Category: Midfoot/Forefoot Introduction/Purpose: Studies have shown that sesamoidectomy provides good clinical outcomes and quick return to sporting activities, however, there is concern regarding the complications following resection of one or both sesamoid bones. The purpose of the current systematic review was to evaluate the current evidence on sesamoidectomy for the treatment of the hallux sesamoid disorders. Methods: A systematic search of MEDLINE, EMBASE and Cochrane Library databases was performed 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. Reporting outcome data, clinical outcomes, and percentage of patients who returned to sport at previous level were also evaluated. Results: Ten studies with total 196 feet were included. The weighted mean age was 36.6 ± 11.0 with a mean follow-up of 45.1 ± 19.3 months. The mean Visual Analogue Scale score improved from a mean score of 6.5 ± 0.3 to 1.2 ± 0.5. The mean postoperative AOFAS score was 92.7 ± 2.7. Six studies demonstrated that 94.4% of patients returned to sport, with 90.0% returning to previous level, at a mean of 11.8 ± 1.8 weeks. The mean hallux valgus angle increased from 13.1 ± 2.1 preoperatively to 14.8 ± 3.7 postoperatively (p=0.470), and the mean intermetatarsal angle increased from 8.7 ± 0.8 to 9.7 ± 0.8 (p=0.180) following medial sesamoidectomy. The overall complication rate was 22.5%, and further surgeries were required in 3.0%(Table). Conclusion: The current systematic review demonstrated that sesamoidectomy for the hallux sesamoids disorders yields good clinical outcomes and a high rate of return to sports activity in the short-term. It is important to note however the high complications rate after sesamoidectomy, with a 22.5% complication rate in the short-term follow-up.

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.

Background: Studies on the clinical outcomes of derotational femoral osteotomy to treat recurrent patellar dislocation in the presence of increased femoral anteversion are limited. Purpose: To investigate the role of derotational femoral osteotomy in the treatment of recurrent patellar dislocation in the presence of increased femoral anteversion. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was performed according to the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses) by searching the Medline, Embase, Web of Science, and Cochrane Library databases through February 10, 2021. Included were studies of skeletally mature patients presenting with recurrent patellar dislocation and exhibiting increased femoral anteversion who subsequently underwent derotational femoral osteotomy. Methodological quality was assessed using the MINORS (Methodological Index for Nonrandomized Studies) score. The basic characteristics of each study were recorded and analyzed: characteristic information, radiological parameters, surgical techniques, patient-reported outcomes, and complications. Results: A total of 6 studies with 163 patients (170 knees) were included. Sample sizes ranged from 7 to 66 patients, and the patients were predominantly women (range, 79%-100%). The mean age and follow-up ranges were 18 to 28 years and 16 to 44 months, respectively. The mean femoral anteversion decreased significantly from 34° preoperatively to 12° postoperatively. In studies reporting pre- and postoperative outcomes, significant improvements were found in the Lysholm score (from 24.8 to 44.1), Kujala score (from 15.8 to 41.9), International Knee Documentation Committee score (from 11.0 to 28.0), and visual analog scale for pain (from 2.0 to 3.7). All studies reported postoperative complications, giving an overall reported complication rate of 4.7%, but no redislocations occurred during the follow-up period. Conclusion: For recurrent patellar dislocation in the presence of increased femoral anteversion, combination treatment with derotational femoral osteotomy led to favorable clinical outcomes with a low redislocation rate. However, there was no consensus among researchers on the indications for derotational femoral osteotomy in the treatment of recurrent patellar dislocation.

AbstractRadiation-induced cavernous malformations (RICMs) are delayed complications of brain irradiation during childhood. Its natural history is largely unknown and its incidence may be underestimated as RCIMS tend to develop several years following radiation. No clear consensus exists regarding the long-term follow-up or treatment. A systematic review of Embase, Cochrane Library, PubMed, Google Scholar, and Web of Science databases, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, was performed. Based on our inclusion/exclusion criteria, 12 articles were included, totaling 113 children with RICMs, 86 were treated conservatively, and 27 with microsurgery. We were unable to precisely define the incidence and natural history from this data. The mean age at radiation treatment was 7.3 years, with a slight male predominance (54%) and an average dose of 50.0 Gy. The mean time to detection of RICM was 9.2 years after radiation. RICM often developed at distance from the primary lesion, more specifically frontal (35%) and temporal lobe (34%). On average, 2.6 RICMs were discovered per child. Sixty-seven percent were asymptomatic. Twenty-one percent presented signs of hemorrhage. Clinical outcome was favorable in all children except in 2. Follow-up data were lacking in most of the studies. RICM is most often asymptomatic but probably an underestimated complication of cerebral irradiation in the pediatric population. Based on the radiological development of RICMs, many authors suggest a follow-up of at least 15 years. Studies suggest observation for asymptomatic lesions, while surgery is reserved for symptomatic growth, hemorrhage, or focal neurological deficits.

