The Stone Clinic

What The Stone Clinic does

The Stone Clinic is a private, founder-owned orthopaedic surgery and sports medicine practice headquartered at 3727 Buchanan St #300 in San Francisco, founded by Dr. Kevin R. Stone in 1986. The practice serves active individuals ranging from recreational athletes to professional and Olympic-level competitors, with a particular focus on patients seeking to preserve natural joint biology and avoid or delay artificial joint replacement. The clinic is one of the few dedicated meniscus transplant centers in the world and operates a Robotic Joint Center using the Stryker MAKO system for partial and total knee replacement.

The clinic's core technology stack combines robotic-assisted surgery (Stryker MAKO with CT-guided 3D planning and cementless Triathlon implants) with a proprietary biologic reconstruction platform — BioKnee, BioAnkle, and BioSpineFit programs — that integrates meniscus transplantation using a proprietary three-tunnel technique, articular cartilage paste grafting, ligament reconstruction, and PRP/hyaluronic acid injection therapy. Supporting services include StoneFit specialized physical therapy, shockwave therapy, ACL reconstruction and revision, and a Meniscus Transplant Center with in-house donor tissue acquisition. The Stone Research Foundation, chaired by Dr. Stone, provides a parallel research and outcome-publication arm that supports surgeon training and peer-reviewed validation of techniques.

The business model is fee-for-service professional services delivered through three revenue streams: orthopaedic surgical procedures, StoneFit physical therapy and rehabilitation, and consultations/evaluations (with complimentary virtual consultations used as a patient acquisition mechanism). GTM is a hybrid of sales-led concierge and community-led demand generation: patients are acquired via in-person visits, free virtual consultations for out-of-area and international patients, a traveling-patient concierge service, and a content-driven marketing program anchored by Dr. Stone's weekly blog, video library, podcast appearances, free eGuides, a self-diagnosis symptom checker, and a patient ambassador program organized by sport. Pricing is quote-based and not publicly disclosed, with insurance coverage varying by plan and diagnosis.
