<p><b>INTRODUCTION: </b>Anterior knee pain is a major problem following Bone-patellar-tendon-bone graft (BPTB) use in anterior cruciate ligament (ACL) reconstruction. We hypothesized that filling the donor defect sites with bone-graft substitute would reduce the anterior knee symptoms in ACL reconstruction surgeries.</p>

<p><b>MATERIAL AND METHODS: </b>Patients operated for ACL-deficient knee between March 2012 and August 2013 using BPTB graft were divided into two treatment groups. The patellar and tibial donor-site bony defects were filled-up with Hydroxyapatite-Bioglass (HAP:BG) blocks in the study group (n&nbsp;=&nbsp;15) and no filler was used in the control group (n&nbsp;=&nbsp;16). At 2 years, the clinical improvement was assessed using International Knee Documentation Committee (IKDC) score and donor-site morbidity was assessed by questionnaires and specific tests related to anterior knee pain symptoms.</p>

<p><b>RESULTS: </b>Donor-site tenderness was present in 40% patients in the study group and 37.5% patients in the control group (p&nbsp;=&nbsp;0.59). Pain upon kneeling was present in 33.3% patients in the study group and 37.5% patients in the control group (p&nbsp;=&nbsp;0.55). Walking in kneeling position elicited pain in 40% patients in the study group and 43.8% in the control group (p&nbsp;=&nbsp;0.56). The mean visual analogue score for knee pain was 3.0 in the study group and 3.13 in the control group, with no statistically significant difference (p&nbsp;=&nbsp;0.68). Unlike control group, where a persistent bony depression defect was observed at donor sites, no such defects were observed in the study group.</p>

<p><b>CONCLUSION: </b>Filling the defects of donor sites with HAP:BG blocks do not reduce the anterior knee symptoms in patients with ACL reconstruction using autogenous BPTB graft.</p>

J.b Thilak, Panakkal, J. Jab, Kim, T. - Ya, Goodman, S. Mc, Lee, S. - Sa, and Salvati, E. Ac, “Risk Factors of Heterotopic Ossification Following Total Hip Arthroplasty in Patients With Ankylosing Spondylitis”, Journal of Arthroplasty, 2015.[Abstract]

This study was to identify the risk factors of heterotopic ossification (HO) after total hip arthroplasty (THA) in ankylosing spondylitis. We analyzed 47 hips (24 patients) with ankylosing spondylitis that underwent primary THA. The incidence of HO was 14.9%. The risk factors were divided into modifiable and nonmodifiable factors. Female gender (P = 0.008), preoperative ankylosed hip (P . <. 0.001), occurrence of HO in previous surgery (P = 0.036) were nonmodifiable risk factors which increased the prevalence of HO. Of the various modifiable risk factors, elevated preoperative ESR (P = 0.007), elevated preoperative CRP (P = 0.004) and prolonged duration of surgery (P = 0.014) were associated with increased occurrence of HO. Perioperative medical intervention to reduce inflammation (ESR and CRP) may help to decrease HO. © 2015.

Salmonellosis is a common infection in systemic lupus erythematosus patients. The present study reports on two such cases of Salmonella typhimurium septic arthritis among the 102 patients seen during a four-year period. More »»
