Sinding Larsen-Johansson syndrome is an osteochondrosis injury of patella commonly seen in adolescence age group between 10 to 14 years old. This is an interesting case of Sinding Larsen-Johansson syndrome reported in 33 years old football athlete. This is 33 years old football athlete who is active in participating many football tournaments for 18 years presented with anterior knee pain for 1 month subsequently had traumatic sports injury in one of the football matches. He was diagnosed with complete anterior cruciate ligament rupture, with medial and lateral meniscus injury. MRI confirmed the diagnosis with additional finding of chronic Sinding Larsen-Johansson syndrome. He was rested from football match, and had an intensive physiotherapy focusing on eccentric muscle strengthening exercise. The symptom of anterior knee pain was improved with improvement of the instability. This article discussed in detail on Sinding Larsen-Johansson Syndrome.

Background: Anterior knee pain is a frequent condition after anterior cruciate ligament reconstruction (ACLR), but its origin remains uncertain. Studies have suggested that donor site morbidity in autologous bone–patellar tendon–bone reconstructions may contribute to patellofemoral pain, but this does not explain why hamstring tendon reconstructions may also present with anterior pain. Purpose: To evaluate the prevalence of anterior knee pain after ACLR and its predisposing factors. Study Design: Case-control study; Level of evidence, 3. Methods: We evaluated the records of all patients who underwent ACLR between 2000 and 2016 at a private facility. The prevalence of anterior knee pain after surgery was assessed, and possible risk factors (graft type, patient sex, surgical technique, range of motion) were evaluated. Results: The records of 438 patients (mean age, 30 years) who underwent ACLR were analyzed. Anterior knee pain was found in 6.2% of the patients. We found an increased prevalence of anterior knee pain with patellar tendon graft, with an odds ratio of 3.4 ( P = .011). Patients who experienced extension deficit in the postoperative period had an odds ratio of 5.3 of having anterior pain ( P < .001). Anterior knee pain was not correlated with patient sex or surgical technique. Conclusion: The chance of having anterior knee pain after ACLR was higher when patellar tendon autograft was used compared with hamstring tendon graft, as well as in patients who experienced extension deficit in the postoperative period.

Mucoid degeneration of the anterior cruciate ligament (ACL) is a rare cause of anterior knee pain (AKP). Some case reports have been published; however, it is difficult to diagnose and is often underdiagnosed or misdiagnosed because of its pathophysiological ambiguity. We report a rare case of a patient diagnosed with bilateral mucoid degeneration of the ACL with AKP and no limited joint range of motion (ROM). A 59-year-old man with spontaneous right AKP was admitted to our hospital. He first underwent arthroscopic resection of the thickened medial plica protruding far into the medial patellofemoral joint (PFJ) but felt little effectiveness thereafter. He then had an arthroscopic release of the lateral patellar retinaculum because of valgus knee and patellar instability, which resulted in only temporary improvement. Then, the AKP relapsed, this time with limitations in the ROM. Magnetic resonance imaging (MRI0 showed a diffuse, thickened ACL with a high inhomogeneous intensity in the T2-weighted and proton density weighted images and which looked similar to a celery stalk. Based on the patient’s history and MRI findings, we suspected mucoid degeneration of the ACL and subsequently performed arthroscopic excision. At the same time, AKP appeared on the other side. Since the MRI demonstrated a similar celery stalk image as before, the same operation was performed on this side, as well. Finally, AKP and the limitation of the ROM were relieved approximately one month after surgery. Due to the patient only suffering from AKP with a preserved ROM, it took about 14 months to diagnose this disease. It should, therefore, always be considered in cases of AKP alone.
