The shoulder joint is the most prone to dislocation in the whole body, and more than 95% of them are anterior dislocation. Improper treatment after the initial dislocation is easy to lead to recurrent anterior dislocation or anterior shoulder instability, and the outcomes following conservative treatment is poor. Anterior shoulder instability can damage the soft tissue structure and bone structure that maintain the stability of shoulder joint, among which bone structure is the most important factor affecting the stability of shoulder joint. Diagnosis should be combined with medical history, physical examination, and auxiliary examination. Currently, three-dimensional CT is the most commonly used auxiliary examination means. However, various bone defect measurement and preoperative evaluation methods based on three-dimensional CT and the glenoid track theory have their own advantages and disadvantages, and there is still a lack of gold standard. Currently, the mainstream treatment methods mainly include Bankart procedure, coracoid process transposition, glenoid reconstruction with free bone graft, Bankart combined with Remplissage procedure, and subscapular tendon binding tamponade, etc. Each of these procedures has its own advantages and disadvantages. For the diagnosis and treatment of anterior shoulder instability, there are still too many unknown, further research and exploration need to be studied.
ObjectiveTo summarize the application status and progress of the strategies to augment tendon-to-bone healing. MethodsThe present researches focused on augmentation of tendon-to-bone healing were extensively reviewed. ResultsThe present strategies to augment healing of tendon-to-bone by enhancing the location environment, and increasing the cell numbers and relative growth factor. The mainly strategies include using calcium phosphate materials, biocompatible scaffolds and glue, growth factors, cell matrix, platelet-rich plasma, and periosteum. Although periosteum have been used in clinical and got some possitive effects, the others still not be used in clinical and needs further studies. ConclusionThere are many strategies to enhance the ability of tendon-to-bone healing, which got some positive results, but results of studies were varied. Thus, further fundamental research and clinical studies are required to achieve the best effects.
Objective To review the research progress of diagnosis and treatment system for knee dislocation (KD) based on the stage and classification of posteromedial structure and posterolateral corner injury, so as to provide guidance for clinical work. Methods The relevant literature on the classification, diagnosis and treatment was extensively reviewed. Results At present, the criterion of the stage and classification of KD mainly include classification based on the size of the injury energy, Kennedy classification, and the improved Schenck classification, but they are not perfect because of no stage and classification of multiple ligament injury and no standardized treatment of different injuries. Hua Xi Knee Dislocation and Multiple Ligament Injury (HX-KDMLI) has optimum plan for injury treatment of posteromedial structure and posterolateral corner injury in KD based on stage and classification. Conclusion At present, there is no unified opinion on stages and classifications of the posteromedial structure and posterolateral corner injury in KD as well as on diagnosis and treatment. HX-KDMLI has certain feasibility for the stage and classification of the posteromedial structure and posterolateral corner injury in KD, to a certain extent, it can be used as reference for the diagnosis and treatment of KD.
ObjectiveTo summarize the diagnosis and measurement methods of bone defect in anterior shoulder instability (glenoid bone defect and Hill-Sachs lesion).MethodsThe related literature on the diagnosis and measurement of the bone defect in anterior shoulder instability was reviewed and summarized.ResultsThe commonly used techniques for the diagnosis of anterior glenoid bone defect and Hill-Sachs lesion of humeral head include X-ray, CT, MRI, arthroscopy, arthrography. The methods for measuring the degree of anterior glenoid bone defect include Griffith method, glenoid index method, Pico method, and best-fit circle method. The indexes for measuring the Hill-Sachs lesion include the length, width, depth, and volume. X-ray is mainly used for primary screening. Best-fit circle method on three-dimensional (3D) CT reconstruction is commonly used to measure the glenoid bone defect currently. Glenoid track theory on 3D CT reconstruction is popular in recent years. Reliability of measuring the glenoid bone defect and Hill-Sachs lesion with MRI and arthroscopy is still debatable. Arthrography is more and more used in the diagnosis of shoulder joint instability of bone defect and concomitant soft tissue injury.ConclusionHow to improve the accuracy of evaluating glenoid bone defect and Hill-Sachs lesion before surgery still need further study.
