Partial knee replacement is one of the most effective—and most misunderstood—procedures in orthopedics.

In this episode of the Joint Replacement Podcast, Matthew Sloan takes a deep dive into what partial knee replacement actually is, who it’s for, and why getting it right matters so much.

Many patients ask: “Can I just replace the bad part of my knee?”
The answer is: sometimes—but only if you’re the right candidate.

In this episode, we break down:

• What a partial (unicompartmental) knee replacement really involves
• The three compartments of the knee and why arthritis often affects just one
• Who is a good candidate—and who is not
• Why patient selection is the most important factor for success
• How partial knee compares to total knee replacement
• Why precision and alignment are critical—and how robotics is changing the game

You’ll also learn:

• Why partial knees can feel more “natural” than total knees
• The biggest misconceptions about this procedure
• When a total knee replacement is actually the better option
• And how modern techniques are improving outcomes

The key takeaway:
Partial knee replacement isn’t a “smaller” version of a total knee—it’s a different operation for a specific problem.

When done in the right patient, with the right technique, it can provide excellent outcomes and faster recovery. But when used in the wrong situation, it can lead to early failure.

If you’re considering knee replacement—or just want to better understand your options—this episode gives you a clear, honest, and practical framework to make an informed decision.
