Background: Whereas there has been growing interest in surgical repair of posterior medial meniscus root tears (PMMRTs), our understanding of the medium- and long-term results of this procedure is still evolving. Purpose: To report midterm clinical outcomes from PMMRT repairs. Study Design: Systematic review. Methods: A literature review for this systematic analysis was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We identified studies that reported the results of arthroscopic repair of PMMRTs. Functional and imaging outcomes were reviewed and summarized. Results: In total, 28 studies with a total of 994 patients (83% female) with an overall mean age of 57.1 were included in this review. Clinical outcomes (Lysholm, International Knee Documentation Committee, Hospital for Special Surgery, and Tegner scores) were improved at final follow-up in all studies. Of patients, 49% had radiographic progression of at least 1 grade in the Kellgren-Lawrence scale at a mean follow-up of 4.0 years in 11 studies. Cartilage degeneration had progressed at least 1 grade on magnetic resonance imaging scans in 23% of patients at a mean follow-up of 31.6 months in 4 studies. Conclusion: PMMRT repairs provide a functional benefit with consistent improvements in clinical outcome scores. There is some evidence that PMMRT repair slows the progression of osteoarthritis but does not prevent it at midterm follow-up.

AbstractThe objective of this study was to examine the association between preoperative meniscal extrusion of patients undergoing partial medial meniscectomy with clinical outcomes and progression of osteoarthritis and to determine the extent of meniscal extrusion associated with unsatisfactory clinical outcomes and progression of osteoarthritis. Ninety-five patients who underwent partial medial meniscectomy with a minimum follow-up of 5 years were retrospectively reviewed. Preoperative meniscal extrusion was evaluated with magnetic resonance imaging. Patients were assessed preoperatively and postoperatively with Lysholm and International Knee Documentation Committee (IKDC) subjective scores for clinical outcomes and with IKDC radiographic scale for osteoarthritis. An ANOVA (Analysis of Variance) was used to analyze the variations in meniscal extrusion and the clinical and radiological outcomes. A regression analysis was performed to identify factors that affect preoperative medial meniscus extrusion and that influence results after partial meniscectomy. An optimal cutoff value for meniscal extrusion associated with unsatisfactory clinical outcomes and progression of osteoarthritis was established. Significance was set at p < 0.05. The mean ± SD preoperative and postoperative Lysholm scores were 59.6 ± 15.5 versus 83.8 ± 13.1 (p < 0.001) and the mean preoperative and postoperative IKDC subjective scores were 59.4 ± 16.8 versus 82.0 ± 15.8 (p < 0.001). Meniscal extrusion greater than 2.2 mm (sensitivity, 84%; specificity, 81%) and 2.8 mm (sensitivity, 73%; specificity, 85%) was associated with unsatisfactory (poor/fair) Lysholm and IKDC subjective scores, respectively. The progression of osteoarthritis, characterized as a change of at least one category on the IKDC radiographic scale, occurred when meniscal extrusion was greater than 2.2 mm (sensitivity, 63%; specificity, 75%). Patients with higher body mass index (BMI) had significantly greater meniscal extrusion that patients with normal BMI (p < 0.001). The medial meniscus was more extruded in patients with horizontal and root tears. In conclusion, patients with preoperative meniscal extrusion of 2.2 mm or greater had unsatisfactory clinical outcomes and progression of osteoarthritis after partial medial meniscectomy at a minimum of 5 years follow-up. Higher BMI and horizontal and root tears were associated with greater preoperative meniscal extrusion.

Systematic Analysis

Primary total hip arthroplasty (THA) is one of the most successful surgical procedures. Considering the demographic change the use of new ultra-short femoral implants has gained importance especially when treating young patients. Main features are bone conservation, metaphyseal anchoring and thus reducing stress shielding by proximal load transferring. The objective of this study is to give an overview over the subject of femoral neck prostheses. A systematic review was conducted. A total number of 27 publications were taken into this systematic review. Over all, just a few follow-up, biomechanical and radiostereometric studies have been conducted in the past. Still no long-term results (>10 years of follow-up) are available. The available mid-term results indicate unsatisfactory survival rates. Aseptic loosening was the most common reason for revision. Valgus angle and good bone mineral density were considered to be crucial for primary stability of femoral neck prostheses. Register data report a very low percentage of femoral neck prostheses in THA with even more diminishing implantation rates. To conclude, further studies are necessary in order to provide evidence-based recommendations. Currently, due to the inhomogeneous and poor data a reasonable and legitimate recommendation cannot be given.

