Stopień powikłań po 214 kolejnych zabiegach TTA stosowanych w terapii zerwania więzadła krzyżowego przedniego

Discussion

Using major complications to compare different surgical techniques is a valuable tool, because the rate is deduced from a simple „yes/no” answer. However, it is difficult to retrieve numbers from studies in which the complications were not defined as minor or major. Additionally, some postoperative problems such as meniscal problems were not re-operated, because the owners declined (3, 6). Tibial fractures are listed as complications in the study of Stauffer et al. (4). It is not known if all these fractures created the need for a revision surgery. A last point to criticize is the observation period. As seen in table 2, some complications occurred after the minimal observation time. The real complication rate might, therefore, be higher, as it is in all other studies as well.

The major complication rate of 7% after 214 TTAs is much lower than other major complication rates recently published (3, 8-10) and comparable to TPLO (2, 4, 6, 15) complication rates. Surgical experience seems to be an important factor when studying these rates. Since TPLO was introduced about 10 years earlier than TTA (1, 2), it seems obvious that surgeons feel much more comfortable with that technique. This hypothesis is further sustained by a report showing a high complication rate in a series of rather small TPLO numbers (7).

Even in the present study, the effect [...]
