yes
In order to provoke the patellar reflex one must strike the patellar tendon with a tendon hammer (and only a tendon hammer, striking with an ordinary hammer is ill-advised). In other words, strike the region immediately below the patella.
you can observe a calcaneal reflex by striking the calcaneal tendon with the blunt side of a rubber hammer the calcaneal tendon is right above the heal on the backside of the foot, you can feel it easily

ReflExes are normal..it's not CNS ,it come out from PNS
When something like a hot object touches your hand, your receptors send impulses down the sensory neurone which then takes the impulses to the relay neurone (co-ordinator) which then sends the impulses to the motor neurone which goes in the opposite direction to an effector organ. This then reflexes your hand away from the hot object.
The test that makes use of a special hammer is the reflex hammer test. It is used to check the reflexes in various parts of the body by tapping the tendon with the hammer to observe the muscle's response.
no you should not strike the joint ,but as the name suggest we should strike the tendon
In order to provoke the patellar reflex one must strike the patellar tendon with a tendon hammer (and only a tendon hammer, striking with an ordinary hammer is ill-advised). In other words, strike the region immediately below the patella.
The test that makes use of a special hammer is the neurological examination test known as the reflex hammer test. This test is used to assess deep tendon reflexes by tapping on specific areas on the body with the hammer.
The proper name for the hammer a doctor uses to test your reflex is just "reflex hammer". It is a medical instrument used by physicians to test deep tendon reflexes and is an important part of a neurological physical examination.
The reflex hammer is used to check a person's reflex reponses. It is intended for testing tendon reflexes by striking the tendons. The reflex hammer is held by the handle, particularly close to the end oposite the head, with the head resting on the tendon which you intend to test. Make sure that the head is correctly lined up relative to the tendon. The hammer should be held against the tendon for some time such that the person being tested does not know when to expect the reflex. The hammer is now swung back and "bounced" off the tendon. It is important to make sure the hammer has a great velocity at the moment of impact (but don't use too much force to avoid hurting the tendon) and that it bounces off the tendon, rather than staying in contact with it. The action should be very brisk. It is usually completed in about a second.
DTR stands for Deep Tendon Reflexes.Deep Tendon ReflexesOne expansion for the medical abbreviation "DTR" is "deep tendon reflexes."Deep Tendon Reflex.
Reflex hammer is used to check tendon reflex of the patellar tendon at the level of the knee. Arthroscopy is used to check the knee, internally.
The instrument used by a doctor to test knee reflex is a reflex hammer. The doctor will tap the patellar tendon just below the kneecap with the reflex hammer to elicit a reflex response, which helps assess the function of the nerves and spinal cord.
Reflex hamers are medical instrumets and are only used for medical applications. The makker is mot commonly used to test deep tendon reflexes.

The paper of Jamieson et al. on this subject concludes the following: There is no plausible reason that TKA should affect the patellar tendon reflex. Despite this, in clinical practice TKA is often thought to be responsible for absent patellar tendon reflexes. This study supports the hypothesis that there is no effect of TKA on patellar tendon reflexes. Jamieson R, Flynn J, Love D. Does total knee arthroplasty affect the patellar tendon reflex?
