OBJECTIVE@#To investigate the clinical effect of high tibial osteotomy combined with arthroscopic lateral retinacular release in the treatment of knee varus osteoarthritis.@*METHODS@#From October 2017 to April 2019, a retrospective analysis was performed on 43 patients with knee varus osteoarthritis and lateral patellar compression syndrome treated by high tibial osteotomy combined with arthroscopic lateral retinacular release. There were 15 males and 28 females, aged 53 to 72(62.05±5.17) years. The visual analogue scale(VAS), Lysholm, and the knee range of motion were used to evaluate knee pain and functional recovery before operation, 2 weeks, 3 months and 12 months after operation. And the congruence angle (CA), patellar tilt angle (PTA), and femala-tibial angle (FTA) were measured respectively before and 12 months after operation to evaluate the congruence of patellar joint, and the improvement of line of gravity of lower limb.@*RESULTS@#All 43 patients were followed up for more than 12 months, with a follow-up time of 14 to 28 (19.60±4.50) months. The VAS scores decreased from 6.65±0.65 before operation to 2.16±0.95, 0.51±0.77 and 0.33±0.64 at 2 weeks, 3 months and 12 months after operation, and the difference was statistically significant (@*CONCLUSION@#High tibial osteotomy combined with arthroscopic lateral retinacular release can relieve weight-bearing pain in frontal axis and improve the function of knee in sagittal axis.

OBJECTIVE@#To evaluate the cartilage regeneration in the knee joint by arthroscopy after high tibial osteotomy.@*METHODS@#Eleven patients were included in the study who were treated with high tibial osteotomy and underwent microscopy when the internal fixation was unloaded from September 2017 to September 2019. Among them, there were 2 males and 9 females, aged from 55 to 64 years old. The internal and external compartment pictures of the knee were taken before and after surgery of removing the internal fixation and the International Cartilage Repair Society (ICRS) grading systerm was used to evaluate the degree of cartilage damage on the medial and lateral femoralcondyles and tibial plateau. The Westrn Ontarioand Mcmaster Universities osteoarthritis index (WOMAC) and the weight bearing line (WBL) were used to evaluate the function of the knee and the alignment of the lower limb.@*RESULTS@#All 8 patients were followed up for more than 12 months, ranging from 12 to 22 months. The degenerated cartilage of the medial femoral condyle and medial tibial plateau was covered by newly regenerated cartilage. WOMAC score decreased from 102-127 to 41-52 and WBL was improved from 17%-34% to 58%-64%. All incisions healed in stageⅠ, and no complications such as internal fixation rupture and infection occurred during and after the operation.@*CONCLUSION@#High tibial osteotomy can relieve the pain of the knee and the dysfunction by adjusting lower limb alignment, and the degenerated cartilage could be regenerated in the medial femoral condyle and medial tibial plateau.

<p><b>OBJECTIVE</b>To report the operative technique and clinical results of the neurocutaneous vascular axial flap with perforating vessels as its pedicle.</p><p><b>METHODS</b>An axial skin flap was designed along the axis of small paraneural vessels that was close to a concomitant cutaneous nerve. The cutaneous perforating branches of major arteries were used as the pedicle, which provided a rotation arc for the flap to cover the defects in the distal site of extremities. 43 neurocutaneous vascular axial flaps were transferred, including 13 sural neurocutaneous axial flaps (30 cm x 12 cm to 16 cm x 8 cm) supplied by perforating branches of the peroneal vessel; 9 saphenous neurocutaneous axial flaps (15 cm x 8 cm to 5 cm x 4 cm) with posterior tibial perforators as the pedicle; 8 posterior antebrachial neurocutaneous axial flaps (16 cm x 6 cm to 10 cm x 4 cm) based on the dorsal branch of the anterior interossea vessel and 13 reversed neurocutaneous axial flaps (6.0 cm x 3.5 cm to 2.5 cm x 1.5 cm) on the dorsal hand pedicled with the perforators at the interdigital web space.</p><p><b>RESULTS</b>42 flaps survived completely. One flap underwent venous congestion with necrosis on the distal one fourth of the flap. The color and texture of the flaps were good. The appearance and functional results were satisfactory as revealed by follow-up for 6 to 24 months.</p><p><b>CONCLUSIONS</b>The modified operation combines the advantages of both the perforator flap and the neurocutaneous axial flap, enlarges the size of the flap and extends the scope of reconstruction. The flap is characterized with delicate designation, easy dissection and reliable blood supply. It is a good method in repairing the skin defects of the extremities.</p>