Objective To perform a systematic review of clinical outcomes following microfracture augmented with biological adjuvants (MFX+) compared with microfracture (MFX) alone. Design The MEDLINE, Scopus, and Cochrane databases were searched for clinical studies on MFX+ for chondral defects of the knee. Study characteristics and clinical outcome score data were collected. Subjective synthesis was performed using data from randomized controlled studies to determine effect size of MFX+ procedures performed with either injectable or scaffold-based augmentation compared with MFX alone. Results A total of 18 articles reporting on 625 patients (491 MFX+, 134 MFX) were identified. Six studies were level II evidence and 1 study was level I evidence. Mean patient age range was 26 to 51 years, and mean follow-up ranged from 2 to 5 years. All studies demonstrated significant improvement in reported clinical outcome scores at follow-up after MFX+ therapy, and 87% of patients reported satisfaction with treatment. The most commonly reported treatment complication was postoperative stiffness (3.9% of patients). Subjective synthesis on randomized controlled trials demonstrated that 2/2 injectable MFX+ interventions had significantly greater improvements in International Knee Documentation Committee Subjective Knee Form (IKDC; P = 0.004) and Knee injury and Osteoarthritis Outcome Score (KOOS; P = 0.012) scores compared with MFX alone, while 2/2 trials on scaffolding MFX+ adjuvants showed comparable postoperative improvements. Conclusions MFX+ biological adjuvants are safe supplements to marrow stimulation for treating cartilage defects in the adult knee. Early literature is heterogenous and extremely limited in quality. Individual trials report both equivalent and superior clinical outcomes compared with MFX alone, making definitive conclusions on the efficacy of MFX+ difficult without higher quality evidence.

Background: Arthroscopic capsular release (ACR) for the treatment of adhesive capsulitis of the shoulder can be performed in either the beach-chair (BC) or lateral decubitus (LD) position. Purpose: To determine the clinical outcomes and recurrence rates after ACR in the BC versus LD position. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was performed by searching PubMed, Embase, and the Cochrane Library databases for studies reporting clinical outcomes of patients undergoing ACR in either the BC or LD position. All English-language literature from 1990 through 2017 reporting on clinical outcomes after ACR with a minimum 3-month follow-up were reviewed by 2 independent reviewers. Recurrence rates, range of motion (ROM) results, and patient-reported outcome (PRO) scores were collected. Study methodological quality was evaluated using the modified Coleman Methodology Score (MCMS). Results: A total of 30 studies (3 level 1 evidence, 2 level 2 evidence, 4 level 3 evidence, 21 level 4 evidence) including 665 shoulders undergoing ACR in the BC position (38.1% male; mean age, 52.0 ± 3.9 years; mean follow-up, 35.4 ± 18.4 months) and 603 shoulders in the LD position (41.8% male; mean age, 53.0 ± 2.3 years; mean follow-up, 37.2 ± 16.8 months) were included. There were no significant differences in overall mean recurrence rates between groups (BC, 2.5%; LD, 2.4%; P = .81) or in any PRO scores between groups ( P > .05). There were no significant differences in improvement in ROM between groups, including external rotation at the side (BC, 36.4°; LD, 42.8°; P = .91), forward flexion (BC, 64.4°; LD, 79.3°; P = .73), abduction (BC, 77.8°; LD, 81.5°; P = .82), or internal rotation in 90° of abduction (BC, 40.8°; LD, 45.5°; P = .70). Significantly more patients in the BC group (91.6%) underwent concomitant manipulation than in the LD group (63%) ( P < .0001). There were significantly more patients with diabetes in the LD group (22.4%) versus the BC group (9.6%) ( P < .0001). Conclusion: Low rates of recurrent shoulder stiffness and excellent improvements in ROM can be achieved after ACR in either the LD or BC position. Concomitant manipulation under anesthesia is performed more frequently in the BC position compared with the LD position.

