The overwhelming success of total knee arthroplasty (TKA) has rapidly increased its utilization. 1,2) Initially, the procedure was largely meant to relieve pain and preserve mobility in the elderly, but it has expanding the spectrum of usage to include a younger, demanding population. Its significant effect on improving quality of life has made enormous socioeconomic impact. To optimize outcomes of TKA, there have been rapid advances in each aspect of the surgery, including preoperative patient optimization, precise surgical technique, effective pain control, and expeditious rehabilitation. 2) Even with these changes, 10%−15% of patients remain dissatisfied. 3) One of the reasons for dissatisfaction is presumed to be altered kinemat

We report our experience of using autologous chondrocyte implantation (ACI) to treat osteochondral defects of the knee in combination with anterior cruciate ligament (ACL) reconstruction. The outcome of symptomatic osteochondral lesions treated with ACI following previous successful ACL reconstruction is also reviewed. Patients were followed for a mean of 23 months. Nine patients underwent ACL reconstruction in combination with ACI. Mean modified Cincinnati knee scores improved from 42 to 69 following surgery. Seven patients described their knee as better and two as the same. A second group of nine patients underwent ACI for symptomatic articular cartilage defects following previous ACL reconstruction. In this group, the mean modified Cincinnati knee score improved from 53 to 62 after surgery. Six patients described their knee as better and three as worse. Combined treatment using ACI with ACL reconstruction is technically feasible and resulted in sustained improvement in pain and function. The results following previous ACL reconstruction also resulted in clinical improvement, although results were not as good as following the combined procedure.

Background:Infection after anterior cruciate ligament reconstruction surgery (ACLRS) is a rare complication. Although there are number of studies from various Caucasian population but only few studies are available from Asian population. The aim of the study is to assess the incidence, risk factors and, clinical outcome using our treatment protocol.Materials and Methods:Out of 1468 arthroscopic ACLRS, 26 patients with clinical suspicion of infection were critically analysed in terms of laboratory reports of arthrocentesis, erythrocyte sedimentation rate, C-reactive protein and risk factors such as the type of graft, gender, diabetes mellitus, smoking, intraarticular steroid injection, and obesity. At final followup, all these patients were evaluated using visual analog scale (VAS), Lysholm knee score, and Tegner activity level.Results:In nine patients, culture did not show any growth and they showed improvement with arthrocentesis and oral antibiotics. These patients were labeled as suffering from aseptic effusion. In the remaining 17 patients, there was no clinical improvement or instead worsening of symptoms after arthrocentesis and oral antibiotics. These patients were labeled as suffering from an infection and underwent surgical debridement along with administration of injectable antibiotics. The history of intraarticular steroid injection before ACLRS was a significant risk factor for developing infection (P = 0.001). At mean followup of 2.8 years, mean VAS improved to 1.18 ± 0.99 from 6.2 ± 2.3. The mean Lysholm knee score and Tegner's activity level at the final followup were 79.2 ± 10.52 and 4.8 ± 2.30, respectively.Conclusion:The incidence of infection was 1.2% (17/1468). The step-ladder approach of differentiating between aseptic effusion and infection and accordingly, following a treatment protocol, i.e., oral antibiotics alone or surgical debridement along with injectable antibiotics or additional debridement of graft in refractory patients, yielded satisfactory results.

Background:The debate about the ideal surgical procedure for acromioclavicular joint (ACJ) dislocation is still unresolved and newer techniques are being evolved continuously. The present study evaluates functional outcome of ACJ reconstruction using the modified Weaver Dunn procedure.Materials and Methods:35 patients (26 males, 9 females) with ACJ dislocation, between the age group of 18–48 years (mean age 31 years), were operated using modified Weaver Dunn procedure at our center from May 2005 to June 2010. The dominant side was involved in 25 patients (22 right, 13 left). The mean period from the time of injury to the surgery was 14 days (range 4–26 days). All the patients were assessed with Oxford shoulder score and the time required to return to preinjury level was recorded.Results:At the mean followup of 95 months (range 72–120 months), the mean Oxford Shoulder Score improved from 25 ± 7.2 to 43 ± 6.9. 85% (30 out of 35) patients had satisfactory results, while 15% (5 out of 35) had mild shoulder dysfunction using this scoring system. Five patients had radiological evidence of Grade 2 ACJ subluxation. Out of these five patients, two developed ossification around the coracoclavicular ligament. Three patients had intermittent mild pain without any functional disability, and one had a moderate restriction of shoulder movements.Conclusion:ACJ reconstruction, using the modified Weaver Dunn procedure in ACJ dislocation, is a reproducible procedure and provides a good functional outcome.

The objective of this study is to discuss the fact that whether graft rupture after successful anterior cruciate ligament (ACL) reconstruction surgery is due to graft failure or re-injury to the reconstructed ACL. Methods: In total, 340 sportspersons, meeting our inclusion criteria, were assessed for rupture of ipsilateral ACL graft and ACL injury of the contralateral knee. Patients with ipsilateral ACL graft rupture were labelled as group 1, while those with contralateral ACL injury were labelled as group 2. Both groups were compared for potential risk factors for ACL injury, and statistical analysis was performed to study whether the graft acted as an additional risk factor. Results: Of the 340 sportspersons, 25 patients suffered a total of 26 injuries. Ipsilateral graft rupture rate was 2.4% (8 of 340) at a mean follow-up of 25.5 + 40.57 months, and the contralateral ACL injury rate was 5.3% (18 of 340) at a mean follow-up of 18.11 + 19.97 months, with an overall re-injury rate of 7.6%. Both groups were comparable for risk factors for ACL injury: age (p ¼ 0.255), gender (p ¼ 0.534), mode of re-injury (p ¼ 0.523), level of sports activity, type of graft used (p ¼ 0. 918), graft diameter (p ¼ 0.607), duration from injury to index surgery (p ¼ 0.492), duration from index surgery to re-injury (p ¼ 0.638), timing of return to sports after index surgery (p ¼ 0.303), duration of sporting activity before second injury (p ¼ 0.657), and Tegner's level of sports activity (p ¼ 0.486). Conclusion: Because the rate of contralateral ACL injury is higher than the ipsilateral graft rupture and the risk factors for ACL injury are comparable in both groups at a follow-up period, which is suggestive of ligamentization of the graft, we suggest that it might be an ACL re-injury rather than graft failure.
