Faster Recovery, Shorter Stays: How Dr. Kelvin Tan and the ERAS Protocol are Transforming Surgery at Gleneagles Hospital

For most patients, the thought of major surgery—like a total knee replacement—is synonymous with a long hospital stay and weeks of limited mobility. However, a recent feature by The Straits Times (published April 29, 2026) highlights how healthcare in Singapore is undergoing a major shift. At the heart of this transformation is Dr. Kelvin Tan, a senior consultant orthopaedic surgeon at Singapore Sports and Orthopaedic Clinic (SSOC), whose leadership in surgical protocols is helping patients “walk out” of the hospital sooner than ever before.

The 18-Hour Milestone

The Straits Times article features the remarkable story of a patient named Michael, who underwent a total knee replacement at Gleneagles Hospital. Just 18 hours after his procedure, Michael was discharged—not in a wheelchair, but walking out of the hospital doors unassisted.

This isn’t a fluke; it is the result of a meticulously designed program known as Enhanced Recovery After Surgery (ERAS), led by experts like Dr. Kelvin Tan.

Who is Dr. Kelvin Tan?

Dr. Kelvin Tan Guoping is a renowned specialist in hip and knee reconstructive surgery and a key figure at both the Singapore Sports and Orthopaedic Clinic and Gleneagles Hospital. Before entering private practice, Dr. Tan was the Clinical Champion for the Knee Replacement Clinical Pathway at Tan Tock Seng Hospital (TTSH) and the lead for the National Healthcare Group’s ERAS Taskforce.

His expertise in robotic-assisted joint replacements and minimally invasive techniques has made him a leading advocate for recovery protocols that prioritize patient readiness and safety over traditional, longer hospitalizations.

What Makes the ERAS Protocol Different?

As Dr. Tan explains in the article, “ERAS isn’t just about sending patients home sooner. It’s about making sure they’re genuinely ready to go.”

The protocol shifts the focus from reactive care to proactive preparation. Here is how Dr. Tan and his team achieve these positive results:

• Multidisciplinary Coordination: The process begins weeks before surgery, involving a “team-based approach” where surgeons, anaesthetists, physiotherapists, and nurses collaborate on a single recovery plan.

• Minimal Trauma: By using advanced technology like robotic-assisted surgery and the “direct anterior approach” for hip replacements, Dr. Tan minimizes muscle damage, which reduces pain and speeds up healing.

• Early Mobilization: The old wisdom of “bed rest” is being replaced. Under the ERAS protocol, patients are encouraged to move within hours of surgery, which significantly reduces the risk of post-operative complications like blood clots.

• Optimized Pain Management: Moving away from heavy sedation allows patients to remain alert and mobile almost immediately after surgery.

Positive Results for Patients

The impact of Dr. Tan’s leadership in implementing ERAS at Gleneagles Hospital is clear. Historically, the average length of stay for a knee replacement was four days. Since the introduction of these protocols, that average has been slashed to just two days, with some suitable patients even heading home the same day.

Beyond the numbers, the true success lies in patient confidence. By empowering patients with the right pre-surgery education and post-surgery support, Dr. Tan is ensuring that they don’t just recover—they bounce back.

A New Standard in Orthopaedics

The Straits Times article serves as a testament to how far surgical care has come in Singapore. Through the vision of Dr. Kelvin Tan and the implementation of the ERAS protocol, the “gold standard” for surgery is no longer just a successful operation—it is a swift, safe, and empowered return to daily life.
