[Weber fibular ligament-plasty with plantar tendon with Segesser modification].
Ankle joint injuries are one of the most frequently diagnosed sports injuries. In our clinic we observed between 1981-92 18% ankle joint injuries in 11.350 patients. The acute injury was generally handled conservatively by functional treatment with a special shoe; only comminute injuries like fractures, luxations or tendon injuries would lead to the decision to perform surgery. The ratio of acutely performed surgery compared to late surgery was decreasing: 1981 1:3, compared to 1992 1:50. Reconstructive surgery of the lateral ligament complex is indicated under the following conditions: patient suffering from recurrent trauma and feeling of instability and/ or in case of comminuted overuse injuries caused by instability like the entrapment of the tibial nerve in the tarsal tunnel, achilodynia caused by instability of the rearfoot or luxation of the peroneal tendons. Reconstruction of the lateral ligaments of the ankle should be done anatomically, operations with effect of tenodesis should be avoided. ⋯ 443 (76%) out of 584 operated patients were followed at least one year after OP. Working ability: 19% (group 1)/25% (group 2) of the patients after two weeks, 31/42% after 2-4 weeks and 79/88% after 4-6 weeks. Full sports activity to previous sport 8/17% after 4-6 weeks, 26/38% after 6-8 weeks, 65/70% after 8-12 weeks. The group 2 achieved full sports activity and working ability on average two weeks before the patients of group one. Personal evaluation: 88/90% felt their ankle joint to be more stable postoperatively, 10/9% as stable as before and 2/1% described it as less stable. Clinical evaluation: The modified Benedetto score showed in 76/81% very good results, in 9/7% good and 13/8% bad results. In conclusion the described reconstruction of the fibular ligaments without damaging the active stabilizing muscles is a valid technique. The reconstruction of the calcaneofibular ligament improved the long term results of surgery. The functional postoperative rehabilitation (special shoe and night brace) does shorten the time for the patients working ability as well as the return to full sports activity. The long term results on the other hand appeared to be similar for both groups. The advantage of our technique using the plantaris tendon as a graft. The use of autograft material having the same tensile strength as the original ligaments anatomically reconstructed. Surgery with tenodesis effects should be abandoned. The good results occurring while performing late surgery leave the chance for primary conservative treatment of lateral ligament injuries.
