In brief: Often not a tendon

Pain on the inside of the knee can result from the medial retinaculum (ligament that holds kneecap in place), arthritis, meniscal (cartilage) tears, pes anserine bursitis and/or stress to the medial collateral ligament.
Tendinitis on the inside of the knee occurs, but less commonly than those other conditions listed above. Consider a physician eval. Along with a gait analysis and footwear update.
