Joint Replacement
Joint replacement surgery involves the removal of a damaged joint and the insertion of
a new one. Joints, where two or more bones meet (such as the knee, hip, and
shoulder), are typically the focus of this procedure, which is commonly performed by
an orthopaedic surgeon. In some cases, the surgeon may opt to address only the
damaged portions rather than replacing the entire joint.
The purpose of joint replacement is to alleviate pain and improve mobility and overall
well-being. Hips and knees are the joints most frequently replaced, but the procedure
can also extend to other areas like shoulders, fingers, ankles, and elbows.
What Is a New Joint Like?
A prosthesis, known as a new joint, can comprise plastic, metal, or ceramic
components and can either be affixed with or without cement, allowing the bone to
integrate with it. The cemented joint is preferred for older individuals with limited
mobility and those with fragile bones as the cement secures the new joint to the bone.
Conversely, an uncemented joint is typically suggested for younger, more active
individuals and those with strong bone density. However, healing may take longer as
the bone requires additional time to grow and bond with the joint.
What Happens After Surgery?
Post knee or hip surgery, a hospital stay is typical, possibly followed by weeks in
intermediate care if you're older or have disabilities. The duration in the hospital is
determined by your medical team.
After the procedure, walking with aid begins soon, initially with discomfort due to
weakened muscles and healing. Pain relief medication helps, and the discomfort
typically resolves in weeks or months.
Physical therapy starts promptly to strengthen muscles and restore joint movement.
Shoulder joint replacement allows immediate exercises. Therapists guide gentle
motions and demonstrate equipment use before discharge.
