking history; 54.4% in the pre-protocol group and 32.4%in the post-protocol group; p < 0.001. Mean discharge dose for the pre-protocol group was 229.3 ± 141MME, and 80.05 ± 82.7MME post-protocol; P < 0.0001. There were no statistically significant differences between pre-and-post-protocol satisfaction with pain control scores; P = 0.15. The differences between satisfaction with pain control did not meet clinical or statistical significance, based on a calculated MDC = 0.368. Among pre-protocol patients, 372(82.3%) gave a "top box" response to the question "degree-to-which-your-pain-was-controlled", compared to 91(89.2%) from the post-protocol group; P = 0.10. CONCLUSION: A reduction in opioids prescribed after arthroscopic meniscectomy was not associated with any difference in patient satisfaction with pain management, as measured by the Press-Ganey survey. LOE: 3.

Return-to-Play and Rehabilitation Protocols Following Isolated Meniscal Repair-A Systematic Review.

PURPOSE: To systematically review the literature and assess the reported rehabilitation protocols, return-to-play guidelines, and reported rates of return-to-play after meniscal repair. METHODS: MEDLINE, EMBASE, and the Cochrane Library were searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify studies on meniscal repair. Studies were included if return-to-play data and/or rehabilitation protocols were reported. The rate and timing of return-to-play was assessed. The rehabilitation protocols were documented, in addition to when to start range of motion (ROM), full ROM, partial weight-bearing (WB), and full WB. RESULTS: Overall, 88 studies met our inclusion criteria. Thirteen studies, including 507 patients, cited a range of 71.2% to 100% of return-to-play, with 53.9% to 92.6% returning to the same/greater level, ranging between 3.3 and 10 months. There was considerable variability in the reported rehabilitation protocols, but the most frequently reported time to begin ROM exercises was within the first week (78.9%) and full ROM at 6 weeks (33.3%). Partial WB was typically begun during the first week (61.0%), and full WB between the fourth and sixth week (65.6%) postoperatively. Following surgery, time elapsed was the most commonly cited criteria for return-to-play (97.0%), with 6 months being the most common time point applied (46.9%). No study advised against returning to competitive or contact sports after meniscal repair. CONCLUSIONS: In conclusion, there was a high rate of return-to-play following meniscal repair, with 60% of patients returning to the same level of play. However, there was considerable diversity in the reported rehabilitation protocols and insufficient reporting on return-to-play criteria in the literature. This demonstrates the need for further research and formulation of an evidence-based consensus statement for this patient population. LEVEL OF EVIDENCE: Level IV, systematic review of Level I to IV studies.

Return to Play After Arthroscopic Stabilization for Posterior Shoulder Instability-A Systematic Review.

PURPOSE: To ascertain the rate and timing of return to play (RTP) and the availability of specific criteria for safe RTP after arthroscopic posterior shoulder stabilization. METHODS: Medline, EMBASE, and the Cochrane Library were searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to find studies on arthroscopic posterior shoulder stabilization. Studies were included if they reported RTP data or rehabilitation protocols and excluded if concomitant procedures influenced the rehabilitation protocol. Rate and timing of RTP, along with rehabilitation protocols, were assessed. RESULTS: This review found 25 studies, including 895 cases, meeting the study's inclusion criteria. The majority of patients were male (82.7%), with an age range of 14 to 66 years and a follow-up range of 4 to 148.8 months. The overall RTP rate ranged from 62.7% to 100.0%, and 50.0% to 100.0% returned to the same level of play. Among collision athletes, the overall rate of RTP was 80.0% to 100.0%, with 69.2%-100.0% returning to the same level of play. In overhead athletes, the overall rate of RTP was 85.2% to 100.0%, with 55.6% to 100.0% returning to the same level of play. Four studies (128 patients) specifically addressed the timing of RTP, and the range to RTP was 4.3 to 8.6 months. Specific RTP criteria were reported in a majority of studies (60%), with the most reported item being restoration of strength (44%). CONCLUSION: There is a high rate of return to sport after arthroscopic posterior shoulder stabilization, ranging from 4.3 to 8.6 months after surgery. Return to preinjury level is higher for collision athletes compared with overhead athletes. However, there is inadequate reporting of RTP criteria in the current literature, with no clear timeline for when it is safe to return to sport. LEVEL OF EVIDENCE: IV, systematic review of level II to IV studies.

Return to play criteria among shoulder surgeons following shoulder stabilization.

