5 months). At last follow-up, the pain score of the ankle joint Kofoe score was 40-50, with an average of 44; the functional score was 17-27, with an average of 25; the mobility score was 8-18, with an average of 14; and the effectiveness was rated as excellent in 8 cases, good in 7 cases, and poor in 1 case.

For Gustilo ⅢA Pilon fractures, the NRD technique combined with Ilizarov circular external fixation has advantages of good fracture fixation and drainage effects, which greatly reduces the complications of traditional treatment options and the number of operations.

To discuss the feasibility and accuracy of distal femoral patient-specific cutting guide in total knee arthroplasty (TKA) based on knee CT and full-length X-ray film of lower extremities.

Between July 2016 and February 2017, 20 patients with severe knee joint osteoarthritis planned to undergo primary TKA were selected as the research object. There were 9 males and 11 females; aged 53-84 years, with an average of 69.4 years. 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.

To explore the method and effectiveness of multidirectionally three-dimensional steel wire ring sleeve fixation in the treatment of inferior patellar pole avulsion fractures.

Betweern January 2015 and January 2019, 22 patients with inferior patellar pole avulsion fractures were admitted and treated. There were 12 males and 10 females. 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°). 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). 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). see more 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.
