“…An understanding of the pathophysiology of the osseous tissue around implants contributes—together with the development of the chemistry of plastics and metallurgy, materials science and technology and tribology—to continuous upgrading of implanted artificial joints to improve the outcomes of endoprosthetic replacement, especially in young and physically active patients [1, 3, 10, 21]. …”

“…In general, it is a corrective surgical procedure designed to restore normal function in the limb, eliminate pain and allow the patient unaided, effective mobility [7, 8]. The implant’s life span is one of the crucial problems in hip arthroplasty that depends on many factors, including the method of implant fixation in bone tissue, the type of joint articulation system used, the type of implant material and the option of implant surface finish with porous substances, facilitating the process of biological healing of the implant into bone tissue [9, 10]. The volume of microparticles, which are released from implant surfaces by friction during normal joint function, depends on the type of artificial joint surface finish [3, 11, 12].…”

PurposeThe goal of the study was to evaluate long-term results of hip arthroplasty in patients with ceramic-on-ceramic articulation.MethodsThe follow-up involved 220 primary total hip arthroplasty procedures (188 patients, 101 women and 87 men) after implantation of the Mittelmeier cementless hip endoprosthesis. The mean age of patients at surgery was 44.5 years and the mean follow-up was 19.6 years, with a minimum of 12.3 years. Dysplastic, idiopathic and post-traumatic coxarthrosis were the most frequent forms of degenerative hip changes. The Merle d’Aubigné and Postel classification, as modified by Charnley, was used for clinical evaluation.ResultsVery good results were obtained in 39.5 % of the patients, good results in 43.6 %, satisfactory results in 9.1 % and poor results in 7.8 %. Twelve-year survival for the whole prosthesis was 86.36 %, for the acetabulum 89.99 % and for the stem 91.36 %.ConclusionsLong-term results of hip arthroplasty using the Mittelmeier prosthesis are fairly encouraging with their low incidence of loosened prosthesis components after surgery.

“…With the press-fi t Autophor TM , clinical reports from the USA noted a major problem with painfully loose stems, amounting from 15 to 80% incidence (Miller, 1986;Mahoney, 1990;Ivory, 1994;Shih, 1994;Huo, 1996). Short-term revision rates varied from 2% (Miller, 1986) to more than 30% (Mahoney, 1990).…”

“…Despite many reports, [1][2][3][4][5][6][7] the design and materials most suitable for cementless total hip arthroplasty (THA) remain uncertain, and new clinical problems have emerged. Bone resorption in the proximal femur seems to result from stress shielding due to the stiffness of the stem and the firm distal fixation by bone ingrowth into a fully porous-coated long stem.…”

W e implanted 51 Metal-Cancellous Cementless Lübeck (MCCL) prostheses into 45 patients with dysplastic hips and followed 49 hips (96.1%) for five to nine years. One had needed revision for stem fracture and one for infection; the clinical outcome of the other 47 hips was assessed using the Merle d'Aubigné and Postel hip score. All hips were either excellent (63%) or good (37%). Three patients (6%) had mild thigh pain at six months, but this had settled within two years. Serial radiographs showed stable fixation with bone ingrowth in all hips, with increased density of the cancellous bone in contact with the implant and some trabecular ingrowth. There was early varus shift of the stem in one hip, but this stabilised in three months. Osteolysis of the femoral cortex was seen in one hip at seven years after surgery, and mild bone resorption due to stress shielding in 31 (63%). Acetabular bone grafting with autogenous bone from the femoral head gave successful support to the socket in 13 hips. The MCCL prosthesis gave satisfactory mid-term results in patients with osteoarthritis secondary to hip dysplasia.
