Summary
Rheumatoid arthritis frequently affects the knee. Surgical options like arthroscopic synovectomy and total knee replacement offer excellent long-term outcomes, improving function and reducing pain for most patients.
Area of Science:
- Orthopedics
- Rheumatology
- Surgical Innovation
Background:
- Polyarticular rheumatoid arthritis commonly impacts the knee joint.
- Surgical strategies for knee involvement are dictated by articular cartilage status and synovitis severity.
Purpose of the Study:
- To review surgical management options for rheumatoid arthritis affecting the knee.
- To evaluate the efficacy and outcomes of arthroscopic synovectomy and total knee replacement in rheumatoid arthritis patients.
Main Methods:
- Review of surgical techniques including arthroscopic synovectomy for cartilage preservation in severe synovitis.
- Analysis of total knee replacement complexity in rheumatoid arthritis due to bone and soft-tissue compromise.
- Assessment of complication rates, particularly infection, associated with knee arthroplasty.
Main Results:
- Arthroscopic synovectomy is indicated for persistent synovitis when cartilage can be spared.
- Total knee replacement in rheumatoid arthritis presents surgical challenges and increased complication risks.
- Long-term knee arthroplasty results in rheumatoid arthritis are generally excellent, significantly enhancing function and alleviating pain.
Conclusions:
- Surgical intervention for rheumatoid arthritis of the knee requires careful consideration of joint condition.
- Both arthroscopic synovectomy and total knee replacement can yield substantial benefits in function and pain relief.
- Despite complexities, knee arthroplasty demonstrates high success rates for long-term management of rheumatoid arthritis.

Bones of the Lower Limb: Femur and Patella
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 neck...
Knee Joint
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 group...

Ankle Joint
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...
