Arthroscopy is investigation of choice and preferred way of treatment.
All loose and overhanging pieces of cartilage must be removed back to a stable base. The base maybe drilled, abraded or microfractured to bleeding bone that presumably recruit-pluripotent stem cells to regenerate cartilage.
Osteochondral autograft transplant should be considered.

Answer - A., B., C., D., E.
Major indication(s) for arthroplasty A. Osteoarthritis of hip B. Ankylosis of elbow C. Ununited tibial fracture D. Ununited femoral neck fracture E. TB spine

Metal on metal articulation should be avoided in A. Osteonecrosis B. Young female C. Inflammatory arthritis D. Revision surgery
Answer-B. Young females
Metal on metal articulations are contraindicated in patients with established or impending renal failure and metal hypersensitivity. It should also be avoided in young women or women of child bearing age due to unknown effects of elevated levels of metal (cobalt and chromium) ions on fetus.
Aseptic loosening in cemented total hip replacement, occurs as a result of hypersensitivity response to A. Titanium debris B. High density polythene debris C. N. N-Dimethyltryptamine (DMT) D. Free radicals
Answer-B. High density polythene debris
Particles of metal(titanium, nickel, chromium), cement ( PMMA) and polythene all can produce periprosthetic osteolysis( aseptic loosening); but because they are most numerous polyethylene particles, it appears to be the major culprit.
