Surgical details
Modern partial knee replacement is designed to treat the worn compartment while preserving as much normal knee anatomy as possible.
Modern Surgical Techniques
- Minimally invasive approach (3-5 cm incision)
- Robotic-assisted precision for optimal implant positioning
- Minimal bone resection preserving natural knee anatomy
- Advanced implant materials (oxidized zirconium, highly cross-linked polyethylene)
- Cemented or cementless fixation options
- Surgical time: 30-60 minutes
- Same-day discharge or overnight stay
- Accelerated rehabilitation protocols
Surgical Procedure
Partial knee replacement is performed under regional anesthesia (spinal or epidural) with sedation, or general anesthesia. The procedure uses a minimally invasive approach with a small incision (typically 3-5 cm) that preserves the quadriceps tendon and minimizes soft tissue disruption.
Modern techniques often incorporate robotic assistance, which provides sub-millimeter precision in bone preparation and implant positioning. This technology helps ensure optimal alignment and balance, potentially improving long-term outcomes and reducing revision rates.
The surgery involves minimal bone resection, preserving the patient's natural knee anatomy and cruciate ligaments. Advanced implant materials include oxidized zirconium femoral components for reduced wear and highly cross-linked polyethylene tibial inserts for enhanced durability.
Recovery and Rehabilitation
Most patients are discharged the same day or after an overnight stay. Enhanced recovery protocols include multimodal pain management, early mobilization, and structured physical therapy. Patients typically walk with minimal assistance within 1-2 weeks and return to normal activities within 4-6 weeks.
Modern rehabilitation emphasizes early range of motion, strengthening exercises, and functional training. Many patients achieve excellent outcomes with outpatient therapy programs, though some may benefit from formal physical therapy for 6-8 weeks.
