What is a subchondral insufficiency fracture?

It is a stress fracture in the bone just beneath the cartilage, often seen as a bone marrow lesion on MRI. It can cause sudden, deep, aching joint pain and is sometimes mistaken for a meniscus tear. Left untreated, it can progress toward joint surface collapse and, eventually, joint replacement.

Does the KneeBar cure arthritis or regrow cartilage?

No. The goal of the KneeBar is to support and offload the injured subchondral bone so it can heal, which may relieve pain and help delay or avoid a knee replacement in the right patient. It does not cure arthritis and it does not regrow cartilage. Candidacy is determined by your MRI and exam.

How is the KneeBar different from a knee replacement?

A replacement removes and resurfaces the joint with metal and plastic. The KneeBar is a much smaller, bone-preserving, percutaneous procedure that leaves your own joint intact and uses a metal-less, bio-integrative implant that your body remodels into bone over time, per the manufacturer.

In-Office · Less-Invasive Procedures

Advanced procedures, in the office,
not the operating room.

Many diagnoses, small procedures, and even bone-preserving knee procedures can be done awake, in the office, with less downtime, no hospital, and one transparent price.

In-Office Needle Arthroscopy

See inside the joint, awake, in a single visit

Needle arthroscopy uses a camera about the width of a needle to look directly inside a joint under local anesthesia, right in the office. For the right problem, it can give a clearer, faster answer than waiting on an MRI, and it lets us handle small procedures in the same setting.

Direct diagnostic look at cartilage, meniscus, and soft tissue
Small procedures: biopsy, loose-body removal, minor debridement
Local anesthesia, awake, no hospital and no general anesthesia
Fast answers and minimal downtime, at one clear price

Office-Based Knee Preservation

The KneeBar for subchondral insufficiency fractures

Sudden, deep, aching knee pain in an active adult is not always a meniscus tear. Often it is a subchondral insufficiency fracture, a stress fracture in the bone just under the cartilage that shows up as a bone marrow lesion on MRI. Left alone, it can progress toward joint collapse and, eventually, replacement.

The KneeBar is a percutaneous, fluoroscopy-guided procedure that places a metal-less, bio-integrative implant to support and offload that injured bone so it can heal. The implant is made from minerals your bone is built from and is gradually replaced by your own bone over time, per the manufacturer.

Targets the true pain source: the subchondral bone, not just the cartilage
Percutaneous and bone-preserving, metal-less fixation
May help relieve pain and delay or avoid a knee replacement
Often paired with biologics (BMAC or PRP) in the same plan

Three stages of bio-integration: fixation, healing, and a fully healed implant replaced by the patient's own bone — How a metal-less, bio-integrative implant works: it holds from day one, then is gradually replaced by your own bone, leaving only natural tissue behind.

Honest expectations: the KneeBar does not cure arthritis and does not regrow cartilage. It is one tool for the right patient, and candidacy is determined by your MRI and exam. Learn more about our the KneeBar procedure and regenerative options.

Questions

In-office procedures, answered.

Yes. In-office needle arthroscopy is performed under local anesthesia. You are awake, the joint is numbed, and most people drive themselves home and return to light activity quickly.

Every in-office knee procedure has a published price: $4,200 for a wide-awake loose-body removal or synovectomy, $4,250 for a chondroplasty, $4,500 for a meniscectomy, $6,000 for a quad or patellar tendon repair, and $7,000 for the KneeBar (subchondroplasty), with the full list on our pricing page. Because they are done in the office rather than a hospital, they avoid facility fees. Our office surgery program opens December 2026: every price is published now, the list is open, and we schedule you when the suite opens. Diagnostic needle arthroscopy and anything not listed is quoted per case, in writing, before anything is scheduled.
