Objective To evaluate the surgical technique and effectiveness of arthroscopic treatment for lateral discoid meniscus injury. Methods Between January 2010 and May 2011, 38 patients (42 knees) with lateral discoid meniscus injuries underwent arthroscopic treatment. There were 23 males (24 knees) and 15 females (18 knees), aged 7-62 years (median, 32.8 years). The disease duration was 7 days to 40 years (median, 8.6 months). According to Watanabe’s classification of discoid meniscus, 22 knees were classified as complete type, 19 knees as incomplete type, and 1 knee as Wrisberg type. Meniscus plasty combined with suture was performed in 25 patients (28 knees), partial meniscectomy in 12 patients (13 knees), and complete meniscectomy in 1 patient (1 knee). After operation, the rehabilitation training programs (including straight-leg-raising exercise and range of motion exercise) were carried out. Results All incisions healed primarily. The patients basically had normal activities after 3-4 weeks. All the patient were followed up 12-18 months (mean, 14.3 months). No joint locked or clicking symptom occurred; no tear or revision was noted during follow-up. At 3 months, 6 months, and 1 year after operation, the range of flexion and extension were significantly improved when compared with ones at preoperation (P lt; 0.05). Based on Ikeuchi’s grading, the results were excellent in 22 knees, good in 16 knees, and fair in 4 knees with an excellent and good rate of 90.4%. The Lysholm score was significantly increased to 88.57 ± 2.95 at immediate, 91.02 ± 4.17 at 3 months, 92.90 ± 3.36 at 6 months, and 94.74 ± 3.52 at 12 months after operation from 69.38 ± 4.59 before operation (P lt; 0.05). C onclusion Treatment of lateral discoid meniscus injury under arthroscopy has the advantages of minor trauma, precise resection or repair meniscus, preservation of more meniscus function, and low incidence of osteoarthritis. If the operation is combined with standard rehabilitation training, the short-term effectiveness can be enhanced.
Objective To investigate the effectiveness of meshy fascia encapsulating cancellous bone graft in repair of bone defect after limb fractures. Methods A clinical data of 21 cases of traumatic bone defect after limb fractures, who were treated with meshy fascia encapsulating cancellous bone graft between June 2011 and December 2016, was retrospectively analyzed. There were 13 males and 8 females, aged 14-64 years with an average of 40.1 years. The location of bone defect included humerus in 3 cases, radius in 5 cases, ulna in 4 cases, femur in 2 cases, and tibia in 7 cases. AO classification of primary fractures were type A in 2 cases, type B in 7 cases, and type C in 12 cases. There were 14 cases of open fracture, and 7 cases of closed fracture associated with bone defect. The time from injury to bone defect repair was 5-165 days (mean, 21.3 days). The length of bone defect was 2.5-6.5 cm with an average of 4.5 cm. Results The operation time was 86-130 minutes (mean, 101 minutes). The intraoperative blood loss was 185-647 mL (mean, 316 mL). One case of superficial infection and 2 cases of delayed healing of incision occurred after operation, and no neurovascular injury occurred. All the 21 patients were followed up 12-36 months (mean, 19 months). The clinical healing time was 2.5-7.0 months (mean, 5.4 months); no delayed healing and nonunion occurred, the bony healing rate was 100%. There was no deep infection, infection recurrence, broken of internal fixator, or refracture. At last follow-up, the grading of bony healing were all rated as excellent, and the functional recovery of the affected limb was excellent in 12 cases, good in 7 cases, and fair in 2 cases with an excellent and good rate of 90.5%. Conclusion Meshy fascia encapsulating cancellous bone graft in repair of bone defect after limb fracture is characterized by easy to harvest fascia, simplicity of operation, no adverse reaction, lower cost, and satisfactory results.