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.

Abstract Biochemical remission after transsphenoidal surgery is still unsatisfied in acromegaly patients with macroadenomas, especially with invasive macroadenomas. Concerning the impact of preoperative somatostatin analogues (SSAs) on surgical outcomes, previous studies with limited cases reported conflicting results. To assess current evidence of preoperative medical treatment, we performed a systematic review and meta-analysis of comparative studies. A literature search was conducted in Pubmed, Embase, and the Cochrane Library. Five randomized controlled trials (RCT) and seven non-RCT comparative studies were included. These studies mainly focused on pituitary macroadenomas though a small number of microadenoma cases were included. For safety, preoperative SSAs were not associated with elevated risks of postoperative complications. With respect to efficacy, the short-term cure rate was improved by preoperative SSAs, but the long-term cure rate showed no significant improvement. For invasive macroadenomas, the short-term cure rate was also improved, but the long-term results were not evaluable in clinical practice because adjuvant therapy was generally required. In conclusion, preoperative SSAs are safe in patients with acromegaly, and the favorable impact on surgical results is restricted to the short-term cure rate in macroadenomas and invasive macroadenomas. Further well-designed RCTs to examine long-term results are awaited to update the finding of this meta-analysis.

Category: Midfoot/Forefoot Introduction/Purpose: Hallux rigidus is a common degenerative joint condition of the foot. In advanced stages of the disease, extensive procedures have been utilized including Keller arthroplasty, interpositional arthroplasty (IPA), arthrodesis, total joint replacement or synthetic cartilage replacement. IPA is a surgical procedure that attempts to maintain joint motion through insertion of a biologic spacer into the joint. However, there is still a paucity of overall clinical data regarding outcomes and complication rates following IPA procedure for the treatment of hallux rigidus.The purpose of the current study was to systematically review the outcomes of IPA in the treatment of hallux rigidus. Methods: A systematic search of the MEDLINE, EMBASE and Cochrane Library databases was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Outcomes collected and analysed included: AOFAS score, VAS score, SF36 score, range of motion, radiographic parameters, and postoperative complications. The level and quality of evidence were recorded and assessed. Results: Sixteen studies with a total of 433 patients met inclusion/exclusion criteria. The mean AOFAS improved from 56.8±7.3 (range, 43.2-64.3) preoperatively to 84.0±6.7 (range, 71.6-90.0) postoperatively. The preoperative weighted mean total ROM was 37.7±16.2 degrees and the postoperative weighted mean total ROM was 60.3±13.4 degrees. Five studies examined joint space narrowing on plain radiographs. The mean preoperative joint space was 1.2±0.2 mm (range, 1 -1.5) and the mean postoperative joint space was 2.5±0.5 mm (range, 1.9-3). The complication rate was 18.2% with metatarsalgia as the most commonly reported complication. One study was Level III and 15 studies were Level IV. Conclusion: This systematic review demonstrates improvement in functional and ROM outcomes following IPA. The procedure however has a high complication rate. There is a low level and quality of evidence in the current literature with inconsistent reporting of data. Therefore, further well designed studies must be carried out to determine the efficacy of IPA in the treatment of hallux rigidus.

Background. Gastric electrical stimulation (GES) is a surgically implanted treatment option for refractory gastroparesis.Aim. To systematically appraise the current evidence for the use of gastric electrical stimulation and suggest a method of standardisation of assessment and follow-up in these patients.Methods. A systematic review of PubMed, Web of Science, DISCOVER, and Cochrane Library was conducted using the keywords including gastric electrical stimulation, gastroparesis, nausea, and vomiting and neuromodulation, stomach, central nervous system, gastric pacing, electrical stimulation, and gastrointestinal.Results. 1139 potentially relevant articles were identified, of which 21 met the inclusion criteria and were included. The quality of studies was variable. There was a variation in outcome measures and follow-up methodology. Included studies suggested significant reductions in symptom severity reporting over the study period, but improvements in gastric emptying time were variable and rarely correlated with symptom improvement.Conclusion. The evidence in support of gastric electrical stimulation is limited and heterogeneous in quality. While current evidence has shown a degree of efficacy in these patients, high-quality, large clinical trials are needed to establish the efficacy of this therapy and to identify the patients for whom this therapy is inappropriate. A consensus view on essential preoperative assessment and postoperative measurement is needed.

