Widespread misuse of the term chondromalacia has led to confusion regarding its true meaning. This term should not be used to diagnose patellofemoral pain, but to describe lesions of articular cartilage. Recent advances using stereophotogrammetry to evaluate the patellofemoral joint and its articular cartilage may lead to new insight into the etiology of these lesions.

In patellofemoral disorders, some cases respond well to conservative management thus the authors' initial treatment is conservative. The Patellar Band (PB) was reported previously (Nakamura et al., 1987). Since then the indications for the band have been investigated. Sixty four patients treated by the PB without operative treatment were classified into eight groups. The Severity of Dysfunction (SOD) was assessed by three grades. The First Grade is dull pain after walking or running for a long distance, the Second Grade is sharp pain on climbing up and down stairs, the Third Grade is a feeling of insecurity. The grouping was as follows: Group Ia - plica syndrome with first Grade of SOD and Ib with Second Grade of SOD. Group IIa - chondromalacia with First Grade of SOD and IIb with Second Grade of SOD. Group III - maltracking patella with patellar pain on flexion. Group IVa - subluxation or dislocation of patella with no previous history of patellar symptom and IVb - recurrent dislocation. Group V - degenerative change of the patella. The PB has been proved to be most effective in Groups Ia, IIa and IVb although it is beneficial in half the cases in Groups IIb and III. The subluxation of the patella was partially reduced without recurrence of dislocation during sports activity and the feeling of insecurity was relieved by the PB. The overall results were not related to age or activity level of the patient. The indication of the band for painful knees was not clearly determined in this study. In all operated cases, it was effective for postoperative instability after lateral release of the retinaculum.

The results of 50 arthroscopic lateral releases are reported. The average follow-up period was 36 months with a range of 18-52 months. Satisfactory results were achieved in 71% of 21 patients with patellar pain alone and in 76% of those (Betz RR, Lonergan R, Patterson R. The percutaneous lateral retinacular release Orthopaedics 1982;5:57-62) with instability. Patients with patellofemoral osteoarthritis or patellar dislocation were excluded from the series. Postoperative hemarthrosis occurred in 10%. Unsatisfactory results could be related to incomplete release, severe chondromalacia, or insufficient rehabilitation. Lateral release is capable of producing high rates of success with a low incidence of complication when used to treat patellar pain with tight retinaculum, patellar instability, and subluxation.

A randomized, double blind study of low level laser treatment of chondromalacia of the patella in 40 patients has been undertaken. Chondromalacia was established by arthroscopy and was related to subjective symptoms. Eight treatments were given during five weeks by a physiotherapist with the use of a GAAS pulsed laser, real or sham. Assessment of the location, quality and intensity of pain, and the influence on mood, gait, sleep, work, and sports was made before and after treatment including an eight to twelve week evaluation. No statistical difference was found between real and sham use of low level laser for the symptoms of chondromalacia of the patella.

The patellofemoral joint is one of the most common sources of painful symptoms encountered by athletes and is one of the most frequently injured joints. Patellar incongruency is the primary pathologic condition that affects the patellofemoral joint and has been reported to be associated with patellar subluxation, patellar dislocation, chondromalacia, and arthrosis. The diagnosis of patellofemoral incongruency by physical examination alone is extremely difficult because the clinical signs may stimulate other types of internal derangements of the knee, and there is a high incidence of combined abnormalities. In consideration of these issues, a kinematic MRI technique was developed to identify and characterize abnormal anatomic and functional aspects of the patellofemoral joint. Because the patellofemoral joint is often injured in athletes and patellofemoral incongruency is a common site of their pain, this article will discuss the use of kinematic MRI to assess the anatomy and function of the patellofemoral joint, with an emphasis toward special problems that may be found in relation to sports-related activities.

We studied all patients undergoing arthroscopic resection of symptomatic plica without other intraarticular abnormality at our institution from October 1981 to March 1987. To be considered abnormal, plicae had to be thickened and/or fibrotic when viewed arthroscopically. Seventy-six of nearly 2000 patients (4%) who underwent diagnostic arthroscopies met our inclusion criteria. Clinical response after arthroscopic resection was evaluated in 51 patients at an average of 47 months (range, 15 to 77). Excellent or good results were obtained in 57 (75%) of the patients. Eleven patients (14%) had an impingement lesion defined as a localized femoral condylar ridge or groove of the articular surface that impinged upon the plica with increasing flexion. All of these patients had an excellent or good result. Other factors associated with a favorable outcome included a specific preoperative diagnosis localizing symptoms to the medial compartment, onset of pain after a period of increased athletic activity or after a twisting injury, and younger age. Poor prognostic factors included associated chondromalacia and an unclear preoperative diagnosis.

Spontaneous osteonecrosis about the knee typically is a disease of the elderly characterized by an acute onset of pain. The exact cause of this condition has long been debated, although a causative relationship between meniscal tears and spontaneous osteonecrosis about the knee has been postulated. Seven patients with knee pain, meniscal tears, and chondromalacia without initial evidence of osteonecrosis at magnetic resonance (MR) imaging underwent arthroscopic surgery with meniscal recontouring or repair and cartilage shaving. These patients returned within 2-14 months with recurrent pain in the treated knee. MR imaging then demonstrated abnormalities consistent with osteonecrosis. Osteonecrosis of the femoral condyle or tibial plateau may be a late sequela of meniscal injury in association with chondromalacia and arthroscopic surgery. This diagnosis should be suspected in patients with recurrent knee pain after arthroscopic repair of meniscal tears. The precise relationship of this pattern of osteonecrosis to that previously described as spontaneous requires further investigation.

The treatment of chondromalacia of the patella is a medical problem. There are no sure concepts of therapy. We have analysed the value of the only lateral release or shaving by motorizised instruments or the combination of both methods. After lateral release have many patients no pain but the other methods also helped many patients. The comparison of these groups is impossible because of the different structure. A prospective randomised study has to bring the answer to this question.

A new operative technique in arthroscopic treatment of chondromalacia using ultraviolet laser systems is introduced. The postoperative results are evaluated in a prospective and randomized clinical trial. One hundred and forty patients stage II or III chondromalacia according to Outerbridge were randomly assigned to arthroscopic operation using either laser or mechanical instruments. After a 6-month follow-up period the clinical results were compared, guided by a specially designed modification of the Lysholm scoring scale. In the short-term follow-up laser surgery gave superior results in regard to reducing pain (P less than 0.05) and leading to a lower incidence of reactive synovitis (P less than 0.01). No difference was found in respect of disability and functional impairment. Our results lead to the conclusion that arthroscopic laser application seems to be a successful procedure in the treatment of degenerative cartilage disorders, providing precise ablation of tissue without significant thermal damage to the remaining cartilage.

Wrist arthroscopy was done for one hundred nine patients with chronic wrist pain, averaging 22.8 months in duration. History regarding mechanism of injury, painful crepitus, pain with activity or at rest, localization of tenderness, visible swelling, and instability with examination was compared with arthroscopic findings of ligament damage, articular cartilage damage, and synovitis. Both pain at rest and swelling correlated significantly with synovitis. Tenderness did not correlate with specific ligament injury. Wrist ligament injuries and/or cartilage damage were noted in 96.3% of these wrists. Ligament injuries were frequently multiple, averaging 2.6 ligament injuries per wrist. No significant association was found between the presence of chondromalacia, synovitis, or specific ligament tears and the mechanism of injury, duration of symptoms, presence of clicking, or pain with activity.
