Forty young athletes with the indication of ACL reconstructio

\n\nForty young athletes with the indication of ACL reconstruction with patellar tendon grafts were randomly

assigned to group A (n = 20 patients, control group) or group B (n = 20 patients, PRP group). The autologous PRP gel was applied to both the patellar and tendon bone plug harvest site and stabilized by the peritenon suture. At 12-month follow-up, all patients underwent clinical examination and VAS and VISA questionnaires, respectively, evaluating the average daily pain of the knee and the pain NVP-AUY922 during particular activities involving the knee, were filled. MRI at the same time point was also performed.\n\nVISA scores were significantly higher in the patients treated with PRP (84.5 +/- A 11.8 and 97.8 +/- A 2.5 for group A and for group B; P = 0.041), whereas no significant

difference in postoperative VAS scores between the two groups was observed (1 +/- A 1.4 and 0.6 +/- A 0.9 for group A and group B, n.s.). In 85% of PRP group patients, the tibial and patellar bone defect was satisfactorily filled by new bony tissue (> 70% of bone gap filled), whereas this percentage was just of HSP990 order 60% in control group patients, but this difference was not statistically significant.\n\nThe study shows the usefulness of PRP in reducing subjective pain at the donor-site level after ACL reconstruction with BPTB. However, this approach deserves further investigations to confirm PRP efficacy and to elucidate its mechanism of action.\n\nProspective randomized controlled study, buy SBC-115076 Level I.”
“This study compared reactive agility between higher-standard (n = 14) and lower-standard

(n = 14) Australian footballers using a reactive agility test incorporating a life-size video image of another player changing direction, including and excluding a feint. Mean agility time in the feint trials was 34% (509+/-243 ms; p<0.001; effect size 3.06) longer than non-feint trials. In higher-standard players, agility time was shorter than for lower-standard players in both feint (114+/-140 ms; p = 0.18; effect size 0.52; likely beneficial) and non-feint (32+/-44 ms; p = 0.22; effect size 0.47; possibly beneficial) trials. Additionally, the inclusion of a feint resulted in movement time increasing over three times more in the lower-standard group (197+/-91 ms; p = 0.001; effect size 1.07; almost certainly detrimental) than the higher-standard group (62+/-86 ms; p = 0.23; effect size 0.66; likely detrimental). There were weak correlations between the feint and non-feint trials (r = -0.13-0.14; p>0.05), suggesting that reactive agility involving a feint is a unique skill.
