PURPOSE: Was to determine the relationship between pre-operative SPECT and intra-operative assessments of tibio-femoral chondral changes. METHODS: One hundred cases had been selected on the following criteria: (1) marked Tc-99 m uptake on the medial compartment and (2) its normal uptake laterally. The cartilage macroscopic condition of tibio-femoral compartments were then recorded during the surgery. RESULTS: A total of 73% of Grade 0, 24% of Grade I, and 3% of Grade II chondral injuries were detected laterally; 100% of Grade IV chondral lesions were detected medially. Statistically very significant relationship was demonstrated between SPECT and the mcroscopic cartilage condition. CONCLUSIONS: SPECT bone scan provides very useful information regarding the degree of osteoarthritis in knee weight-bearing compartments for pre-operative planning.
