Artificial joint


Hello Doctor: My mother had a joint replacement over three months ago, and she is still limping while walking.
There is some swelling, and her leg feels weak.
When she wakes up, she cannot walk immediately and has to wait a bit before she can start walking.
We are unsure of the reason, so I would like to ask for your advice, Doctor.

Is it a total knee replacement surgery? Typically, the recovery period for this type of surgery is within three months.
If pain persists beyond three months, it is essential to investigate the cause.
If there is redness, swelling, or heat at the incision site, an infection should be ruled out.
Additionally, it is important to check whether the prosthetic joint has dislocated or loosened, and to assess for any instability.
In summary, further examination is necessary, and you can either return to the original surgeon or consult another physician for evaluation.

After joint replacement surgery, particularly hip or knee replacements, it is not uncommon for patients to experience a range of post-operative challenges. Your mother’s symptoms, such as limping, swelling, weakness in the leg, and difficulty walking immediately after waking up, can be attributed to several factors that are important to understand.

Firstly, it is essential to recognize that the recovery process after joint replacement surgery can be gradual and varies significantly from person to person. Factors such as age, overall health, pre-existing conditions, and adherence to rehabilitation protocols can all influence recovery outcomes. In your mother’s case, three months post-surgery is still within the early stages of recovery, and some discomfort and functional limitations are expected.

1. Limping and Weakness:
Limping can be a result of several factors, including pain, muscle weakness, or improper gait mechanics. After surgery, the muscles surrounding the joint may be weak due to disuse or atrophy prior to the procedure. Physical therapy is crucial in this phase to strengthen these muscles and improve gait mechanics. If your mother has not been consistently participating in rehabilitation exercises, this could contribute to her ongoing limp and weakness.

2. Swelling:
Swelling is a common post-operative symptom and can persist for several weeks or even months after surgery. It is often due to inflammation from the surgical trauma and the body’s healing response. Elevating the leg, applying ice, and engaging in gentle movement can help reduce swelling. If the swelling is significant or accompanied by increased pain, it may warrant further evaluation to rule out complications such as infection or blood clots.

3. Delayed Mobility:
The need to wait before walking after waking up can be related to several factors, including pain management, muscle stiffness, or even the effects of anesthesia. After surgery, patients often experience stiffness in the joint, which can make immediate movement difficult. Encouraging your mother to engage in gentle stretching and mobility exercises, as advised by her physical therapist, can help improve her range of motion and facilitate easier movement upon waking.

4. Pain Management:
Effective pain management is crucial for recovery. If your mother is experiencing significant pain, it could inhibit her ability to engage in physical therapy and daily activities, leading to a cycle of decreased mobility and increased discomfort. It is important to communicate with her healthcare provider about her pain levels and explore options for better pain control, which may include medications or alternative therapies.

5. Follow-Up Care:
Regular follow-up appointments with her orthopedic surgeon are essential to monitor her recovery progress. During these visits, the surgeon can assess her joint function, address any concerns about swelling or pain, and adjust her rehabilitation plan as needed. If her symptoms persist or worsen, further imaging studies, such as X-rays or MRIs, may be necessary to evaluate the integrity of the joint replacement and surrounding structures.

In conclusion, while your mother’s symptoms are concerning, they are not uncommon in the post-operative period following joint replacement surgery. It is crucial to maintain open communication with her healthcare team, adhere to prescribed rehabilitation protocols, and address any new or worsening symptoms promptly. With time, patience, and appropriate care, many patients experience significant improvements in mobility and quality of life following joint replacement surgery.
