Abstract:Twenty-one osteoarthritic knees with an average varus angulation of 13 degrees were followed up for 7-10 years after resurfacing with the Marmor compartmental knee arthroplasty. There were 14 unicompartmental and 7 bicompartmental replacements, a total of 28 implants. The knees were assessed clinically according to the Hospital for Special Surgery knee rating scale. At the latest follow-up, 19 of these cases were still excellent or good. None of the knees had been corrected by more than the tightness of the li… Show more
The presented results indicate that the functional deficits may be caused by preoperative deficits and are not only due to the operation. It can be supposed that the gastrocnemius is more important because of the high correlation with the clinical results. The value of pre- and postoperative rehabilitation programs to prevent postoperative functional deficits can be concluded.

Forty‐four medial Marmor unicompartment knee arthroplasties were performed at the Hutt Hospital from 1976 to 1983 on 35 patients. Seventy‐five per cent were rated as excellent or good, using the Hospital for Special Surgery Knee Rating System. Four arthroplasties were revised at an average of 6 years (range: 2–8). two for late degenerative change in the lateral Compartment, one for malposition and one for loosening. There was one late deep infection requiring an arthrodesis at 2 years.
It is concluded that medial compartment knee arthroplasty provides satisfactory treatment in the elderly patient, although attention must be directed to technical aspects and patient selection, to afford long‐term success.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
