<human>: Hi I am 6 month post op TKR including a patella replacement as I did not have one pre op and 12 month post op having had my femur rotation so 35 deg to correct a previous surgery to fix 5 breaks of femur 40 years ago. I am now having quite severe knee cap tendon pain as well as an electric shock type pain in my shin when I fully bend my new knee. Could you please advise if this is normal, and will it settle down. My fear is that I will be left like this
<bot>: Hi, Electric shock like pain in knee is associated with the knee tendon (qua Chat Doctor.  It is common post TKR if the rehab is not done properly I.e. post-operative you need to exercise your muscles to get used to the new biomechanics. Also, as you said you had a rotation in your femur which can add to the muscle overuse injury (faulty biomechanics of knee). For this it would be good if you consult a physical therapist for a good rehab program. Also till then you can do the following exercises (can search with the terms). You can use 500 GMS weight/Theravada knee press, knee flexors/Censorship rotators. Stretching of tensor fascia late Hip flexion/extension/abduction/adduction/rotation. Application of hot packs will help in muscle relaxation. Hope this helps. Let me know if I can assist you further.
