Knee replacement may be considered when pain, stiffness, or deformity substantially reduces the ability to walk, climb stairs, sleep, work, or manage daily activities. It is not recommended only because of age, an X-ray, or the diagnosis of arthritis.
The consultation is designed to answer three questions: what is causing the symptoms, which alternatives remain reasonable, and whether replacement offers an appropriate balance of expected benefit, risk, and recovery demands.
When should knee replacement be evaluated?
An evaluation may be useful when several of the following are present:
- Frequent pain that limits walking, stairs, or rising from a chair.
- Pain at rest or during the night.
- Stiffness that limits bending or straightening the knee.
- Persistent swelling or progressive deformity.
- Loss of independence or a major reduction in activity.
- Inadequate response to non-surgical options that are appropriate for the case.
These findings do not prove that replacement is required. Other causes of pain, the overall condition of the joint, and the patient’s functional goals must also be reviewed.
What is reviewed before surgery is recommended?
The evaluation generally includes:
- Location, severity, and progression of pain.
- Activities that are no longer possible or require assistance.
- Knee motion, strength, stability, and leg alignment.
- Hip, ankle, spine, circulation, or nerve findings when relevant.
- Weight-bearing X-rays to evaluate the distribution of arthritis and deformity.
- Previous treatments, their results, and tolerance.
- General health, medications, home support, and functional goals.
MRI is not required for every patient. It is ordered when it may provide information that changes the decision.
Options that may still be considered before replacement
Depending on the case, it may still be reasonable to discuss activity modification, rehabilitation, walking aids, weight management, medication directed by the treating physician, or other applicable options. See non-surgical treatment options.
Surgery should not be presented as automatic, and it should not be delayed only to satisfy a fixed period of conservative treatment.
Total and partial knee replacement are not interchangeable
Total knee replacement
May be considered when arthritis affects multiple areas of the knee, deformity is substantial, or the joint is not suitable for a partial procedure. It replaces damaged joint surfaces, not the entire knee.
Partial knee replacement
Limited to selected patients with arthritis in one compartment and suitable motion, stability, and ligament function. It is not automatically better and is not appropriate for every patient.
The choice is confirmed after symptoms, examination findings, and X-rays are correlated. Implant type, fixation, and availability are defined during individual planning; brands are not promised from a webpage.
What may improve and what cannot be promised
The goal is to improve pain and function for daily activities. It is not possible to guarantee:
- A knee identical to a healthy joint.
- Complete absence of pain or stiffness.
- Recovery by one universal date.
- Return to high-impact sport.
- A specific implant lifespan for an individual patient.
Recovery is based on goals, not a rigid calendar
Progression is adapted to the procedure and the patient’s response. Common goals include:
- Control of pain and swelling.
- Wound care and recognition of concerning changes.
- Gradual restoration of extension and flexion.
- Safe transfers, walking, and use of assistive devices.
- Quadriceps, hip, and supporting muscle strength.
- Balance, stairs, and daily activities.
- Progressive return to work, driving, and permitted exercise.
The timing for discontinuing a walker, driving, or returning to work should not be promised in advance. Progress depends on preoperative condition, the procedure, medical conditions, home support, and rehabilitation response.
Preparation and logistics
Before possible surgery, the team reviews imaging, general health, medications, skin condition, possible infection sources when relevant, home support, and transportation. Final instructions must come from the treating team; this page does not replace preoperative guidance.
Risks and limitations to discuss
As with any major operation, knee replacement may involve infection, blood clots, stiffness, persistent pain, nerve or blood vessel injury, wound problems, instability, implant wear or loosening, and additional surgery.
Individual risk varies with functional age, medical conditions, medications, skin condition, mobility, body weight, smoking, and other factors. Prevention measures are selected for the individual patient; universal medication protocols are not published here.
Cost, hospital, and insurance
The estimate is not based on the implant alone. It may include:
- Hospital, operating room, stay, and supplies.
- Implant components selected for the case.
- Anesthesia and the clinical team.
- Preoperative testing and consultations.
- Professional fees.
- Rehabilitation, follow-up, and additional needs.
Consultations take place at Hospital Punta Mita in Corral del Risco. The surgical facility, availability, estimate, and logistics are confirmed after evaluation.
Insurance coverage must be verified directly with the policy and the institutions involved. Direct billing or acceptance of a specific insurer cannot be guaranteed from the website.
Patients traveling from outside the area should plan transportation, a companion, local stay, and follow-up. See information for international patients.

Frequently asked questions
Does arthritis on an X-ray mean I need a knee replacement?
No. Imaging must be correlated with pain, disability, mobility, stability, deformity, and the response to other treatment options.
How is total versus partial replacement decided?
Partial replacement is limited to selected patients with arthritis in one compartment and suitable ligament stability and motion. Total replacement may be considered when damage is more extensive or a partial procedure is not appropriate.
Do I need an MRI before the consultation?
Not necessarily. Weight-bearing X-rays often provide important information about arthritis and alignment. Other studies are requested when they may change the decision.
Will knee replacement remove all pain?
Complete pain relief or a knee identical to a healthy joint cannot be guaranteed. The aim is to improve pain and function in appropriately selected patients.
How long does recovery take?
There is no universal schedule. Progress depends on preoperative condition, the procedure performed, wound healing, motion, strength, balance, medical conditions, and functional goals.
How long does a knee implant last?
Implant longevity varies among patients and depends on activity, body weight, alignment, implant factors, general health, and follow-up. Population data should not be presented as an individual guarantee.
How is the estimate calculated?
An estimate is prepared after evaluation and may include the hospital, implant, supplies, anesthesia, professional fees, testing, and individual needs. A reliable amount cannot be published without reviewing the case.
Can I use medical insurance?
Coverage, authorization, reimbursement, and possible direct billing depend on the policy, hospital, and individual case. Feasibility must be confirmed directly.
Where does the evaluation take place?
Consultations take place at Hospital Punta Mita in Corral del Risco. The surgical facility and logistics are confirmed only after the case has been evaluated.
