Services & Procedures
Comprehensive orthopaedic surgical care — from day-surgery joint replacement to arthroscopy, trauma management, and sports injuries.
Total Knee Arthroplasty
Dr. Watts performs total knee arthroplasty (TKA) as a day-surgery procedure at Oak Valley Health's Markham Stouffville Hospital, using the Stryker Triathlon Total Knee System. Most patients are mobile and return home the same day of surgery.
TKA is indicated for end-stage knee arthritis that has not responded to conservative measures, and is one of the most effective and reproducible surgical interventions in orthopaedics.
Indications
Recovery Timeline
Stryker Consultant Disclosure: Dr. Watts is a paid consultant for Stryker Orthopaedics and uses Stryker implant systems in his surgical practice. This relationship is fully disclosed to all patients.
Oak Valley Health has produced a comprehensive patient information booklet covering what to expect before, during, and after total knee replacement.

Dr. Watts uses the direct anterior approach — often called the "bikini incision" technique — for total hip arthroplasty (THA). This muscle-sparing approach accesses the hip through a natural interval between muscles without cutting through or detaching them.
Dr. Watts uses the Stryker Trident cup, Accolade II stem, and Insignia stem system, paired with ceramic femoral heads for superior wear performance. Most patients with appropriate medical fitness are eligible for day surgery. Hip precautions are not required in most cases due to the preserved soft tissue envelope.
Approach Advantages
No major muscle detachment — reduced pain and faster functional recovery
Preserved soft tissue envelope provides inherent stability in most patients
Many patients return home same day with appropriate support
The incision is closed entirely with internal absorbable sutures for a cosmetic finish. No staples, no clips, and no post-operative suture removal appointment required.
Implant System
Oak Valley Health has produced a comprehensive patient information booklet covering what to expect before, during, and after total hip replacement.

Revision arthroplasty involves replacing or repairing a previously implanted hip or knee prosthesis that is no longer functioning optimally. Dr. Watts performs both revision total hip arthroplasty and revision total knee arthroplasty for patients experiencing implant failure, aseptic loosening, instability, infection, or ongoing pain following a prior joint replacement.
Revision surgery is more technically complex than primary arthroplasty and requires thorough preoperative planning, patient-specific implant selection, and experienced surgical technique. Each case is assessed individually to determine the appropriate surgical approach and implant strategy.
Common Indications
ACL Reconstruction
Anterior cruciate ligament (ACL) reconstruction is performed arthroscopically. Dr. Watts tailors the graft choice to each patient's anatomy, activity goals, and knee anatomy, including the use of allograft tissue where appropriate.
The procedure involves creating a new ligament graft through drill tunnels in the femur and tibia, restoring rotational stability to the knee. Rehabilitation is critical to achieving full return to sport.
Graft Options
Meniscal & Knee Arthroscopy
Knee arthroscopy is a minimally invasive surgical technique using a small camera (arthroscope) inserted through tiny incisions to diagnose and treat a range of intra-articular conditions. Most procedures are performed as day surgery with rapid recovery.
Conditions Treated
Meniscal Preservation
Dr. Watts prioritizes meniscal repair over partial meniscectomy when the tear pattern and tissue quality are amenable to repair. Preserving meniscal tissue protects the underlying cartilage and reduces long-term risk of knee osteoarthritis.
Trauma & Fracture Management
Dr. Watts manages acute fractures and complex peri-articular fractures at two hospital sites, offering accessible trauma care for patients in the York Region and City of Kawartha Lakes.
