Knee Surgery in Greenwood Village, CO — ACL, Meniscus, MPFL & Arthritis
Knee Conditions
We Treat
Dr. Stephen Thon is a fellowship-trained knee surgeon at Orchard Orthopedics in Greenwood Village, offering arthroscopic treatment for ACL tears, meniscus injuries, and patellar instability — as well as advanced options for knee arthritis, including the MISHA implant, an FDA-cleared alternative to total knee replacement for appropriately selected patients.
For patients who want to exhaust every non-operative option first or who aren't surgical candidates, Dr. Thon also offers regenerative treatments including PRP and BMAC — biologics that use your body's own healing response to reduce pain and support tissue recovery.
Whether you're an athlete recovering from an ACL tear, dealing with a meniscus injury that hasn't responded to conservative care, or looking for options beyond cortisone shots for knee arthritis, Dr. Thon provides a full evaluation with time to discuss every path forward.
No referral required. Same-day and next-day appointments available.
ACL Tears
& Reconstruction
ACL reconstruction for athletes and active adults who need a stable knee and a structured return-to-sport plan. Dr. Thon performs arthroscopic ACL reconstruction with graft selection tailored to your anatomy and activity demand. For appropriate candidates, Dr. Thon can perform the BEAR procedure, a technique that preserves and repairs your native ACL rather than replacing it with a reconstruction. Learn about ACL injuries, symptoms, diagnosis, and treatment options.

MPFL Tears
& Patellar Instability

Dr. Thon performs MPFL reconstruction to reattach and reinforce the medial patellofemoral ligament, with return to sport as the goal. Learn about MPFL tears, patellar instability, and treatment options to restore knee stability.

Knee Arthritis
& MISHA Implant
The MISHA implant is an FDA-cleared alternative to knee replacement for patients with isolated medial compartment arthritis who aren't ready for — or want to avoid — total knee replacement. Dr. Thon is one of a limited number of surgeons in Colorado performing this procedure. Learn about knee arthritis, the MISHA implant, and whether you may be a candidate.
