Service highlights include:
- Fracture repair
- Arthroscopy
- Tenoscopy and bursoscopy
- Advanced cartilage resurfacing
- Regenerative medicine including stem cells and platelet-rich plasma
Soft Tissue Surgery
In addition to upper respiratory surgery, New Bolton Center’s surgery team addresses numerous and diverse areas of soft tissue surgery. Many of the surgeries can now be performed using minimally invasive techniques (i.e., laparoscopically), often without the need for general anesthesia.
Service highlights include:
- Laparoscopic surgery for treatment of cryptorchids, ovarian tumors or other urogenital problems
- Laparoscopic nephrosplenic space ablation for recurrent colon entrapments
- Urogenital surgery
- Wound and laceration repair
- Treatment of tumors, including sarcoids, melanoma, and others, with the most advanced treatment options including autologous vaccine preparation
Upper Airway Surgery
Diseases and abnormalities of the upper airway cause poor performance in sport horses. Our New Bolton surgeons specialize in upper airway surgery, providing issue-specific diagnostics and innovative surgical treatment approaches.
Service highlights include:
- Modified laryngoplasty (tieback) for treatment of laryngeal hemiplegia
- Outpatient transendoscopic laser surgery for removal of growths or correction of epiglottic entrapment
- Outpatient dental treatment or extractions performed by a certified veterinary dentist
- Outpatient sinoscopy for evaluation and treatment of sinus disease
- Tieforward procedure for treatment of palate displacement

Research in Surgery
New Bolton Center’s Surgery faculty are actively engaged in innovative research, including stem cell therapy, bone growth and regeneration, and stimulating the synthesis of cartilage components in the treatment of equine arthritis, positioning New Bolton and Penn Vet as an international leader in the field of equine musculoskeletal research.
Ortved Orthopedic Regenerative Medicine Laboratory
At the Ortved Laboratory, we are focused on understanding the pathogenesis of PTOA and developing regenerative medicine therapies to improve musculoskeletal healing using the horse as a model for human disease. Specifically, we are interested in gene, signal, and cell-based therapies to improve cartilage repair and prevent osteoarthritis. Dr. Ortved’s clinical work as an equine orthopedic surgeon facilitates translation of this research from bench to clinic floor.
