Patellar Transskeletal Traction for the Treatment of Chronic Patellar Pseudoarthrosis.

ABSTRACT: Patellar fractures, which constitute approximately 1% of bone lesions, may lead to severe impairment of the extensor mechanism. When conservative or surgical treatment fails, the patella may develop pseudoarthrosis. Neglect or delayed treatment of this type of injury may lead to significant diastasis between the patellar fragments. There is no consensus regarding the best treatment for such cases. This study is aimed at describing a rare case of patellar pseudoarthrosis in a patient who underwent two-step surgical treatment comprising transskeletal patellar traction followed by osteosynthesis with a tension band. A 17-year-old male patient presented with a left patellar fracture that resulted from a fall from a standing height 8 years ago. He did not undergo any type of surgical treatment during that time, but the fracture was immobilized for only 2 weeks. The two-step surgical treatment with transskeletal patellar traction and patellar osteosynthesis was performed and provided satisfactory functional clinical results in this patient. This two-step surgical treatment can be performed in cases similar to ours with satisfactory results.

Project description:Purpose: Whole body vibration (WBV) triggers anabolic responses in various tissues, including tendons, without requiring high force production. In this waitlist-controlled equivalence trial, we tested its clinical effectiveness as an alternative treatment for patellar tendinopathy against conventional heavy slow resistance training (HSR). Methods: Thirty-nine patients were randomized to either 3 months of WBV training (n = 13), HSR training (n = 11), or a waitlist control (WLC) group (n = 15). In a partly cross-over design, 14 patients of the WLC group were redistributed to one of the two intervention groups (5 in WBV, 9 in HSR). Pre- and post-intervention testing included pain assessments (VAS), functional limitations (VISA-P), knee extension strength and tendon morphological, mechanical and material properties. Follow-up measurements (VAS, VISA-P) were performed in the WBV and HSR groups 6 months after the intervention. Results: Comparisons with the WLC group revealed significant improvements in VISA-P and VAS scores after HSR (41%, p = 003; 54%, p = 0.005) and WBV (22%, p = 0.022; 56%, p = 0.031) training. These improvements continued until follow-up (HSR: 43%, 56%; WBV: 24%, 37%). Pre-post improvements in VAS scores were equivalent between WBV and HSR groups but inconclusive for the VISA-P score and all pre-test to follow up comparisons. The mid-tendon cross-sectional area was significantly reduced after WBV (-5.7%, p = 0.004) and HSR (-3.0%, p = 0.004) training compared to WLC although the equivalence test between interventions was inconclusive. Conclusion: Whole body vibration improved symptoms typically associated with patellar tendinopathy. This type of intervention is as effective as HSR against maximum pain, although equivalence could not be confirmed for other variables. The beneficial responses to WBV and HSR treatments persisted for 6 months after the end of the intervention.
