Aplasia of the posterior cruciate ligament: case report and review of the literature

Abstract

Abstract Hypoplasia or absence of the posterior cruciate ligaments is a very rare congenital malformation. The approach to such cases essentially needs an MRI exam protocol. The management options are variable and require further discussion. CASE SUMMARY: The patient is a 23-year-old Saudi male who has been suffering from pain in the right knee joint starting in the last three months, with an increase in the frequency of right knee pain especially with intentional activities. Magnetic resonance imaging demonstrated an absence/ hypoplasia of the posterior cruciate ligament of the right knee without bone abnormality or subluxation. The patient follows a regular period of physiotherapy per week. CONCLUSION: The diagnosis of posterior cruciate ligament deficiency should be dependent on medical history, patient presentation, and MRI protocol, then appropriate management by a combination of both physical and surgical pathways.
