RESUMO
BACKGROUND: Chronic Exertional Compartment Syndrome (CECS) of the forearm is characterized by an increase of the pressure in the forearm compartments during repeated activities. Its diagnosis is challenging because of the lack of clearly established diagnostic criteria. PURPOSE: We aimed to provide a comprehensive description of the diagnostic methods used for CECS of the forearm, to assess if a more effective diagnosis strategy could be identified. METHODS: We used PubMed, Google Scholar, Cochrane Library and Science Direct databases to search articles. We carried out multiple searches using the mesh terms ("Chronic Exertional Compartment Syndrome" OR "Chronic compartment syndrome" OR "Exertional compartment") AND ("forearm" OR "upper limb"). Inclusion criteria were prospective or retrospective studies on CECS of the forearm including case reports. We used PRISMA guidelines. The included studies were critically appraised using GRADE approach. RESULTS: A total of 625 articles were screened and 33 studies were included. It represented 590 patients (505 men and 85 women), with a mean age of 26.6 years old. Among them, 282 competed at an elite level. Motorcycling and motocross were the most frequent sports (66%). Six diagnostic methods were employed. Intra-compartmental pressure (ICP) measurement was the most frequently used method in 26 studies. Magnetic resonance imaging was performed in 9 studies, while electromyography was employed in only 2 studies. One study reported the measurement of grip strength using a manual dynamometer, one study compared forearm circumference before and after effort, and one used myotonometry. Various exercise protocols were observed. Stress-testing using a hand-grip was the most common protocol in 14 studies. Exercise duration varied from 2 min to 60 min. CONCLUSION: Existing data do not provide sufficient evidence to favor an alternative diagnostic method over ICP measurements that should be used cautiously given the absence of formal validation. Non-invasive methods might be easier to use, but should be subjected to further research. LEVEL OF EVIDENCE: III.
RESUMO
Background: After the rupture of the anterior cruciate ligament (ACL), surgery is proposed in the case of knee instability or for athletes who want to return to a pivotal and/or contact sport. The current trend is to extend physiotherapy sessions until a patient's return to sport. We aimed to assess the interest in prolonging the physiotherapy sessions up to 4 postoperative months to restore muscle knee strength and function. Methods: From a historical cohort, 470 patients (24.3 ± 8.7 years) were included; 312 (66%) were males. They all had undergone a primary ACL reconstruction with a hamstring procedure. The number of physiotherapy sessions was established at 4 postoperative months. The main study parameters to assess the benefit of prolonged physiotherapy were the isokinetic limb symmetry index (LSI) for the quadriceps and the hamstrings as well as the Lysholm score. Results: At 4 postoperative months, 148 patients (31.4%) still had physiotherapy sessions. This group had performed 49 ± 14 physiotherapy sessions at the time of evaluation compared to 33 ± 9 sessions performed by the group that stopped physiotherapy at 3 months post-ACL reconstruction. The isokinetic knee LSI and the Lysholm score were not different between the two groups. Continued physiotherapy sessions were associated with female gender, previous high sport level, meniscal repair, lateral tenodesis and outpatient rehabilitation at the beginning of the rehabilitation management, while knee pain complications were not associated. Conclusions: No significant correlation was found between the number of physiotherapy sessions and the knee strength LSI or the Lysholm score. Prolonging patient physiotherapy sessions after 3 months post-ACL reconstruction seems ineffective in improving knee strength recovery and function.
