概括
在前十字带重建后,年轻人的膝盖与软骨缺陷有关,但不恶化骨关节炎. 那些患有的患者最初报告的结果较差,后来疼痛和功能有所改善.
科学领域:
- 整形医学
- 运动医学
- 放射学
背景情况:
- 创伤性膝盖损伤,如前交叉带重建 (ACLR),可能导致长期的结构变化和功能缺陷.
- 在关节运动过程中有触觉或听觉的膝盖是常见的症状,可能表明关节病态.
研究的目的:
- 在ACLR后1年和5年,调查自我报告的膝盖和结构性关节炎特征 (软骨病变,骨质细胞,骨髓病变) 之间的关联.
- 根据ACLR,检查膝盖和自我报告的结果之间的关系,包括疼痛,生活质量和功能.
主要方法:
- 经过ACLR治疗的112名参与者 (41名女性,平均年龄28岁) 在手术后一年报告了膝盖.
- 磁共振成像 (MRI) 评估了1岁和5岁的骨关节炎特征.
- 统计模型 (Poisson回归,一般线性模型) 分析了,结构变化和自我报告结果 (KOOS,IKDC) 之间的关联.
主要成果:
- 自报的膝盖与ACLR后一年的全厚骨骨损伤有显著的相关性 (PR 2. 70).
- 在ACLR后1至5年间,Crepitus与结构性关节炎特征恶化的风险增加无关.
- 一年后,患有的参与者报告疼痛,生活质量和功能更差,但五年后疼痛和功能更好.
结论:
- 在ACLR后的年轻成年人中,自我报告的膝盖与骨缺陷的存在有关.
- 在ACLR治疗后的五年内,膝关节并不能预测骨关节炎结构特征的恶化.
- 虽然膝盖与一年后的较差结果有关,但可能不会阻止长期的功能恢复.

01:23Knee Joint
2.2K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

01:16Bones of the Lower Limb: Femur and Patella
2.9K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

1.8K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
