Các báo cáo gần đây nhất của hemiarthroplasty kim loại đã được cả hai được xuất bản vào năm 1985. Scott et al. báo cáo về 40 bệnh nhân với 44 arthroplasties McKeever unicompartmental theo dõi trong 5-13 năm (trung bình 8 năm). Tại cuối cùng, 70% của đầu gối được đánh giá là tốt hoặc rất tốt | 327 52 Chapter 52 Metallic Hemiarthroplasty of the Knee - . Scott .

Scott et al. reported on 40 patients with 44 unicompartmental McKeever arthroplasties followed up for 5-13 years average 8 years . At final follow-up 70 of the knees were rated as good or excellent 10 .Also in 1985 Emerson and Potter published the results of 61 unicompartmental McKeever arthroplasties in patients followed up for 2-13 years average 5 years with a similar number 72 rated as good or excellent 2 . Despite these results metallic hemiarthroplasty never became popular possibly because of the advent of cemented metal-to-plastic total knee arthroplasty with its better initial and long-term results. Current Role of Metallic Hemiarthroplasty Certain patients however may still qualify for metallic unicompartmental hemiarthroplasty as an alternative to high tibial osteotomy HTO or metal-to-plastic unicompartmental UKA or total knee arthroplasty TKA . Indications would include a young osteoarthritic patient with unicompartmental arthritis of either the medial or the lateral side in whom an osteotomy is contraindicated by early opposite compartment disease or poor range of motion and who is considered too young heavy or active for TKA. It is estimated that approximately 1 of osteo-arthritic patients would be candidates. Another relative indication involves a patient with a past history of sepsis at the knee joint because of the minimally invasive nature of metallic hemiarthroplasty. The senior author has continued to use McKeever hemiarthroplasty for highly selected patients over the past three decades. An unpublished series of 24 knees in O Fig. 52-3. This patient played ice hockey twice a week 11 years after undergoing bilateral McKeever hemiarthroplasty patients under the age of 60 years has shown that .
