JUST SKII PS Total Knee Revision Surgery Case Study

Recently, Dr. Ji Hailong, Director of the Orthopedic Department at Cangzhou No. 2 Hospital (East Campus), successfully performed a unicompartmental knee revision surgery. The goal was to minimize bone loss during the removal of the femoral and tibial implants. The initial SKII system allows for the use of augments and extension rods, making it suitable for unicompartmental revision. The patient has shown good postoperative recovery.

Case Details:

· Chief Complaint: Left knee pain with limited mobility for 3 days.

· History of Present Illness: The patient experienced left knee pain and restricted flexion extension 3 days ago without any obvious cause. X-rays revealed poor alignment following a previous unicompartmental knee replacement, with the spacer dislocated posteriorly. After outpatient evaluation, the patient was admitted with a diagnosis of “postoperative pain following left knee replacement.”

· Past Medical History: The patient had a left unicompartmental knee replacement in October 2018, with good postoperative recovery. The patient denies a history of chronic conditions such as diabetes, hypertension, or coronary heart disease, as well as any history of infectious diseases like hepatitis, tuberculosis, typhoid fever, or malaria. There is no history of trauma or blood transfusion, and the patient received all necessary vaccinations on time. The patient also denies any drug or food allergies.

· SKII PS+

1. The smooth intercondylar groove design and equal resection amount reduce post-wear and impingement during flexion.

2. Depending on the condition of the patient's medial and lateral collateral ligaments, the system allows for flexible intraoperative switching from PS to PS+.
