Background: The patellar tendon length can change following surgical treatment of lower pole patella fractures. The commonly used parameters among many to assess the changes are Insall-Salvati ratio and Black-burne peel index. The changes in the parameters would have implication on the patella-femoral biomechanics. The clinical and radiological changes may be dependent on one another. Multiple complications are present in each of the technique used to fix such fractures. The study was undertaken to evaluate the short term clinical and radiological results of alteration in the patellar tendon length after trans-osseous fixation with pull through sutures of lower pole patella fractures. 30 patients were evaluated clinically with Kujala score, Insall-Salvati ratio and Black-burne peel index. The patients had a final mean range of movement 152 degrees (mean 134-170 degrees). The mean time required to recover full range of motion following discontinuation of immobilizer was 18 weeks (range 15.5 to 22 weeks). The Kujala score was 93 after 1year and the changes in the patellar tendon length was present in majority but was not statistically significant. The conclusion was derived that although the changes in patella tendon length after surgical treatment is common but the short term clinical implications are not evident.
