Kaliber™ is using AI to bring meaningful change to surgery.

We're a team of surgeons and AI researchers working together to improve surgery for surgeons, patients, and healthcare systems everywhere.

The surgical journey

Before Kaliber

When patients are scheduled for surgery, they receive pages of forms and pre-op instructions. Overwhelmed patients often look up their surgeries online – only to wind up doomscrolling through distressing, misleading information.

Patients anxiously wait several weeks to meet with their surgeons again, building up a backlog of concerns  – more than surgeons can fully address in a brief pre-op consultation.


Surgical procedures aren't always straightforward due to unexpected findings. Surgical workarounds take

additional time, increasing stress on surgeon and patients – and delaying other scheduled surgeries.

Surgeons explain post-op instructions to their patients and family members – but patients are often still groggy, and family members may be distracted and focused on getting home. Patients are discharged with pages of post-op instructions they may not fully understand, and that may not cover their unique case. 

Key findings from surgery can easily get lost in the shuffle of paperwork between the surgical team, the patient, their family, physical therapists, and healthcare providers. This can lead to misalignments in care that slow recovery.

High stress contributes to surgeon burnout, leaving healthcare systems with fewer qualified surgeons to carry the patient load – which means patients end up living with pain longer while awaiting surgery. 

Complications mean that, at best, standard physical therapy may be slower than expected. If a patient still isn't improving, additional treatment and/or surgery may be needed. This follow-up care can be painful and expensive for patients, stressful for surgeons, and can stretch healthcare system resources.

With Kaliber Rekap™, patients can get acquainted with their surgeons, watch surgeon-approved videos explaining their procedure, and review useful pre-op instructions – so they enter the OR feeling informed, confident, and prepared for surgery.

Surgeons perform surgery with assistance from Kaliber Kopilot™, which can help identify anatomy, spot anomalies, and ensure that measurements and landmarks are precise. This helps surgeons perform consistent, accurate surgeries with less stress.

Patients and their families can leave the hospital without worrying about the paperwork. Instead, they can review their surgeons' aftercare advice anytime using Kaliber Rekap. Clearly labeled before and after images from their surgery help patients explain their surgery to family and physical therapists.

Physical therapists and healthcare providers use the Rekap patient portal to create a unified care plan for effective, efficient recovery. Pain, stress, and costs are minimized for patients, surgeons, and the healthcare system – so there are more available resources to share with more patients in need.

What the experts say

"It’s clear that Kaliber is committed and has invested the time and energy to understand surgeons’ needs. Its AI surgical tools–from bluDot™ virtual landmarking to instantaneous digital measurement to AI-driven recognition of anatomy and pathology–are unlike anything we currently have in the operating room. But it’s not just about novelty: these are solutions to real problems, and they stand to make an incredible difference in surgical performance for early-career and experienced surgeons alike. And by making a difference for surgeons, Kaliber’s making a difference for patients, too.”

“Kaliber’s measurement system eliminates the guessing game and provides objective and consistent measurements that can guide surgical decision-making. I am excited by Kaliber's complementary bluDot™ technology that can assist surgeons with any level of experience to surgically plan for instrumentation use and implant placement.”

"The tools that Kaliber is building have the potential to dramatically reduce surgical variability and expand access to proficient care for patients undergoing minimally invasive surgery. These are tools that surgeons have been talking about for years, but only in theory because no one has been able to figure out how to build them until now.”

"Kaliber’s potential to objectively assess operative performance is a game-changer. Far beyond the simple recognition and labeling of anatomy, surgical templates guide the novice surgeon in ‘best practices’ as they learn new techniques. Without question, the patients will benefit from better and safer procedures."

"Many procedures, including ACL reconstruction, require precise identification of anatomic landmarks at all times during arthroscopy. Kaliber’s bluDot™ and AI measurement technology not only guides the surgeon to the correct location, but provides real time confirmation of these anatomic locations regardless of camera orientation or viewing portal. This technology does not exist in any other format. This is truly revolutionary and will become the gold standard for every orthopedic surgeon."
