Background: Instability is one of the most common reasons for revision after a total knee replacement. It accounts for 17.4% of all single-stage revision procedures performed in the UK National Joint Registry. Through a careful patient evaluation, physical assessment and review of investigations one can identify the likely type of instability.
Aims: To critically examine the different types of instability, their presentation and evidence-based management options.
Method: A comprehensive literature search was conducted to identify articles relevant to the aetiology and management of instability in total knee replacements.
Results: Instability should be categorised as isolated or global and then, as flexion, mid-flexion, extension or recurvatum types. By identifying the aetiology of instability one can correctly restore balance and stability.
Conclusion: With careful judgement and meticulous surgical planning, instability can be addressed and revision surgery can provide patients with successful outcomes.

Press-Fit Bone-Anchored Prosthesis for Individuals with Transtibial Amputation.

Radboud University Medical Center, Nijmegen, The Netherlands.
Background: This video article describes the use of bone-anchored prostheses for patients with transtibial amputations, most often resulting from trauma, infection, or dysvascular disease. Large studies have shown that about half of all patients with a socket-suspended artificial limb experience limited mobility and limited prosthesis use because of socket-related problems. These problems occur at the socket-residual limb interface as a result of a painful and unstable connection, leading to an asymmetrical gait and subsequent pelvic and back pain.

Background: In recent years, lateral extra-articular tenodesis (LET) has been shown to be promising in reducing the graft failure rate at short-term follow-up. However, there is a lack of studies investigating the incidence of complications and lateral osteoarthritis (OA) after this procedure, and only a few studies have reported long-term results after anterior cruciate ligament (ACL) reconstruction.
Purpose/hypothesis: This study aimed to compare the failure rate, clinical outcomes, and OA incidence of 3 different ACL reconstruction techniques: single-bundle quadrupled hamstring tendon (HT), bone-patellar tendon-bone (BPTB), and over-the-top HT plus LET (HT + LET).
A blunt needle endoluminal cracking over the strained through-and-through wire for balloon crossing the heavy calcification and chronic total occlusion in critical limb ischemia.

Division of Vascular and Transplant Surgery, Department of Surgery, Faculty of Medicine, Ramathibodi Hospital, Mahidol University, Bangkok, Thailand.
The Achilles heel of revascularization in chronic limb-threatening ischemia is that a balloon is sometimes unable to cross the severely calcified below-the-knee lesion. We presented a new technique for crossing this lesion using the blunt needle endoluminal cracking over the strained through and through wire (BECOST) technique.

Background: Knee Osteoarthritis (KOA) is a prevalent condition worldwide, significantly diminishing quality of life and productivity. Except for the alignment change, muscle activation patterns (MAP) have garnered increasing attention as another crucial factor contributing to KOA.
Objective: This study explores the factors, characteristics, and effects of MAP changes caused by KOA, providing a neuromuscular-based causal analysis for the rehabilitation treatment of KOA.
Recommending Surgery Increases Patient Satisfaction with Arthroplasty Surgeons.

Department of Orthopaedic Surgery, Stanford Hospital and Clinics, Redwood City, California, USA. Electronic address:
Background: Current guidelines recommend shared decision-making in the treatment of hip and knee osteoarthritis, but the impact of individual treatment decisions on patient satisfaction scores is unknown. We hypothesized that clinic Press Ganey satisfaction ratings would be higher for patients who later underwent arthroplasty than patients who did not have surgery.
Methods: Press Ganey satisfaction surveys were obtained from all patient visits at a single academic institution's arthroplasty clinic from 2010 to 2018.