Objective To investigate the method and the effectiveness of arthroscopy and/or arthrotomy combinedwith postoperative radiotherapy for diffuse pigmented villonodular synovitis (PVNS) of the knee. Methods BetweenSeptember 2000 and August 2010, 97 patients with diffuse PVNS of the knee were treated. There were 38 males and 59 femaleswith a median age of 33 years (range, 8-75 years). The disease duration ranged from 1 week to 30 years, including 52 left kneesand 45 right knees. There were 10 recurrent cases. The extention and flexion of the knee joint were (1.9 ± 2.3)° and (122.9 ± 5.6)°,respectively; the Lysholm score was 43.2 ± 6.7; and the International Knee Documentation Committee (IKDC) score was53.2 ± 5.7, preoperatively. According to the scope and degree of the knee joint lesions, simultaneous anterior and posteriorsynovectomy was performed under arthroscopy in 82 cases, synovectomy under arthroscopy and removal of posterior extraarticularlesion by arthrotomy in 3 cases, synovectomy and the soft tissue lesions resection under arthroscopy in 9 cases, andstaging resection and bone graft in 3 cases. After operation, 76 patients received postoperative radiotherapy. Results Poplitealartery was injuryed in 1 case and the branch of popl iteal veins were injuryed in 3 cases during operation. Intra-articularhemorrhage occurred in 1 case at 3 days after operation. The other patients achieved heal ing of incision by first intentionwithout nerve damage and other complications. All patients were followed up 1 year and 3 months to 11 years and 2 months(median, 61 months) postoperatively. During follow-up, 89 cases had no relapse. At 15 months after operation, the extentionand flexion of the knee joint were (0.2 ± 1.3)° and (135.9 ± 6.6)°, respectively; the Lysholm score was 89.8 ± 5.8; and the IKDCscore was 87.8 ± 5.8. All indexes were significantly improved when compared with the preoperative ones (P lt; 0.05). At 6 monthsto 8 years postoperatively, 8 cases had occurrence, and they had sl ight limitation of the range of motion but had no pain andswelling of the knees after reoperation. Conclusion According to the scope and degree of the knee joint lesions, arthroscopyand/or arthrotomy combined with postoperative radiotherapy should be chosen for diffuse PVNS of the knee so as to obtain good effectiveness. Radiotherapy and enough total radiation dose are important factors to insure no recurrence.
Objective To investigate the method and the effectiveness of a combination of the arthroscopic debridement and joint irrigation postoperatively for treating gouty arthritis of the knee. Methods Between August 2000 and November 2009, 41 patients with gouty arthritis of the knee were treated by arthroscopic debridement. All patients were males with an average age of 42 years (range, 21-71 years), including 8 incipient cases and 33 relapsed cases. The unilaterial knees wereinvolved in 36 cases, including 22 left knees and 14 right knees, and both in 5 cases. The disease duration ranged from 2 months to 20 years (median, 6 years and 2 months). The extention, flexion, and range of motion (ROM) of the knee joint were (4.88 ± 6.22), (93.95 ± 35.33), and (87.79 ± 35.19)°, respectively, and Lysholm score was 63.2 ± 11.7 preoperatively. The serum uric acid levels were higher than normal value in 32 cases. Twenty-seven cases were definitely diagnosed as gouty arthritis before operation. Arthroscopic debridement was performed in 11 cases, and the arthroscopic debridement with joint irrigation postoperatively in 30 cases. After operation, the anti-gout agents and diet control were given. Results Arthroscope and pathologic examinations confirmed diagnosis of gouty arthritis in 41 patients. Intra-articular hemorrhage occurred in 1 case and was cured after arthroscopic evacuation of hematoma. The other patients achieved heal ing of incision by first intention. All 41 patients were followed up 15-126 months (mean, 50 months) postoperatively. The Lysholm score was 96.8 ± 5.8 at 15 months after operation, showing significant difference when compared with the preoperative value (t= — 13.844, P=0.000). The postoperative extention (1.16 ± 3.91)°, flexion (125.93 ± 18.65)°, and ROM (126.86 ± 16.33)° of the knee joint were significantly improved when compared with the preoperative ones (P lt; 0.05). Thirteen cases (14 knees) recurred postoperatively; but occurrence frequency and the duration were decreased and the symptoms of joint swell ing and pain were improved. Conclusion The arthroscopicdebridement is effective in cleaning up uric acid crystals thoroughly, reducing wounds, and speeding up recovery. If antigout agents and diet control can be used postoperatively, the recurrence of gouty arthritis can be prevented effectively, and the progression can be delayed.

Methods A total of 23 patients (28 knees) with synovial chondromatosis were diagnosed and treated in our hospital from January 2005 to October 2009. All of the patients underwent radiographic imaging examination, knee joint range of motion (ROM), visual analogue scale (VAS) and Lysholm score. According to distinct arthroscopic appearance, superficial pattern was found in 6 patients and loose body lesion pattern was in 17. Additionally, combined with pathological examination, according to the Milgram staging，Stage Ⅱ was in 6 patients and Stage Ⅲ was in 7. Arthroscopic limited synovectomy and removal of loose bodies were performed on all the patients. Results The patients were followed up for 13-57 months with the mean of (32.3±6.7) months. The wound of all patients healed up. The time of returning to normal work and life was (5.05±2.43) days for average. The postoperative symptom was markedly alleviated in 21 patietns and partly alleviated in 2. All patients were satisfied with the therapeutic effect. The mean activity of knee joint was significantly different befoe and after the surgery (Plt;0.05) preoperative extension and flexion degrees were (14.29±16.34) and (106.07±35.83) degrees, respectively; postoperative extension and flexion degrees were (1.79±2.79) and (132.64±35.64) degrees (flexion) , respectively. The mean VAS score of weight bearing walking was 0.37±0.65 after theoperation and 3.81±2.02 before the peration; the difference was significantly different (Plt;0.05). The preoperative Lysholm knee score was 34-67 with the mean of 43.20±8.24, and the post-operative score was 71-99 with the mean of 86.72±5.40. There were differences in preoperative and post-operative scores (Plt;0.05) . Radiographic imaging examination of knee joint was performed 1 year after the opertation, no loose bodies was seen and no patients recurred. Conclusion The therapeutic effect of arthroscopic limited synovectomy and removal of loose bodies is good on synovial chondromatosis.