PURPOSE: The purpose of this study was to survey the members of North American and European shoulder surgery and sports medicine societies to evaluate their criteria for deciding when an athlete can safely return to play (RTP) following shoulder stabilization surgery. METHODS: A survey was sent to the members of the American Shoulder and Elbow Surgeons (ASES), American Orthopaedic Society for Sports Medicine (AOSSM), European Society for Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA), and European Society for Surgery of the Shoulder and the Elbow (SECEC). Surgeons were asked which criteria they used to determine when an athlete can return to play following the arthroscopic Bankart repair and Latarjet procedures, with additional questions on how time from surgery and participation in collision sports affect return. RESULTS: Overall, 317 surgeons responded to the survey. Following arthroscopic Bankart repair, the most common criteria used were time (98.7%), strength (74.8%), and range of motion (70%). The most commonly reported time point was 4 months (43.8%), and the majority used an additional time period, most commonly 2 months (38.2%), before allowing a collision athlete to return to play (75.4%). Interestingly, the addition of a remplissage procedure did not affect decision making regarding RTP in most cases (92.1%). Following the Latarjet procedure, the most common criteria used were time (98.4%), strength (67.5%), and range of motion (65.9%). Less than half reported using imaging to assess for radiographic union before allowing patients to return to play (47%), and the most common modality was plain radiography (80%). The most common time point was 4 months (33.1%), and the majority reported waiting an additional period of time, most commonly by 2 months (25.9%), before allowing a collision athlete to return to play (59.6%). CONCLUSION: Despite the absence of evidence-based guidelines on when athletes can safely return to play following shoulder stabilization surgery, there exists minimal variability in recommendations between North American and European shoulder surgeons. Further research is required to better define criteria for RTP after the arthroscopic Bankart repair and Latarjet procedures.

Management of Meniscal Pathology: From Partial Meniscectomy to Transplantation.

Meniscal pathology is one of the most common structural knee issues seen and managed by the orthopaedic surgeon. An ever-evolving armamentarium of management options exists that are geared toward the elimination of symptoms and restoration of normal knee function. A common theme among these management options is to preserve meniscal tissue whenever possible through repair or minimization of meniscal excision, as the literature has shown that the loss of meniscal tissue can significantly alter the distribution of forces and contact stresses on knee articular cartilage, thus predisposing the joint to degenerative osteoarthritis. In the setting of meniscal injuries or insufficiency, various advances in repair techniques, use of meniscal allografts, and use of biologic adjuvants have been reported to help preserve and/or attempt to restore the native kinematic properties of the knee. It is important to explore meniscal function, its associated pathologies, and currently available treatment options that are supported by short-term and long-term clinical data.

Return-to-Play and Rehabilitation Protocols following Cartilage Restoration Procedures of the Knee: A Systematic Review.

OBJECTIVE: The purpose of this study is to systematically review the literature and to evaluate the reported rehabilitation protocols, return-to-play guidelines, and subsequent rates of return to play following cartilage restoration procedures in the knee. DESIGN: MEDLINE, EMBASE, and the Cochrane Library were searched according to the PRISMA guidelines to find studies on cartilage restoration procedures in the knee, including (1) microfracture (Mfx), (2) osteochondral autograft transfer (AOT), (3) osteochondral allograft implantation (OCA), and (4) autologous chondrocyte implantation (ACI). Studies were included if they reported return-to-play data or rehabilitation protocols. RESULTS: Overall, 179 studies fit our inclusion criteria, with 48 on Mfx, 34 on AOT, 54 on OCA, and 51 on ACI. The rate of return to play was reported as high as 88.2% with AOT, and as low as 77.2% following OCA, with rates of return to play at the same/higher level as high as 79.3% with AOT, and as low as 57.3% following ACI. The average reported time of return to play was as low as 4.9 months with AOT, and as high as 11.6 months following ACI. CONCLUSIONS: The majority of patients are able to return to play following cartilage restoration procedures in the knee, regardless of surgical procedure utilized. However, while the rate of return to play at the same level was similar to the overall rate of return following AOT, there was a large number of patients unable to return to the same level following Mfx, OCA, and ACI. Additionally, there is wide variety in the rehabilitation protocols, and scant literature on return-to-play protocols.

A Comparison of Immunosuppression Regimens in Hand, Face, and Kidney Transplantation.

BACKGROUND: Authors have speculated that vascularized composite allotransplantation (VCA) recipients may require greater maintenance immunosuppression than solid organ transplant (SOT) recipients due to the higher antigenicity of skin. However, detailed comparisons of VCA and SOT immunosuppression regimens have been limited. METHODS: Hand and face VCA recipient immunosuppression data were collected through a systematic literature review. Kidney recipient data were obtained through a retrospective chart review of the authors' institution. Prednisone and mycophenolate mofetil (MMF) doses were compared between VCA and kidney recipients at predefined follow-up intervals (<1, 1-5, and >5 y). Tacrolimus target trough levels (TTTL) were compared at follow-up intervals of 1-5 and >5 y, and stratified into our institution's kidney transplant risk-based target ranges (4-6 ng/mL, 6-8 ng/mL) or higher (>8 ng/mL). RESULTS: Immunosuppression data were available for 57 VCA and 98 kidney recipients. There were no significant differences in prednisone doses between groups at all follow-up intervals. VCA recipient mean MMF dose was significantly greater at <1-y (1.71 ± 0.58 versus 1.16 ± 0.55 gm/d; P = 0.01). For VCA recipients, there was a significant difference (P = 0.02) in TTTL distribution over the three predefined therapeutic ranges (4-6 ng/mL, 6-8 ng/mL, and >8 ng/mL) between 1 and 5 y (24.0%, 20.0%, 56.0%, respectively) and >5 y (28.6%, 42.9%, 28.6%). CONCLUSIONS: At longer follow-up, VCA and kidney recipients receive comparable MMF/prednisone doses, and most VCA recipients are treated with TTTL similar to kidney recipients. Further research may improve our understanding of VCA's complex risk/benefit ratio, and enhance informed consent.
