[Is gonarthrosis with varus deformity a clinical entity].

Studies were conducted in a group of patients with varose deformity. The present paper gives the results of indicidual bone metabolism studies conducted on 663 healthy controls and patients with articular disease without genu varum or with varose deformity. In subjects with genu varum intravenous administration of calcium causes the urinary elimination of hydroxyproline and nitrogen to fall. Among the groups under investigation this group of patients excretes the least amount of urine, has a relatively low calciuria and shows the highest retention rate of intravenously administered calcium. Patients with gonarthrosis associated to varose deformity excrete, a day after intravenous administration of calcium, the relatively least amounts of phosphorus, as compared to the healthy controls and other degenerative joint diseases without genu varum. Although the retention of intravenous calcium in the studied group resembles that seen in the process of generalized osteomalacia, no coinciding signs of osteomalacia c ould be found in subjects with gonarthrosis and varose deformity. X-ray examination of patients with genu varum revealed more marked changes in the bone structure, namely sclerosis, necrosis and osteophytes of shapes and sizes other than in gonarthrosis without varose deformity. Epidemiological analysis of 30 patients showed 83.3% of patients to have overweight type I to III according to the Broca formula. Pains in the knee joints started appearing at the mean age of 50 years. A large part of the patients showed the presence of serious varicose syndrome and relapsing phlebitis of the lower limbs. Although the clinical and X-ray pictures make it possible to conisder a larger amount of disease types, we assume that gonarthrosis with varose deformity may be regarded as an isolated clinical entity which refers primarily to a localized bone process.

[Clinico-statistical studies of the tibial varism frequent among the school population of the Chiavenna valley and its relation to varus arthropathy of the knee in adults].

384 adolescents in Chiavenna schools were examined in a study of the considerable incidence of tibia vara, seen as a first step towards the patterns of varizing arthrosic deformation of the knee in adults of the same zone; at the same time indications on prophylactic-preventive measures in the field of scholastic and sport medicine were given.

Tibial osteotomy for the treatment of varus gonarthrosis. Survival and failure analysis to twenty-two years.

BACKGROUND: The purpose of this retrospective study was to assess the long-term results after the treatment of medial compartment gonarthrosis with a proximal tibial osteotomy to determine whether various clinical and radiographic factors relate to the outcome. METHODS: From 1972 to 1990, seventy-six valgus-producing high tibial osteotomies were performed in sixty-six patients with medial compartment gonarthrosis. Stabilization was achieved with use of a plate on the lateral side of the proximal part of the tibia and a figure-of-eight wire on the medial side. The mean age of the patients at the time of surgery was sixty-nine years, and the mean duration of follow-up was 10.8 years. The factors that were analyzed included postoperative valgus alignment; the age, gender, and weight of the patient; preoperative Ahlbäck radiographic grade; adverse events; Workers' Compensation status; and public liability. Survivorship outcome end points were conversion to arthroplasty, a Hospital for Special Surgery knee score of <70 points, and patient dissatisfaction with the procedure. RESULTS: Ten-year survival, according to the life-table method, was 74%, 70%, and 65% with conversion to arthroplasty, a Hospital for Special Surgery knee score of <70 points, and patient dissatisfaction, respectively, as the end points. Radiographic valgus alignment that ranged between 8 degrees and 16 degrees at one year after the osteotomy had the most significant positive effect on survivorship for all end points (p < 0.01) compared with the other parameters. Complications occurred in sixteen (21%) of the seventy-six procedures, and they had a significant effect on survival, with all three end points (p < 0.05). CONCLUSIONS: We found that survival at ten years was 90% (95% confidence interval, 80% to 99%) when the radiographic valgus angle at one year was between 8 degrees and 16 degrees with arthroplasty as the end point. We believe that there is a role for tibial osteotomy, as an alternative to total knee arthroplasty, in patients who are less than sixty years old. LEVEL OF EVIDENCE: Therapeutic study, Level III-2 (retrospective cohort study). See Instructions to Authors for a complete description of levels of evidence.
