The interference screw gets away from that problem discount dramamine 50mg otc, but has poor performance in cyclic load. The Intraﬁx (Mitek) device uses the interference screw ﬁxation principle, but increases both the ultimate load to failure and the cyclic load performance (Table 5. Considerations The most important consideration in ACL reconstruction is that the tunnels are put in the correct position. After this, the ﬁxation of the graft is the next most important factor in a satisfactory clinical outcome.

Graft Selection sions, physicians may need to have available another type of ﬁxation to deal with hardware and tunnel expansion. Tendon-to-Bone Healing Studies have shown that it takes at least 8 to 12 weeks for soft tissue to heal to bone, as compared to 6 weeks for bone-to-bone healing with the patellar tendon graft. Recent studies have shown that the compression of the tendon in the tunnel with a screw speeds the time of healing, similar to internal compression in bone healing. Donor Site Morbidity In 1982, Lipscomb found that after harvest of the semitendinosus only the strength of the hamstrings was 102% and after harvest of both the strength was 98%. Recently, it has been shown that the internal rota- tion strength is decreased after the harvest of the semitendinosus. The patellofemoral pain incidence has been reported by Aligetti to be 3 to 21% after semitendinosus reconstruction. Early Rehabilitation Prospective randomized studies by Aligetti and Marder have shown that with early and aggressive rehabilitation, there was no difference between the semitendinosus and patellar tendon grafts in stability or ﬁnal knee rating.

Hamstring Graft Reconstruction Techniques Step 2: The Reduction of the “Handle” First generic 50 mg dramamine with mastercard, the physician should reduce the displaced fragment (Fig. The author uses the blunt arthroscope trocar to push the meniscus back into place under the condyle. The hybrid repair of sutures anteriorly and ﬁxators in the difﬁcult to reach posterior segment is acceptable. The use of inside out sutures requires the use of a separate posterior inci- sion to retrieve the sutures and tie them over the capsule. The incision avoids injury to the saphenous nerve on the medial side and the pe- roneal nerve on the lateral side. Step 3: Preparing and Repairing the Meniscus The tear should be initially probed to determine if it is suitable for repair. The edges of the tear should be débrided of ﬁbrous tissue with a rasp or a small shaver (Fig. Pavlovich has described the technique of stimula- tion of the meniscal synovial border with electrocautery. The principle is to lightly “burn” the synovium to stimulate a healing response. The monopolar electrode can be used to stimulate the synovium at the tear. Zhang demonstrated that the meniscus and the rim may be trephinated to produce vascular access channels. The sutures and the bioabsorbable devices must be placed accurately to reduce the tear and hold it until it is healed. The common approach with a large bucket- handle tear is to use sutures in the middle segment to reduce and hold the bucket tear and then use the bioabsorbable devices in the difﬁcult- to-access posterior horn region. Step 4: The Posteromedial Incision The next step is to create a posteromedial or posterolateral incision (Fig. On the medial side, with the knee at 90° of ﬂexion, this technique is a 3 to 6cm incision placed just posterior to the medial collateral lig- 76 6.
