Do I Need a Knee Replacement, or Can I Wait? A Torrance Surgeon's Guide

By Shaun E. Chandran, M.D. — Chandran Orthopaedic Surgery, Torrance, CA

If knee pain is starting to shape your day — which chair you choose, which stairs you avoid, whether you say yes to a walk — you've probably wondered whether it's time for a knee replacement, or whether you should hold off. It's one of the most common questions I hear from patients across the South Bay, and the honest answer is: it depends on more than your X-ray.

Here's how I think through it with patients in my Torrance practice.

Knee replacement is rarely an emergency

With very few exceptions, knee arthritis doesn't damage anything by waiting. That means you largely get to decide when the trade-off makes sense, based on how much the pain is costing your quality of life. Surgery becomes the right call when the knee is limiting the life you want to live and non-surgical options have stopped working — not simply because a scan looks bad.

Signs it may be time to consider surgery

• Pain that interrupts sleep or is present at rest, not just with activity.
• You've plateaued on conservative care — anti-inflammatories, physical therapy, weight management, activity modification, and injections no longer give meaningful or lasting relief.
• Your world is shrinking — you're giving up walks, travel, golf, pickleball, or time with grandkids because of the knee.
• Mechanical symptoms like buckling, locking, or significant stiffness.
• X-rays show bone-on-bone arthritis that matches your symptoms.

When several of these line up, replacement tends to deliver excellent, durable pain relief.

Reasons it may be reasonable to wait

• Your pain is real but still manageable with conservative treatment.
• You haven't yet given physical therapy or weight management a genuine trial — both can meaningfully reduce knee load and pain.
• You have a major life event or trip coming up and recovery timing doesn't work.
• Other health issues should be optimized first to make surgery safer.

Waiting is a legitimate choice. The goal isn't to delay forever or to rush in — it's to operate at the point where the benefit clearly outweighs the recovery.

What modern knee replacement actually looks like

A lot of patients are still picturing the long, difficult recoveries of decades ago. Today's joint replacement is different. In appropriate candidates we use minimally invasive and robotic-assisted (Makoplasty) techniques that allow for more precise implant positioning, and many patients go home the same day or the next. A well-done, well-positioned knee replacement commonly lasts 15–20+ years.

How we'll decide together

At your visit we'll review your history, examine the knee, look at your imaging, and — just as importantly — talk about your goals. Two patients with identical X-rays can need completely different plans. My approach is conservative: I'll exhaust the reasonable non-surgical options with you first, and recommend surgery when it's genuinely the best path to getting your life back.
