A prospective study of joint function and the quality of life of patients undergoing total joint replacement
1Post-Baccalaureate Program in Nursing, College of Nursing, Taipei Medical University, Taipei, Taiwan.
Aims:
To investigate joint functioning and the quality of life (QOL) before and after total knee and total hip replacement and the factors that influence the QOL.
Methods:
A longitudinal study was conducted between August 2015 and January 2017. A questionnaire composed of the EQ-5D, Oxford Hip Score, and Oxford Knee Score was used to collect data before surgery and 6 weeks, 3 months, and 6 months after surgery.
Results:
A repeated-measures analysis of variance revealed significant differences in the EQ-5D utility index between the preoperative and all 3 postoperative periods (F = 124.195, P < .05). There were significant differences in knee functioning (F = 133.859, P < .05) and hip functioning (F = 34.717, P < .05) between the preoperative and all 3 postoperative periods. The EQ-5D utility index was significantly higher among patients undergoing total knee replacement than those undergoing total hip replacement (F = 15.490, P < .05) and higher among female than male patients (F = 7.613, P < .05). A positive correlation between the QOL and the perceived convenience of living at home was observed (P < .05).
Conclusions:
The findings are expected to inform patient education for patients undergoing arthroplasty surgery.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
Joints
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
Fibrous Joints Are Immovable

Method of Joints
Since plane truss members are in the same plane, each joint is subjected to a coplanar and concurrent force system. To apply the method of joints, the first step is to...
