Background: Subchondral implants alter the stress distribution in the cancellous bone and induce damage to the overlying cartilage.
Methods: 100 consecutive cases of lateral tibial condyle fractures treated with osteosynthesis were selected. Two groups were established: group I. with 64 cases and metal removal within 12 months, and group II with 36 cases and metal removal after 12 months post operatively. After 5 years on follow up examination and X-ray evaluation the rate of arthrosis was assessed in both groups.
Results: In group II the rate of osteoarthrosis was significantly higher than in the group I.
Conclusions: Subchondraly placed metal implants in the lower extermity should be removed within 12 months post operatively.
