“…Ein offenes oder arthroskopisches laterales Release hat sich ebenfalls nicht als suffiziente Methode zur Behandlung chronischer patellofemoraler Instabilitä-ten oder rezidivierender Patellaluxationen erwiesen [4]. Zudem kommt es durch das laterale Release zu einer vermehrten patellofemoralen Instabilität [7].…”

“…Similarly, 17 of 18 knees initially Correlation of postoperative results with preoperative findings rated good remained in that category. The conclusion from this is that a patient with an initial good or excellent result 1 year after open lateral release will most likely retain that rating for some years (Table 4). Patients with bilateral procedures all had good to excellent results.…”

The purpose of this study was as follows: 1) to review our previous findings regarding surgical outcome following open retinacular release but now at a mean followup of 4 years, 2) to test the validity of the correction of patellar "overhang" by Merchant views at 4 years and correlate this with outcome, 3) to correlate arthroscopic findings of lateral overhang, patellofemoral cartilage disease, preoperative Q-angle measurements, and duration of symptoms with outcome at 4 years postrelease. The surgical technique of diagnostic arthroscopy and open longitudinal release has been described previously by the author, emphasizing the specific anatomical structures to be divided. The synovium was never incised and the retinacular structures were freed to allow reduction of the patella medially. Sixty patients comprising 76 knees were reviewed at a mean followup of 4 years postrelease. Followup included evaluation of Merchant views and Q angles, physical examination, and determination of patient satisfaction. Eighty-five percent of the patients followed retained the good to excellent ratings they had at the 2 year followup. "Reduction" of the released patella on Merchant views correlated well with surgical outcome and patient satisfaction in 95% of cases. Residual Merchant view patellar tilt or excessive lateral position correlated well with poor results. Hematoma formation was the leading cause of failure. A severe preoperative Q angle correlated somewhat with results at 4 years but this was not statistically significant. The degree of articular cartilage disease at prerelease arthroscopy did not correlate at all with results at 4 years, nor did the duration of preoperative symptoms.(ABSTRACT TRUNCATED AT 250 WORDS)

“…MPS was first described in 1987 by Betz et al as a complication of lateral retinacular release [10]. Since then, Hughston et al reported medial subluxation in 50% of knees with recurrent patellar dislocation in which arthroscopic lateral retinacular release was performed [11].…”

Medial Patella Subluxation after Minor Trauma

Most cases of medial patella subluxation occur under iatrogenic conditions that are often associated with a prior excessive lateral retinacular release procedure. We report a case of medial subluxation following minor trauma with no history of previous lateral release. The abnormality was identified on magnetic resonance imaging and was successfully treated by direct repair of the lateral retinaculum. The recognition and treatment of medial subluxation of the patella without retinacular release can be difficult. Therefore, consideration of multiple causes through careful medical history taking, physical examination, and radiologic examination is needed for accurate diagnosis.
