虽然跟腱(AT)断裂(ATR)的手术(OM)与非手术治疗(NOM)的相对益处仍存在争议,很少有研究研究对跳跃和跳跃等高冲击机动的影响。
■这项研究的目的是确定功能性能是否包括强度,跳跃,急性ATR的OM和NOM之间的跳跃结果不同。次要目标是评估AT形态与表现结果之间的关联程度。
■采用单一前瞻性评估的回顾性队列。
■所有患者均在机构二级保健中心接受治疗。在损伤后三周内接受OM或NOM治疗的合格参与者(n=12OM;12NOM)在ATR后至少20个月进行评估。AT长度,用B型超声评估厚度和腓肠肌厚度。等速足底屈肌力量,跳跃测试以及反向移动和掉落跳跃已完成。双向ANOVAS在所有具有单边值的测试中完成,独立t检验用于双侧结果,并完成线性回归以评估归一化AT长度与性能之间的关系。
■患肢AT拉长和增厚(p<0.01),腓肠肌萎缩(p\\<0.01),在20°足底屈曲时,特定角度的足底屈肌扭矩在120°/s时降低(p=0.028)。OM中单腿垂直跳跃较高(p=0.015),跳跃和跳跃测试没有差异。AT长度与足底屈肌扭矩有关,但与跳跃性能无关。
■尽管存在足底弯曲无力,但仍保持了跃点测试性能,腓肠肌萎缩,和在伸长率。这可能是补偿性运动模式的结果。AT长度对足底屈肌强度的解释力有限,尽管这种关系应该进一步评估。
■三级。
UNASSIGNED: While controversy remains as to the relative benefit of operative (OM) versus non-operative management (NOM) of Achilles tendon (AT) ruptures (ATR), few studies have examined the effect on high impact maneuvers such as jumping and hopping.
UNASSIGNED: The purpose of this study was to determine if functional performance including strength, jumping, and hopping outcomes differed between OM and NOM of acute ATR. The secondary objective was to assess the degree of association between AT morphology and performance outcomes.
UNASSIGNED: Retrospective cohort with a single prospective evaluation.
UNASSIGNED: All patients were treated at an institutional secondary care center. Eligible participants (n=12 OM; 12 NOM) who were treated with OM or NOM of ATR within three weeks of injury were evaluated a minimum 20 months following ATR. AT length, thickness and gastrocnemius muscle thickness were assessed with B-mode ultrasound. Isokinetic plantar flexor strength, hop tests and countermovement and drop jumps were completed. Two-way ANOVAS were completed on all tests with unilateral values, independent t-tests were used for bilateral outcomes, and linear regressions were completed to assess the relationship between normalized AT length and performance.
UNASSIGNED: Affected limb AT was elongated and thickened (p\\<0.01), gastrocnemius was atrophied (p\\< 0.01) and angle-specific plantar flexor torque was reduced at 120°/s when measured at 20° plantar flexion (p = 0.028). Single leg drop vertical jump was higher in OM (p = 0.015) with no difference for hop and jump tests. AT length was related to plantar flexor torque but had no relationship with hopping performance.
UNASSIGNED: Hop test performance was maintained despite plantarflexion weakness, gastrocnemius atrophy, and AT elongation. This may be the result of compensatory movement patterns. AT length holds limited explanatory power in plantar flexor strength, although this relationship should be evaluated further.
UNASSIGNED: Level III.
