Persistent knee pain can become so limiting that it affects daily activities such as walking, climbing stairs or even resting at night.
At the Gastaldi Institute in Valencia, we treat patients who live with this reality and seek to restore their quality of life. A knee prosthesis is an effective solution when other treatments have not worked, but how do you know when the time is right?
In this article, we explain the keys to understanding when a prosthesis may be necessary and what to expect from this procedure.
What is a knee replacement and why might it be necessary?
A knee prosthesis is an artificial implant designed to replace a damaged joint, restoring functionality and eliminating pain.
This procedure is mainly indicated in cases of advanced osteoarthritis, a degenerative disease that wears down the articular cartilage and causes friction between the bones. It may also be necessary after severe injuries, such as fractures or irreparable cartilage damage.
The decision to use a prosthesis is not taken lightly. Before reaching this point, patients should have tried conservative treatments such as physiotherapy, infiltrations or biological therapies.
When pain significantly limits quality of life and daily activities, in the final stage of the disease, surgery may be the best option. At ITGO, we combine technological advances with our expertise in joint prosthetic surgery to ensure optimal results.
Symptoms indicating the need for a knee prosthesis
Not all knee discomfort requires surgical intervention, but there aresome symptoms that should not be ignored. If you feel constant pain, even at rest, and it affects your sleep or basic activities, it is time to seek specialist help.
Another important sign is prolonged morning stiffness, accompanied by reduced mobility that makes it difficult to perform simple tasks such as getting out of a chair.
Visible deformity in the joint can also be a sign of severe damage. In these cases, the prosthesis not only improves mobility, but also corrects the alignment and stability of the knee.
When symptoms persist despite conservative treatments, the specialists at ITGO, experts in regenerative and sports medicine in Valencia, will assess whether this surgery is the best option.
What does the intervention consist of?
Knee replacement surgery is a highly advanced procedure performed under general or regional anaesthesia.
During the operation, the damaged joint surfaces are replaced with metal components to replace the articular surface and plastic implants to provide mobility and prevent joint friction, designed to mimic the natural movement of the knee.
The procedure takes one to two hours, and the patient usually stays in the hospital for two to three days to begin recovery. At ITGO, we use state-of-the-art techniques to minimise post-operative pain and speed up the rehabilitation process.
The success of the surgery depends not only on the intervention itself, but also on the patient’s commitment to rehabilitation. For this reason, we combine the intervention with personalised physiotherapy and exercise programmes to guarantee a complete recovery, backed by our experience in traumatology in Valencia.
Benefits of a knee prosthesis
Opting for a knee replacement can radically transform a patient’s life. One of the most obvious benefits is the elimination of pain, making it possible to recover activities that previously seemed impossible, such as walking long distances or playing low-impact sports.
In addition, a prosthesis improves stability and corrects deformities, restoring confidence in every step.
According to recent studies, more than 90% of patients experience a significant improvement in their quality of life after surgery.
For those looking to maintain an active lifestyle, a knee replacement can be the start of a new phase, supported by our joint replacement surgery programmes at ITGO.

Frequently asked questions about knee replacement
How do I know it’s time for a knee replacement?
We consider surgery when pain limits walking, stairs or sleep despite full conservative care (exercise, weight loss, analgesia, bracing and injections).
At our traumatology clinic we combine history, exam and weight-bearing X-rays to decide with you whether surgery will provide more benefit than continuing non-operative care within Valencia traumatology.
Total vs partial knee: how do you choose?
With localised wear and stable ligaments, a unicompartmental knee can preserve more native function and may speed recovery.
With diffuse damage, a total knee replacement restores alignment and pain relief. At Gastaldi in Valencia we decide using axis measurements and functional assessment.
Is age the key factor for indicating a prosthesis?
Symptoms, disability and goals matter more than age alone. We also consider comorbidities, bone quality and activity level to tailor the plan.
Within Valencia traumatology we balance pain relief and implant longevity, and use prehabilitation so you reach surgery stronger.
What is the operation like and how long is the stay?
We use tissue-sparing approaches and fast-track protocols with regional anaesthesia and same-day mobilisation whenever possible.
Length of stay is typically short, and we plan multimodal analgesia and physiotherapy from day one at our traumatology clinic.
When can I drive, return to work and resume sport?
Driving often resumes at 4–6 weeks once strength and control are adequate. Office work returns earlier than standing or heavy-duty roles.
For sport we favour low-impact activities (walking, cycling, swimming, guided gym). Our sports medicine in Valencia unit designs a graded progression to protect the implant.
How long do knee implants last and how do I care for them?
Modern implants often last 15–20 years with healthy weight, good strength and alignment. Regular follow-ups help detect issues early.
At Gastaldi in Valencia we provide exercise and monitoring plans to maximise longevity.
What are the risks and how do you minimise them?
As with any surgery: infection, thrombosis, stiffness or long-term loosening. Rates are low with current protocols and good preparation.
We use antibiotic and thrombo-prophylaxis, multimodal pain control and structured rehab at our traumatology clinic to reduce complications.
Can biologics or alignment procedures avoid a replacement?
In mild-to-moderate OA, orthobiologics and exercise may delay surgery. In selected cases, offloading or alignment procedures can buy time.
If pain remains limiting, replacement offers stable relief. We decide together within Valencia traumatology.
Do you work with insurers and how do I start?
Yes, we manage approvals, imaging and rehabilitation with your policy to keep the journey clear and efficient.
