Primary synovial chondromatosis is characterized by newly formed chondral or osteochondral nodules in the synovial membrane, which may detach and form loose bodies. The loose bodies can be calcified or ossified, and the condition is termed synovial osteochondromatosis. Three distinct stages can be identified in primary synovial chondromatosis : phase I is active synovitis without loose bodies, phase II shows nodular synovitis along with loose bodies, and phase III is characterized by the presence of loose bodies with the resolution of synovitis. Surgical treatment has been recommended as the first choice of therapy in phases II and III disease. Complete synovectomy and removal of all loose bodies is advisable for prevention of recurrence of the disease. In this technical note, the technical details of arthroscopic removal of loose bodies and synovectomy for the management of synovial osteochondromatosis of the elbow is described. Compared with open procedures, the arthroscopic approach has many advantages, including a shorter rehabilitation period and higher patient satisfaction.

The current treatment of choice for diffuse-type pigmented villonodular synovitis (PVNS) is surgical excision. Complete synovectomy is necessary because of the local aggressiveness of the disease, with a significant recurrence rate and a minor chance of malignant transformation. The recurrence rate is even greater in those cases with extra-articular extension. Arthroscopic and endoscopic synovectomy have the advantage of avoidance of extensive soft-tissue dissection, which is associated with open synovectomy. The purpose of this Technical Note is to describe the details of combined arthroscopic and endoscopic synovectomy as treatment for diffuse PVNS of the ankle. By a combination of different arthroscopic and endoscopic approaches of the ankle region, a complete synovectomy of both intra-articular and extra-articular components of diffuse-type PVNS is feasible.

Synovial disease is a common reason for hip joint dysfunction. Although traditionally treated with open synovectomy, with the popularization and development of arthroscopic techniques, arthroscopic synovectomy has become the main surgical treatment for synovial diseases. Given the long soft tissue channel and learning curve, arthroscopic synovectomy of the hip joint has high surgical requirements for surgeons. However, there is currently no standardized surgical protocol for arthroscopic synovectomy of the hip joint to guide the surgeon to perform hip synovectomy in an orderly manner. During the past 3 years, we have employed a novel technique, wherein we divided the synovium of the hip into seven regions based on the anatomical structure and the operating range of the arthroscopic portals. With the assistance of flexion, extension, and traction of the hip joint, synovectomy was sequentially performed under arthroscopic guidance. This regional surgical technique can be popularized and likely has the potential to become a standardized arthroscopic synovectomy protocol of the hip joint.

Synovial chondromatosis is a benign metaplastic disease of the synovial joints, characterized by the development of cartilaginous nodules in the synovium. Treatment generally includes open or arthroscopic loose body removal combined with a synovectomy. An all-arthroscopic approach has been described to minimize complications and reduce morbidity while providing adequate control of local disease. The purpose of this Technical Note is to describe our techniques and technical pearls that allow for adequate excision of disease while minimizing complications and disease recurrence. The combination of patient positioning, the establishment of multiple arthroscopic portals to ensure optimal visualization and freedom of instruments, the use of a leg holder, and the use of a variety of surgical instruments to facilitate loose body removal and synovectomy is critical to optimize clinical outcomes and minimize complications. Although technically demanding, our described technique can help facilitate extensive loose body removal and complete synovectomy.

Tenosynovial giant cell tumors (TGCT) are a rare group of generally non-malignant tumors that involves the synovium and tendon sheath. A young female patient presented to the outpatient department with a complaint of unilateral knee swelling and pain. She was evaluated as such and based on a provisional diagnosis of benign synovial proliferation, she was treated with an arthroscopic resection. We discuss our case and discuss the possible medical therapies to prevent recurrence.

Review
The arthroscopic treatment of arthritis of the ankle joint is very limited and is only indicated for early stages of arthritis with impingement, strictly localized forms and more for young patients. The most important aim of arthroscopy is to improve the range of motion (ROM) of the ankle by removal of bony projections (dorsal and ventral) and an extensive synovectomy with debridement. In cases of narrowing of the joint space to less than 2 mm and/or malalignment, the indications for arthroscopy should be considered very cautiously. This is independent of the localization of the narrowing, especially if the complete joint is affected. If necessary, arthroscopy can then be carried out as an additional intervention in cases of conversion osteotomy in order to improve the ROM.

