Knee Pain After Hip Replacement: Is It Normal?

If you’re experiencing knee pain after hip replacement, you may wonder if it’s a normal part of the healing process. As with any major surgical procedure, a degree of discomfort is anticipated, especially during the early stages of recovery when your body is still adjusting to the changes and healing from the trauma of surgery. This discomfort is typically localized around the surgical area. However, knee pain, while somewhat less common, can also be part of this initial recovery phase.

What’s crucial is the ability to discern normal healing discomfort from pain that could signify more serious issues. Persistent or severe knee pain could be a red flag, indicating potential complications or underlying conditions that must be addressed. It could be as simple as overexertion during physical therapy or a more complex issue like nerve damage or infection. Understanding what’s normal and when to seek additional medical attention is vital to ensure a healthy recovery and optimal post-surgery outcomes.


The hip joint and knee joint are interconnected parts of your lower body’s biomechanical system. When one component undergoes major changes, like hip replacement surgery, it can impact the others, potentially leading to knee pain. Understanding this complexity can help you manage and alleviate symptoms.

Causes of Knee Pain After Hip Replacement

Experiencing severe pain after a hip replacement is not typical and should be addressed immediately with your healthcare provider. This pain could originate from several factors, such as infection, nerve damage, or complications from surgery. It might be acute, which appears suddenly and intensely, or chronic, presenting as persistent, ongoing discomfort. In both cases, don’t hesitate to seek professional medical advice.


One possible cause of knee pain after hip replacement is infection. An infection in the hip can spread to the knee through your bloodstream. Symptoms of an infection may include swelling, redness, warmth, and pain. For more information on infection after surgery, visit the Centers for Disease Control and Prevention (CDC).

Mechanical problems

Another reason could be mechanical problems. Changes in your gait after a hip replacement, such as limping or kneeling after hip replacement, can place extra stress on your knee, leading to pain. Additionally, these issues can cause a painful knee after hip replacement. Working with a physical therapist on proper posture and walking techniques can greatly alleviate these mechanical problems and reduce knee pain.


What causes thigh and knee pain after hip replacement can sometimes be linked to neuropathy, a condition that occurs when nerves in the leg are damaged or compressed. This may result in sensations of tingling, numbness, and pain radiating from the hip down to the knee. If you’re experiencing these symptoms, it’s important to inform your healthcare provider promptly, as early diagnosis and treatment can improve the prognosis of neuropathy.


Post-surgery stiffness can also cause knee pain. This often results from reduced activity levels during recovery, leading to stiff joints and muscles. Maintaining gentle movement and regular physical therapy can help alleviate stiffness.

Muscle weakness

Lastly, muscle weakness may lead to knee pain—the muscles around your hip and knee work together to maintain stability and movement. If your hip muscles are weakened due to surgery, your knee may bear more weight, leading to pain. A tailored physical therapy program involving strength training exercises can help restore muscle balance and mitigate the additional strain on the knee.

How to Manage Knee Pain After Hip Replacement

It’s important to grasp that the causes of knee pain after hip replacement can be numerous and varied. The interconnectedness of our bodily systems means that an issue in one area can often lead to problems in another. Something like anterior thigh pain could stem from a hip-related issue. Likewise, complications from a knee replacement surgery could cause pain in the hip and vice versa.

Pain management is a key aspect of recovery from any major surgical procedure, including a hip and knee replacement. This often involves a combination of pain medications and physical therapy. However, it’s important to use these medications as directed by your healthcare provider, as overuse can lead to other health complications. Furthermore, complications such as a hip fracture following replacement surgery, although rare, can contribute to knee pain. If you suspect a fracture, seek medical attention immediately.

If the initial hip replacement does not heal properly or has other issues, revision surgery may be necessary, leading to knee pain. Hip-related groin pain can also manifest as pain in the knee due to the proximity and interconnectedness of these areas.

Physical therapy can help strengthen the muscles around the hip and knee, improving stability and reducing pain. Over-the-counter medications or prescription drugs may also be recommended to manage pain and inflammation. Lifestyle changes like weight management and a healthy diet can support overall joint health.

Treatment Options For Knee Pain After Hip Replacement

1. Physical Therapy

Physical therapy is a pivotal element in the hip replacement recovery process, targeting persistent knee pain that can occur post-surgery. Tailored exercises aim to enhance strength, flexibility, and joint function, critical for patients undergoing hip arthroplasty. This approach not only aids in managing joint pain but also in optimizing overall mobility during the recovery period.

2. Medications

Pain after surgery, including discomfort following joint replacement surgery, can often be managed effectively with over-the-counter pain relievers such as ibuprofen. For hip replacement patients experiencing more severe or persistent pain, prescription medications may be necessary. These medications should be used judiciously, as directed by clinical practice, to minimize side effects and ensure the safety of the artificial joint.

3. Ice and Heat Therapy

Implementing ice and heat therapy is beneficial for reducing inflammation and alleviating pain after knee replacement. Ice packs can help numb the area, reducing acute discomfort, while heat therapy facilitates muscle relaxation and promotes healing by increasing blood flow to the affected joint.

4. Activity Modification

Modifying activities to prevent aggravation of knee pain is crucial for individuals who have undergone hip arthroplasty. Avoiding actions that place excessive stress on the new joint during the hip replacement recovery phase can prevent the risk of deep infection and ensure the longevity of the artificial joint.

The Final Stretch

While some discomfort is normal following hip replacement surgery, persistent or severe knee pain should not be ignored. It’s important to communicate with your healthcare provider about any pain or discomfort you’re experiencing.

Always consult with your private hip surgeon to discuss the best options for your situation. If you’re concerned about the private hip replacement price, be sure to discuss this with your healthcare provider.

Think of your recovery journey as a marathon, not a sprint. It’s essential to remain patient and remember that full recovery from a hip replacement can take time. Following your doctor’s advice, participating in physical therapy, and caring for your overall health are all integral parts of this process. With time, consistency, and professional guidance, your knee pain can be alleviated, paving the way for a smoother stride toward recovery.


1. How do you get rid of knee pain after hip replacement?

Combining physical therapy, medication, ice and heat therapy, and careful activity modification is essential for addressing knee pain. These strategies are cornerstones of clinical practice for managing discomfort and enhancing recovery after hip joint replacement surgery.

2. How can I strengthen my knee after hip replacement?

Engaging in specific exercises under the supervision of a physical therapist is key to strengthening the knee and supporting structures after hip replacement. This approach is vital for mitigating joint pain and facilitating a smooth recovery period.

3. What happens if you don’t exercise after hip replacement?

Failure to adhere to a prescribed exercise regimen can lead to increased stiffness, joint pain, and a prolonged recovery period. Exercise after hip arthroplasty is critical for preventing the exclusion criteria such as reduced mobility and the potential for persistent pain, ensuring the success of the joint replacement surgery.
