Although glucosamine is commonly consumed by athletes, its effectiveness in sports injuries is still under debate. We aimed to investigate the effects of glucosamine to the rehabilitation outcomes of anterior cruciate ligament (ACL) reconstructed athletes. Glucosamine-sulfate (1000 mg daily, for 8 weeks) was administered to half of the cohort of 30 male athletes, the other half used a placebo. Both groups received the same rehabilitation protocol. Knee pain and functions were evaluated by a visual analogue scale (VAS), International Knee Documentation Committee (IKDC) and Lysholm scores before and after oral administration. Additionally, an isokinetic test was performed after the administration period. The scores revealed significant improvements in both groups after 8 weeks, but no significant difference was detected between groups in any of the parameters. Glucosamine supplementation did not improve the rehabilitation outcomes of athletes after ACL reconstruction. This is the first study investigating this topic. Further studies will help to obtain clear evidence about glucosamine efficacy on ACL injured or ACL reconstructed athletes.
KOSE, O.; ERASLAN, A.; ERGUN, A.; EGERCI, O. F. & ERCAN, E. C.Prevalence of bipartite patella in Turkish population; analysis of bilateral knee radiographs in 897 subjects. Int. J. Morphol., 33(3):1108-1113, 2015.
SUMMARY:Bipartite patella is a normal anatomic variant of patella. There are various data about the prevalence of bipartite patella in the literature. The aim of this study was to investigate its prevalence, type distribution and sex predilection in Turkish population. Bilateral knee radiographs were retrospectively reviewed of 897 consecutive adult patients. Cases with bipartite patella were categorized according to the Oohashi classification. Medical records were examined in order to differentiate symptomatic and asymptomatic bipartite patellae. We contacted symptomatic patients by telephone to learn continuity of knee pain. We identified 11 cases (7 male, 4 female) of bipartite patella among the 283 male and 614 female patients. No bilateral cases were identified. The prevalence of bipartite patella was 1.22% overall, 2.47% in males, and 0.65% in females. The most common type was superolateral bipartite patella as seen in 9 patients (81.8%). One subject had lateral bipartite and one subject had superolateral tripartite patella. Painful bipartite patella was found in only 2 patients (18%). One of them had continuing symptoms even after 12 months. In conclusion, we found that the prevalence of bipartite patella in Turkish population was approximately 1%. Both inclusion of only adult (skeletally mature) subjects and assessment with bilateral imaging increased the reliability of this value. In accordance with the literature, bipartite patella was found significantly more frequent in males and mostly in superolateral type. More studies are needed in order to obtain the prevalence, type and sex distribution of bipartite patella in different populations.
Purpose:Our aims were to determine the feasibility of diffusion-weighted magnetic resonance imaging (DWI) in the detection of bone marrow edema (BME) and explore the apparent diffusion coefficient (ADC) alterations in patients with osteitis pubis (OP).Materials and Methods:42 consecutive patients clinically suspected to have athletic pubalgia and 31 control subjects were enrolled in the study. All subjects underwent diagnostic focused magnetic resonance imaging (MRI) and DWI at b values of 0 and 600 s/mm2. Two radiologists reviewed the images for the presence of active OP. The presence of subchondral BME and contrast enhancement were considered to indicate active OP. ADC values were measured from public bodies of both groups. DWI results were correlated with routine MRI findings. Receiver-operating-characteristic curves were formed. Cut-off values for ADC, sensitivity and specificity values were measured.Results:36/42 (85%) of the cases had BME/enhancement on routine MRIs and identified as active OP. ADC measurements of the patients were greater than the controls (P < 0.05). For the optimal cut-off values DWI showed sensitivity and specificity values of 97.3%, and 90.3%, for the right, and 97.1%, and 96.7% for the left side, respectively (Area under the curve 0.965 and 0.973). Intra-and inter-rater reliability for readers were substantial-perfect for all sessions.Conclusion:DWI is fast, accurate, and highly reproducible technique for the detection of BME in patients with active OP. It allows distinct bone marrow contrast without the use of gadolinium contrast, increases visual perception of active lesions, gives objective information by quantifying the diffusion coefficients, thus increase diagnostic confidence. We suggest the use of DWI as a cost-effective adjunctive tool for the diagnosis of active OP particularly in early cases and inconclusive diagnostic MRI. Future studies are necessary to determine the utility of DWI to evaluate severity of the disease and treatment response before returning athletes to play.