Abstract Purpose This prospective cohort study reports on a new technique, namely precise safety decompression via double percutaneous lumbar foraminoplasty (DPLF) and percutaneous endoscopic lumbar decompression (PELD) for lateral lumbar spinal canal (LLSC) stenosis, and its short-term clinical outcomes.Methods The study analyzed 69 patients with single-level LLSC stenosis simultaneously occurring in both zones 1 and 2 (defined as retrodiscal space and upper bony lateral recess respectively by new LLSC classification) who underwent DPLF–PELD from November 2018 to April 2019. Clinical outcomes were evaluated according to preoperative, three months postoperatively, and last follow-up, via leg pain/low back pain (LBP) visual analog scale (VAS) scores, Oswestry disability index (ODI) scores, and the Macnab criteria. The postoperative MRI and CT were used to confirm the complete decompression, and flexion-extension x-rays at the last follow-up were used to observe lumbar stability.Results All patients successfully underwent DPLF–PELD, and the stenosis was completely decompressed, confirmed by postoperative MRI and CT. The mean follow-up duration was 13 months (range: 8–17 months). The mean preoperative leg pain VAS score is 7.05 ± 1.04 (range 5–9), which decreased to 1.03 ± 0.79(range: 0–3) at three months postoperatively and to 0.75 ± 0.63 (range: 0–2) by the last follow-up visit(p < 0.05). The mean preoperative ODI was 69.8 ± 9.05 (range: 52–85), which decreased to 20.3 ± 5.52 (range: 10–35) at the third month postoperatively and to 19.6 ± 5.21 (range: 10–34) by the final follow-up visit(p < 0.05). The satisfactory (excellent or good) results were 94.2%. There was one patient with aggravated symptoms, which were relieved after an open surgery. Two patients had a dural tear, and two patients suffered postoperative LBP. No recurrence or segmental instability was observed at the final follow-up.Conclusion DPLF–PELD could be a good alternative for the treatment of LLSC stenosis patients whose stenosis occurred in both zones 1 and 2.Trial registration Chinese Clinical Trial Registry (ChiCTR1800019551).

Background: The optimal timing of surgical intervention for multiligament knee injuries remains controversial. Purpose: To review the clinical and functional outcomes after acute and delayed surgical intervention for multiligament knee injuries. Study Design: Systematic review; Level of evidence, 4. Methods: We performed a search of the PubMed, Embase, Cochrane Library, and Web of Science databases from inception to September 2020. Eligible studies reported on knee dislocations, multiligament knee injuries, or bicruciate ligament injuries in adult patients (age, ≥18 years). In addition to comparing outcomes between acute and delayed surgical intervention groups, we conducted 3 subgroup analyses for outcomes within isolated knee injuries, knee injuries with concomitant polytrauma/fractures, and high-level (level 2) studies. Results: Included in the analysis were 31 studies, designated as evidence level 2 (n = 3), level 3 (n = 8), and level 4 (n = 20). These studies reported on 2594 multiligament knee injuries sustained by 2585 patients (mean age, 25.1-65.3 years; mean follow-up, 12-157.2 months). At the latest follow-up timepoint, the mean Lysholm (n = 375), International Knee Documentation Committee (IKDC) (n = 286), and Tegner (n = 129) scores for the acute surgical intervention group were 73.60, 67.61, and 5.06, respectively. For the delayed surgical intervention group, the mean Lysholm (n = 196), IKDC (n = 172), and Tegner (n = 74) scores were 85.23, 72.32, and 4.85, respectively. The mean Lysholm (n = 323), IKDC (n = 236), and Tegner (n = 143) scores for our isolated subgroup were 83.7, 74.8, and 5.0, respectively. By comparison, the mean Lysholm (n = 270), IKDC (n = 236), and Tegner (n = 206) scores for the polytrauma/fractures subgroup were 83.3, 64.5, and 5.0, respectively. Conclusion: The results of our systematic review did not elucidate whether acute or delayed surgical intervention produced superior clinical and functional outcomes. Although previous evidence has supported acute surgical intervention, future prospective randomized controlled trials and matched cohort studies must be completed to confirm these findings.
