Longterm analysis of Sheehan total knee arthroplasty.

Sheehan total knee arthroplasty was carried out in 405 knees at two centres. The patients were followed up from two to eleven years. The clinical results were assessed, the complications documented and the influence of specific factors on the result was evaluated. The principal complications arose from the patella and the femorotibial articulation. The low rate of loosening and the achievement of satisfactory alignment lead the authors to support the concept of a long stem.

[On the usefulness of bone scintigraphy for detecting loosening of articular prostheses (author's transl)].

The most important complication of articular substitution is the loosening of the prostheses as a result of permanent overstraining, trauma, chemical or infectious noxae. The value of bone scintigraphy in the diagnosis of loosening of the endoprothesis was examined in 53 articular prostheses (49 hip joints and 4 knee joints). A pathological scan was evident in all cases where the prosthesis had become loose (18 cases), whereas a normal scan was found in 34 firmly positioned prostheses. A false positive scan occurred in one case of periarthritis. Bone scintigraphy can be employed as a means of diagnosing loosening of prostheses after a period of nine months following the operation; up to that time, enhancement can be due to the operation. A positive scan in case of loosening of the prosthesis is manifested earlier than radiological signs. For this reason, scintigraphy can be recommended as a routine examination method in pain after articular substitution surgery.

[Kates forefoot arthroplasty (author's transl)].

In a series of 93 forefoot arthroplasties (71 of them followed up), the majority of the cases showed good results of Kates' procedure. The most frequent sources of errors are inadequate treatment of the plantar skin and the formation of steps in the line of resection of the mid-tarsal bones. Rheumatic and degenerative forefoot deformities are equally well suited for this procedure. Forefoot deformities combined with pes equinus appear to be less suitable.
