[Resulted outcome of proximal and distal realignment in patients with patellar subluxation and dislocation]

Anterior knee pain is a common complaint in orthopedic patients, and patellar malalignment is a fragment cause of this alignment. Severe malalignment would result insubluxation and dislocation of patella: the result of surgical treatment with proximal and distal realignment [P/DR] for such pathology, performed in Sadoghee and Al-Zahra hospital [in Isfahan] from 1994 to 1999 is reported in this article. A retrospective study of 26 cases, 4 male and 22 female patients, with average age of 28 years. which had patellar instability and had undergone P/D-R during a five year period [1944-1999] in two of the hospital in Isfahan, was performed. These cases had all failed the initial conservative treatment. The cases were follow-up for a period of 3.5 years. Results of surgery were canalized in term of subjective relief of symptoms, and objective evaluation of quadriceps power, knee motion, as well as radiographic signs of knee degeneration, patellar subluxation, patella alta or patella infra. 30 knees had received the index operation - 16 [53%] right and 14 [47%] left side. The result of surgery was good in 28 [94%] and poor in 2 knees. 20 patients [71%] had normal radiographs, 5 cases [18%] had evidence of mild and 2 cases severe degeneration. Patellar intra was also observed in one knee. proximal and distal realignment surgery for cases that suffer from patellar instability and are non-responsive to conservative treatment is associated with high rate of success without serious complication

[ study of results of nova bontransplantation in treat meat of bone seases]

Bone grafts [Alograft. Autograft and synthetic bonegraft] are used to rapaire bone defects. According to several technical and medical problems. synthetic bone grafts [B.G] are perefered to others. Nova Bone is an ABG which in more available in Iran, now .So we conducted this study to evaluate it. 62 Patients with bone defects who needs bone graft during 1 year, under went Nova Bone graft. F/U data we analysed, according to graft failure and calcium formation. 6 patients out of 62 had been failed to form calcium after 20 weeks of F/U .[9.7%]. There were no other Complications [infection and noninfectious]. Using SBG [including Nova Bone] has been advocated recently due to several problems including Allografts and Autografts. Favorable results [90.3% calcium formation] in patients with Nova Bone grafts [alone or in combination with auto and Allograft] Propose the regular use of it for patients need bone grafts
