The making of an artificial joint.
Reconstruction of a new and functioning joint from an ankylosed one; a plastic operation upon a joint.



an operation that restores function of a joint.

Indications for arthroplasty are ankyloses, improperly knitted intra-articular fractures, and deforming arthroses. Arthroplasty consists in disconnecting the joint extremities, modeling new joint surfaces, and placing between them layers of the patient’s tissue (skin or fascia). Caps of cartilage or fetal membrane (amnion) are also used. Preserved joint extremities (homohemijoints) or whole joints (homojoints) taken from corpses, artificial joint heads of plastic or metal (for example, the head of the femur in arthroplasty of the hip joint), and artificial joints (for example, metallic prostheses of the hip joint or of finger joints) are widely used. After the operation, prolonged functional treatment (therapeutic exercise, physiotherapy, and massage) is mandatory.

Interpositional Gap Arthroplasty was found highly effective and safe surgical management option for TMJ with acceptable immediate and long term outcome, particularly when temporalis fascia or muscle and iliac crest grafts were used for adults and costochondral grafts with fascia interposition used for children.
The most frequently used procedures include Gap arthroplasty, interpositional arthroplasty, excision and joint reconstruction with grafts (autogenous and alloplastic), and total TMJ replacement with joint prosthesis.
Amongst the procedures used primarily for the relief of ankylosis, some researchers have advocated in favour of Gap arthroplasty whereas others have con- cluded that Interpositional arthroplasty is a better option.
