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.

Anterior disc displacement is a common subtype seen in temporomandibular disorders (TMD) patients. It may cause mandibular movement disorders, such as clicking of joint, intermittent closed lock, limitation of mouth opening, etc. These disorders may affect the life qualities of patients. Anterior disc displacement may also cause mandibular malformations, especially among adolescents, which may affect the growth of condyle, therefore may have a correlation with mandibular retrusion or mandibular deviation when grown up. This paper going to review the influences of anterior disc displacement on oral mandibular function and morphology and their biological mechanisms.

Snapping hip syndrome is a relatively common problem that can be easily managed with conservative treatment. This syndrome can be divided into external, internal and intra-articular types. Internal snapping hip syndrome is the rarest amongst these and its etiology is not well understood. We report a unique case of osteochondroma arising from the anterior inferior iliac spine (AIIS), which caused the internal snapping hip syndrome with hip pain and restriction of activity. This rare case of snapping hip syndrome from the AIIS was treated surgically and the symptoms completely disappeared after excision of the tumor.

In this study, we reported a case of progressive pseudorheumatoid dysplasia in Peking University Third Hospital. A 56-year-old male patient presented with hip joint pain for more than 40 years and multiple joints pain with limitation of movements of these joints for 28 years. This patient suffered from joint pain and impaired range of motion of the hip, knee, elbow and shoulder gradually, associated with difficulty in walking and inability to take care of himself. He was diagnosed with "femoral head necrosis" or "ankylosing spondylitis" in local hospitals, but the treatment of nonsteroidal antiinflammatory drugs (NSAIDs) and sulfasalazine was not effective. Up to the age of 14, the patient displayed normal physical development, with the highest height was about 158 cm, according to the patient recall. However, his height was 153 cm at present. There was no history of similar illness in any family member. Physical examinations descried limitation of movement of almost all joints. Enlargement and flexion deformity of the proximal interphalangeal (PIP) joints of the hands resulted in the claw hand appearance. Limited abduction and internal and external rotation of the shoulder and hip could be find. He had normal laboratory findings for blood routine test, biochemical indexes and acute phase reactants such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Furthermore, HLA-B27 and autoimmune antibodies such as rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP) antibody and antinuclear antibody (ANA) were all negative. X-ray of the hip showed loss of the joint space and irregularities of the femoral head, both femoral head were flattened, it could be see hyperplasia, osteophytes, bilateral femoral neck thicken, neck dry angle turned smaller. The radiological findings of the spinal vertebra indicated kyphosis deformity, narrowing of the intervertebral discs, vertebral syndesmophytes and flattening of the vertebra. However, there was no clues of bone marrow edema in the lumbar MRI. At last, genetic testing for the Wnt1-inducible signaling pathway protein 3 (WISP3) gene was done and indicated compound heterozygous mutations: 756C>G and c.866dupA. These two mutations were derived from the patient's mother and father (the patient's parents each had a heterozygous mutation). Two exons of the WISP3 gene had nucleotide changes leading to amino acid mutations. According to the patient's history, symptoms, physical examinations, radiological findings and genetic testing, the final definitive diagnosis was progressive pseudorheumatic dysplasia.

Spinal instrumentation is a common method for the treatment of spinal disorders, but it can lead to the changes of spine biomechanics. Because of the stress changes, accelerated degeneration of the adjacent segment may occur as time goes by, namely adjacent segment disease. The accelerated degeneration can lead to secondary spinal stenosis, articulated joint degeneration, acquired spondylolisthesis, and spine instability, and some patients may have to receive surgery again. In recent years, the researchers gradually recognized the importance of this disease, and began to investigate its pathogenesis and management.

Unlike meniscal tears and chondral defects, the mucoid degeneration of the anterior cruciate ligament (ACL) is a rare cause of knee pain and there have been no case reports of mucoid degeneration of both the ACL and the posterior cruciate ligament (PCL). A 48-year-old-male patient presented with knee pain and limitation of motion. The patient's magnetic resonance imaging, arthroscopic findings, and pathologic diagnosis confirmed a clinical diagnosis of mucoid degeneration of both the ACL and the PCL. The symptoms disappeared after arthroscopic partial excision of the ACL and PCL.

OBJECTIVETo report the method and result of open arthrolysis of patients who suffered from severe post-traumatic elbow stiffness.

METHODSOf the 12 patients, there were 9 male and 3 female, average age of 32 years old (16 - 47 years). Primary injury included 7 simple fractures, 1 simple dislocation, 2 fracture dislocations and 2 soft tissue injury. The averaged time of immobilization after injury was 3.3 weeks (0 - 8 weeks). The averaged time between injury and open arthrolysis was 6.4 months (1 - 14 months). Before open arthrolysis, the mean arc of total motion was 33.8 degrees (0 degrees - 80 degrees ). Three patients suffered from forearm rotation deficiency. Posterior approach was used for 4 patients, medial approach for 2 patients and both medial and lateral approach for 6 patients. tissues were resected, which hindered the motion of the elbow and perform proximal radioulnar joint arthrolysis for some patients. After arthrolysis, the arc of elbow motion could reach 0 degrees - 140 degrees , and for the patients who suffered from forearm rotation deficiency, pronation 80 degrees and supination 90 degrees were gotten. Ulnar nerve transposition was not a routine. The patients began active and active-assisted elbow and forearm movement the first day after operation. Indomethacin was taken the first day after open arthrolysis routinely.

RESULTSTwelve patients were followed up for 14 - 18 months (averaged 15.8 months). At the latest follow-up, the mean arc of total motion was 120.8 degrees (100 degrees - 140 degrees ). Nine patients recovered the functional arc of 30 degrees - 130 degrees , and 10 patients extended to less than 10 degrees , and 4 patients could extend to 0 degrees . As for the 3 patients who suffered forearm rotation deficiency, the forearm rotation improved. The mean Mayo elbow performance score was 70.4 (50 - 90) before open arthrolysis, and 98.8 (85 - 100) after open arthrolysis. No patient was found to have signs of heterotopic ossification.

CONCLUSIONSFor the treatment of post-traumatic stiff elbow, with careful open arthrolysis and early active and active-assisted exercise we can get good results.
