It is becoming increasingly important for the radiologist to evaluate the appearance and outcome of cartilage repair procedures. MR imaging is currently the best method for such evaluation but it is necessary to use cartilage-specific sequences and to modify those sequences when necessary to minimize artifacts from retained metal within the joint. This article reviews the surgical technique of the more commonly performed cartilage repair procedures, currently recommended techniques for the MR imaging evaluation of articular cartilage and cartilage repair procedures, and the MR imaging appearance of cartilage repair procedures and of the most frequently encountered complications following such procedures.

In 1890, the German surgeon T. Gluck was the first to implant an ivory arthroplasty into a wrist which was being destroyed by tuberculosis. The finger joints were first replaced with endoprostheses in 1940 by Burman. Indications for the procedure are degenerative, posttraumatic or arthritis related destruction of the joints of the hand.Nowadays, several more or less comparable prosthetic designs are available. The replacement of single bones of the wrist has not been of lasting success. Occasionally, an indication for arthroplasty of the trapezium-metacarpal joint of the thumb may exist. The metacarpophalangeal joint of the thumb should, in our experience, be fused when the need arises. Up until the present, the silastic spacer of Swanson for the metacarpophalangeal and proximal interphalangeal joints has not shown any substantial development, although a variety of designs have been introduced. Questions related to the complicated biomechanics of these articulations in combination with problems concerning the material to be used, intraosseous fixation, the articulation of the prosthesis components and the design of the stems have not yet been solved convincingly. The Swanson spacers in mid- to long-term follow-ups show little active range of motion, although the subjective patient satisfaction is very high and the potential for removal at its best. We do not see an indication for arthroplasty in the distal interphalangeal finger joints.
