A Morphometric Study of Patella in Total Knee Replacement

T.K.A. is a safe and highly rewarding surgery in experienced hands. A lot of research is continuously been done to update our existing knowledge about the surgery and to give better outcomes. In the above study we have established that 100 % of females in the study group, because of their short stature was having patellar thickness less than or equal to 23mm and hence was not suited to undergo patellar replacement due to lack of small size patellar implant. About 56 % of the male population were also having patellar size less than or equal to 23mm and patellar resurfacement was not done in them too.The smallest available patellar implant in India is about 8 mm in size which is not suitable for Indian patient. Hence in this study we conclude that there is a need of better designed implants for Indian patients as the presently available implants are mainly designed for western population.In the study we also established that a positive correlation existed between the radiological findings and intra op measurement of patella.Hence, we can inform the patients priory about the tentative size of implant they will need and also whether or not they can undergo patellar resufacement.
