Goal : Presentation of failures and complications of ACL reconstruction

Method: We studied 356 patients (361 knees) aged 14 – 52 years who had ACL deficiency and were treated by reconstruction the period from 1-1-1997 to 31-12-2002. They have been operated by the same surgeon (S.P.) 7 days to 5 years after the initial injury by arthroscopy or/and miniarthrotomy using BPTB graft (284) and ST/G graft (77). All co-existing injuries were also treated simultaneously (72 tears of the medial meniscus, 35 tears of the lateral meniscus, 37 tears of the medial and lateral menisci, 18 traumatic lesions of the articular cartilage, 3 posterolateral instabilities) by 42 meniscal repairs, 124 meniscectomies, 2 mosaicplasty, 16 drilling of the sub-chondral bone and 3 posterolateral reconstruction.

Results: Intraoperative: 3 patella fractures during BPTB harvesting, 3 breaking of bioabsorbable femoral screw, 2 non satisfactory BPTB graft fixation at the femoral tunnel, 1 asymptomatic exit of the screw at the back of the femur. Postoperative: 3 temporary apraxies of the peroneal nerve, 10 superficial and 3 deep infections, 15 reruptures or elongations of the graft, 18 with loss of extension < 10°, 5 with loss of extension > 10°, 2 with persistent hydrarthrosis after the 2nd postoperative month, 22 with anterior knee pain after BPTB harvesting, 3 with keloid, 1 with an acute korner at the graft harvesting site at the tibia, high percentage had weekness of the quadriceps mechanism and sensory abnormalities of the anterior side of the knee.

Conclusions: ACL reconstruction is a treatment with failures and complications that require axperience, knowledge and good instrumentation
