Arthriscopic joint dehridcment of the osteoarthritic knee is a well-clocumented proceclure to alleviate symptoms and improve. The knee joint function. Debridement operation include joint larvage, synovectomy, ost.eophyte rcmoval. Partial menisectomy, notchplasty, multiple dri]ling and abrasion arthroplasty. Multiple drilling procedure and ahrasion arthroplasty give vascular access to the eburnated subchondral hone for regenevation of fibrocartilage. But in practice, the drilling is a technically deimanding procedure and sometinne, iinpossihle to be pierformed in a limited area of the knee joint. Control of abrasion depth in ;lhr;)sion .trthvo)pl;istv is stiil not an easy work. We have successfully made multiple uniform drillings an cortical abrasion on the sclerotic subchondral hone hy using the Holmium: Yag laser. Laser-Assistd Arthroscopic Debridement (LAAD) for the osteoarthritic knee joint vwhich is easy to perform, thus time saving procedure, gives less iatrogenic injury to otherwise normal tissue and allow the LAMP(Laser Abrasion Multiple Puncturing)for cartilage regeneration,a new trial ot cartilage enhancement.

The purpose of this study is to evaluate anteroposterior laxity by use of the KT-2000 arthrometer after arthroscopic ACL reconstruction and to compare allografts with autografts. 83 patients undergoing arthroscopic ACL reconstruction was studied prospectively. The subjects were divided into 3 groups according to the type of graft:autograft bone pateller tendon bone(N=33) ;freeze dried allograft BPTB(N=33) ;cryopreserved allograft BPTB(N=17). Manual maximum displacement tests by KT-2000 were performed to measure anterior tibial displacement preperatively, at 6 weeks and at 12 weeks. No difference was seen statistically in age and sex among 3 groups(p<0.05). The average side to side KT-2000 differences at the manual maximum test were 6.65mm(autograft BPTB), 6.09mm(freeze dried allograft BPTB), and 6.36mm (cryopreserved allograft BPTB) preoperatively; 2.47mm (autograft BPTB), 3.02mm (freeze dried allograft BPTB), and 2.68mm(cryopreserved allograft BPTB) at 12 weeks. Results revealed no significant difference among 3 groups(p.0.05). We conclude that the allograft is comparable to autograft as a primary choice in reconstruction of ACL using BPTB. This is a preliminary results of a 12 weeks follow-up study, therefore, long-term outcome should be investigated in future studies.
