Introduction: Palmer's disease (or Palmer's syndrome) is poorly understood and is due to traumatic rupture of the internal collateral ligament of the knee at the femoral insertion. Objective: to present three patients suffering from Palmer's disease as a consequence of a traumatic internal collateral ligament injury of the knee at another time. Methods: study of multiple cases of patients treated by arthroscopy in the period from January 2002 to January 2020. Aspects such as age, sex, cause, time to operation and procedure performed were analyzed. The results were evaluated using the visual analog scale for pain and the Lysholm assessment scale. Results: all are young active males, two with right knee injury, two with history of sports trauma and one work-related. Pain, block, knee extension limitation and Böhler, Mc Murray and Apley maneuvers were positive in all patients. There was a significant improvement in the visual analog scale for pain and in the Lysholm scale postoperatively. Conclusions: Palmer's disease is secondary to internal collateral ligament injury that simulates an internal meniscus injury; its diagnosis and resolution are possible with arthroscopy and intensive rehabilitation.

In the osteomuscular system, the knee is one of the part of the inferior members that is most affected, with the consequent limitation or incapacity for deambulation. Objective: To determine the efficacy of rehabilitation and isokinetic exercise before and after partial arthroscopic meniscectomy. Methodology: Prospective, longitudinal research. Pre and post-operatory rehabilitation therapy was applied to 15 patients and rehabilitation therapy plus isokinetic exercise was applied to 17 patients. They were evaluated (starting-pre-post-final) by the SF-36 scale, the Hughston clinic knee, Pain Visual Evaluation, knee articular arc, cuadriceps trophism and muscular strength. Results: Statistical analysis (Student t, Wilcoxon test, chi square) was done by SPSS 15.0. Males were 59.4%, urban inhabitants 81%, Pain Visual Evaluation significantly decreased from 7.5 to 1 point, and both groups improved the articular amplitude and the muscular strength. Cuadriceps trophism increased in patients with isokinetic exercise. Conclusion: Early start of rehabilitation treatment plus or without isokinetic exercise, before and after the surgery, makes sure an efficient recuperation of the patient. [ABSTRACT FROM AUTHOR]

Se ha investigado mucho para determinar las variables clínicas y demográficas que se asocian a los resultados de la meniscectomía parcial artroscópica por rotura meniscal. En este artículo hemos llevado a cabo una revisión bibliográfica para determinar tendencias relativas a los resultados de dicha técnica. Se analizaron las asociaciones entre variables independientes y la evolución; también se revisaron las variables de valoración de los resultados y los métodos de análisis estadístico. Los resultados de estos estudios demuestran que la edad y el sexo del paciente no se relacionan de forma significativa con ninguna de las variables clínicas o radiográficas de valoración de los resultados al cabo de 8,5, 12 y 15 años. Los pacientes que sufrieron roturas con colgajo regresaron a la actividad deportiva más lentamente y necesitaron más reintervenciones que los que sufrieron roturas en «asa de cubo». La artrosis tras la meniscectomía medial parcial progresó más en pacientes mayores de 40 años que en pacientes más jóvenes. No se observó una diferencia estadísticamente significativa entre meniscectomía medial y lateral. En los pacientes con meniscectomía medial los mejores resultados radiográficos se obtuvieron en las rodillas en valgo (en comparación con las rodillas en varo). Las puntuaciones de cartílago aumentadas en el momento de la intervención según la clasificación de Outerbridge modificada se correlacionaron con los peores resultados al cabo de 12 años.

Background: The natural history of a knee subjected to total meniscectomy leads to poor outcomes, so we should be careful with these lesions. Meniscal transplantation may be a proper treatment for these patients as it involves a good medium-term survival. Material and method: We report the case of a 52 year-old male who underwent meniscal transplantation and developed left gonarthrosis. The surgical approach consisted of medial longitudinal arthrotomy and implantation of a posterior stabilized prosthesis after releasing the soft tissues, which were very retracted. Results: At the one year follow-up the operated knee had an articular range of 0-110°, with no gap and no pain; no external support was required for walking. Conclusions: Despite the fact that most case series report good short- and medium-term results, some patients do not have good results and need a total knee prosthesis. [ABSTRACT FROM AUTHOR]
