Purpose: A lot of surgical techniques were tried to correct extension lag of distal interphalangeal joint. Spiral oblique retinacular ligament reconstruction is the one of correction techniques. Methods: From January 2004 to January 2005, a total of 13 extension lag of distal interphalangeal joint corrections were performed using spiral oblique retinacular ligament reconstruction for 11 patients. After dorsal incision exposing from base of distal phalanx to proximal phalanx, the new ligament(half of lateral band or graft tendon) lies distally at the dorsum of the distal phalanx and passes volarly and proximally along the side of the middle phalanx and anterior and obliquely across the front of the proximal interphalangeal joint to the opposite side of the digit at the proximal phalanx. Results: 5 of 6 mallet finger deformities and 7 swan neck deformities were corrected, which were both extension lag of distal interphalangeal joint and hyperextension of proximal interphalangeal joint. Conclusion: As a result, spiral oblique retinacular ligament reconstruction is an effective and recommendable method for correction of mallet finger deformity and swan neck deformity.

Multiple ligament knee injury is defined as rupture to at least two of the four major knee ligament structures. Three or four knee ligament injury results in knee dislocation as complete disruption of the integrity of the tibiofemoral articulation. In multiple ligament knee injury, vascular and neurologic assessment should be performed meticulously and systematically. Emergency surgery should be needed if arterial injury is suspected. Surgical treatment rather than conservative management should be done and early surgery might be better than delayed surgery. Reconstruction of ACL and PCL, repair or reconstruction of MCL, and reconstruction of posterolateral corner are recommended, although many debates have occurred. Multiple ligament knee injury requires more aggressive management than single ligament knee injury.

The incidence of anterior cruciate ligament tears is increasing as a result of the increasing participation of individuals of all ages in high-risk sports. Endoscopic anterior cruciate ligament reconstruction using autogenous central third bone-patellar tendon-bone graft is the most commonly used method. With regard to BPTB graft as the go]d standard in ACL reconstruction, there are no data that refute this claim to date. Author reviewed the biomechanical properties, donor site morbidity and selection of the bone-patellar tendon-bone graft and described the surgical technique of endoscopic ACL reconstruction using BPTB autograft.

Optimal treatment of the torn posterior cruciate ligament (PCL) remains controversial. The type of tibial fixation (transtibial vs inlay), the femoral tunnel position within the femoral footprint (central, eccentric or isometric), and the number of bundles in the reconstruction (single-bundle vs double-bundle) are controversial issues. The PCL has a better chance of spontaneously healing than the anterior cruciate ligament (ACL) because of a rich blood supply (near the branch of the middle genicular artery) and coverage with a thicker synovium. In general, for easier passage of the graft and full visualization of the original ligament attachment site during the precise positioning of the tunnel, the remaining PCL fibers are usually debrided during reconstruction. However, the remaining remnant structures would significantly contribute to the posterior stability of the knee joint, the healing of the graft, preserving proprioceptive function of the mechanoreceptors in the PCL. Double bundle PCL reconstruction may result in some surgical complications because of increased complexity of making tunnel. Therefore, single bundle PCL reconstruction with remnant preservation seems to be an effective procedure.

Open kinetic chain exercise has lost favour in rehabilitation after cruciate ligament reconstruction due to concerns that this exercise is harmful to the graft and will be less effective in improving function. Therefore rehabilitation has focused over the past decade on closed kinetic chain exercise. Open kinetic chain and closed kinetic chain exercises were compared for their effects on proprioception, muscle strength and knee instability in the early period of cruciate ligament reconstruction rehabilitation. The study subjects were 14 patients in 28weeks from cruciate reconstruction surgery(11 male, 3 female; mean age = 44.36 years). Closed kinetic chain exercise group used ball, balance pad and air cushion, to perform weightbearing exercises and the open kinetic chain exercise group used elastic rope and N-K table, to perform non-weightbearing exercises. Between tests, subjects trained 5 times per week for 2 weeks. Statistical analysis was by Wilcoxon signed rank test and Mann Whitney U test. In result, this study shows that both open and closed kinetic chain exercise programs lead to an improved muscle strength and Lysholm score. But there was no improvement in proprioception at both exercises. Closed versus open kinetic chain exercise in early period of rehabilitation after cruciate ligament reconstruction surgery do not differ in their effects on knee proprioception, muscle strength and instability. But the effect of closed kinetic chain exercises was showed more improvement than open kinetic chain exercises between pre-post exercises. Therefore further study is required to assess effect of both groups in more long period.

Puropse: To evaluate the outcome of arthroscopic posterior cruciate ligament (PCL) reconstruction using fresh-frozen achilles allograft tendon with preservation of ligament remnant or elongated ligament. Materials and Methods: From October 2004 to March 2010, we performed PCL reconstruction with Achilles tendon allografts in 22 complete rupture patients. Mean age was 31.5 years. 14 cases were male and 8 cases were female. Average follow-up period was 3 years and 7 months, range from 1 year to 6 years and 4 months. Subjective and objective parameters were utilized in analyses, such as the mean range of motion, post. drawer test, Lysholm knee score, Tegner activity score, IKDC score, and second look arthroscopic examination. Results: Postoperative Lysholm knee score, IKDC scores, Tegner activity scale, and posterior displacement by the Telos stress test demonstrated statistically significant improvement compared to the preoperative state. Conclusion: Arthroscopic PCL reconstruction using fresh-frozen achilles allograft tendon with preservation of ligament remnant showed good clinical results and posterior stability.

The complication caused by a bioabsorbable interference screw is rare after anterior cruciate ligament reconstruction. We report a case of delayed inflammatory reaction at the tibial tunnel and femoral tunnel where the graft tendon had been fixed with a bioabsorbable interference screw ($Bioscrew^{(R)}$) for anterior cruciate ligament reconstruction using bone-patellar tendon-bone autograft.

The complication caused by a bioabsorbable interference screw composed of Poly-L-Lactic-Acid is rare after anterior cruciate ligament (ACL) reconstruction. We reported a case of a pretibial ganglion at the orifice of the tibial tunnel where the graft tendon had been fixed with a bioabsorbable interference screw $(Bioscrew^{\circledR})$ for ACL reconstruction using autogenous hamstring tendon. The patient was underwent ganglion excision and interference screw removal.

Various surgical techniques has been advocated for reconstruction of anterior cruciate ligament using the bone-patella tendon-bone graft. Recently endoscopic technique provides good clinical results, with minimal skin incision, accurate positioning of the graft to the femoral tunnel, and decreasing wear rate of the graft. But the graft-tunnel mismatch remains problematic in endoscopic technique. The purpose of this paper is to described causes of the graft-tunnel mismatch and to provide important steps to prevent or minimize the graft-runnel mismatch following anterior cruciate ligament while using the endoscopic technique. Our guideline for prevention of the graft-tunnel mismatch are as follows: (1) The tunnel should he positioned closely to isometric point as much as possible. (2) Anterior placement of the tunnel should be avoided. (3) The change of graft length should be within 2mm between flexion and extension position.
