Approximately 80% of Japanese osteoarthritic patients fall out of the safety range in restricted kinematically-aligned total knee arthroplasty in an analysis of preoperative long-leg radiograms

BackgroundRestricted kinematically-aligned total knee arthroplasty (KA-TKA) is a reasonable modification to avoid the alignment outlier that may cause implant failure. However, despite a noted high incidence of constitutional varus in Japanese individuals, there has been no investigation into how many knees require the restriction in restricted KA-TKA (RKA-TKA) among Japanese patients. Therefore, we conducted a study using preoperative long-leg radiograms.MethodsWe studied long-leg radiographs of 228 knees in 114 consecutive patients. The numbers of knees within the safety range and their corrective osteotomy angle in the restriction algorithms advocated by Almaawi et al. (2017) and MacDessi et al. (2020) were evaluated.ResultsAccording to the algorithms used by Almaawi et al. and MacDessi et al., out of 228 knees, 46 (20%) and 39 (17%) fell within the safety range, respectively. The mean correction angles of the hip-knee-ankle angle, lateral distal femoral angle and medial proximal tibial angle were 2.8 ± 3.4°, 0.4 ± 1.4° and 2.4 ± 2.8° in the algorithm used by Almaawi et al., while they were −4.9 ± 4.7°, 1.1 ± 2.5° and −6.0 ± 3.4° in the algorithm used by MacDessi et al. Most of the knees needed to be restricted in order to perform RKA-TKA, regardless of the algorithm used.ConclusionsBased on a preoperative analysis of long-leg radiograms in a Japanese population, most knees fall out of the safety range in RKA-TKA. Surgeons must consider whether to allow component outlier or to perform corrective osteotomy that likely requires soft tissue release.     

Pyogenic granuloma-like reaction in the necrotic, vessels-deprived femoral head of the rat

Osteonecrosis of the femoral head was produced in rats by cutting the ligamentum teres and incising the cervical periosteum. As of the second postoperative week, fibrous tissue pervaded the necrotic epiphyses, macrophages and osteoclasts removed the debris, osteoblasts deposited lamellar-fibred and woven-fibred intramembranous bone, and remodeling began. In 16% of the rats killed during the 2nd postoperative week, the epiphyses contained big fragments of necrotic bone enclosed by densely packed, capillary-sized vessels. Ingrowth of this hypervascularized, pyogenic granuloma-like tissue is presumably due to the presence of excessive growth factors, reflecting an exaggerated pathophysiological reaction within the framework of organization of the necrotic epiphyses.     

逆行带锁髓内钉治疗股骨远端骨折的应用解剖

目的:为带锁髓内钉治疗股骨远端骨折提供形态学基础。方法:①选用30例成人干燥股骨测量股骨内外侧髁、内外上髁、髁间窝有关数据进行统计分析。②20侧下肢标本解剖观测膝降动脉及隐神经髌下支的分支、分支等及两者的关系。结果:髁间窝呈U型占35%,V型占65%,此窝最宽处横径:左侧(1.98±0.36)cm, 右侧(2.06±0.29) cm;内侧髁后关节面宽,左侧(2.21±0.23) cm,右侧(2.34±0.29) cm;内、外上髁的距离,左侧(7.30±0.60)cm,右侧(7.43±0.57)cm。膝降动脉髌下支和隐神经髌下支呈紧密的伴行关系。隐神经在缝匠肌中下1/3交界点穿出,有上、下两支分布到膝关节前外侧皮肤。结论:术中注意这些解剖位置特点,避免损伤神经和血管,减少手术出血,防止并发症。
