When Is Knee Replacement Recommended?
Knee replacement is considered when arthritis has worn away the cushioning cartilage in the knee, causing pain and stiffness that limit walking, stairs, and daily activities — and when nonsurgical treatments no longer provide meaningful relief.
Not every arthritic knee needs the same solution. Some patients have damage limited to one compartment of the knee and are excellent candidates for partial knee replacement. Others have more widespread arthritis requiring total knee replacement. Dr. Kee carefully evaluates your X-rays, exam, and lifestyle to recommend the option that gives you the best long-term outcome with the least invasive approach possible.
Robotic-Assisted Precision
Whether you're a candidate for partial or total knee replacement, Dr. Kee uses robotic guidance to plan and perform your surgery with precision tailored to your specific anatomy — helping ensure accurate alignment and balanced soft tissue tension. This foundation applies to both procedures below; the right one for you depends on how much of the knee is affected.
Robotic-Guided Precision
Robotic guidance helps ensure accurate bone preparation, implant positioning, and alignment tailored to your anatomy — not a standard template.
Minimally Invasive Technique
A quadriceps-sparing approach, used whenever possible, reduces trauma and supports a smoother recovery.
Partial Knee Replacement
Also called unicompartmental knee arthroplasty (UKA), partial knee replacement resurfaces only the damaged portion of your knee — usually the inner (medial) or outer (lateral) compartment — while preserving healthy bone, cartilage, and ligaments, including the ACL in most cases.
Think of your knee like a three-lane highway. If only one lane has deep potholes, why repave the entire road? Partial knee replacement resurfaces just the damaged compartment while leaving the healthy lanes untouched.
Key Benefits of Partial Knee Replacement
- Less invasiveSmaller incision, less bone removed, muscles and ligaments preserved
- Faster recoveryMany patients walk the same day and return to activities sooner, often within 4–8 weeks for major milestones
- More natural feelPreserves your own ligaments and healthy compartments for better movement
- Lower blood lossTypically less post-operative pain
- Easier future revisionIf arthritis develops later in other compartments, conversion to total knee is more straightforward
Is Partial Knee Right for You?
Ideal candidates generally have:
- Arthritis isolated to one compartment
- Intact anterior cruciate ligament (ACL)
- Correctable leg alignment deformity
- Good range of motion
- No significant inflammatory arthritis
Dr. Kee uses weight-bearing X-rays, including specialized views, and a thorough exam to confirm candidacy.
Why Robotic Precision Matters for Partial Knee
Robotic guidance is particularly valuable for partial knee replacement. Precise planning and real-time feedback help ensure accurate implant positioning and soft-tissue balance in the affected compartment while protecting the healthy parts of your knee — often improving accuracy, functional scores, and long-term implant survival compared to conventional techniques.
Total Knee Replacement
When arthritis affects multiple compartments or the knee has more advanced deformity, total knee replacement provides reliable, durable relief using the same technology-enhanced, quadriceps-sparing approach described above.
Partial vs. Total Knee Replacement
Dr. Kee helps you choose the right option based on your arthritis pattern, ligaments, and activity goals. For appropriately selected patients, research shows partial knee replacement can deliver pain relief and function similar to total knee replacement, with fewer complications and a faster initial recovery.
| Factor | Partial Knee | Total Knee |
|---|---|---|
| Arthritis pattern | Isolated to one compartment | Multiple compartments or widespread |
| Bone & ligament preservation | High — often preserves ACL | Full joint resurfacing |
| Incision & tissue disruption | Smaller, less invasive | Standard |
| Typical recovery pace | Often faster — 4–8 wks major milestones | 7–12 wks for major milestones |
| Future revision | Easier conversion to total if needed | Standard revision pathway |
| Same-day discharge | Often possible | Offered for eligible patients |
Recovery
Partial Knee — Often Faster
Many patients walk the same day, return to daily activities quickly, and often need less formal PT long-term. Return to golf and recreational sports is frequently possible in 6–10 weeks.
Total Knee — Structured Recovery
Same-day discharge is offered for eligible patients. Active rehabilitation is key, with major recovery milestones typically reached in 7–12 weeks.
Recovery requires active rehabilitation — restoring full range of motion is central to a good outcome. See the Total Knee PT Protocol for a week-by-week guide. Partial knee patients often follow an accelerated version — this will be discussed during your visit.
