The Gunston polycentric knee arthroplasty, first designed and performed by Frank Gunston in 1971, is the first prosthesis considering the natural knee biomechanics. Although the polycentric knee arthroplasty showed encouraging results to relieve pain and to preserve the preoperative range of motion and joint instability, the improvements in prosthesis design and arthroplasty technology rapidly made the polycentric knee prosthesis obsolete. Herein, we report a 58-year old male patient who had revision of the Gunston polycentric knee arthroplasty with total knee arthroplasty performed 32 years after the initial operation.

Introduction: Cruciate retaining and posterior stabilizing knee systems are frequently used in total knee replacements. Most researchers compare the results of Cruciate Retaining (CR) and Posterior Stabilizing (PS) knees with those of a control group. The results of using both knee systems in a single patient in simultaneous Total Knee Arthroplasty (TKA) have been studied less.

Total femoral replacement (TFR) is not a common surgery and most indications are for oncological pathologies. However, there are few instances where non-oncological indications might necessitate TFR; this may be a salvage surgery for failed previous hip and/or knee surgeries with consequent significant femur bone loss. We present a 59-year-old obese woman with right thigh pain and difficulty with walking of 5 years duration.

The reported case describes a traumatic anterior knee dislocation of a previous asymptomatic knee after a posterior cruciate-retaining primary knee arthroplasty. The described patient accidentally rolled over her knee six years after the surgical intervention. Anterior traumatic dislocation after knee arthroplasty is an uncommon event often leading to prosthetic's components revision due to its associated ligament injuries.

Femoral nerve palsy (FNP) is a rare but serious complication after total hip replacement (THP). Despite its rarity, FNP can significantly impact patient recovery and quality of life. This case report examines the occurrence of FNP in a patient following a primary THP and highlights the importance of surgical technique and postoperative detection and its management.
