In this special issue, several papers related to clinical application of arthroscopic surgery are published, which present the current situation of arthroscopic techniques in our country. As a technique of minimally invasive orthopedics, arthroscopy is used in examination, diagnosis and treatment of joint diseases, which is the trend of modern surgery. Arthroscopy has been widely used in surgical procedures in knee diseases, and now it expands the scope of application to other joints, such as shoulder, elbow, wrist, hip, ankle and even smaller joints. The application scope of arthroscopy has spread from arthroscopic debridement to reparative and reconstructive surgery. Some innovation has been made in extra-articular surgeries. Researchers conduct in depth study and exploration in the basic and clinical application of arthroscopy. Arthroscopic surgery has become an indispensable branch of modern orthopedics.

Arthroscopic treatment of ankle impingement syndrome (AIS) is a minimally invasive surgical procedure used to address symptoms caused by impingement in the ankle joint. This syndrome occurs when there is abnormal contact between certain bones or soft tissues in the ankle, leading to pain, swelling, or limited range of motion. Traditionally, open surgery was the standard approach for treating AIS. However, with advancements in technology and surgical techniques, arthroscopic treatment has become a preferred method for many patients and surgeons. With improved visualization and precise treatment of the arthroscopy, patients can experience reduced pain and improved functionality, allowing them to return to their daily activities sooner. In this paper, we reviewed the application and clinical efficacy the of arthroscopic approach for treating AIS, hoping to provide a reference for its future promotion.

OBJECTIVETo investigate the clinical results of arthroscopic surgery for the treatment of stiff elbow.

METHODSFrom October 2010 to December 2012, 27 patients with stiff elbow were treated with arthroscopic debridement and joint capsular releasing. There were 18 males and 9 females, ranging in age from 24 to 54 years old, with an average of 35.7 years old. Analgesia and rehabilitation were necessary after operation. Mayo criteria system was used to evaluate therapeutic effects.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 18 months, with a mean of 13.5 months. The mean maximum flexion angle of patients improved from preoperative (61.5 ± 30.1) degrees to postoperative (102.5 ± 20.1) degrees; and the mean maximum extension angle improved from preoperative (34.8 ± 12.1) degrees to postoperative (16.3 ± 16.1) degrees; the average total range of motion improved from preoperative (34.2 ± 21.0) degrees to postoperative (84.9 ± 9.2) degrees. According to the Mayo criteria system, the average score increased from preoperative 60.5 ± 13.4 to postoperative 88.7 ± 6.3; ten patients got an excellent result, 13 good and 4 fair.

CONCLUSIONArthroscopic surgery to treat elbow stiffness has such advantages as minimal invasion, less blood loss, fast recovery, and clear visualization, which is effective to improve elbow joint functions with less complications.

OBJECTIVETo study the methods and effects of rehabilitation exercises after single total knee replacement (TKR).

METHODSFrom May 2007 to May 2009, 38 patients with knee joint diseases were treated with artificial total knee replacement, and the postoperative rehabilitation training was conducted. Among the patients, 20 were males and 18 were females, ranging in age from 50 to 82 years, with an average of 65 years. Course of diseases ranged from 4 to 35 years. Thirty patients were traumatic arthritis, 5 patients were osteoarthritis, and 3 patients were rheumatoid arthritis. Clinical symptoms were knee joint pain and dysfunction; some patients had morning stiffness and bone hypertrophy, a few of them accompanied with knee varus or valgus, quadriceps atrophy. X-ray films showed narrow joint space, osteophyte, cystic changes, and subchondral bone sclerosis.

RESULTSAll the patients were followed up ranging from 6 to 12 months. According to HSS knee score system, the mean scores were 40.22 +/- 7.39 points before operation, and 87.47 +/- 6.60 points after rehabilitation. The difference was statistically significant (t = 31.56, P < 0.01).

CONCLUSIONRehabilitation training after single total knee replacement is the key to ensure the effects of the operation. The rehabilitation training in our hospital has satisfactory results, and is worth to popularize.

OBJECTIVETo evaluate the biomechanical performance of the spinal universal fixation system(GSPS) in treating the diseases related to spinal instability.

METHODSFour instable models and 4 fracture models were made of fresh pig's thoracolumbar specimens (T10-L3). Self-designed GSPS were used in the simulated operation. Axial loading test and torsion test were made. The stress-strain relation of the GSPS was observed. The extracting force of link bar from elastic jig was tested.

RESULTSThe strain value of each tested point changed linearly when the axial load changed from 0 to 600 N. There was linear relation between the torsion and the torsion angle. The latter was less than 6 degrees when the former reached 300 N x cm. The minimum extracting force of the link bar from the elastic jig was more than 3 300 N.

CONCLUSIONThe GSPS has high energy and high elasticity on anti-axial and anti-torsion load. It is stable to use elastic link bar.
