Objective To investigate the effect of the treatment of humeral lateral condyle fracture in children through elbow arthroscopy. Method From July 2003 to May 2008, 128 children with humeral lateral condyle fracture were randomly divided into open reduction group and arthroscopy group, each group of 64 cases. Results All 128 children received 12-24 months of follow up, with average of (18.07 ± 5.63) months. In arthroscopy group, the blood loss averaged(34.6 ± 9.1) ml, incision length of(0.98 ± 0.20) cm, and after the first 3 days the VAS was(3.99 ± 1.33) scores. However, in open reduction group, the blood loss averaged (109.9 ± 18.9) ml, incision length of (5.38 ± 1.30) cm, and the VAS was (7.03 ± 2.80) scores. All those in arthroscopy group were much better than those in open reduction group,the differences were statistically significant (P<0.01 or < 0.05). According to Mayo score, the total fine rate was 85.9%(55/64) in open reduction group, and 98.4%(63/64) in arthroscopy group (P<0.05). About in the incidence of postoperative complications,there were 8 cases of delayed healing, S cases of inside inversion or outside eversion elbow varus deformity, 9 cases of pin tract infection in open reduction group. However there were 1 cage of delayed healing, 2 cases of inside inversion and outside eversion elbow varus deformity, 1 case of pin tract infection in arthroscopy group(P< 0.01). Conclusion Arthroscopy operation has the advantages of the small incision, reset reduction accurate, less complications ,and is an effective method of treating the lateral condyle fractures in children.

Objective:To investigate the clinical efficacy of arthroscopy combined with sodium hyaluronate and platelet-rich plasma in the treatment of Stoller grade III meniscus injury.Methods:Sixty patients with Stoller grade III meniscus injury who received treatment in The Second People's Hospital of Liaocheng from October 2019 to October 2020 were included in this study. They were randomly divided into an observation group and a control group ( n = 30 per group). Patients in the observation group were treated with arthroscopy combined with sodium hyaluronate and platelet-rich plasma, while patients in the control group were treated with arthroscopy combined with sodium hyaluronate. Before and 1, 3, and 6 months after surgery, the Visual Analogue Scale (VAS) score, Lysholm score, and The Western Ontario and McMaster Universities Arthritis Index (WOMAC) score of the knee joint were compared between the two groups. Results:There were no serious complications in each group. Compared with pre-treatment, the VAS and Lysholm scores of the knee joint in both groups significantly decreased at 1, 3, and 6 months after surgery, while the WOMAC score showed a significant increase ( F = 514.96, 673.19, 96.31, 124.16, 230.99, 531.84, all P < 0.001). After 3 and 6 months of treatment, the VAS score in the observation group was (1.1 ± 0.5) points and (0.8 ± 0.4) points, respectively, which were significantly lower than (2.5 ± 0.7) points and (1.3 ± 0.5) points in the control group ( t = 8.91, 4.28, both P < 0.001). After 3 and 6 months of treatment, the Lysholm score of the knee joint in the observation group was (86.2 ± 9.1) points and (93.8 ± 13.2) points, respectively, which were significantly higher than (79.8 ± 11.3) points and (87.5 ± 9.2) points in the control group ( t = 2.42, 2.14, both P < 0.05). After 3 and 6 months of treatment, the WOMAC score in the observation group was (17.5 ± 3.6) points and (16.5 ± 3.2) points, respectively, which were significantly lower than (25.4 ± 5.2) points and (24.8 ± 6.4) points in the control group ( t = 6.84, 6.35, both P < 0.001). Conclusion:Arthroscopy combined with sodium hyaluronate and platelet-rich plasma is more effective in treating Stoller III grade meniscus injury than arthroscopy combined with sodium hyaluronate. The former therapy can be promoted in the clinic.
