Understanding the Basics
Partial knee replacement (also known as unicompartmental knee arthroplasty) replaces only the damaged part of the knee joint, not the entire knee. It is used when arthritis affects just one compartment of the knee. The procedure relieves pain and improves mobility with less recovery time than total knee replacement.
Inside the Operating Room
During partial knee replacement, the surgeon removes only the diseased compartment of the knee and replaces it with metal and plastic implants. A small incision is made to preserve healthy bone and ligaments around the joint. Specialized tools like oscillating saws, alignment guides, trial components, and cement delivery systems ensure precise fit. Implants often use cobalt-chrome femoral components and titanium tibial trays combined with polyethylene inserts. The procedure may be performed under spinal or general anesthesia in a single operative session. Advanced imaging and trial assembly help restore natural joint motion and alignment.
Medical Reasons for Choosing This Option
- Osteoarthritis confined to a single compartment of the knee (medial or lateral)
- Persistent knee pain that does not respond to medication, injections, or physical therapy
- Functioning knee ligaments, especially the ACL, allowing joint stability
- Patients wish to preserve more bone and maintain more natural knee movement
Orthopedic Devices Involved in Surgery
- Oscillating Saw System (for precise bone resection)
- Alignment Guides and Trial Kits for unicompartmental knee systems
- Arthroscopy Shaver System (used in preparation of joint surfaces)
- Arthroscopy Suction Tubes and Irrigation Pump to maintain clear operative field
- HD Camera System for visualization during joint inspection
- Surgical Power Tools (drills, rasps, curettes) from Orthopedic Division
- Bone Rasps and Curettes used in joint preparation
- Orthopedic Bone Cement for implant fixation
- Arthroscopy Instrument Set including forceps and trocars for joint exposure
- Digital Tourniquet Machine to control limb blood flow during surgery

Positive Outcomes You Can Expect
- Preserves healthy bone and ligaments for more natural knee motion
- Typically results in faster recovery and earlier return to normal activity
- Causes less pain and swelling post-operatively compared to total knee replacement
- Reduces surgical trauma with a smaller incision and less tissue disruption
- Offers improved joint function and range of motion, especially for patients with localized knee arthritis
