RESUMEN
Surgery failure rates average 20% following bucket-handle meniscal tears (BHMT) repairs in the literature. Achieving the healing of BHMT is difficult, how much more in revision cases. Some authors have reported higher failure rates especially in the early postoperative period and in younger patients. Multiple techniques and augmentations to enhance biologic healing and reduce failure rate have been described. We describe an arthroscopic technique for successfully revising a failed BHMT repair using the technique of percutaneously releasing the posterior fibers of the medial collateral ligament to provide adequate space for arthroscopy, refreshing of the torn surfaces, bed trephination before reduction and repair. We concluded that a combined double-level inside out vertical sutures with horizontal reinforcement and all-inside technique using fast fix give anatomic reduction, stable fixation, surface contact, and increased potential for biologic healing in failed BHMT repairs. Coupled with adequate rehabilitation programs, this technique has reduced the failure rate in revision cases and enhances early return to sport.
RESUMEN
The HLA class I and class II alleles in 67 patients with type I psoriasis vulgaris, 23 patients with type II psoriasis vulgaris and 140 healthy individuals were analyzed. The frequencies of HLA-A2, -B46, -B57 and DQB1*0303 were significantly increased in type I psoriasis compared to the controls (Pc<0.05). Molecular analysis of HLA-A2 alleles showed an increase in HLA-A*0207 and a decrease in HLA-A*0203 in type I psoriasis. HLA-DQB1*0301 was significantly decreased in type I psoriasis compared to the normal controls (Pc<0.05). No association of any alleles with type II psoriasis was observed. This data demonstrated two susceptible haplotypes: HLA-A1-B57-DRB1*0701-DQA1*0201-DQB1*0303 (AH57.1) and HLA-A2-B46-DRB1*0901-DQA1*0301-DQB1*0303 (AH46.1) for type I psoriasis in the Thai population. Besides, the haplotype AH46.1 was also associated with type II psoriasis.