Meta Analyses

Background: Benefits of phosphate-lowering interventions on clinical outcomes in patients with chronic kidney disease (CKD) are unclear; systematic reviews have predominantly involved dialysis patients. This study aimed to summarize evidence from randomized controlled trials (RCTs) concerning benefits and risks of non-calcium-based phosphate-lowering treatment in non-dialysis CKD. Methods: We conducted a systematic review and meta-analyses of RCTs involving noncalcium-based phosphate-lowering therapy compared to placebo, calcium-based binders, or no study medication, in adults with CKD not on dialysis or post-transplant. RCTs had ≥3 months follow up and outcomes included biomarkers of mineral metabolism, cardiovascular parameters, and adverse events. Outcomes were meta-analyzed using the Sidik-Jonkman method for random effects. Unstandardized mean differences were used as effect sizes for continuous outcomes, with common measurement units and Hedge's g standardized mean differences (SMD) otherwise. Odds ratios were used for binary outcomes. Cochrane risk of bias and GRADE assessment determined the certainty of evidence. Results: Twenty trials involving 2,498 participants (median sample size 120, median follow up 9 months) were eligible for inclusion. Overall, risk of bias was low. Compared with placebo, non calcium-based phosphate binders reduced serum phosphate (12 trials, weighted mean difference -0.37, 95% CI -0.58,-0.15 mg/dL, low certainty evidence) and urinary phosphate excretion (8 trials, SMD -0.61, 95% CI -0.90,-0.31, low certainty evidence), but resulted in increased constipation (9 trials, log odds ratio [OR] 0.93, 95% CI 0.02, 1.83, low certainty evidence) and greater vascular calcification score (3 trials, SMD 0.47, 95% CI 0.17, 0.77, very low certainty evidence). Data for effects of phosphate-lowering therapy on cardiovascular events (log OR 0.51 [95% CI -0.51, 1.17]) and death were scant. Conclusions: Non-calcium-based phosphate-lowering therapy reduced serum phosphate and urinary phosphate excretion, but there was an unclear effect on clinical outcomes and intermediate cardiovascular end-points. Adequately powered RCTs are required to evaluate benefits and risks of phosphate-lowering therapy on patient-centered outcomes.

Category: Ankle Introduction/Purpose: Autologous osteochondral transplantation (AOT) is an established treatment for large-sized OLT, typically greater than 107mm2. Several studies have demonstrated favourable outcomes following AOT at short- and mid-term follow-up. However, the majority of the literature on AOT has short-term follow-up and little evidence exists on the mid-term and longer-term follow-up. Additionally, few studies include a large number of patients or have a high level of evidence, limiting the ability to draw broad and meaningful conclusions about the effectiveness of the AOT procedure for the treatment of OLT beyond short-term follow-up. The purpose of the current systematic review was to evaluate the clinical outcomes analysing level and quality of evidence of the AOT procedure in the treatment of OLT at mid-term and long-term follow-up. Methods: A systematic search of the MEDLINE, EMBASE and Cochrane Library databases was performed in October 2017 based on the PRISMA guidelines. Included studies were evaluated with regard to level of evidence (LOE) and quality of evidence (QOE) using the Coleman Methodology Score. Clinical outcomes, and complications were also evaluated. Results: Eleven studies, with 500 ankles were included at a mean 62.8 months follow-up. There were 3 studies of LOE III, and 8 studies of LOE IV. There were 3 studies of fair quality and 8 studies of poor quality. The weighted mean preoperative AOFAS score was 55.1 ± 6.1, and the postoperative score was 86.2 ± 4.5, with 87.4% of patients being reported as excellent or good results. In total, 54 of the 500 patients (10.8%) had complications. The most common complication was donor site morbidity with 18 patients (3.6%) at final follow-up. Thirty-one patients (6.2%) underwent reoperations, and the authors deemed a total of 5 ankles (1.0%) failures. Only 5 studies (45.5%) used MRI for follow-up evaluation. Conclusion: The current systematic review demonstrated that good clinical and functional outcomes can be expected following AOT procedure for the treatment of OLT, with a failure rate of only 1.0% at 63 months follow-up. MRI and radiographs showed restoration of articular surface as well as a minimal presence of osteoarthritis at mid-term follow-up. However, there is still lack of data from high LOE and QOE studies, and further high quality studies are necessary.

