Abstract — From Department of Orthopedic Surgery, Carolinas Medical Center, Charlotte, North Carolina Seventy-three consecutive unicompartimental knee arthroplasties (PKRs - [partial knee resurfacing] ) using a Marmor-style non-metal-backed cemented tibial component were perfomed from 1975 to 1990. Sixty-seven knees (58 patients) were evaluated with minimum 5 year follow-up (mean, 9.7 years; range 5-20 years). Knee rating and patient function were assessed using the updated Knee Society scoring system.Survivorship and functional outcome were not affected by body habitus, age, gender, or tibial component thickness. PKR's offers long term relief of symptoms and excellent knee function in a high percentage of carefully selected patients with single compartiment gonarthrosis. KEY WORDS: unicompartimental knee arthroplasty , gonarthrosis, obesity, long-term follow-up.
