Knee Replacement
If you’ve been told you need a knee replacement, the next question is who should do it — and how.
The technique matters. The philosophy behind the technique matters more. We use a muscle-sparing approach that preserves the quadriceps tendon, combine it with robotic-assisted precision where it adds value, and perform most procedures as outpatient surgery at Northridge Surgical Suites.
The goal is a knee that performs the way you need it to — for as long as you need it to.
A smaller disruption equals a faster return.
Traditional total knee replacement requires cutting through the quadriceps tendon — the largest muscle group above the knee. It works. But it also means a longer, more demanding rehabilitation while that muscle heals.
Dr. Connors’ approach works around that muscle rather than through it. Using a sub-vastus technique, we preserve the quadriceps entirely — which means less post-operative pain, a faster rehabilitation, and patients who are moving sooner than they expected.
It’s a meaningful difference. Especially for patients under 65 who want their active life back on a shorter timeline.
We also offer the Jiffy Knee system — a specific muscle-sparing approach designed for even faster recovery and a fully outpatient experience. If that sounds like what you’re looking for, it’s worth reading about.
Planned for Your Anatomy. Executed with Precision.
We use the VELYS Robotic-Assisted Solution for knee replacement — not because it’s the most marketed technology, but because it consistently improves implant alignment in cases where individual anatomy makes precision challenging.
Before surgery, a detailed plan is created for exactly where and how your implant should be placed, specific to your knee — not the average knee. In the OR, the system provides real-time guidance that helps execute that plan. The surgeon controls every step. The robot provides the guardrails.
The result is an implant that fits your anatomy the way it was designed to — which is the foundation of a knee that performs well for years.
What Recovery Actually Looks Like.
Most patients who have knee replacement with our approach are walking the same day. Most go home the same day if the procedure is performed at Northridge Surgical Suites. The muscle-sparing technique means less pain in the early days — which means earlier movement, and earlier movement means faster recovery.
The longer arc depends on your goals. Returning to pickleball, skiing, or hiking typically takes three to six months. Physical therapy is part of that — we work with your PT team to calibrate rehabilitation to your specific goals, not just the textbook timeline.
Every patient is different. We’ll be specific with you about what to expect for your situation in the consultation.
Surgery at Northridge Surgical Suites, Nashua.
Most of our procedures are performed at Northridge Surgical Suites — a dedicated outpatient facility built around what joint replacement should feel like. Not a hospital managing twelve other things at once. A calm, focused environment where the staff knows this surgery, the team knows the protocol, and the patient is the only variable that changes room to room.
Most patients go home the same day. For the right patient, that’s not a compromise — it’s a better outcome.
Is Knee Replacement Right for Me?
Knee replacement is the right conversation to have when knee pain is significantly limiting your daily life — and when other treatments like injections, physical therapy, and activity modification have stopped providing meaningful relief. The best way to know whether you’re a candidate is a consultation.