Review
OBJECTIVE
To describe the indications, operative technique, and long-term outcomes of patients treated with the Scheker (Aptis) distal radio-ulnar joint (DRUJ) prosthesis.
INDICATIONS
The Scheker prosthesis is intended to replace the DRUJ in patients with rheumatoid, degenerative, or posttraumatic arthritis of the sigmoid notch and/or ulnar head, or in cases of gross instability of the DRUJ. Moreover, a Scheker prosthesis can be used to treat failed salvage procedures, such as the Sauvé-Kapandji procedure, ulnar head resection, and ulnar head arthroplasty.
CONTRAINDICATIONS
Severe osteoporosis, active infection, immature skeleton, less than 14 cm of the proximal ulna remaining.
SURGICAL TECHNIQUE
In supine position with the forearm in full pronation, an ulnar S‑shaped incision is made. The ulnar head is resected and the proximal part is brought to the palmar side to enable visualization of the sigmoid notch. Following preparation of the sigmoid notch and the proximal ulnar part of the radius, a radial plate is attached. When the position is verified with fluoroscopy, screw holes are drilled together with a separate hole for the radial peg. A metal stem is inserted in the ulnar shaft. A polymer ball is then slid on to a polished peg on top of the ulnar stem. This polymer ball is seated in the socket of the radial plate and fixed with a small metal cap. Radiographic images are made for confirmation of correct positioning and full pro- and supination is tested, after which the wound is closed.
POSTOPERATIVE MANAGEMENT
After 48 h of pressure bandages, patients are instructed to start with full range of motion and weight-bearing exercises under the guidance of a hand therapist. Weight-bearing is constrained to 10 kg.
RESULTS
We retrospectively assessed 50 Scheker prostheses in 48 patients treated between 2016 and 2021. The median age was 56 years (IQR: 50-65) and 30 (60%) were female. Median follow-up was 29 months (IQR: 12-48). The primary outcome was the PRWE score. The median PRWE score at the final follow-up was 23 (IQR: 4-52) for the operated side versus a median PRWE score of 5 (IQR: 0-25) for the non-operated side (p < 0.005). Six patients had a complication. Three patients developed extensor carpi ulnaris tendinitis with one patient requiring additional surgery. One patient developed a neuroma of the distal branch of the ulnar nerve that was surgically removed. One synovectomy was performed because of synovitis and one endoscopic ulnar release was performed because of hyperesthesia of the ulnar area. None of the prostheses had to be removed.

Synovial osteochondromatosis or synovial chondromatosis is a benign joint pathology characterized by the development of multiple cartilaginous nodules or loose bodies in the synovial membrane that typically arise in the larger joints of the body. It usually presents as joint pain and, as seen in the present case, can occasionally be missed. Diagnosis involves a combination of clinical evaluation, imaging studies, and histopathological evaluation (which is confirmatory). Treatment depends on the severity of the disease, symptoms, and the patient's social situation, and may include monitoring for asymptomatic cases, non-surgical management (pain medications and physical therapy), or surgical intervention. Surgical intervention may include arthroscopic removal of loose bodies, synovectomy, or reconstruction/replacement in severe situations. Prognosis has a direct relationship to how early the disease is diagnosed. Early intervention with appropriate management can help alleviate symptoms; however, if left unmanaged, it can lead to joint damage and osteoarthritis or very rarely, malignant transformation into chondrosarcoma. This report describes the case of a 62-year-old female with complaints of bilateral knee pain who was originally diagnosed with osteoarthritis based on clinical exam and X-rays. Two magnetic resonance imaging (MRI) scans were done three years apart, with synovial osteochondromatosis being on the differential after the second scan. A left knee major synovectomy was conducted after the second MRI reading, where rubbery masses of tissue along with loose fragments were removed. Fluid from the tissue masses was sent to culture and pathology for interpretation. Two weeks post the surgery, the patient's pain improved tremendously, with adequate ambulation independently. Histopathology came back positive for synovial osteochondromatosis. This case report highlights the importance of keeping this joint pathology on the differential when treating patients with joint pain and interpreting imaging.

The wrist is the fourth most common joint to be involved in juvenile inflammatory arthritis (JIA), which is a common rheumatological condition affecting children. Wrist arthroscopy is well established in rheumatoid arthritis, but remains unexplored in JIA. The aim of this study is to investigate the role of wrist arthroscopy in JIA, with focus on those who are refractory to medical management. This is a prospective observational study, including consecutive patients with JIA undergoing arthroscopy between January 2016 and December 2020. Those over the age of 18 years and those with other rheumatological diagnoses were excluded. Data including pre-, intra-, and postoperative variables, demographics, and patient-reported outcomes were collated and are reported using standard measures. A total of 15 patients underwent arthroscopy ( = 20 wrists). Synovitis was noted in all wrists on arthroscopy and synovectomy was performed in all cases. Other procedures were performed as indicated during the procedure. The median follow-up duration was 11.3 (interquartile range [IQR] 8.1-24.2) months. Median reduction of 4 (IQR 2.25-6) points on the Visual Analogue Score for pain on loading was noted postoperatively. Grip strength was improved in = 11/20 wrists and functional improvement was noted in = 18/20 wrists. Restriction of range of motion was achieved with a shrinkage procedure in patients with hypermobile joints. There were no postoperative complications, and no patients were lost to follow-up. In experienced hands, wrist arthroscopy is feasible, safe, and efficacious in the management of JIA, among patients who are refractory to medical management. This is a Level II study.

Knee arthroscopy has evolved greatly from its inception in the 20th century. Arthroscopic synovectomy is performed in the case of infection or significant synovitis. We continue to develop more minimally invasive procedures, and the NanoScope (Arthrex, Naples, FL) has provided a new generation of possibilities. The system does not require the use of a standard incision or portal, and using the GraftNet (Arthrex), we can harvest tissue with a standard shaver for further evaluation. This technique provides an option to perform a synovectomy and biopsy without the use of standard arthroscopy portals through an incisionless approach.
