Double and Single Bundle in Athletes: A Comparison in Medium and Long-Term Rates to Return to Sport and Re-Injury.

Objectives: Compare, retrospectively, the medium- and long-term of return to sport rates and re-injury of the anterior cruciate ligament (ACL) in patients submitted to single-bundle (SB) compared to double-bundle (DB) technique reconstruction. Methods: Athletes operated by SB or DB ACL reconstruction, with at least five years of follow-up at a single center, were included. The following data were collected: demographic data; competitive sports practice before the injury; previous surgery; injury/surgery to the contralateral knee; return to sports and level of the return; re-injury (time of the re-injury after the first surgery; mechanism of trauma for the re-injury; necessity of operative treatment); signs and complaints related to the knee the last clinical consultation. Results: Seventy-six athletes (27 SB and 49 DB) were included. The return to sport rate (98%) was the same for both groups, and the return to the previous level rate showed an improvement in the DB group but without statistical significance (63% vs. 79%; P = 0.173). However, other outcomes showed higher results for the DB group: lower re-injury rate throughout the follow-up period (41% vs. 18%; P = 0.034) and during the first year of follow-up (22% vs. 4%; P = 0.021), and less stiffness (0% vs. 22%, P = 0.001). While in primary reconstruction cases, there was not a higher re-injury rate using SB (P = 0.744), in the revision cases, SB was correlated with more re-injuries than DB (P = 0.002). Conclusion: The overall re-injury in the medium- and long-term and the return to practice sports at the same level as before surgery in athletes submitted to DB reconstruction were slightly better than those submitted to SB reconstruction, especially in the cases that were asecond time lesion ( revisioned knees).

Return to Sport and Re-Injury Rate after Double-Bundle Anterior Cruciate Ligament Reconstruction with at least Five Years of Follow-Up.

BACKGROUND: This study retrospectively evaluated the medium- and long-term results of patients submitted to double-bundle (DB) anterior cruciate ligament (ACL) reconstruction. METHODS: A retrospective study of case series at a single center. Cases submitted to isolated ACL reconstruction with at least five years of follow-up were included. The following data were collected: demographic data; practice of competitive sport before the injury; previous surgery; injury/surgery in the contralateral knee; return to the practices of sports and level; re-injury (postoperative time; mechanism; need for surgery); and symptoms at the last clinical follow-up visit. Descriptive and sub-group analyses were performed. RESULTS: Sixty-nine patients were included; 52 men (75%), 49 athletes (71%), 47 (68%) with primary injury, mean age of 30 years (SD 10). The patients were followed up for an average of 8.7 years (minimum 5, maximum 11.8) after surgery. After the reconstruction, 67 (97%) returned to the sport; 75% at the same level as before the injury. Ten patients (14%) suffered re-injury after an average of 32 months (between 9 and 50 months). Regarding the outcome of re-injury, no statistically significant differences were found between subgroups of athletes vs non-athletes or primary injury vs revision surgery, despite a significant tendency towards increased re-injury levels in athletes. However, this tendency was not statistically significant. CONCLUSION: In our series of patients operated on with the double-bundle technique and with a long follow-up time, 14% presented re-injury, with no differences between primary and revision cases, and with a trend towards higher re-injury levels among the athletes in relation to the non-athletes. The rate of return to sport was satisfactory, with 97%, of which 75% were playing at the same level as before the injury.

Phase angle and World Health Organization criteria for the assessment of nutritional status in children with osteogenesis imperfecta / Ângulo de fase e critérios da Organização Mundial de Saúde na avaliação do estado nutricional em crianças com osteogênese imperfeita

Abstract Objective: To compare the phase angle of patients with osteogenesis imperfecta treated at a tertiary university hospital with patients in a control group of healthy children, and to assess the nutritional status of these patients through the body mass index proposed by the World Health Organization. Methods: Cross-sectional study carried out in a university hospital that included seven patients with osteogenesis imperfecta and a control group of 17 healthy children of the same gender and age. Weight and height were measured and bioelectrical impedance was performed. Subsequently, the phase angle was calculated based on resistance and reactance values. Results: The phase angle of the group of children with osteogenesis imperfecta was significantly lower than that of the control group (p<0.05). The body mass index criterion for age of the World Health Organization showed no difference between groups. Conclusions: Children with osteogenesis imperfecta have a nutritional risk detected by the phase angle, which is a useful tool for nutritional screening. The calculation result could help in the diet therapy of patients with osteogenesis imperfecta.

Resumo Objetivo: Comparar o ângulo de fase de pacientes com osteogênese imperfeita atendidos em um hospital universitário terciário com pacientes de um grupo controle de crianças saudáveis, bem como avaliar o estado nutricional desses pacientes pelo índice de massa corporal proposto pela Organização Mundial de Saúde. Métodos: Estudo transversal feito em hospital universitário que incluiu sete pacientes com osteogênese imperfeita e um grupo controle composto por 17 crianças saudáveis de mesmo sexo e idade. Foram aferidos peso e estatura e foi feito o exame de impedância bioelétrica. Posteriormente, o ângulo de fase foi calculado a partir dos valores de resistência e reactância. Resultados: O ângulo de fase do grupo de crianças com osteogênese imperfeita foi significativamente menor do que o do grupo controle (p<0,05). O critério de índice de massa corporal por idade da Organização Mundial de Saúde não mostrou diferença entre os grupos. Conclusões: Crianças com osteogênese imperfeita têm um risco nutricional detectado pelo ângulo de fase, é uma ferramenta útil para triagem nutricional. O resultado do cálculo poderia auxiliar a dietoterapia de pacientes com osteogênese imperfeita.
