A five year follow-up of 605 cases of the MCCL (metal-cancellous cementless Lübeck) total hip prosthesis.

The porous surface of the MCCL prosthesis macroscopically resembles spongy bone, with a porous depth of up to 10 mm, the width of the pores measuring 1-2 mm, with reticular spaces forming an intercommunicating system. The superficial porous surface and the implant stem are combined in a single structure. The standard prosthesis is made up of four components; an acetabulum in cobalt-chrome-molybdenum alloy, an interposed layer of polyethylene, a ceramic head and a stem in cobalt-chrome-molybdenum alloy, the shape of which is anatomically matched to the proximal femur. What emerges from the present study is the possibility of using right and left stems, each available in six sizes. The ceramic head may be attached to the neck of the femoral stem, which may be long, average, or short. An "extra-long" metal head is also available.

[Transtrochanteric rotational osteotomy for idiopathic avascular necrosis of the femoral head (author's transl)].

Sugioka's transtrochanteric rotational osteotomy has turned out to be a new approach to the treatment of avascular necrosis of the femoral head in adults. It permits to displace necrotic bone outside the load area, as the rotation is performed in a range of 90 degree. Due to the anatomy of the pesterior region of the hip and the operative technique which takes special care of blood supply of the femoral head, vascular lesion, though quite conceivable because of the excessive rotation, does not occur. Sugioka's osteosynthesis by crossed screws has been performed successfully in Japanese. It cannot be recommended for surgery in white race people because of essentially different proportions of the length of extremities. So it does not provide early mobilisation and load bearing of white people treated in that way. This paper presents an essential modification on Sugioka's osteotomy. It modifies both the method of osteotomy and the osteosynthesis using a specially designed instrument. This modification eliminates the disadvantage of the originally described osteosynthesis, seems to improve blood supply of the rotated femoral head and facilitates the surgical procedure as well.

[Retropatellar facet replacement using the McKeever patellar prosthesis (author's transl)].

110 knees were evaluated after retropatellar facet replacement (McKeever). In 105 of these cases high tibial osteotomy has been additionally performed. Indication and operative technique are discussed in details. The evaluation of the pre- and postoperative status bases upon an observation period of 1--7 years and concerns the criteria of pain, movability of the joint and ability to walk. Due to the magnitudes of compressive forces in the patella joint during flexed-knee stance, the position of the patella is considered to be essential for the result of this surgical treatment.

[Experience on Guepar-hinge-prosthesis (author's transl)].

Total replacement of the knee joint by the G.U.E.P.A.R. hinge prosthesis has been performed in 72 patients suffering from severe gonarthrosis combined with ligamentous instability. Follow-up examination over a period of 1/2-5 years were made in 65 cases considering pre- and postoperative findings (pain, range of motion, ability to walk). This paper reports on problems of joint replacement surgery especially on details of operative technique to restore free gliding of the patella and muscular force as well. The G.U.E.P.A.R hinge posthesis has given good or excellent results in the great majority of cases.
