Background: Beach volleyball officially became a National Collegiate Athletic Association (NCAA) Division I sport in 2015-2016. Few studies have examined the epidemiology of injuries in indoor versus beach volleyball in NCAA Division I athletes. Purpose: To compare the epidemiology of injuries and time lost from participation between female NCAA Division I athletes who participate in indoor versus beach volleyball. Study Design: Cohort study; Level of evidence, 3. Methods: Injury surveillance data (2003-2020) were obtained using an institutional database for all NCAA Division I women’s beach or indoor volleyball athletes. The total injury rate was expressed per 1000 hours played. The injury rate per body site was calculated by dividing the number of injuries in each body region by the total number of injuries. The frequency of injury per body site was also expressed as number of injuries per 1000 hours of practice or number of injuries per 1000 hours of game. The injury rate (total and per body site) and time lost from participation were compared between indoor and beach volleyball athletes. Results: Participants were 161 female NCAA Division I volleyball athletes (53 beach volleyball and 108 indoor volleyball athletes). In total, 974 injuries were recorded: 170 in beach volleyball and 804 in indoor volleyball. The injury rates for beach versus indoor volleyball were 1.8 versus 5.3 injuries per 1000 hours played ( P < .0001). Indoor volleyball athletes had significantly higher injury rates compared with beach volleyball players for concussion (7.5% vs 6.5%; P < .0001) and knee injury (16.7% vs 7.6%; P = .0004); however, the rate of abdominal muscle injury was significantly higher in beach versus indoor volleyball (11.8% vs 4.7%; P = .0008). Time lost from sport participation was significantly longer in beach versus indoor volleyball for knee (24 vs 11 days; P = .047), low back (25 vs 17 days; P = .0009), and shoulder (52 vs 28 days; P = .001) injuries. Conclusion: Based on this study, injury was more likely to occur in indoor compared with beach volleyball. Sport-related concussion and knee injuries were more common in indoor volleyball, but the rate of abdominal muscle injury was higher in beach volleyball. Beach volleyball players needed longer time to recover after injuries to the knee, low back, and shoulder.
Ehlers-Danlos Syndrome (EDS) is a hereditary disorder of the connective tissue, which has been classified into numerous subtypes over the years. EDS is generally characterized by hyperextensible skin, hypermobile joints, and tissue fragility. According to the 2017 International Classification of EDS, 13 subtypes of EDS have been recognized. The majority of genes involved in EDS are either collagen-encoding genes or genes encoding collagen-modifying enzymes. Orthopedic surgeons most commonly encounter patients with the hypermobile type EDS (hEDS), who present with signs and symptoms of hypermobility and/or instability in one or more joints. Patients with joint hypermobility syndrome (JHS) might also present with similar symptomatology. This article will focus on the surgical management of patients with knee or shoulder abnormalities related to hEDS/JHS.
Purpose The purpose of this study was to systematically review the outcomes of arthroscopic management of meniscal cysts and to compare the results across the reported surgical techniques. Methods Following the PRISMA methodology, 3 databases (PubMed, Scopus and Web of Science) were searched from inception to June 2021 for randomized controlled trials (RCTs) and observational studies reporting outcomes on patients with meniscal cysts who underwent arthroscopic surgery. The Mixed Methods Appraisal Tool (MMAT) was used to evaluate the study quality. Results Eighteen studies examining 753 patients (761 meniscal cysts; 92.5% in the lateral meniscus) were included. Overall, 486/736 (66.0%) patients underwent purely arthroscopic decompression, 174/736 (23.6%) received arthroscopic excision, 58/736 (7.9%) received arthroscopy assisted percutaneous drainage, and 18/736 (2.4%) received a combined procedure. The recurrence rate for meniscal cysts was 7.1% across all arthroscopic procedures; 8.3%, 3.4%, and 0% for arthroscopic decompression, arthroscopic excision, and arthroscopy assisted percutaneous drainage, respectively. A total of 79.3% of patients returned to the same level of sport and 85.7% had resolution or minimal knee symptoms after arthroscopic surgery for meniscal cysts. Patient perception of surgical outcomes after any type of arthroscopic surgery for meniscal cysts was reported by 5 studies, with 189/203 (93.1%) reporting satisfaction with their surgical procedure. Conclusion Based on current evidence, arthroscopic management of meniscal cysts yields satisfactory patient outcomes, low cyst recurrence rates and high return to sport rates regardless of the surgical technique. Rates of cyst recurrence were relatively higher with arthroscopic decompression versus excision and percutaneous drainage; however, prospective studies using modern surgical techniques are necessary to better evaluate the surgical outcomes and to compare those with nonoperative modalities, given that a significant proportion of the included articles in this review were relatively outdated. Level of Evidence Systematic review of level II and IV studies.
Objectives: NCAA Division I beach volleyball is a recently introduced sport that has been played for 3 seasons to date. Since the introduction of this new level of athletic participation for women’s’ beach volleyball, no study has been performed to compare the injury patterns between court and sand volleyball playing surfaces. The goal of this study is to compare the injury patterns and incidence in women’s collegiate court and beach volleyball in order to aid trainers, coaches and medical staff in effectively preparing and treating these collegiate athletes. Methods: A 3 year, retrospective review of all training room injury reports were analyzed for both beach and court volleyball from the 2015 through 2017 seasons. Non-athletic injuries or illness were excluded from analysis. Standardized injury rates for beach and court surfaces were calculated by normalizing the total number of injuries by the number of athletes and sets played. To compare the injury patterns among court versus beach volleyball players, injuries were categorized into one of six body regions (abdomen, lower extremity, upper extremity, thorax, head, and back). The proportion of injuries to each of these regions by playing surface was then calculated to compare injury patterns by playing surface. Chi-squared test and odds ratios were used to compare injury rates. Results: Between 2015 and 2017, 90 court volleyball injuries were recorded, while 49 beach volleyball injuries were recorded in the same time period. Court volleyball players had nearly quadruple the injury rate when compared to beach volleyball players, 0.039 and 0.010 injuries per athlete-set respectively (OR 4.05, 95%CI 2.85-5.76, p<0.0001). Court volleyball players suffered a higher proportion of lower extremity injuries when compared to beach volleyball players (51.5% vs. 12.8% respectively, p=0.004), and beach volleyball players suffered a significantly higher proportion of back injuries when compared to court volleyball players, (23.4% vs. 7.8% respectively, p=0.010). Conclusion: The data suggests a significantly higher incidence of injury for court volleyball players when normalized for gameplay exposure. There were, also significant differences in injury patterns with court volleyball players having a higher proportion of lower extremity injuries and beach volleyball having a higher proportion of back injuries. Recognizing these differences can aid in the establishment of preventative strength and conditioning programs as well as post training treatment protocols for these athletes which may increase both the individuals as well as the teams overall competitive success.
