Excisional arthroplasty for patellar loosening in total knee arthroplasty.

Four thousand two hundred eighty-seven cases of Anatomic Graduated Components total knee replacements with a cemented, single-peg, all-polyethylene patellar component were performed at our institution over the past 15 years. One hundred eighty cases of patellar component loosening were found. Eleven knees (0.3%) in 11 patients required isolated patellar component reoperation. In all cases, the patellar component was excised and not reimplanted. The average follow-up for the 11 patients was 2.2 years. Five had a complete minimum follow-up of 2 years following reoperation. Pain and function were improved. Complications included infection in 3 knees and extensor lag in 1 knee. Because of the complication rate associated with isolated patellar component excision caused by a loose patellar component, we recommend surgical removal of the patellar component only in cases of severe pain and/or prominence of the component.

Different surgical options for monocompartmental osteoarthritis of the knee: high tibial osteotomy versus unicompartmental knee arthroplasty versus total knee arthroplasty: indications, techniques, results, and controversies.

The decision of what procedure to perform for the treatment of monocompartmental osteoarthritis of the knee when nonsurgical treatment methods fail remains controversial. Recent advances using osteotomy, unicompartmental knee replacement, and total knee replacement have been reported. For example, there are new concepts for performing high tibial osteotomies rather than the traditional Coventry method. Many techniques now involve osteotomies below the tibial tubercle. Unicompartmental knee replacement can be done using a standard approach, but less invasive approaches exist, along with minimally invasive approaches for total knee replacement, rather than the standard large incision, that promote decreased soft-tissue destruction.
