There were 9 males and 11 females; aged 53-84 years, with an average of 69.4 years. link= DOTAP chloride cost The body mass index was 22.1-31.0 kg/m
, with an average of 24.8 kg/m
. The preoperative range of motion (ROM) of the knee joint was (103.0±19.4)°, the pain visual analogue scale (VAS) score was 5.4±1.3, and the American Hospital of Special Surgery (HSS) score was 58.1±11.3. Before operation, a three-dimensional model of the knee joint was constructed based on the full-length X-ray film of lower extremities and CT of the knee joint. The distal femoral patient-specific cutting guide was designed and fabricated, and the thickness of the distal femoral osteotomy was determined by digimpared with the preoperative measurements, there was a significant difference in mFTA (
<0.05), and there was no significant difference in aLDFA, FMAA, or DFFA; compared with the preoperative plan, there was no significant difference in FPFA, aLFC, or α angle (
>0.05).
The use of distal femoral patient-specific cutting guide based on knee CT and full-length X-ray film of lower extremity can achieve precise osteotomy, improve coronal and sagittal limb alignment, reduce intraoperative blood loss, and obtain satisfactory short-term effectiveness.

DOTAP chloride cost The age ranged from 20 to 69 years, with an average age of 39.4 years. The causes of injury included 9 cases of traffic accident and 13 cases of falling. All of them were unilateral closed injury of knee joint, including 7 cases of skin contusion around patella. Preoperative range of motion of the affected knee was (20.82±7.16)° (range, 10°-35°). link2 The time from injury to operation ranged from 3 to 12 days, with an average of 5.9 days. During the operation, the inferior patellar avulsion fracture was reduced with forceps; the patella was circumferentially ligated through the distal bone surface of the fracture with 0.8 mm diameter steel wire; then 3 longitudinal bone tunnels w wire, failure of internal fixation, and other complications occurred during follow-up.
Multidirectionally three-dimensional steel wire ring sleeve fixation in the treatment of inferior patellar pole avulsion fractures has the advantages of reliable fixation, early functional recovery, and fewer complications, so the effectiveness is satisfactory.

To investigate the effect of different saline irrigation volume under arthroscopy on early postoperative pain and swelling of the knee.
The clinical data of 539 patients with meniscus injury treated by arthroscopic menisci reformation who met the selection criteria between July 2016 and February 2020 were retrospectively analyzed. They were divided into three groups according to the continuous saline irrigation volume during the operation 176 patients in the non-irrigation group (group A), 183 patients in the 1 liter-irrigation group (group B), and 180 patients in the 3 liters-irrigation group (group C). link2 There was no significant difference in gender, age, cause of injury, sides of injury, body mass index, disease duration, smoking history, and classification of meniscus injury among 3 groups (
>0.05). At 6, 12, 24, 48, and 72 hours after operation, the patient's pain level was evaluated by the visual analogue scale (VAS) score, and the knee swelling situation was evaluated by the swelling ratings (thed at the 3rd day after operation than the 1st day, and there was no significant difference in the skin temperature of the knee among the 3 groups at each time point after operation (
>0.05). There was no significant difference in CRP level within the group and among the 3 groups at each time point after operation (
>0.05). Range of motion of the knee in each group increased gradually at the 1st, 3rd, and 5th days after operation, and there was no significant difference among the 3 groups at each time point after operation (
>0.05).
The different continuous saline irrigation volume would not affect the early postoperative pain, swelling, and inflammation of the knee during the arthroscopic menisci plasty.

To investigate the effectiveness of arthroscopic reinforced reconstruction of anterior cruciate ligament (ACL) with autologous hamstring tendon combined with anchor suture band.
Between February 2016 and March 2018, 60 patients who were to be treated with arthroscopic ACL reconstruction and met the selection criteria were selected in the study. Among them, 30 cases were reconstructed with autologous hamstring tendon combined with anchor suture band (trial group), and 30 cases were reconstructed with simple autologous hamstring tendon (control group). There was no significant difference in gender, age, disease duration, cause of injury, injury side, and preoperative Lysholm score, Tegner score, and International Knee Documentation Committee (IKDC) score between the two groups (
>0.05). After reconstruction, the patients in the trial group were allowed to start knee flexion and extension activities early without wearing an adjustable brace, while the patients in the control group were required to wear no significant difference in Lachman test results between the two groups at each time point after operation (
>0.05). There was a significant difference in pivot shift test results at 6 months after operation between the two groups (
<0.05); but there was no significant difference at other time points (
>0.05).
The effectiveness of ACL reinforcedreconstruction with autologous hamstring tendon combined with anchor suture band is satisfactory. Compared with using autologous hamstring tendon alone, it has better initial strength and joint stability, and is more conducive to early postoperative functional exercise and functional recovery of knee joint.

There were 43 cases of acute injury and 3 cases of old injury. The anterior drawer test and the posterior tibia sign were positive in 4 cases, the posterior drawer tests and the posterior tibia sign were positive in 46 cases, the varus stress tests were positive in 10 cases, and the valgus stress tests were positive in 6 cases. The difference of dial-test at 30° knee flexion between affected and healthy sides was (5.20±3.91)°. The tibia posterior displacement under posterior stress position was (12.03±2.38) mm. The Lysholm score of the knee joint was 36.68±7.89, the International Knee Documentation Committee (IKDC) score was 33.58±5.97, and the American Orthopaedic Foot and Ankle Association (AOosterior drawer test and the posterior tibia sign were positive in 1 case and negative in 39 cases; the anterior drawer test and the varus and valgus stress tests were all negative.

To investigate the effectiveness of modified patellar tendon reconstruction using hamstring autograft in the treatment of chronic patellar tendon rupture and defects.
The clinical data of 11 patients with chronic patellar tendon rupture and defects admitted between January 2015 and August 2018 were retrospectively analyzed. The patient were treated with inverted U-shaped reconstruction technique using hamstring autografts, in which 2 bone tunnels were created at the level of 1/2 and lower 3/4 of the patella, and 1 bone tunnel was created beneath the tibial tuberosity. DOTAP chloride cost There were 8 males and 3 females with an average age of 30.1 years (range, 10-61 years). The average interval from the primary injury to the operation was 9.5 months (range, 2-36 months). According to Yousef classification, there were 7 cases of type A2, 3 cases of type B2, and 1 case of type C2. The length of the patella tendon defect was measured when the patella was reducted intraoperatively with an average of 4.5 cm (range, 2.7-7.1 cm). 1.32, respectively.
