    Abstract:
    PURPOSE: This study highlights the pattern of presentation, treatment, early functional outcome, and complications observed in the management of chronic patellar tendon ruptures using our preferred technique of autogenous semitendinosus graft reconstruction. METHODS: This was a retrospective case series involving consecutive patients who underwent patellar tendon reconstruction and met the inclusion criteria. The outcome measures were determined by the post-operative knee range of motion (R.O.M), the post-operative International Knee Documentation Committee (IKDC) score, and pattern of post-operative complications. RESULTS: Nine patients were included in this case series. The mean age of the patients was 35.4 ± 6.8 years (range 27-44 years). Trauma to the knee accounted for majority of the cases (62.5%). Six (66.7%) of the nine patients suffered a patellar tendon rupture from contact injury during sporting activities. The mean length of time from injury to presentation was 20.5 ± 11.2 weeks (range 6-69.5 weeks). Normal knee function in a case (11.1%), nearly normal knee function in 7 cases (77.8%), and abnormal knee function in a case (11.1%) were recorded as a measure of outcome of surgery. The mean post-operative IKDC score was 70.0 ± 6.1 (range 55-77), which was higher than the mean pre-operative score of 26.4 ± 5.1 (range 18-32). The post-operative knee R.O.M averaged 97.2 ± 16.2° (range 70-120°) with a single case with a 10° extension lag noted. CONCLUSION: Normal to near-normal knee function was obtained with the treatment of chronic patellar tendon rupture in the majority of cases using autogenous semitendinosus graft for patellar tendon reconstruction in our series.
