Magnetic resonance imaging (MRI) of his right knee was obtained, which demonstrated ongoing patellofemoral osteoarthritis with a kissing lesion
involving the trochlea and lateral facet of the patella with subchondral cyst formation.
(2,5,6) Approximately 16-23% of OCLs in the ankle occur in both the talus and the tibia, and while the talus is more susceptible to osteochondral injury, only approximately 2.6% of OCLTP demonstrate adjacent injury to the talus (kissing lesion
" is observed in 10-15% of patients with infective endocarditis of the aortic valve, due to infected jet of aortic regurgitation hitting the ventricular surface of the leaflet [2, 3].
Additionally, it is not unusual in median rhomboid glossitis to have a "kissing lesion
," or area of roughness, most commonly in the area of the hard and soft palate where the tongue generally rests against the palate.
Squamous papilloma is caused by the human papilloma virus (HPV), which has a fronded, irregular surface and may often be pedunculated and multiple due to viral spread in the local vicinity or from upper to lower lid or vice versa, so called kissing lesions
When the lesions occur in body folds like flexor of elbow or axilla, they form kissing lesions
or touching lesions due to contact with two skin surfaces.
The case is unique and intriguing as the young age (26 years) of the patient, disease status (tibiofemoral kissing lesions), and neutral mechanical limb alignment eliminated all traditional surgical treatment options such as HTO or arthroplasty.
A 26-year-old male (height: 1.93 m; weight: 95 kg) presented with neutral limb alignment, painful tibiofemoral kissing lesions, and severe knee OA-related activity limitations due to pain in the left knee of one-year duration (Kellgren-Lawrence grade 2) (Figure 1).
A striking feature is the presence of "kissing lesions" that occur on adjacent surfaces such as the flexor aspects of knee or elbow.
