Clinical and radiographical outcomes of the K-MOD PS total knee prosthesis: a retrospective analysis of 178 cases

Marica Vinci — 2025-12-16

Introduction. The demand for primary total knee prosthesis is growing globally with an annual rate ranging from 5% to 17%, representing the most valid solution in patients with advanced osteoarthritis, providing significant pain relief and an overall improvement in quality of life. Over the years, the evolution of knee prosthetic surgery has led to the development of numerous types of implants, different in materials in design philosophies and surgical approach, with the aim of ensuring the improvement of joint functionality, duration and better adaptation to the patient. The differences concern, for example, the degree of constraint, whether or not the posterior cruciate ligament is preserved and the type of osteointegration. Among the various proposals, PS prostheses are still the most used alternative, based on the “cam-post” system, guaranteeing an improvement of the ROM and a femoral rollback.
Objectives. The aim of this study is to report the clinical and radiographic results of the Biompianti K-MOD PS total knee prosthesis.
Materials and methods. 190 prosthesis implanted between September 2019 and January 2024 were evaluated in 181 patients. The outcome was evaluated through the presence of painful symptomatology, ROM and radiographic aspect, evaluating the presence of possible complications such as mobilization and infection.
Results. Among the 190 implants, 178 were considered for follow up. The 178 prostheses were analyzed retrospectively with an average follow-up of 2.7 years (minimum 7 months, maximum 5 years, SD 1.3). The 88.8% obtained an improvement of the painful symptomatology and a satisfactory final ROM with no signs of mobilization at the radiographic control. 11.2% had complications, including the persistence of painful symptoms with ROM limitation (75%) and aseptic mobilization in 2 cases (10%); a single case of infection and one case of instability to varo-valgus stress were documented.
Conclusions. This study showed an excellent outcome in terms of improved painful symptoms and ROM recovery associated with a low incidence of complications.

Pink pulseless hand in adults: a case report and literature review

Fabrizio Pannucci — 2025-12-31

Supracondylar fractures are among the most common traumatic fractures observed in children.
In the literature, the incidence reported in adult patients is relatively rare. Even rarer is vascular compromise at this level in adults. We present a case of closed distal humerus fracture with pink pulseless hand.

Wrist arthrodesis can provide strong grip strength and stable function after distal radius GCT resection, but at the cost of wrist motion

Lorenzo Fiore — 2025-12-31

Wrist arthrodesis is a well-established and widely used reconstructive strategy following resection of a giant cell tumor (GCT) of the distal radius, particularly for aggressive or recurrent lesions. This literature review explored the functional outcomes and stability associated with this procedure.
The research, which included the analysis of 50 relevant studies, consistently demonstrated that arthrodesis provides reliable oncological control and effectively restores grip strength (generally 65-74% of the contralateral side) and mechanical stability. Despite the complete sacrifice of wrist flexion and extension, most patients maintain adequate forearm rotation, which allows them to perform the majority of daily activities.
The reported functional scores are generally excellent (MSTS scores ranging from 22 to 29), and DASH and PRWE scores indicate minimal disability and high patient satisfaction.
Arthrodesis is often preferred in patients with high functional demands or those engaged in heavy manual labor.
The main disadvantage is the permanent loss of motion, but this limitation is compensated by durable stability and the absence of pain. In conclusion, wrist arthrodesis is an effective and reliable solution for functional restoration, balancing oncological safety with robust hand function. The final choice of reconstruction must be personalized based on the tumor grade and the patient’s needs.