Objective To perform a systematic review of clinical outcomes following microfracture (MFX), autologous chondrocyte implantation (ACI), osteochondral allograft transplantation (OCA), and osteochondral autograft transplantation system (OATS) to treat articular cartilage lesions in pediatric and adolescent patients. We sought to compare postoperative improvements for each cartilage repair method to minimal clinically important difference (MCID) thresholds. Design MEDLINE, Web of Science, Scopus, and Cochrane Library databases were searched for studies reporting MCID-validated outcome scores in a minimum of 5 patients ≤19 years treated for symptomatic knee chondral lesions with minimum 1-year follow-up. One-sample t tests were used to compare mean outcome score improvements to established MCID thresholds. Results Twelve studies reporting clinical outcomes on a total of 330 patients following cartilage repair were identified. The mean age of patients ranged from 13.7 to 16.7 years and the mean follow-up was 2.2 to 9.6 years. Six studies reported on ACI, 4 studies reported on MFX, 2 studies reported on OATS, and 1 study reported on OCA. ACI ( P < 0.001, P = 0.008) and OCA ( P < 0.001) showed significant improvement for International Knee Documentation Committee (IKDC) scores with regard to MCID while MFX ( P = 0.66) and OATS ( P = 0.11) did not. ACI ( P < 0.001) and OATS ( P = 0.010) both showed significant improvement above MCID thresholds for Lysholm scores. MFX ( P = 0.002) showed visual analog scale (VAS) pain score improvement above MCID threshold while ACI ( P = 0.037, P = 0.070) was equivocal. Conclusions Outcomes data on cartilage repair in the pediatric and adolescent knee are limited. This review demonstrates that all available procedures provide postoperative improvement above published MCID thresholds for at least one reported clinical pain or functional outcome score.

OBJECTIVEA direct comparison of endovascular versus microsurgical treatment of ruptured middle cerebral artery (MCA) aneurysms in randomized trials is lacking. As endovascular treatment strategies continue to evolve, the number of reports of endovascular treatment of these lesions is increasing. Herein, the authors report a detailed post hoc analysis of ruptured MCA aneurysms treated by microsurgical clipping from the Barrow Ruptured Aneurysm Trial (BRAT).METHODSThe cases of patients enrolled in the BRAT who underwent microsurgical clipping for a ruptured MCA aneurysm were reviewed. Characteristics of patients and their clinical outcomes and long-term angiographic results were analyzed.RESULTSFifty patients underwent microsurgical clipping of a ruptured MCA aneurysm in the BRAT, including 21 who crossed over from the endovascular treatment arm. Four patients with nonsaccular (e.g., dissecting, fusiform, or blister) aneurysms were excluded, leaving 46 patients for analysis. Most (n = 32; 70%) patients presented with a Hunt and Hess grade II or III subarachnoid hemorrhage, with a high prevalence of intraparenchymal blood (n = 23; 50%), intraventricular blood (n = 21; 46%), or both. At the last follow-up (up to 6 years after treatment), clinical outcomes were good (modified Rankin Scale score 0–2) in 70% (n = 19) of 27 Hunt and Hess grades I–III patients and in 36% (n = 4) of 11 Hunt and Hess grade IV or V patients. There were no instances of rebleeding after the surgical clipping of aneurysms in this series at the time of last clinical follow-up.CONCLUSIONSMicrosurgical clipping of ruptured MCA aneurysms has several advantages over endovascular treatment, including durability over time. The authors report detailed outcome data of patients with ruptured MCA aneurysms who underwent microsurgical clipping as part of a prospective, randomized trial. These results should be used for comparison with future endovascular and surgical series to ensure that the best results are being achieved for patients with ruptured MCA aneurysms.
