Knee Replacement Aftermath: Understanding Exercises, Causes, and Additional Factors
Hip Pain After Knee Replacement Surgery: Understanding the Causes and Management
Knee replacement surgery is a common procedure, replacing a damaged joint with a prosthetic one to alleviate pain and improve mobility. However, a surprising finding is that hip pain can occur after this surgery, often due to factors such as altered gait mechanics, muscular weakness or imbalance, nerve irritation, and referred pain from the knee or surrounding structures [1][4].
Causes of Hip Pain After Knee Replacement
The postoperative changes in biomechanics and muscle function can put extra strain on the hip joint, leading to discomfort or pain. For instance, nerve and tissue inflammation during surgery can cause temporary numbness, discomfort, or pain in the knee, which can radiate to the hip [2]. Additionally, hip osteoarthritis can present as knee pain, leading to a knee replacement when a total hip replacement is needed [3].
Management of Hip Pain
Managing hip pain after knee replacement involves a combination of physical therapy, pain control, and gradual return to activity under medical guidance.
- Physical Therapy and Exercise: Exercises can help strengthen hip muscles weakened over time due to favoring one leg, improve joint mobility, and restore balanced walking patterns [1][4].
- Pain Management: Pain relievers such as nonsteroidal anti-inflammatories, acetaminophen, and prescription opioids can help reduce swelling and pain. In some cases, a doctor may also recommend muscle relaxers to help with recovery [2].
- Early and Regular Movement: Early and regular movement can prevent complications like blood clots, which can also contribute to pain, and promote circulation and healing [2][5].
- Monitoring and Addressing Nerve Irritation or Ligament Strain: Any nerve irritation or ligament strain that could aggravate hip pain should be monitored and addressed [1].
If hip pain persists or worsens, evaluation for other causes such as hip arthritis or nerve issues may be necessary, with imaging or specialist referral potentially advised [3].
Signs of Complications
While knee replacement surgery is generally safe, potential complications include infection and blood clots. Signs of an infection include the wound being warm to the touch, tenderness and swelling, high fever, visible redness that radiates from the wound area, pain that gets worse whether a person is moving or resting, worsening stiffness, and drainage from the wound [2]. Blood clots can cause pain in the legs, as indicated by a persistent leg cramp-like feeling, skin that is red or warm to the touch, and swelling in the leg [2].
In conclusion, hip pain after knee replacement is often related to postoperative changes in biomechanics and muscle function. It is best managed through a combination of physical therapy, pain control, and gradual return to activity under medical guidance. Having a complete picture of what to expect during the recovery process can help a person recognize when pain requires a visit to the doctor.

- After knee replacement surgery, altered gait mechanics, muscular weakness, nerve irritation, or referred pain can lead to hip pain, highlighting the importance of orthopedic sciences in understanding and managing medical conditions like chronic diseases.
- To alleviate hip pain following knee replacement surgery, immediate actions include physical therapy and fitness and exercise routines aimed at strengthening the hips, improving mobility, and normalizing walking patterns.
- Adequate pain management, including pain relievers, muscle relaxers, and nonsteroidal anti-inflammatories, can help reduce discomfort and improve overall health and wellness during recovery.
- Quality nutrition plays a crucial role in recovery; a balanced diet can help speed up healing and reduce the risk of complications, such as chronic kidney disease.
- Early and regular movement, in accordance with medical advice, can prevent blood clots from caused by immobility and promote faster recovery from therapies and treatments.
- Persistent hip pain may indicate underlying medical conditions like arthritis or nerve issues; thus, it is essential to monitor progress closely and seek advice from healthcare professionals when necessary.
