| Abstract: | BACKGROUND:Adult recurrent patellar dislocation is commonly treated with bone transplantation as it will not consider the damage to the epiphysis, but it is not suitable for child recurrent patellar dislocation, and most scholars choose the soft tissue transplantation to treat child recurrent patellar dislocation.
OBJECTIVE:To retrospectively evaluate the clinical treatment effect of soft tissue transplantation for the treatment of child recurrent patellar dislocation with unclosed epiphysis in 22 cases.
METHODS:Twenty-two patients (29 knees) with children recurrent patellar dislocation selected from the Department of Joint Surgery, Shanghai Changzheng Hospital during May 2006 and April 2009 were retrospectively analyzed. The patients were treated with soft tissue transplantation, and followed-up at 3 and 6 weeks, 3 months and 1 year after transplantation, and every year thereafter. The patellar stability, subjective symptoms and knee rehabilitation were evaluated.
RESULTS AND CONCLUSION:Among the 22 patients, one case had recurrent patellar dislocation, one case had medial patellar dislocation, and the other cases obtained satisfactory effects. The subjective scoring of knee function before and after the soft tissue transplantation were 46.99±5.91 and 94.40±9.70, respectively (P < 0.01), comprehensive Lysholm knee function score before and after soft tissue transplantation were (44.37±4.49) and (90.10±11.00) respectively (P < 0.01), and the patella-tackle congruence angle was changed from preoperative (16.27±6.74)° to postoperative (5.33±8.78)° (P< 0.01), the lateral patellofemoral angle was changed from preoperative (-1.92±7.64)° to postoperative (11.95±3.99)° (P < 0.01). Soft tissue transplantation for the treatment of child recurrent patellar dislocation with unclosed epiphysis has the advantages of easy to operation, strong operability and satisfactory effect, and it is beneficial to relief symptoms and to improve knee function. |
