Hip & knee replacement for Gaithersburg patients
Gaithersburg patients have one of the shortest commutes in the practice — the Germantown office is essentially next door, and the Capital Orthopedic Surgery Center sits just up I-270 in Germantown as well.
Where Gaithersburg patients see Dr. Harb
Dr. Harb sees patients from Gaithersburg at both offices — whichever fits your schedule and routine best.
- The Germantown office at 20410 Observation Drive — essentially down the street, typically 10–15 minutes up I-270, with free on-site parking
- The Washington, D.C. office at 1015 18th Street NW — about 30–40 minutes south via I-270 / Wisconsin Avenue or the Red Line, convenient for patients who work or have other commitments downtown
Both offices handle the full range of in-office care.
Surgery just up the road
For most primary hip and knee replacements, surgery is performed at the Capital Orthopedic Surgery Center (COSC) on Seneca Meadows Parkway in Germantown — about 15 minutes from most of Gaithersburg via I-270. COSC is an outpatient-focused surgical facility built around joint replacement.
For revision surgery or medically complex cases, Dr. Harb operates at Johns Hopkins Sibley Memorial Hospital in Washington, D.C. The drive is longer, but Sibley is the right setting when a full hospital level of care is needed.

What sets the practice apart
- The closest office to Gaithersburg. Germantown is essentially next door — short drive, no traffic, free parking.
- Same corridor for everything. Consultation, surgery, and follow-up all happen along the same short stretch of I-270.
- Direct anterior hip replacement — a muscle-sparing approach that lets most patients walk the same day and recover at home.
- Modern, rapid-recovery knee replacement — a soft-tissue–respecting approach with detailed preoperative templating and modern medial-pivot implant designs, supporting early walking and a smoother return to daily life.
- High surgical volume — over 600 hip and knee replacements each year, with over 5,000 to date.
Procedures available
Gaithersburg patients are seen for the full range of hip and knee care, including hip replacement, knee replacement, direct anterior hip replacement, partial knee replacement, and outpatient (same-day) joint replacement.
