In a prospective clinical examination of 78 knees in 60 young patients with patellofemoral pain, pain occurred frequently in the lateral peripatellar retinaculum, sometimes in association with milder, less well defined medial patellar discomfort. Patellofemoral pain in the young person is frequently a soft tissue problem initially, but aberrant mechanics (particularly lateral tracking) that cause this retinacular overuse and pain may eventually lead to synovial irritation and chondromalacia. Chondromalacia, however, may not be the primary cause of patellofemoral pain in many young people.

Observations of nerve root lesions in spontaneous peripatellar pain led to new aspects concerning the etiology of periarticular pain and chondromalacia patellae. We regard the spontaneous peripatellar pain as an enthesiopathia resulting from an innervation disorder. We believe that also chondromalacia can be caused by nerve root lesions. As a consequence, a change in conservative and operative management is necessary. The aim is a balanced gliding and rotational stability of the patella. This means a muscular compensation of the weakened muscle part and stabilisation of the lumbar and hip region. Surgical techniques should only be applied to normalize the gliding of the patella. There is no indication for ventralisation of tuberositas tibiae.

The maximal isokinetic knee extension strength was measured in 20 patients before and after surgical correction of recurrent dislocations of the patella and the pain evoked during the recordings was rated. The preoperative muscle strength was significantly higher and pain was less severe than in a previously studied group of patients with chondromalacia or patellofemoral osteoarthrosis. Twenty months after patella realignment by a new surgical procedure including an extensive lateral release and anteromedial displacement of the tibial tuberosity by an oblique osteotomy through the anterior crest of the tibia, a significant decrease of patellofemoral pain and a slight increase of muscle strength was noted.

In 30 patients with patellofemoral chondromalacia and osteoarthrosis the maximal isokinetic knee extension strength was measured. The pain evoked during the recordings was rated on a nine-grade scale. The peak extension torques were markedly lower than in the non-diseased knee and in a reference group of healthy volunteers. Twenty months after advancement of the tibial tuberosity, the muscle strength was significantly increased and pain significantly alleviated, well parallelling the clinical improvement. Intra-articular anaesthesia almost instantaneously increased the knee extension torque considerably, although knee pain was unchanged.

The present retrospective study evaluates the clinical, arthroscopic, and follow-up findings in 37 patients with patellofemoral pain syndrome suspected to be a result of patellar tracking abnormality without patellar instability. The results indicate that arthroscopic evaluation of patellofemoral motion is an accurate way to define patellar malalignment. Arthroscopic lateral release gave satisfactory results in 39 of 43 knees. Unsatisfactory results were associated with chondromalacia, prolonged effusion, or painful crepitation.

The static and functional results in a series of 50 patients evaluated at least two years after surgery were gratifying. None had any episodes of functional instability. Forty-six of the 49 who participated in sports prior to operation returned to all desired sports, including six patients who returned to intercollegiate and national team sports. The overall subjective and objective results were 30, excellent; 17, good; one, fair, and two, failure. Of the two failures, one had excellent static stability but significant pain due to pre-existing chondromalacia patella, and the other had a postsurgical neuroma at the lateral surgical site.

In a retrospective review of 184 knees treated for surgically diagnosed chondromalacia of the patella, the average follow-up period was 3.9 years. The treatment rendered included trephine and drilling in 71 knees, facetectomy in 57 knees, shaving in 35 knees, and a combination procedure in 21 knees. Knees were graded as 2, 3, or 4, depending on the depth and severity of the lesion. The best results were in Grades 2 and 3 disease treated by trephine and drilling or facetectomy. Six patients required further patellar surgery during the follow-up period. The purpose of surgical treatment of the patellar articular surface is to relieve pain and preserve the mechanical advantage of the patella for normal knee function.

Five baseball pitchers, three college and two professional, with an average age of 24 years, exhibited pain between the acceleration phase and follow-through phase of the pitching motion. This caused the players to be unable to continue at the level of competition necessary to play. A significant osteophyte on the posteromedial aspect of the olecranon process was identified in all pitchers. This caused impingement with the articular wall of the olecranon fossa and often created an area of chondromalacia. The more commonly identified posterior osteophyte was present in all cases. However, if just this posterior osteophyte is removed, the described lesion will be missed, with resultant persistent disability. Surgical excision of the posteromedial osteophyte through a relatively atraumatic posterolateral approach allowed early return of function without morbidity. With an average follow up of 1 year, all of the pitchers returned for one full season at maximum effectiveness.

Proximal realignment was performed in 75 knees due to patellar pain or instability. With a follow-up period of from two to ten years, the result was excellent or good in 68 knees (91%) and fair or poor in seven knees (9%). Postoperative Merchant views were obtained in 57 knees. In the 52 knees rated good and excellent, the average congruence angle was -11 degrees. Five knees were rated fair or poor, with an average congruence angle of 0 degree. Clinical results seemed to correlate more with correction of patellar congruence than with the severity of chondromalacia found at operation.

Twenty-seven patients were treated with an intraarticular tendon graft reconstruction of the anterior cruciate ligament. The tendon of the extensor of the fifth toe was used in five patients and the tendon of the semi-tendinosus muscle used in 22 patients. Followup ranged from 2 to 9 years, averaging 5.4 years. Fifteen patients remained pain-free, nine complained of only occasional ache, and three had more severe discomfort. One of those patients ruptured the graft postoperatively. Twenty patients were able to return to recreational sports and three to competitive sports. All patients were able to return to their previous occupations. Nine patients had evidence of severe or moderately severe arthritic changes in the injured knee prior to surgery, and an additional five patients had chondromalacia or early arthritic changes. The severity of arthritic changes was directly related to the time interval between injury and reconstruction of the ligament and also to the severity of the injury. Patients with arthritic changes greatly benefited from reconstruction of the ligament. The stability of the reconstructed ligament did not change during the followup if integrity of other ligaments was preserved or reconstructed.
