Abstract:
Objective To evaluate the clinical outcome of tibial tubercle proximalization in the treatment of patients with severe habitual dislocation of patella (HDP).Methods Among 51 HDP patients treated surgically in our hospital between April 2010 and 2014,28 were eligible for retrospective evaluation.All patients underwent tibial tubercle proximalization and lateral structure release.Additional surgeries included medial patellofemoral ligament (MPFL)reconstruction and tibial tubercle medialization.Radiological and subjective evaluations were performed at 4th and 8th weeks after the operation,as well as 1 year and every year afterwards.Results Twenty-eight patients,with an average age of (27.2 ± 9.4)(ranging from 18 to 39)were followed up for a minimum of 2 years,the mean follow-up period being (26.4 ± 5.8)months (ranging from 24 to 36).It was found 17.2％ (5/29) patients of quadriceps weakness,6.9％ (2/29)of patellofemoral pain and 6.9％ (2/29)of stiffness.No redislocation was reported.Significant improvement was observed in all subjective evaluation scores.Conclusions For patients with severe HDP,tibial tubercle proximalization can achieve satisfactory results.
