ObjectiveTo investigate evaluation and treatment of osteochondral injury of knee joint and its effectiveness.MethodsBetween January 2010 and January 2016, 17 patients with osteochondral injury of knee joint were admitted. There were 2 males and 15 females, with an average age of 19.3 years (range, 15-33 years). The causes of injury included the sprain in 14 cases and knee hyper-extension and varus due to violence in 3 cases. The osteochondral injury located at patella in 8 cases, lateral femoral condyle in 4 cases, medial femoral condyle in 1 case, and tibial plateau in 4 cases. There were 15 cases of fresh fractures and 2 cases of old fractures. The Lysholm score of the knee joint was 31.6±2.3. After open reduction of osteochondral fractures of 14 cases, the absorbable rods (9 cases), absorbable cartilage nail (3 cases), or absorbable sutures (2 cases) were selected for fixation. The osteochondral fractures at the medial tibial plateau margin (non-weight-bearing area) in 3 cases were removed.ResultsThe incision fat liquefaction occurred in 1 case after operation and healed after debridement. The other incisions had primary healing. All 17 patients were followed up 6 months to 2 years (mean, 13 months). Thirteen of 14 patients with internal fixation had good fractures healing without traumatic arthritis; 1 case of patella osteochondral fracture did not heal. Three patients with non-weight-bearing osteochondral removal had no narrowing of the medial joint space and traumatic arthritis during the follow-up. The Lysholm score of knee joint at 1 year after operation was 91.3±1.1, which significantly improved when compared with preoperative score (t=7.136, P=0.001).ConclusionFor the osteochondral injury of the knee joint, the osteochondral block with full-layer cancellous bone can be treated with open reduction and internal fixation; while osteochondral block with punctate cancellous bone can be directly remove.
Objective To evaluate the clinical efficacy and safety of biportal endoscopic discectomy combined with annulus fibrosus suture in the treatment of recurrent lumbar disc herniation (RLDH). Methods The clinical data of patients with RLDH who underwent biportal endoscopic discectomy combined with annulus fibrosus suture using a single-use suture device at Mianyang Orthopaedic Hospital between May 2020 and July 2022 were retrospectively collected. Visual Analogue Scale (VAS) scores for low back and leg pain and Oswestry Disability Index (ODI) scores on postoperative Day 3 and at the last follow-up were used to assess pain and functional status. Postoperative lumbar CT, MRI, and dynamic X-rays were obtained to evaluate the extent of decompression, disc removal, and spinal stability. Clinical efficacy during follow-up was assessed using the MacNab criteria since postoperative 3 months. Results Twenty-one RLDH patients (16 males, 5 females) with a mean age of (45.14±15.26) years (range: 17-62 years) were included. The involved segments were L3-L4 in 1 case, L4-L5 in 9 cases, and L5-S1 in 11 cases. All surgeries were successfully completed without complications such as nerve injury, symptomatic epidural hypertension, dural tear, cerebrospinal fluid leakage, or infection. All patients were followed up for a mean duration of (11.38±3.51) months (range: 4-17 months). No recurrence of disc herniation or segmental instability was observed during follow-up. Significant improvements were seen in VAS scores for low back pain (2.90±0.70, 1.38±0.81), leg pain (2.33±0.58, 1.29±0.46), and ODI scores [(24.12±5.05)%, (11.29±1.86)%] on postoperative Day 3 and at the last follow-up compared to the preoperative values [5.90±1.09, 6.10±0.77, (57.08±9.72)%; all P<0.05]. According to the MacNab criteria, the clinical efficacy was rated as excellent in 16 cases, good in 3 cases, and fair in 2 cases, yielding an excellent-good rate of 90.5%. Conclusion Biportal endoscopic discectomy with annulus fibrosus suture is a safe and effective treatment for RLDH, demonstrating favourable clinical outcomes and warranting further research and application.
Objective To investigate the clinical efficacy of endoscopy-assisted anterior cervical discectomy and fusion for cervical spondylosis. Methods The clinical data of patients treated with water medium endoscopy-assisted anterior cervical discectomy and fusion for cervical spondylosis at Mianyang Orthopedic Hospital between September 2021 and September 2023 were retrospectively collected. The surgical efficacy and nerve injury recovery were evaluated based on the Neck Disabilitv Index (NDI), Japanese Orthopaedic Association (JOA) score, improvement rate of JOA score, Cobb angle and height changes of the affected intervertebral space before surgery and at the last follow-up, as well as the occurrence of surgical complications. Results A total of 29 patients were included, including 18 males and 11 females. The average age was (52.34±8.96) years, and the average duration of illness was (17.31±6.60) months. The average follow-up time was (11.69±3.41) months. At the last follow-up, the patients’ NDI (3.55±3.09 vs. 17.28±5.51), Cobb angle [(15.25±4.83) vs. (−1.34±7.50)°], intervertebral height [(8.04±0.82) vs. (4.67±0.95) mm], and JOA score (15.90±1.11 vs. 11.17±1.65) improved compared to preoperative levels (P<0.05). The JOA score improvement rate assessment showed that 16 cases were excellent, 11 cases were fine, 2 cases were moderate, and the excellent and fine rate was 93.10%. All patients did not experience serious complications after surgery. Conclusion Water medium endoscopy-assisted anterior cervical discectomy and fusion for cervical spondylosis has good clinical efficacy and safety.
